Description
Portable Surface Finish Gauge for Grit & Shot Blasted Steel
Brought to you by TQC Sheen, our paint testing specialist brand, this durable surface roughness comparator is designed for estimating the surface profile of grit or shot-blasted steel. Fully compliant with ISO 8503-01, it enables standardized comparison of blasted steel substrates prior to protective coating.
Easy-to-Use Surface Comparator for Lab or Field
Housed in a protective leather pouch, the portable gauge offers side-by-side visual and tactile comparison of blast-cleaned steel surfaces. Profiles are graded as Fine, Medium, or Coarse. Simply match the test surface against the comparator segments to determine surface roughness grade.
Why Surface Roughness Matters
Surface texture affects paint adhesion, coating durability, and corrosion resistance. Measuring roughness helps identify proper blasting procedures and coating compatibility in industries such as shipbuilding, infrastructure, and industrial painting.
