Product Introduction

TQC roughness comparison block

TQCSheen provides roughness comparison blocks (LD2040 Grit, LD2050 Shot) for sandblasting rust removal to achieve roughness grading close to white level (Sa2.5 and Sa3). The peak values of the cross-sectional profiles of the four standard rough surfaces are 25, 60, 100, and 150 μ m. Compliant with ASTM4417 and ISO8503-2 standards, with fine grades ranging from one to two pieces, medium grades ranging from two to three pieces, and coarse grades between three and four pieces.
