Steel Surface Roughness Comparator
Comparison Plates for Assessing the Roughness of Grit-Blasted Steel Surfaces
Steel Surface Roughness Comparator is a professional surface inspection tool developed for the fast and reliable evaluation of the roughness level of blasted steel surfaces. It is used to verify the suitability of the surface profile before paint and coating applications.
Manufactured from high-quality steel, the comparator plates contain reference profiles in accordance with ISO 8503 standards and help determine whether the blasted surface profile is fine, medium, or coarse.
The surface profile created after blasting is critical for paint and coating performance. Insufficient or excessive surface roughness can negatively affect coating adhesion and long-term durability.
Steel surface roughness comparator plate enables quick quality control by allowing visual and tactile comparison of the surface profile with reference profiles.
It can be used in accordance with ASTM D4417 Method A, TS EN ISO 8503-1, and ISO 8503-2 standards. This ensures reliable and comparable results during surface preparation processes before painting.
