FAST PRODUCTION, HIGH QUALITY, ON TIME SHIPPING. IT’S WHAT WE DO.

Anodizing

  • Clear & color – 10-minute to 1-hour anodize – up to 40-foot lengths.

  • Two-step – three shades of bronze or black – up to 40-foot lengths.

  • Clear Brite Dip – decorative finish with silver appearance – up to 21-foot lengths.

  • Gold Brite Dip – decorative finish with brass appearance – up to 21-foot lengths.

  • Hard Coat Aluminum Anodizing – Type III, class 1 and 2 – up to .002″ thickness and 20-foot lengths.

Painting

  • Chromate conversion coatings – clear and yellow- mill specifications- paint preparatory finishes.

  • Regular and electrostatic painted finishes – including polyester and acrylic finishes.

  • Kynar – high-performance finish for exterior applications in polyester, epoxies, hybrids, and polyurethanes.

  • Silk screening – custom screen-printing to include your company’s name or logo and complete your part.

Polyesters (TGIC free) – TGIC free polyester-based powder coatings are designed for the exterior environment, offering excellent light and weather resistance from a single coat finish on a variety of substrates. The enhanced heat resistance makes them ideal for use where color retention on surfaces exposed to continuous heat is required.

Epoxies – Epoxy-based powder coatings are designed to give optimum mechanical performance and exceptional protective qualities on fabrications and components where long-term exposure to ultraviolet light or exterior weathering is not anticipated.

Epoxy/polyesters (hybrids) – Epoxy/polyester hybrid powder coatings offer improved color, ultraviolet light and heat stability when compared to pure epoxies. They maintain an optimum combination of decorative and protective qualities.

Polyurethanes – Thermosetting polyurethane powder will provide excellent corrosion resistance and flexibility properties with good gloss and color retention when subjected to outdoor weathering conditions.

Powder Coating

Mechanical Finishes

  • Sanding for finishes similar to brushed finish with grains from very fine to heavy.

  • Polishing for a highly decorative mirror-like finish is usually combined with anodizing.

  • Mechanical Brushing for picture frames, shower/tub enclosures, etc.

  • Bead Blasting & Hammering for a worn, rustic look to your extrusions.

  • Tumbling for a completely deburred part with smooth corners.
