Thickness: We use 14 & 16 gauge stainless. The sheets are bonded to solid, waterproof MDF. Edges can be built up to any desired thickness, although 1-1/2" is standard. We are able to seamlessly weld together sheets of stainless to accommodate various lengths and shapes in your design. Please contact us with specific engineering questions. We are able to fabricate seamless cabinets, shelving, wall and door panels and furniture with stainless steel.
