Since 1968 Coyle Supply, a family owned and operated business located in the St. Louis, Missouri metropolitan area, has offered unparalleled service and competitive pricing as a supplier in the pipe, valve and fitting industry to industrial customers, large and small. Now in its second generation, Coyle Supply is more than just a supply house. We also have a full line of valve automation and specialty products to meet the increasingly complex demands of the market.

In addition to our headquarter location Granite City, Illinois, Coyle Supply now has two additional stocking facilities, one in East Alton, Illinois and another in Springfield, Missouri. We carry a large stock of local inventory serving the St. Louis region, Missouri and beyond. Because we are centrally located in the Midwest, transportation costs tend to be lower than from east and west coast suppliers.

In addition to the quality products we sell, our experienced and knowledgeable sales staff and technicians allow us to advise our customers on which products are best for them, lowering their costs and improving the overall project. By providing analysis and consulting services, we have been able to retain long-term relationships with many of our customers. Although we have large and small customers and welcome isolated sales opportunities, today 90% of our business is MRO/contract management and supply.
