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.
Durable powder coating for beams, columns, brackets, stair stringers, mezzanine framing, and miscellaneous steel requiring long-term performance in humid or coastal construction environments.
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.
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.
Aggressive grit blasting creates a precise anchor profile on heavily corroded or irregular steel surfaces, improving adhesion readiness for advanced protective coating systems.
Integrated coating solutions combine surface prep, powder application, verified curing, inspection, and logistics into one accountable workflow for manufacturers and fabricators.

We review steel type, part size, exposure conditions, performance needs, and project schedule before recommending the right surface preparation and powder system for marine or coastal service.
