Quality Control starts at G.G. Schmitt’s loading docks. Our engineers first certify that the stainless steel and aluminum raw materials we buy meet our exacting specifications. G.G. Schmitt uses only Type 304 and Type-316 wrought stainless steel – the purest form of the alloy and 6061-T6 marine and aircraft grade aluminum. During the manufacturing process, technicians scrutinize the process to ensure each product meets strength and dependability specifications established during its design and development. Inspections and testing continues through final packaging.
