To avoid quality problems (such as white rust, black spots, scratches, deformation, etc.) of galvanized coils during storage and transportation, stric

SPCC steel is a cold-rolled carbon steel sheet or strip for general uses, which is named by Japanese Industrial Standard (JIS)

Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance.

Whether the galvanized steel pipe needs to be re-galvanized depends mainly on the degree of damage to the surface zinc coating, the state of corrosion

The service life of galvanized steel pipes is affected by multiple factors such as the use environment, coating quality, and maintenance methods, and

Zinc phosphating is one of the most widely used processes in the pre-treatment of galvanized sheet coating. Its advantages and disadvantages are close

The phosphating process of galvanized sheet needs to be selected based on the characteristics of the substrate (surface state of the zinc layer), subs

Phosphating of galvanized sheet is a key pre-treatment process before painting. Its core function is to form a uniform and dense phosphate conversion

The hardness of galvanized coil is closely related to the strength of the substrate (yield strength, tensile strength). The two are not only fundament
