Steel doesn’t fail overnight. A pinhole in a tank lining spreads, a hairline crack in a girder blooms with rust, and before long you are budgeting for unscheduled downtime instead of production. Globally, corrosion already drains about $2.5 trillion from the economy each year, and the fastest payback isn’t a thicker coating—it’s knowing exactly where your coating and base metal stand today. NWTI’s surveys create that baseline, so maintenance dollars go to the worst spots first and safe assets stay in service longer.

How we help

A certified AMPP inspector walks every structure, starting with visual verification of existing coatings and steel members, then grading corrosion severity against ISO 4628-3 and ASTM D610 benchmarks. Next comes rust-distribution mapping per SSPC VIS-2, adhesion pulls, and a run of dry-film-thickness and profile readings following SSPC PA-2 and ASTM D4414. Each reading, photo, and ambient-condition log goes into a digital report that flags high-risk areas and recommends repair options. You finish with a clear, data-driven plan instead of a guess.
