Quick Details Product name:galvanized steel coil DX52D Key Word:Steel Coil Certification:ISO9001:2008 Keyword:High Strength Galvanized Steel Coil Coil ID:508/610mm Width:600-1500mm Length:Requirement galvanized steel coil Zinc 30鈥?75g/m2 grades of price Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet. Sacrificial, or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. GALVANIZED STEEL COIL Standard Grade Zinc coating Width Thickness Length JIS G3302SGSGCH/SGCC.SGCH.SGH340Z40g/m2-600g/m2600mm-1500mm0.14mm-5.0mmcoil EN 10346DX51D+Z/DX53D+Z/S220GD.S550GDZ40g/m2-600g/m2600mm-1500mm0.14mm-5.0mmcoil ASTM A 653CS-B/S S255-550Z40g/m2-600g/m2600mm-1500mm0.14mm-5.0mmcoil Package: Standard seaworthy export packing, other types of packing can be customized as every requirement. 1) 4 eye bands and 4 circumferential bands in steel 2) Galvanized metal fluted rings on inner and outer edges 3) Galvanized metal & waterproof paper wall protection disk 4) Galvanized metal & waterproof paper around circumference Delivery: Within 5 - 20 work daysGalvanized Steel Coil factory website:http://www.sdcrsteel.com/galvanized-steel-coil/
