Coupon surfaces are blasted with fine glass beads to remove mill scale. This typically results in a finely textured surface with a typical surface roughness of approximately 50 µIn RA on steel coupons*. Glass beading should remove any mill scale and surface corrosion, but it may not remove all surface defects such as scratches. While not perfect, glass beaded coupons have a much better surface compared to a mill finish and provide more consistent surfaces. The glass beaded surface finish is very economical and is our most popular surface finish.
