Color steel plate characteristics and installation Characteristics of color steel plate A.) The color steel plates can be disassembled and then restored, which can be easily assembled and disassembled. The standard unit wall panels can be interchanged, which is very…
History of Prepainted Steel Sheet The production of prepainted steel sheet originated in the United States in the mid-1930s. In the beginning, the technology was only adopted in producing a prepainted steel strip. Till 1995, the first batch of coating…
Galvanized layers and galvalume layers have their own advantages and disadvantages. 55% Al-Zn-Si plated layer not only sum up the advantages of both, but also overcome their shortcomings. This is because of its special structure of the cladding material. Hot…
The chemical composition of galvalume layer in hot-dip galvalume steel products isn’t a specific point or area on phase diagram. It’s a composition with better performance chose according to the need. 1. The choice of aluminum content Aluminum content of aluminum products is…
Hot dipped galvalume steel sheet is in aluminum zinc alloy structure. And hot dipped galvalume steel sheet is composed of 55% aluminum, 43.4% zinc and 1.6% silicon to solidify at 600 ℃ high temperature. The entire structure is a kind of…
On the basis of the two steel corrosion control method of hot dip galvanized steel sheet and hot-dipped galvalume steel sheet, galvalume steel sheet is developed based on their advantages. The cladding material of hot-dipped galvalume steel sheet has a…
Due to the process characteristics of aluzinc steel coil, it is prone to ouccr some defects. In addition to the surface coating is loose, the aluzinc steel coil is also prone to occur the following defects: 1. Skip plating. Due to…
White coating is the result of the intense reaction between aluminum zinc liquid and the iron on the steel sheet. If the process parameters appear deviated, the galvalume steel coil will be white, or even occur rough coating. And galvalume steel coil…
Large amount of slag production during the galvalume steel sheet process is a very troublesome thing. It will not only increase the workload of slag, but also to product quality has a great impact. To reduce the number of slag…
