4 SINGLE BEAMS STANDARD HOLE DRILLING Universal Beams (UB) and Universal Columns (UC) Standard spacing for holes drilled into Web Standard spacing for staggered Holes drilled in top or bottom Flange Single Beams

5 SINGLE BEAMS Single Beam CONNECTIONS Universal Beams (UB) and Universal Columns (UC) Cleat Connection - The angle cleat connection comprises angle cleats on one or both sides of the web of the supported member. Each cleat is bolted to both the supported and the support members. Cleats are made from RSA sections (angles) Hold down Bolts End Plate Connection - The end plate connection comprises of a Flat plate, the plate is welded to the supporting member then bolted to the support member. Single Beams Single Beams

6 PARALLEL FLANGE CHANNELS STANDARD HOLE DRILLING Two Channels Bolted Back to Back. Bolts are typically 600 mm apart from each other. This structural connection comes complete with Grade 8.8 bolts Two Channels Bolted Back to Back with Spacers. When a cavity wall needs to be supported above an opening, two PFC s can be bolted together back to back, with a spacer in-between, in order to give strength to the walls. The gap between the sections matches the width of the cavity, and the spacing between the bolts is typically 600 mm centre to centre Two Channels Bolted Back to Back with Channel Spacers. The bolts are typically 600 mm apart from each other. Parallel Flange CHANNELS

7 PARALLEL FLANGE CHANNELS CHANNEL CONNECTIONS Cleat Connection - The angle cleat connection comprises angle cleats on one or both sides of the web of the supported member. Each cleat is bolted to both the supported and the support members. Cleats are made from RSA sections (angles) End Plate Connection - The end plate connection comprises of a Flat plate, the plate is welded to the supporting member then bolted to the support member. Hold down Bolts Parallel Flange CHANNELS

8 DOUBLE BEAMS STANDARD HOLE DRILLING Universal Beams (UB) and Universal Columns (UC) When projects are struggling for height, for instance in basements and lofts; it is often preferable to replace a deep beam with two smaller beams. However, to ensure stability and resistance to buckling, these beams need to be bolted together, and this is where a spacer is used. The bolts are typically 600 mm apart from each other. Double Beams bolted together with Spacers Double Beams bolted together with Channel Spacers Double BEAMS Double BEAMS

9 DOUBLE BEAMS Double Beam CONNECTIONS Universal Beams (UB) and Universal Columns (UC) Cleat Connection - The angle cleat connection comprises angle cleats on one or both sides of the web of the supported member. Each cleat is bolted to both the supported and the support members. Hold down Bolts Double BEAMS

10 TEE BEAMS Two universal beams (UB's) or universal columns (UC's) Channels (PFC) or a combination of the two, joined together at 90 degrees with angle cleats or an end plate connection. This structural connection comes complete with Grade 8.8 bolts Cleat Connection - The angle cleat connection comprises angle cleats on one or both sides of the web of the supported member. Each cleat is bolted to both the supported and the support members. Cleats are made from RSA sections (angles), which are then bolted to both beams End Plate Connection - The end plate connection comprises of a Flat plate, the plate is welded to the supporting member then bolted to the support member.

11 FLITCH PLATES Note: Timber is not supplied Flitch Beam is made up of Steel Flat Plate sandwiched between two timber beams. The three layers are then held together with bolts. Flitch Plate with horizontal drilled holes Flitch Plate with Staggered drilled holes Flitch Steel FABRICATION PLATES Flitch PLATES

12 SPLICED BEAMS Splices are required when a beam is either too long or too heavy to install safely. When a beam spans two party walls, a splice is also recommended to easily install the beam. As a rule of thumb, the flange plates need to be at least the same thickness as the beam s flange, and the same rule applies to the web plates. Spliced Beam with Flange plate and Web plate connections Spliced Beam with an End plate connection. When height is limited, an end plate Splice may be required. Spliced BEAMS

13 PLATES PLATES Flat Plate can be welded or bolted to Universal Beams (UB), Universal columns (UC) and Parallel Flange Channels (PFC) The plate is added to the Beam to support brickwork or timber joists. The plate is often offset to one side so the brickwork is sufficiently supported. A top plate can be added to a beam when the size of the required beam is smaller than the wall it is carrying. Plate flush with one side of Beam To top flange To bottom flange

14 PLATES PLATES PLATES Plate centered on Beam To top flange To bottom flange Plate Of-centered To bottom flange To top flange

15 CRANKED BEAMS Cranked beams are most frequently used to support roof structures; therefore the angle of the middle member needs to follow the pitch of the roof. Full penetration welds are used with these connections to ensure the crank will carry the load. Cranked beams are also commonly used to support staircases. Cranked BEAMS Cranked BEAMS

16 BOX FRAME / PICTURE FRAME A Box Frame of Picture Frame comprises of four universal beams (UB's), universal columns (UC's), box section or any combination of the three, joined together with welded plate and bolted connections. Wall fixing restraints can be added to the posts if specified. All structural connections come complete with Grade 8.8 bolts. Box /Picture FRAME

17 GOAL POST FRAME A goalpost comprises two columns and a top beam, creating a goal shaped structure. Three universal beams (UB's), universal columns (UC's), box section or any combination of the three, joined together with welded plate and bolted connections. Wall fixing restraints can be added to the posts if specified. All structural connections (steel to steel) come complete with Grade 8.8 bolts. Goal Post FRAME

18 STEEL SECTIONS DEFINITIONS Universal Beam (UB) Universal Beams are sometimes described as an I shaped beam or an H shaped beam. Universal Beams are always higher than their width. The 1st dimension is the height of the beam, the 2 nd dimensions is the width of the beam and the 3rd dimension is the weight in kilograms per metre. We stock all the popular sizes in Self-Colour as well as Primer-painted. All sizes can be cut to Length and a Painting, Drilling and Galvanizing service is also available. Universal Columns are sometimes described as I shaped beam or as an H shaped beam. Unlike a universal beam, the UC s width is roughly equal to their depth. Universal columns are mainly used for columns, however their small depth compared to universal beams make them ideal load bearing members when height is limited (which is quite often the case in residential projects). We stock all the popular sizes in Self- Colour as well as Primer-painted. All sizes can be cut to Length and a Painting, Drilling and Galvanizing service is also available. Parallel Flange Channel (PFC) Universal Column (UC) Parallel flange channel is sometimes referred to as C-section. The PFC is used for columns, lintels above doors or simply a beam supporting floor joists. When used for lintels, they have a bottom plate welded to it that takes the outer bricks or 2 channels are bolted back to back with spacers to support both leafs of a cavity wall. We stock all the popular sizes in Self-Colour as well as Primer-painted. All sizes can be cut to Length and a Painting, Drilling and Galvanizing service is also available.

19 STEEL SECTIONS DEFINITIONS Equal Angle (EA) & Unequal Angle (UEA) Rolled steel angle - equal is also referred to as: angle, equal angle or L-shape as well as Unequal Angle. For structural steel purposes, equal angles are most often used for brackets for cleat connections. We stock all the popular sizes in Self-Colour as well as Primer-painted. All sizes can be cut to Length and a Painting, Drilling and Galvanizing service is also available. Mild Steel Flat Plate is used for base plates, end plates, stiffeners, gussets, tabs, splice plates and many more. In some cases they add strength to a beam when welded along the length of a beam. We have a wide range Mild Steel Flat Plate in stock that can be cut to your own specific requirement. Flat Plate Square Hollow Section (SHS) & Rectangular (RHS) Reinforcing Bar (ReBar) A rebar (short for reinforcing bar), also known as reinforcing steel, reinforcement steel, rerod, a deformed bar, reo, or reo bar, is a common bar, and is commonly used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression. Rebar is given ridges for better mechanical anchoring into the concrete We have a wide range of Square Hollow Section SHS and Rectangular Hollow Section RHS in stock that can be cut to your own specific requirement.
