Three materials. Each chosen
for a reason.
We don't offer a catalogue of options padded out to look impressive. Every material we stock has earned its place by surviving what the sea throws at it.
316L Stainless Steel
Marine-grade 316L — the "L" is critical. It denotes low carbon content (≤0.03%), which prevents carbide precipitation along grain boundaries. The molybdenum content (2–3%) pushes the pitting resistance index above 25 — the minimum threshold for marine chloride environments.
Our steel carries a Mill Certificate with each batch confirming composition. We don't accept "stainless" without documentation. Neither should you.
Naval Brass
C46400 naval brass — the same alloy specified for marine propeller shafts and through-hull fittings. The "naval" designation means it contains tin (0.75–1.25%), which suppresses dezincification — the process by which ordinary brass loses zinc ions in salt water, becomes porous, and ultimately fails.
Our brass arrives as flat stock, is sheared to blank, CNC-routed, then passed to our finishing team who cold-work the surface through four progressively finer grits before buffing to a mirror.
Premium Acrylic
+ RGB LED
Cast sheet (not extruded) — significantly better optical clarity, surface hardness, and UV stability. UV stabilisers dosed for a ten-year no-yellowing guarantee under direct sun exposure, tested to QUV-A accelerated weathering standard.
The LED strip is IP68 — fully submersible. We machine a recessed channel so the strip sits flush and protected. Light disperses evenly through the material using the same edge-lit principle as high-end display panels. No hot spots. No visible source.
