Powder Coating for Architectural Metalwork

Balustrades and handrails are visible, high-touch elements of a building — they need a finish that looks sharp and holds up to daily contact. Powder coating delivers both: a factory-quality finish that's tougher than paint, available in any architectural colour, and consistent across every component in a run.

At Coating Lab in Onehunga, we work on balustrade and handrail projects for builders, architects, steel fabricators, and homeowners across Auckland. From a single residential staircase to full commercial fit-outs, we deliver consistent, quality results.

Balustrades and Handrails We Powder Coat

  • Steel balustrades — flat bar, round bar, and fabricated panel styles
  • Aluminium handrails — extruded and fabricated profiles
  • Staircase handrails — residential and commercial
  • Glass balustrade framing — posts, base channels, and top rails
  • Deck and balcony railings — interior and exterior
  • Commercial stair and corridor handrails — offices, retail, hospitality
  • Juliet balcony panels and window grilles

Architectural Colour Matching

Getting the colour right matters on architectural projects. We offer:

  • Full RAL colour range — the standard for architectural metalwork specifications
  • Resene and Dulux colour matching — match your balustrades to your wall or exterior colour scheme
  • Custom colour matching — bring us a reference colour or specification and we'll achieve the closest available match
  • Consistent batch coating — all components from the same project coated together to ensure colour uniformity

Residential and Commercial Applications

We handle both residential and commercial balustrade and handrail projects:

  • Residential: New build staircase handrails, deck balustrades, interior feature railings, renovation colour changes
  • Commercial: Office and retail stair handrails, hospitality mezzanine balustrades, apartment common areas, educational and healthcare facilities

For commercial projects requiring multiple components to match exactly, we coat complete batches together. We regularly handle large commercial volumes, including full building balustrade packages.

Restoring Existing Balustrades

If existing handrails or balustrades are faded, chipped, or need a colour refresh, powder coating restoration is an effective option. We sandblast existing metalwork back to bare metal, then apply a fresh coat. This is particularly cost-effective for steel components that are structurally sound but cosmetically tired.

Why Powder Coating for Balustrades

  • Scratch and wear resistance: Handles daily hand contact without scuffing or wearing through
  • Consistent coverage: Even on tubular and complex profiles, no runs or thin spots
  • Colour accuracy: Factory-applied finish matches specifications precisely
  • Interior and exterior suitability: Same process, same durability, whether inside or outside
  • No drips, brush marks, or overspray: Cleaner result than site-applied paint
