Powder Coating for Steel Structures — Manufacturer

TriNu coats a wide range of structural steel, including beams, columns, plates, brackets, gusset assemblies, stair stringers, mezzanine framing, guardrails, frames, and large custom fabrications. The 10' × 10' × 30' production oven supports long and oversized steel parts that many smaller coating shops cannot process efficiently or consistently.

Powder coating is a strong option for structural steel when the surface is properly prepared and the coating system matches the environment. It provides a durable, uniform finish with corrosion resistance, strong adhesion, and clean appearance. For outdoor, coastal, industrial, or architectural use, coating selection and preparation are especially important for long-term performance.

Yes. TriNu offers surface preparation services such as sand blasting, abrasive blasting, grit blasting, and shot blasting as part of the full powder coating workflow. Proper preparation removes rust, mill scale, old coatings, and contaminants while creating the anchor profile needed for adhesion, durability, and consistent coating performance.

TriNu’s large-scale production oven measures 10' × 10' × 30', allowing the team to coat oversized fabrications, long beams, large frames, railing runs, DOT components, and structural assemblies. Project fit also depends on weight, geometry, racking requirements, and handling access, so dimensions should be reviewed before scheduling.

Yes. TriNu works with manufacturers, fabricators, OEMs, and contractors that need finishes aligned with project specifications, TDS requirements, AAMA Certified Products, mil-spec capability, or documented inspection needs. The process is built around controlled preparation, application, curing, and final quality checks so repeat work can remain consistent batch after batch.

Pickup and delivery are available across the Tampa Bay region for many projects, including oversized fabrications, palletized production runs, and recurring manufacturer work. Logistics can be included or quoted per project. This helps reduce handling damage, simplify coordination, and keep parts moving through fabrication, coating, and installation schedules.

Pricing is project-specific and generally depends on part size, weight, quantity, coating type, surface condition, masking requirements, blasting needs, handling complexity, and delivery logistics. Structural steel projects often require a review of drawings, photos, dimensions, and specifications before quoting so the price reflects the actual preparation and coating work required.

Yes. Every job is inspected before release to confirm finish quality, consistency, and workmanship. For manufacturers and fabricators, this final check helps reduce rework, protect downstream schedules, and ensure coated steel arrives ready for the next production, assembly, delivery, or installation step.
