1 Architectural Roofing & Wall Systems

2 Welcome to MetFab MetFab is a leading architectural metal fabrication expert. Our talented craftsmen produce a wide variety of factory formed and field fabricated profiles that provide architects, designers, and engineers new and better ways to bridge old problems with roofing, siding, and architectural detailing. MetFab roofing systems, wall panel systems, cornices and column covers are all designed with innovative locking systems that make field fabrication and installation easier than ever. Although, it s our manufactured to order capabilities that make MetFab one of the most unique manufacturers in the industry, MetFab prides itself on the ability to create, match, and/or design systems to meet the building owner s specific demands. Our color palette includes both old favorites and new ones, appealing to a wider, more diverse segment of the architectural/design community for both the commercial and residential markets. Our MetFab color finishes are among the best and most durable resin formulas on the market today, with superior resistance to chalking, erosion, and industrial pollutants. These paint systems are produced with reflective pigments to reduce cooling costs and heat island affect. In addition, property owners and designers should be pleased to know that many of our products are sourced locally, utilize environmentally sustainable qualities, and are recyclable. MetFab is, and continues to be, a company that values its artisan skills and working one on one with architects to meet the most exacting demands of modern structures and the specific requirements of historical restorations.

21 MetShield Underlayment High Temperature Waterproof Underlayment Membrane MetShield Water and Ice protection is a sheet membrane underlayment specifically designed for high temperature application typically found under metal roof installation. MetShield is a 40 mil SBS modified bitumen with a UV resistant anti-slip polyethylene woven top facer, which will prevent water penetration from wind driven rain and water back up caused by ice or debris back up. Met- Shield is used specifically as a metal roof underlayment and is required under all warranted systems. Features and Benefits: High Temperature Formulation: MetShield will resist temperatures up to 250 F without degradation of the adhesive. Moisture and Air Barrier: MetShield protects the roof structure from water seepage caused by ice dams and wind driven rains. Self Sealing: MetShield membranes seal around roofing nails, screws and clips used to install the primary roofing system. Dual Barrier Protection: Dual Barrier Protection MetShield provides maximum water-proofing protection. The composite membrane consists of a SBS modified bitumen with a UV resistant anti-slip polyethylene woven top facer.

22 Metal, Finishes and Considerations Finishes. The resin system in MetFab high performance finish Fluropon is made up of 70% Kynar 500 or Hylar 5000 resin. The carbon/fluorine bond, which gives Kynar 500 or Hylar 5000 resin based coatings their stubborn resistance to chalking and erosion as well as their resistance to harsh airborne industrial and atmospheric pollutants, is one of the strongest chemical bonds known to man. The standard coating thickness of 1.0 mil will provide a lifetime of service. Additional coatings can be applied to meet ASTM specification D 968, for falling sand of 100 or 230 liters. If desired, metallic, custom colors, high gloss, low gloss and Duranar XL systems can be produced. Contact manufacturer for pricing. MetFab paint finishes include: Trinar (Fluoropolymer) MetFab Metals standard colors are produced by Akzo Nobel and contain a minimum of 70% PVDF base resin with ceramic pigments. All colors are formulated to ensure consistent appearance and quality. The Trinar system is applied over Akzo Nobel polyester primer in a minimum thickness of 0.2 mil and can be applied to either Galvalume HD Galvanized or Aluminum substrates. All topcoats are minimum of 0.8 mil of the Trinar color choice. The reverse side is primer and a washcoat of 0.5 mil total dry film thickness. Drexlume MetFab offers a mil finished Galvalume with a two-sided, clear acrylic finish that simultaneously aids roll forming without the use of lubricants and eliminates unsightly handprints or stains resulting from handling and storage. The acrylic finish dissolves naturally over a period of time, and when left as it is, allows for natural and even weathering. Material. Aluminum is produced to meet ASTM B 209 and is offered in 3105, 3003, or 5005 alloys. Galvanized steel is produced to ASTM standard A 653M and has a yield strength of 37 KSI and a tensile of 52 KSI. Galvalume is produced to meet ASTM A 792. These products are tension leveled to produce the flattest product possible. Oil canning is an inherent trait of thin gauge metals. Stucco embossing may be utilized to help eliminate some of the visual appearance of oil canning. Copper, stainless steel, and terne coated stainless are also available. Please contact manufacturer for more information. Accessories. All MetFab trims, clips, and custom formed products are produced with CNC accuracy. This ensures that the lengths, angles, and dimensions are produced to exact specification. If you choose to fabricate your own trims, a full line of flat sheets are in stock. A flat sheet size of 48" x 120" with vinyl protection is standard. A wide range of clips are stocked to ensure proper attachment for your specific requirements. Field Fabrication. MetFab is one of the few manufacturers capable of providing both factory and field fabrication of its complete line of products. Field fabrication will produce a quality product as good or better than one manufactured in the plant. When panel lengths exceed 50', the chances of damage during shipping and rooftop staging are great. Site fabrication eliminates product damage, shortages, and excess waste. All panels can be cut to exact field conditions and do not require extensive crating. Site fabrication will also allow for precise sizing of rake panels which ensures a watertight condition. Most importantly, site fabrication eliminates all end laps, the number one cause of metal roof leaks. MetFab recommends, where possible, that no end laps occur. With field fabrication, panel lengths up to 200' are possible. Warranty. High performance metal roofing products are available in Galvalume and Aluminum. All metal products are tension leveled for superior flatness. 35 year non pro-rated PVDF paint warranty with a 20-year Galvalume Substrate Warranty 35-year non pro-rated PVDF paint and 25-year Aluminum Substrate Warranty 20-year non pro-rated International PVDF Paint Warranty 25-year non pro-rated Drexlume TM (Acrylic Coated Galvalume ) Warranty Testing and Ratings. Many MetFab products are rated for water and air infiltration. Load spans and UL-90 certifications can be verified by registered engineers. System assemblies and construction details vary and not all assemblies have been tested. Please contact our technical staff to answer your specific questions. Considerations. MetFab Cap Seam and Snap-On Batten panels must be installed with a minimum of 3/12 slope over solid substrate with MetFab underlayment. MetFab Snap-On 675, Snap-On 550, and Snap-On 400 panels are limited to 3/12 slope, but can be installed over open framing. For lower slope applications, the Historic and MetFab III are the choice. Panels longer than 30' need to utilize sliding or non-restricting clips. Contact our technical department for proper clip spacing. The use of MetShield, a self-adhering, rubberized asphalt sheet membrane, will allow for a watertight installation, particularly in low slope and curved applications. MetShield should also be considered where ice and water backup can occur, such as eaves and valleys. When installing MetFab products and accessories, refer to the SMACNA architectural manual to ensure good sheet metal and roofing practices. Oil Canning. MetFab utilizes top quality materials specifically designed for rollforming applications. Oil canning is naturally inherent in sheet metal, appearing as waviness in the flat portions of the sheet. All MetFab products are tension leveled to help minimize excessive oil canning. Oil canning is not grounds for rejection. There are a few ways to help minimize this appearance, such as specifying narrower panels, utilizing stiffener ribs or striations, and/or specifying stucco embossed material. 22
