From a quick rail repair on the dock to a full sanitary piping run for a new brewhouse, we work in the materials and standards your project demands.

About the Shop

Trade craft. Marine grit. Brewery clean.

A small, owner-operated welding and pipefitting outfit serving the two industries we know best — the water and the brewhouse.

West Coast Aluminum Outfitters was built on the belief that a clean weld is a safe weld, and that a contractor's word should mean the same on day one and day three hundred. Whether we're patching a hull on a haul-out or running a new glycol loop overnight so a brewery doesn't lose a brew, we show up prepared, communicate honestly, and leave the work better than we found it.
