Structural steel and machinery coatings

Protective coatings for structural steel, machinery, and equipment, so rust, chemicals, and weather don’t shorten their life.

Overview

Steel coatings that last

Steel is tough until water, salt, chemicals, and heat get to it. Structural steel painting and machinery coatings seal the metal against those things. We prep the surface, pick the right system, and apply it so it lasts.

Stopping rust before it starts

Most rust comes from a few things: chlorides from salt air, de-icing salt, or process chemicals; plain steel touching stainless; moisture and salt buildup at coastal sites; and big temperature swings. Even stainless steel corrodes under the wrong conditions. We look at what the steel is exposed to before we pick a coating, because no single coating works on every alloy or in every environment.

Prep is part of every steel job

Contaminants come off first: oil, dust, moisture, mill scale, and any rust. On most steel that means abrasive blasting with non-metallic media, which also gives the surface a profile the coating locks into. We line up the blasting as part of the coating job and manage it, so you deal with one contractor.

FAQ

Common questions

More FAQs
Can you coat equipment where it sits?

In most cases, yes. We mask and contain the area and coat equipment in place during a shutdown or between shifts. Some smaller pieces are better done off-site. We’ll tell you which on the site visit.

How often does structural steel need recoating?

It depends on the exposure and the system. Interior steel in a dry plant can go many years; coastal, chemical, and wet exposures need attention sooner. A maintenance program catches the spots that go first so the whole structure doesn’t need to be redone.

Do you fireproof steel too?

Yes. We apply intumescent fire protective coatings on beams, columns, and exposed steel, rated for 1 to 3 hours.
