To Provide Exceptional Value Through Innovative and Durable Building Products, Delivered with Superior Customer Service.


The Marwin Company Inc. has been family owned and operated for over seventy years. Because the quality of how we do business reflects on our family name, we take exceptional pride in delivering the highest quality products, service and value.

Marwin's founder, Mr. Jesse Davis, launched the company in 1947 from a 5000 sq. ft. building in Cayce, South Carolina to fill a need for general building products that was lacking in the area. The company name derived from three letters from each of his son’s names, MARion and edWIN, hence the name MARWIN.

During the building boom that followed World War II, Jesse discovered there was a growing need for a quality folding attic stairway, so he decided to make that the first product manufactured by his young company. In 1954, Marwin moved to an expanded location on Atlas Road in Columbia, South Carolina. In 2014, Marwin greatly increased its manufacturing footprint by moving to its present location on McQueen Street in West Columbia, South Carolina.

Today, the company is run by Jesse’s grandson, Andy Davis (Edwin’s son). To maintain Marwin’s excellent reputation in the industry for years to come, an energetic, customer-focused team of employees has been assembled that is dedicated to producing quality products and providing excellent customer service.

Service, Quality Products and Flexibility have been the key ingredients for The Marwin Company as we have serviced customers from Florida to Maine to Texas and beyond. Adding value to what we do is our core philosophy. This, together with honesty, loyalty and fairness, has enabled The Marwin Company to maintain a loyal customer base - some as long as forty years.
