Regarding the price, the color steel plate has something to say！ Hello everyone, I am a color steel plate. Although I’m everywhere around everyone, But there are still many people who don’t know me well. People often come up and…
Galvanized metal rolls Steel Coils have coated by zinc are used in the manufacture of roofing and facade materials. Galvanized steel coils acquired when high resistance to corrosion in any climatic conditions is needed: The production of components for facades,…
The choice of PPGL steel sheet in different area mainly consider about the local snow load and corrosive environment. But quantitative description of the corrosion environment of a region is relatively difficult. There are many corrosion factors that influence the PPGL steel sheet. Such…
Galvanized steel coil is kind of thin steel plate. It coated with a layer of metal plate on the surface to prevent surface corrosion of steel plate and extend its service life. Its produce process includes uncoil, weld, clean, smooth and…
For different color coated steel coil use environment, using different types color coated steel coil can have more effective prevention to achieve a certain number of service time. For example, the ordinary environment generally use ordinary PE polyester color coated steel…
The difference in the protective atmosphere is mainly manifested in the difference in hydrogen content. Galvanized hydrogen content is generally controlled at 15-30%, while the hydrogen content of galvalume is generally controlled at 25-50%. The controlled temperature when entered the…
1. There are some problems during the process of surface cleaning. The hot dipped galvanized steel coils substrates are not cleaned well and cause internal oxidation. 2. After coming out of the zinc pot, the zinc layer thickness of the hot…
There are 3 stages of color coated steel coils coatings’ quality control. The controlling unit before coating decides all of the coatings, which CAMELSTEEL has introduced before. Now, here will introduce the work process control and failure mode severity control…
The quality control of coating of prepainted coils is conducted in three phases. Namely control before coating, control during construction of coating and control on failure degree after coating. Technicians in CAMELSTEEL hold that control before and during the construction…
The galvanization on the gi steel sheet surfaces makes the steel have a great corrosion resistance. Then the service life is very long. Therefore, it is widely used into many industries. But during the gi steel sheet production process, it maybe…
