Color coated steel coil coating adhesion is an important technical indicator to evaluate the quality. At present, T-bend test is used to characterize the adhesion of color coated steel coil coating in domestic and overseas. However, the part of color coated…
In theory, the color coated steel coil clean needs to be done once every six months. And in the coastal with many salt frog and industrial dust heavier places, cleaning should be more frequent. Generally the clean water is OK. But…
1. The edge of dripping eave. With the influence of rainwater and moisture condensation, the most serious corrosion is the edge of dripping eave. The initial sign of incision corrosion is the tiny bubbles that are visible to the underside…
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…
The mechanical property and coating property can impact the color coated steel processing and forming process. CAMELSTEEL have concluded three notices previously. Here we will keep introducing some other notices. 1. The cutting section during color coated steel processing is…
Due to the coatings on the surfaces of color coated steel sheets, it’s very different with the common rolled sheets. For the mechanical property and coating performance which has a big influence on color coated steel sheets, the technicists in…
