Service
ATA sandblasted stainless steel Service
Sandblasted stainless steel is a high-precision surface treatment process that uses abrasive particles (such as aluminum oxide, silicon carbide) sprayed at high pressure to create a uniform matte surface, combining functional durability with industrial aesthetics.
The process is completed by adjusting abrasive particle size, spray pressure and distance, performing automatic or semi-automatic sandblasting operations, and conducting post-treatment to ensure a consistent, dust-free and corrosion-resistant surface.
ATA provides one-stop sandblasted stainless steel services, covering material analysis, abrasive selection, precision sandblasting, post-treatment inspection and packaging, to meet customized industrial surface finishing needs of different industries.
