Welcome to GMSM Custom Metal Fabrication


GMSM is a leader in custom metal fabrication.  We are experts with most metals, especially stainless steel.  We take pride in every project  we design and build for our customers. We know how important your project is to the success of your business. We use stainless steel when designing and building a lot of our projects because stainless steel resists stains, corrosion, heat damage, chemical damage and stainless steel is extremely strong and durable! "The steel used to make "stainless steel" comes from a low carbon steel. A lot of stainless steel has its properties because of the addition of chromium. A unique ability of stainless steel is that it has the ability to "heal itself". The chromium allows for the formation of an invisible chromium oxide film on the surface of the steel. If the steel becomes damaged and is exposed to oxygen in any amount, the steel becomes "self-healing".. sort of speak! When other elements, such as nickel, nitrogen and molybdenum are added during the manufacturing process, the corrosion resistant properties are increased. While there are currently over 60 different grades of stainless steel available to choose from, they all fall neatly into five distinct classes that are identified by the alloy elements that are added to enhance or strengthen their properties. Our stainless steel projects have 5 major advantages which can help make it easier for having a successful businesses. ( The Amazing abilities and advantages of stainless steel ) The advantages are: 

  • Easy to clean and maintain.
  • Long life span.
  • Does not harbor germs.
  • Aesthetically pleasing.
    Does not affect flavor of foods.
