Surface Profile Gauges

We have three gauges that fall into this category. The DeFelsko Surface Profile Gauge and also the Replica Tape Readers. You can click on either image to take you to the relevant page.

Why Is Surface Profile Measurement Important?

Steel is often abrasive blast cleaned or otherwise roughened prior to painting. The peak-to-valley height of the resultant surface profile is an important factor in the performance of applied protective coatings. Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely.

The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.
