Construction projects need reliable suppliers who understand timelines, can handle volume, and deliver consistent results. At Coating Lab, we work with builders, fabricators, and project managers throughout Auckland on everything from individual site metalwork to large-scale flashings programmes.
Our in-house folding and fabrication capability means we can take a project from flat sheet to finished, coated component — a significant advantage for builders who want one supplier managing both fabrication and finishing.

Balustrades & Gates
Balustrades, handrails, and gates are standard parts of residential and commercial construction projects. We coat these in any specified colour, maintaining consistency across the full volume of a project.
