The Marwin Company Inc. has been family owned and operated for over fifty 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.

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 its present location on Atlas Road in Columbia, South Carolina.

Today, Jesse's two sons, Marion and Edwin Davis run the company. The company name derived from three letters from each of their names, MARion and edWIN, hence the name MARWIN. To maintain consistent quality and service for years to come, a third generation is being groomed to take over the family business.

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. 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.

So, before you purchase specialty building products, MAKE SURE IT'S MARWIN MADE.
