Sandblasted stainless steel
1. Core features
① Surface morphology
Uniform rough surface: The surface Sa value is 2.5-5.0μm, presenting a fine granular texture
Completely non-reflective: Light absorption rate > 95%, achieving a true matte effect
Three-dimensional anchor pattern structure: Forms microscopic concave and convex, enhancing the adhesion of the coating (up to 5B grade)
② Performance advantages
Super strong defect concealment ability (can cover 0.3mm deep scratches)
Outstanding anti-slip performance (static friction coefficient 0.6-0.8)
Excellent coating substrate (adhesion increased by 300% compared to polished surface)
