Our Protective Marine Coatings for Steel Services

Complete surface preparation, coating, inspection, and logistics support for steel exposed to marine and coastal environments.

Marine Coatings

Marine and coastal powder coating for dock hardware, boat trailers, railings, davits, frames, and outdoor steel exposed to salt air, UV, humidity cycling, and harsh service conditions.

Structural Steel

Durable powder coating for beams, columns, brackets, stair stringers, mezzanine framing, and miscellaneous steel requiring long-term performance in humid or coastal construction environments.

Large-Part Coating

Oversized steel fabrications up to 30 feet are handled in TriNu’s 10' × 10' × 30' production oven, supporting long rails, frames, poles, and structural assemblies.

Abrasive Blasting

Controlled abrasive blasting removes rust, mill scale, old coatings, and contaminants while preparing the steel substrate profile for stronger coating adhesion and longer service life.

Grit Blasting

Aggressive grit blasting creates a precise anchor profile on heavily corroded or irregular steel surfaces, improving adhesion readiness for advanced protective coating systems.

Industrial Coatings

Integrated coating solutions combine surface prep, powder application, verified curing, inspection, and logistics into one accountable workflow for manufacturers and fabricators.
