Galleys & Mess Areas

GMSM is an expert when it comes to stainless steel galleys! We understand the necessity to maintain a clean environment when it comes to the galley area and this is why the majority of our customers request stainless steel as the foundation to their custom galley. We also happen to be an expert at refrigeration, HVAC, Duct Cleaning and just about any type of metal fabrication you want! Galleys always need a lot of storage space. This is where our joiner work experience shines! Contact Us about your custom project today!
