AZ Coil Bobina De Chapa Galvalume DX51D AZ150 With 0.35mm 0.43mm And More Sizes

Short Description:

Bobina De Galvalume is Zn-Al alloy coated, and the coating composition is 55% Al, 43.3% Zn, and 1.6% Si. Because of its excellent corrosion resistance, this kind of steel is gradually replacing galvanized steel and is widely used all over the world.Its atmospheric corrosion resistance is 2-6 times higher than that of the hot-dip galvanized sheet with the same coating thickness. The price ofzincalume coil is higher than that of ordinary hot-dip galvanized steel coil, but because the specific gravity of aluminum is smaller than zinc, the specific gravity of aluminum-zinc alloy coating is only 3.75kg/dm3, while the specific gravity of zinc is 7.1kg/dm3, so the coating weight of the aluzinc galvalume metal coil 150g/m2 (double-sided) is the same as that of the hot-dip galvanized steel coil with the coating weight of 275g/m2 (double-sided), which greatly saves the cost.

Product Advantages
1.Available for customized specification on customers' request.
2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.
4.Perfect Light Refelectivity. The ability of reflecting light and heat is twice that of galvanizing.
5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.

 Galvalume Coil Application 
The galvalume steel coil has both the characteristics of hot-dip galvanized steel sheet and hot-dip aluminum steel sheet. Therefore, where hot-dip galvanized steel sheet is used, galvalume steel coil can be used, and it can also partially replace hot-dip aluminum steel sheet. It has a wide range of applications, such as roof panels, wall panels, light steel keels, heating radiators, car bodies, fuel tanks, cable armored steel tapes, plastic greenhouses, granaries, shipping containers, household appliances and appliances, Ovens, explosion-proof steel belts, outer covers of air conditioning and ventilation systems, solar water heaters, packaging boxes for chemical products, and color plate substrates, welded pipes, steel windows, cold-formed steel materials in the metallurgical industry, etc., have a very broad application prospect.
