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 steel strip is widely used for construction, steel frame, structure.
The surface of the galvalume strip has a unique smooth, flat and gorgeous star flower, and the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the galvalume coil can reach 25 years, the heat resistance is very good, and it can be used in a high temperature environment of 315 ° C; the adhesion between the coating and the paint film is good, and it has good processing performance, which can be punched, sheared, welded, etc. ; good surface conductivity.
With the development of various industries in the national economy, the market demand for galvalume/aluzinc products is increasing due to their excellent performance, and the market scale of the galvalume industry is also increasing.
