Our History

SIMPSON STRONG-TIE 1956

  • simpson screen co

On a Sunday evening in the summer of 1956, Barclay Simpson's doorbell rang. A neighbor's brother had stopped by to ask if he could make a product to connect the ends of 2x4s for a roof. Barclay replied, "Of course!" So he sat down with his plant foreman, developed some rough sketches and used a punch press to create his first joist hanger.

That simple beginning was about more than just solving problems. For Barclay, it was about putting the customer first. Our phrase–"Our customers are our bosses"– is a simple philosophy that permeates all that we do.

At Simpson Strong-Tie, it's about enjoying what we do, doing it right and supporting our customers every step of the way–from order placed to product installed.

Today, Simpson Strong-Tie is the world leader in structural product solutions–solutions that not only help our customers, but help make structures safer and stronger. The company is recognized as the genuine connector brand in the residential construction industry, and also for its ever-expanding offering of shearwalls, moment frames and fasteners. In the last two decades, the company has expanded further with products for infrastructure, commercial and industrial construction, including mechanical anchors, adhesives and products that repair, protect and strengthen concrete and masonry.

But even with all of the growth, we still keep it simple, focusing on the core values that Barclay instilled and living up to our reputation of reliability, innovation, quality and service.
