EMCO Building Products steel siding and accessory products are produced in a wide range of colors and are manufactured for residential, new construction and commercial exteriors or as replacement siding for existing residential and commercial buildings. With steel siding from EMCO Building Products you get the strength of steel and the durability of our exclusive EMCO coatings. Because of their toughness and UV, chemical and heat resistance, it is guaranteed not to rust, crack, blister, chip, peel, flake, or fade.
Steel siding, roofing, and accessories are made from 28-gauge galvanized lock form quality coated steel complying with ASTM 653. Material is designed for markets requiring roll-form ability and as a result, the steel substrate is a low carbon alloy designed to take a 2T bend radius. Chemical and mechanical properties of the steel are detailed in addendum I. The ASTM standards have been approved for use by government agencies. 26-gauge is available for siding and roofing panels in limited colors.
A. Siding panels will contain weep hole spaces approximately every 12 3/4" in the leg of the panel bottom to allow condensation and water vapor to be released from the wall. Nailing hem of the panel shall be approximately 3/4" and contain nailing holes uniformly spaced approximately 1/8" from edge and approximately 1 1/4" on center to provide for expansion and contraction of siding wall or roof.
B. The coating applied to the substrate shall be a roll-coated paint system designed for use with roll-form machinery. Specific data regarding weatherability and other performance specifications are detailed below.
C. EMCO Building Products uses domestic steel sources using a minimum of 70% recycled steel.
The Koolnar™ PVDF coil coating system manufactured and distributed globally by Continental Coatings Inc. and Yung Chi Paint and Varnish Manufacturing Company Ltd., is a Premium 70% PVDF coil coating system engineered for monumental building product applications and severe exterior environments that require long life and extended warranty coverage. The Koolnar™ system uses licensed Kynar® and Hylar® PVDF Fluoropolymer technology which is ultra-resistant to UV radiation and natural weathering. Koolnar™ uses only the highest-quality, long-lasting ceramic and metallic pigmentation to ensure optimal exterior color fastness and longevity. This system is also available in multiple coats and various specialty high-build systems. Koolnar™ may be applied over the Universal PU-11 High Molecular Weight Urethane Primer or PU-30 High-Build Urethane Primer Systems for extreme environment and extra-long service life warranted building product applications.
The Koolnar™ system is designed for trouble-free coil coating line application and has been run for well over two decades on new and old coil lines around the world. Standard topcoat DFT is .70-.80 mils, which allows for optimal application consistency, color stability, and exterior performance. Koolnar™ was formulated to provide improved stain resistance and cleanability, as well as scratch resistance and surface toughness. Superior primer corrosion resistance and substrate adhesion, along with chemically enhanced topcoat intercoat adhesion, greatly minimize field scratch and wet stack storage complaints and handling, transporting, and storage-related claims.
The Koolnar™ system can be formulated in standard and medium, as well as low gloss/low sheen finishes and supplied in limited colors. This premium coating supports an extended warranty and can be applied to a variety of adequately cleaned and treated metal substrates including: Hot Dipped Galvanized, ZnAl, Galfan®, ZAM®, Aluminum, and Stainless Steels. Koolnar™ is formulated with IR Reflective COOL ROOF ceramic pigment technology and can be designed to meet and exceed ENERGY STAR® requirements. It is ideal for high-end, construction-related products like composite panels, high UV exposure roofing, and acidic/alkaline corrosive environments like industrial manufacturing facilities and power plants.
