Sand blasting and shop primer for JIS G 3101 SS400 steel plate

 

China is a large supplier of JIS G 3101 SS400 steel plates. Every day, tens of tons of SS400 steel plates are delivered to ports and exported. It is easy to find that most SS400 steel plates are equipped with sandblasting and shop primers. What is the function of JIS G 3101 SS400 steel blasting and shop primer?

It is not difficult to understand that the primer has the effect of protecting JIS G 3101 SS400 steel plates from rusting during sea transport. The thickness of the primer is usually around 20 microns. Sandblasting gives a certain roughness to the surface of JIS G 3101 SS400 steel sheet, thereby improving the adhesion of the paint film or shop primer.

Therefore, for JIS G 3101 SS400 steel plates that require transportation for a period of time, both customers and suppliers tend to perform blasting and shop primers.
