Helping Customers Solve Problems

Our founder, Barclay Simpson, started our company with a simple belief—help customers solve problems. Barc did just that when he created our first joist hanger in 1956 for a customer who needed to make a roof connection. Today, we have many more solutions to meet customers' construction needs with our full product offering of structural connectors, fasteners, fastening systems, anchors, lateral systems, software, and concrete repair, protection and strengthening systems.
