1. Marine Grade Stainless Steel – 316 Alloy
316 stainless steel contains molybdenum, which significantly increases resistance to pitting and crevice corrosion—the kind commonly caused by salt and chlorine.
-
? Ideal for seafront buildings, bridges, piers, spa zones, and pool surrounds.
-
? Maintains appearance even in aggressive environments.
-
? Available in woven meshes, profiled metals, perforated sheet and laser-cut panels.
We offer 316 finishes in brushed, satin, or mirror polish, and even PVD-coloured stainless for a decorative yet highly resilient option.
2. Marine-Grade Powder Coating
Powder coating is often specified for coloured finishes—but not all powders are created equal.
Marine-grade powder coatings include:
We use suppliers whose products meet Qualicoat Seaside Class or ISO 12944 C5 standards for maximum durability.
For mesh and perforated panels in aluminium or mild steel, this is a versatile and weatherproof solution—particularly when paired with a robust pre-treatment process, like chromate or zinc phosphate conversion.
3. Electroplating
For smaller components or decorative elements, electroplating offers a layer of metal deposited onto the base material, providing both aesthetics and protection.
In coastal environments, consider:
Electroplating is best used for internal fixings, decorative grills, and furniture-scale elements, where the base metal is less exposed.
4. Anodising – Especially for Aluminium
Anodising transforms the surface of aluminium into a durable, oxide-rich finish that resists corrosion, abrasion, and fading.
-
Marine anodising uses Class 1 (25 micron) thickness for external environments.
-
Finishes range from natural silver to bronze and black tones.
-
Ideal for façade panels, solar shading, and decorative aluminium meshes.
Anodised aluminium also holds colour extremely well, making it suitable for long-term visual consistency in seaside architecture.
