Simpson Strong-Tie, the leader in engineered structural connectors and building solutions, is honored to mark 70 years of innovation and manufacturing in 2026. 

Barc Simpson founded the company in 1956 when his neighbor’s brother asked him whether he could make a product to connect 2x4s for a roof. Believing as always in taking a chance, Barc created a joist hanger using a punch press at his father’s window screen factory in Oakland, California. Since then, the company has been leading the building industry with engineered structural connectors and solutions defined by innovation, integrity and an unwavering commitment to quality and safety. 

“Simpson Strong-Tie began with a simple problem to solve, and it sparked a movement that transformed how structures are built. Today, we continue to focus on building solutions that people can rely on, backed by engineering excellence, advanced technology, rigorous testing and a relentless focus on customer service,” said CEO Mike Olosky. “As we look to the future, Simpson is not only about delivering high-quality product and software solutions. It’s about people — our employees, customers and partners. It’s about the communities where we live and work. And it’s about continuing to break new ground, together, as we build a stronger tomorrow.” 

Here are just a few of the company’s product milestones across the past seven decades:

• (1956) First Connector: The F24 was Barc’s entry into the connector business, with his first order totaling 25,000 units at 10 cents each.
• (1957) Reinforced Angle Brackets: The versatile A34 and A35 reinforced angle brackets make 90° connections; the A35’s exclusive bending slot allows instant field bends for two- and three-way ties.
• (1957) Face-Mount Hanger: The face-mount U hanger provides easy joist-to-header installation in wood-framed construction. 
• (1965) Strap Product: The ST strap tie resists tension loads across various applications. Ideal for cut plates, wall intersections and ridge ties with quick installation and optimal performance.
• (1966) First Holdown (HD): Simpson introduced the first HD welded holdown to secure posts to foundations. 
• (1972) Hurricane Tie (H Series): The H1 hurricane tie connects trusses or rafters to walls, helping structures resist wind and seismic forces.
• (1978) Architectural Product Line: Simpson introduced black powder-coated connectors, originally called “Ornamental Connectors,” still sold today as Architectural Products.
• (1984) Double-Shear Connector Patent Issued: Simpson received a patent for the double-shear angled fastener connector, which dramatically increased load values by using nails in double shear.
• (1993) Simpson Entered the Fastener Market: With the launch of the SD8 DIY screw, Simpson expanded beyond its main connector and anchor offerings.
• (1995) Ackerman Johnson Acquired: Product category expansion continued with the acquisition of Ackerman Johnson, a manufacturer of chemical and mechanical anchors for concrete fastening systems. The company launched new mechanical and adhesive anchors the following year.
• (1998) Strong-Wall^® Shearwall Introduced: Simpson launched the Strong-Wall shearwall with a patented shape and industry-leading allowable loads. 
• (2003) Tyrell Gilb Research Laboratory Opened: The $10 million, 25,000-square-foot lab opened with specialized equipment to test a structure’s resistance to extreme winds and earthquakes. The facility was named for Tye Gilb, the company’s first head of product who created 70 patented designs during his 35-year tenure.
• (2017) Builder and LBM Software Acquisitions: Simpson acquired CG Visions (BIM technology), later adding LotSpec (automated lot documentation) and SpecItUp (plan specification tools) to expand its software offerings. 
• (2023) Mass Timber Product Line: Simpson expanded its reach into mass timber products, including aluminum concealed beam hangers, steel splines, screws, tension straps and angle brackets for faster construction.
• (2025) Outdoor Decorative Hardware for DIY: Simpson expanded its Outdoor Accents^® decorative hardware line with the launch of the Sage System™ DIY-friendly modular pergola kit.

Over these same periods, Simpson Strong-Tie progressively reinforced its commitment to giving back to communities and investing in current and future employees. These efforts include donating more than $2 million in student scholarships. Each year, the company also recognizes Community Heroes, those employees, partners and volunteers who go above and beyond to make a difference and who reflect the values — service, integrity and innovation — that have guided Simpson Strong-Tie for 70 years.
