When welding recommendations are followed, the mechanical properties of welded joints are equal to those of non-coated steels. By continuing to use this website you are agreeing to our, Minimum total coating mass, both surfaces (g/m, Guidance value for coating thickness per surface, typically (μm). The successful forming of metal coated steels depends on selections made regarding the geometry of component, steel grade, metal coating type and thickness, surface quality and protection, and a tool used in the forming. The corrosion resistance provided by the zinc coating is in direct proportion to the coating's thickness. For G90, this is 0.32 oz/ft2. ( * Denotes a required field). �20�9i �+�d�gqch`����HA���-�����օ�����X�0��|;��`�c9S3��L���X�������2�����;HX���P���� All zinc-based coatings are well suited for adhesive bonding provided that the surface is matched with the adhesive (epoxy, acrylic or polyurethane adhesive) used.

Galvanize and GalvalumeTM steel should not be combined on the same building elevation because Galvanize will likely exhibit corrosion before Galvalume. Because of the sacrificial nature of the zinc, the coating provides corrosion protection for areas of exposed steel surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.). For further details on coating specifications, refer to ASTM … Q. 0000002032 00000 n INTRODUCTION: GALVANISED STEEL IRON COIL AND SHEET Galvanized sheet or coil is a process by which zinc, a non-corrosive metal, is coated over corrosive metals, such as iron and steel. One advantage of adhesive bonding is that it preserves the anticorrosion properties of the coating because the coating basically remains intact in the joint area. Metal coated steels can be welded by various welding techniques including different methods of resistance welding, laser welding and arc welding. CRA clad pipe or lined steel pipes for oil and gas industry. G90 Coating contributes about 1.6 mils (0.0016 inches) of thickness to the final coated sheet (or 0.0008 inches of zinc to each side of the material).

To convert from oz/ft2to g/m2, multiply by 305.15 Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2) Since what we are most interested in is the coating thickness, why don’t the ASTM standards use thickness measurements? 3.2.5 regular spangle, n—the finish produced on hot-dip zinc-coated steel sheet in which there is a visible multifaceted zinc crystal structure. This specification is for hot-dip galvanizing steel sheet using the continuous (high-speed) galvanizing process. Note: since the density of the 55% Al -Zn coating is much lower than for the galvanize coating, coatings with the same thickness (20 µm) are much lighter for 55% Al-Zn (150 g/m2))than for galvanize (275 g/m2. Full corrosion protection is also achieved in areas that have been heavily formed because the peeling tendency of low-friction and tightly bonded coating is low. Cordeck offers four popular Form Deck products, providing a wide variety of spanning and loading capabilities.
