A Brief History Of PDM PDM entered the steel service center industry in 954 with the acquisition of the Proctor-James Steel Company in San Jose, California. In 955, Kyle & Company was purchased, with facilities in Fresno, Stockton, and Sacramento. With four service centers, PDM was able to provide outstanding service throughout central and northern California. In 962, a new facility was constructed in Fresno, California. In 968, the existing operations were greatly augmented by the completion of a large, state of the art service center in Stockton, California. The most modern material handling equipment and strategies available were used in this facility. In 974, a new warehouse was built in Sparks, Nevada to improve service in the central, northern California, and northern Nevada areas. To provide the greatest possible service and selection to customers, a Common Inventory Concept was adopted which provided customers throughout the company, access to uncommon, hard to find, slow moving items, without the burden of carrying duplicate inventories in each location. Under the Common Inventory Concept, the new Stockton facility became the geographical hub of the service wheel with spokes running east to Sparks, south to Fresno and west to Santa Clara. The Interplant Transfer System was developed to quickly move this common inventory between service centers, providing short lead-time delivery of most items regardless of the inventory location. This concept proved to be so successful that future PDM operations were either built or expanded to provide other hub type distribution facilities. In 977, a new service center was established in Spanish Fork, Utah, south of Salt Lake City. This location was expanded several times to meet market demands. It is now a full line distribution and processing facility acting as the hub for the Intermountain Region while providing service for customers in Utah, Idaho, Wyoming, Montana, Colorado, and New Mexico. In January 997, PDM purchased General Steel, a carbon steel service center in Vancouver, Washington. In April of 999 this operation moved into a newly designed facility in Woodland, Washington and became the next hub in the Great Northwest. The Woodland service center serves Washington, Oregon, and parts of Idaho, Alaska and Canada. In July 200, Reliance Steel & Aluminum Co. of Los Angeles, California purchased PDM Steel Service Centers. Today PDM Steel operates as a wholly owned subsidiary now named: PDM Steel Service Centers, Inc. PDM entered the Las Vegas market in late 200 working from a remote Page 4

office with delivery supplemented through both Fresno and Spanish Fork. By early 2005, the company moved into a small full-service warehouse with delivery throughout Southern Nevada and into Southern Utah. In March of 2008, a transfer yard and sales office were established in Grand Junction, Colorado to aid the company s expansion from the Spanish Fork facility into Colorado and New Mexico. INTRODUCTION By May of 2008, PDM acquired Engbar Pipe and Steel in Denver, Colorado. With support of regular delivery and a vast inventory from the Spanish Fork operation, PDM Denver expanded their service and product offering to the greater Colorado market and parts of Wyoming. PDM built and moved into a new, state of the art facility in Las Vegas in August 2008. This operation now houses a complete product offering with multiple processing capabilities. PDM Las Vegas serves the Southern Nevada market and parts of Utah, Arizona, and California. Since 2000, as demand for pre-production processing material grew, the company responded by investing new processing equipment installed at all facilities. State of the art automatic saws with controlled feed-in and feed-out tables and enhanced plate burning equipment have been upgraded in almost all locations. In 2008, the company purchased a multifunction precision plate processing center and located it in Fresno. In 200 a second center was located in Spanish Fork. These processing centers provided improved thermal cutting capabilities and multifunction processes, like drilling, punching, taping, scribing and marking all on one machine. In that same year, PDM installed a 20 ton iron worker in Fresno augmenting the production of plate and small structural parts. The following year, in Fresno, a,000 ton x 24 press brake was installed bringing heavy plate forming to PDM. Then in 202, the company further expanded by adding two multi axis beveling machines in Fresno and a laser cutting machine in Sparks. Continuing the company s consistent pattern of growth, in July of 202, a stocking satellite was opened in Boise, Idaho, which is supplemented from the Spanish Fork facility on a regular basis. PDM Steel Service Centers, Inc. is constantly evaluating opportunities to improve service, inventories, and delivery in existing facilities and has an on-going program to explore opportunities for expansion into new markets. Our pledge to you in the future, as in the past, will be to provide you with the finest.. Service When And Where You Need It! Page 5

Bar Size & Structural Shapes Structural shapes are those whose greatest dimension, not including length, is three inches or greater. Applications ASTM A6 is utilized in riveted, bolted or welded construction in a wide variety of products such as bridges and buildings. ASTM A572 Grade 50 (high strength, low alloy) structurals are intended for use in riveted or welded fabrication of bridges, buildings and other critical structures where greater strength is required. High Strength, Low Alloy shapes provide excellent strength to weight ratios and in some cases, improved resistance to atmospheric corrosion. ASTM A992 wide flange beams are dual specification, meeting the requirements of ASTM A6 and of ASTM A572 Grade 50. Weldability When any grade of steel is used in welded construction, procedures must be suitable for the steel and the intended service. ASTM A6 steel presents no welding problems when using all welding processes. The quality of the welds is generally extremely high for both welds and joints. Welding rod specifications are dependent on welding conditions such as the thickness of the sections to be welded, service requirements and design. High Strength, Low Alloy grades such as A572 Grade 50 and A992 Grade 50 are weldable with welding techniques suitable for the grade and intended service application.

Corrosion Resistant Plate A588 This specification covers high strength low alloy steel which is made to reduce weight without sacrificing strength and is primarily used in structural applications. Additionally, this grade is more resistant to atmospheric corrosion in most environments than carbon steel and when properly exposed to the atmosphere this steel is suitable for many applications in the bare or unpainted/uncoated condition. Applications A588 steel is intended to be used in structural applications demanding higher strength in a low alloy product for enhance weld ability like bridges. However it is also made to a fine grain standard making it ideal for manufactured goods like tubing. This material performs well in structural applications where corrosion resistance is desired with or without painting or coating the finished product. A prime example again is bridges. In uncoated applications the material will allow surface rust to a point where the corrosion is halted or retarded depending on the corrosive nature of the surrounding atmosphere.

High Brinell or Wear Plates are made from heat treated, high strength, abrasion resisting steels. Analysis Because these plates are made to a specific hardness range rather than to a specific ASTM grade, there is a wide range of chemistries found in these steels depending on the mill of origin. Applications This steel is used in applications requiring high strength and high wear resistance. Good candidates for these steels are mining, earth moving equipment, loader buckets, cutting edges, chutes, slurry pipe, ore bins, and similar uses. Grade Tensile Strength (P.S.I.)

Constructional Alloy A54 Heat treated constructional alloy steels are low-carbon alloy steel with a level of strength substantially higher than that of the highstrength low alloy grades. This higher strength is obtained by heat treating, water quenching and tempering. The alloying elements and amount of the alloy content vary among the grades depending upon the section thickness and desired properties. Their general weldability is improved by the lower carbon content. The range of hardness for ASTM A-54 is Brinell 25-29. This range is sometimes referred to as Regular Quality. If you have specific hardness requirements, please contact our sales office. Plate Products Page 54

It is for welded construction where procedures are suitable to maintain the properties of the plate. 2 and 60 Minimum Brinell Quality are for applications where higher hardness and strength in conjunction with increased resistance to impact abrasion are important. PLATE Forming Regular Quality can be cold-formed readily, provided sufficient power is available and allowance is made for greater spring back than with mild steel. Thickness Of Material Up to " inclusive Over inch to 2" inclusive Minimum Radius Two Times Thickness Three Times Thickness Warm forming may be done at temperatures below 00 o F. without destroying the mechanical properties or toughness. Hot forming may be done at 600-800 o F, but the formed part must be heattreated to restore its original properties. To insure proper safety and the structural integrity of the finished product we will assist you with heat number and source-mill information so that you can obtain accurate information from the producing mill prior to any attempt to form this material.

Machinability The cutting speed of Regular Quality is 65 surface feet per minute or approximately 40% of 22. Weldability Similar techniques to those used in structural carbon steels apply but precautions must be used. Hydrogen must be kept out of the welding operation. Large sections or those under high restraint should be preheated to temperatures not exceeding 400 F. Heat Treating Stress relieving may be performed by heating at temperatures up to 00 o F.

Sheet Products Hot Rolled ASTM-A0 Commercial Quality is suitable for all ordinary purposes where the presence of oxide on the surface is not objectionable. Sheets of this quality may be suitable for bending and moderate forming; however, they are not guaranteed against breakage except that caused by piped steel (material with tubular voids). Commercial Quality sheets should be capable of withstanding standard test bends, i.e., being bent flat on itself in any direction at room temperature. Analysis Carbon Manganese Phosphorus Sulphur.5 Max..0 -.60.04 Max..05 Max. Applications Commercial Quality sheets have good ductility. They are easy to fabricate and are used for a wide variety of purposes, such as barrels and drums, lockers, cabinets, doors, blower and ventilating systems, bins, partitions, chutes, steel jackets, and agricultural equipment. Weldability This quality of sheet presents no welding problems, when using all welding processes. Welding quality is generally extremely high for welds and joints. Welding rod specifications are dependent on welding conditions such as thickness of section, service requirements and design to name a few of the probable welding conditions. Sheet Products Page 62

High Tensile Sheet ASTM A607 Grade 50 High Strength / Low Alloy sheets (sometimes referred to as High Tensile sheets) are rolled and generally stocked in Grade 50.

Mechanical Properties Tensile Strength (P.S.I.) Yield Strength (P.S.I.) Elongation In 2" All Gauges - Gr 50 65,000 Min. 50,000 Min. 22% Min. Forming High Tensile Sheet may be hot or cold formed. To insure proper safety and the structural integrity of the finished product we will assist you with heat number and source-mill information so that you can obtain accurate information from the producing mill prior to any attempt to form this material. SHEET For cold forming, a greater force is required to produce a permanent set because of the higher yield point than carbon steel. It is suggested for cold forming that the inside radius of the bend should be at least equal to the thickness of the material for sheet and strip up to " inclusive; at least twice the thickness of the material over " to ", inclusive; and three times the thickness for material over " to / 2 " inclusive. Page 6 Sheet Products

Punching and Shearing Shearing may require tighter and more secure clamping if a clamp hold down is used because the metal tends to pull more than structural carbon steel. Punching requires up to 20% greater force than for equal thicknesses of ASTM-A569 material. Gas Cutting No special precautions need be taken beyond those required for structural steel, and the heat effects and cutting speeds are similar for both grades. This material can be plasma-cut with minimal warpage. Weldability High Tensile is readily welded by all the usual methods, i.e., shielded metal arc, submerged arc, and electrical resistance, including spot welding. An important advantage in welded structures is the fact that this material experiences an increase in the yield and tensile strength with practically no decrease in elongation when stress-relieved. Cold Rolled Sheet ASTM A008 Specification: Commercial Quality Sheets of this quality should be suitable for bending and moderate forming; however, they are not guaranteed against breakage except that caused by piped steel (material with tubular voids). Sheets of Commercial Quality should be capable of withstanding a standard bend test, i.e., being bent flat on itself in any direction at room temperature. Cold Rolled Sheets are from continuous mill production from low-carbon open-hearth rimmed, texture or capped steel with a carbon maximum of 0.5. Applications The dull surface texture is suitable for paints, lacquers and enamels. Cabinets, appliances, auto body parts, furniture, file cases and desks, partitions, and doors are some applications for cold rolled sheets. Sheet Products Page 64

Flat Galvanized Sheet ASTM-A65 Commercial Quality Flat galvanized sheets are from low-carbon open-hearth steel. They are flat, have closely guarded shearing tolerances, and are ductile and soft. These sheets are produced by passing the base sheets through a bath of molten zinc which, after controlled cooling, gives a clean, bright, uniform spangle. Stamping, cold drawing, double seaming and brake or roll forming will not impair the protective quality of these sheets. Applications Flat galvanized sheets are used as the prime general sheet metal for heating, cooling, joist hangers, and for sign work if the sheets are primed before painting. Paintable Galvanized Sheet ASTM-A65, G40 Paintable Galvanized Sheet, sometimes called Paint Bond or Wiped Galvanized, has a surface coating that makes priming unnecessary. Applications Paintable galvanized sheets are used in applications where paint, enamels and lacquers will be used or where flat, stretcher-leveled sheets are needed. These sheets can be drawn, stamped, formed, and sheared without cracking, peeling or flaking. SHEET Office furniture, cabinets of all types, appliance shells, truck and trailer bodies, lighting fixtures, signs, air conditioning and refrigeration equipment are some applications for Paintable Galvanized sheet.

Expanded Metal Terminology Material Terminology Expanded Metal (also called raised or regular expanded metal) is metal sheet that is simultaneously slit and stretched into a rigid, open mesh. It is available in carbon, stainless and galvanized steel, and in aluminum. Flattened Expanded Metal is made by passing expanded metal through a rolling mill to flatten it. This process reduces the thickness slightly and provides a smooth, flat surface. Expanded Metal Grating is made from thicker sheet or plate, by a process similar to that which produces expanded metal. Expanded metal grating is often used for catwalks and platform applications where self cleaning and good footing are required. Decorative Expanded Metal is manufactured so that the open areas have unique, decorative shapes. Expanded Metal Stair Treads use expanded metal grating for the horizontal surfaces, flat bar for the vertical surfaces and angles at the corners. The Bond is the point where adjacent Strands intersect. The bond is always twice the width of the Strand. C.S.F. (00 Square Feet) is the unit of measure that is used to weigh and price expanded metal. Camber is a slight bow which can occur during manufacturing and results in an out-of-square condition. Deburring is a process whereby most expanded metal is passed through rotary steel brushes to remove burrs and rough edges. Expanded metal grating and very light expanded metal are generally not deburred. The Diamond is the diamond-shaped open area formed by the Strands and bonds (also referred to as the Opening). F.X.M. is the commonly used abbreviation for Flattened Expanded Metal. L.W.D. or L.W.O. refers to the Long Way of the Diamond or Long Way of the Opening. This is used to make it clear that you are measuring in a direction that is parallel to the largest dimension of the diamond. Expanded Metal and Expanded Metal Grating is manufactured with the LWD running the width of the sheet or the length of the sheet. Mesh is the nominal distance, expressed in inches, from the center of one bond to the center of an adjacent bond measured across the S.W.D. The Opening Size is the area enclosed by the Strands and bonds. The Overall Thickness is the finished thickness of the sheet which often determines the selection of framing components. The Percent of Open Area is used by designers to calculate the degree to which light and air can pass through a piece of expanded metal. The Pitch is the measurement from a point on one diamond to the same point on an adjacent diamond. R.X.M. is the commonly used abbreviation for Raised Expanded Metal. S.W.D. or S.W.O. refers to the Short Way of the Diamond or the Short Way of the Opening. This is used to make it clear that you are measuring in a direction that is parallel to the smallest dimension of the diamond. Expanded Metal and Expanded Metal Grating is manufactured with the SWD running the width of the sheet or the length of the sheet. The Strand is the single metal strip that forms the border of the diamond, or opening. The strand has thickness (the thickness of the sheet) and width.

Bar Grating Products Welded Bar Grating is a manufactured product which has a multitude of uses. For instance, it is used to cover trenches in pavement, to make selfcleaning stair treads and to construct platforms around equipment. There are a number of questions that you will need to answer when ordering Welded Bar Grating:. What material? Most Welded Bar Grating is made from carbon steel but it is also available in Stainless Steel and Aluminum. A similar product is made from fiberglass for use in highly corrosive applications. 2. Which way do the bearing bars run? For greatest strength the bearing bars will usually run the short way of the span. (If you had a trench that was 0" X 20" the bearing bars would normally span the 0" dimension of your trench. See the illustration of bearing and cross bars on the next page). What is the size of the area that you need to cover? Give the size in inches and remember to allow for clearance. If you are putting grating into a 0" wide trench, a 0" wide piece of grating will not fit. You would want to order your grating somewhat narrower, say 9 " or 9 7 " in width in order to clear. 4. Are the pieces to be banded? Banding is used to close the spaces between the bearing bars. This makes for a more finished look, keeps the ends from being bent out of shape and reduces the chance of injury from the exposed ends of the bearing bars when the pieces have to be handled. 5. Are the pieces to be painted or galvanized? When special ordering you may specify that the grating be painted or galvanized by the manufacturer. 6. Are the bearing bars to be serrated or smooth? When special ordering you may specify that the top edge of the bearing bars be cut in such a manner that a series of bumps will provide greater friction. Remember that while Welded Bar Grating is available in custom sizes, you will want to work from standard ' X 24' panels whenever possible. (4' wide panels may be special ordered) This means that in the example of a 0" X 20" trench used above it would take pieces 0" by 6" and piece 0" X 2" to cover the trench with bearing bars running the short way of the span. While it might seem easier to cover the area with one piece, you would have to run the bearing bars the 0' way to cover the trench with one piece. The 0' span would be very weak. Remember also, that you may occasionally have to remove the grating to clean your trench and one man can handle three-foot long pieces more easily than he can handle a ten foot long piece.

Expensive straightening operations are eliminated. Wearability Although easily machined, wear resistant properties are unusually high. Many heat treated or carburized parts have been successfully replaced by unhardened Stressproof in spite of its relative softness. Reduced Costs By eliminating hardening and straightening operations, reducing machining time, lowering steel costs when replacing alloy steels, and by improving the quality of the finished part, STRESSPROOF will give you reductions in costs on many parts. While the price is slightly higher than ordinary carbon bars, its increased strength, wearability and service life make it the most economical steel to use in many applications. Precision C-045 Shafting Precision Shafting represents the highest degree of straightness, accuracy, concentricity and surface perfection obtainable in commercial practice. These bars are turned and centerless ground to close limits over their entire length, and burnished to a high finish after grinding. It is important to note that turning does not alter the physical properties of the bar. COLD FINISHED BARS Page 8 Cold Finished Bar Products

Analysis Specification Carbon Manganese Phosphorus Sulphur C-045.4 -.50.60 -.90.04 Max.05 Max. Application This steel is often called pump rod or pump shafting due to its high degree of straightness (important in high speed shafting). The special straightness serves to prevent vibrations and wear on packings and bearings which must be avoided in deep well pump work. Other uses include motor shafts and other applications where high speed work necessitates straightness and accuracy along with the ability to be machined unsymmetrically with practically no danger of warpage.
