JINAN JUNDA STEEL SHOT BLASTING

The preparation of the steel surface using the steel shot blasting system is totally safe and environmentally friendly. The standard used is SA 2.5 with a roughness of 60 to 70 µm or SA 3.0 standard, which consists of removing all scaling scale, rust, foreign matter incrustations, etc. The blasted surface has a light gray color, which is the original color of the steel, and leaves the material with a certain roughness to have the necessary adhesion for a quality painting.
