Engine Room Warning Sign — 316 Marine-Grade Stainless Steel

A precision CNC-cut compliance sign manufactured from 2mm thick 316 marine-grade stainless steel — built to withstand the harsh environment of engine rooms and helm stations aboard commercial vessels, charter boats, and offshore yachts.

Required by the USCG (46 CFR) for commercial vessels, this placard is suitable for mounting in the engine room, at the helm station, or both. CNC-etched lettering ensures high visibility even in low-light or high-vibration conditions, meeting professional safety and compliance standards.

Fully custom text — we can engrave anything you need on your sign. Simply leave your desired wording in the order notes at checkout, or contact us before ordering. Whether it's a standard compliance message, a vessel name, a warning, or any other label, we'll cut it exactly as specified.

Each sign is cut and finished by M.Square Marine to order using the same 2mm 316 stainless steel used across our full line of marine signage and lettering. Fixings and mounting hardware are compatible with fiberglass, aluminum, and teak substrates.
