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…
The process requirements of hot-dip galvalume steel sheet during production id higher than galvanized steel, below are its main performance: 1. The hot-dip galvalume steel sheet has high melting temperature. And it also has high requirements to the fluctuations of plating…
A. Reasons 1. The wettability of Al-Zn-Si melt and steel is much worse than pure Zn melt. At the same time, as the drastically increase of plating bath temperature and the aluminum content, the manufacturing technique of hot dip galvalume…
There are snow-like spangles on the surface of galvalume sheet metal. And according to the different of steel mill, the spangle size and uniformity will have some difference. With the thickening of the galvalume sheet metal, the size of the spangle…
