Simpson makes the metal connectors, fasteners, and anchors that hold wooden buildings together.
Simpson Manufacturing makes the hidden metal parts that keep buildings from falling apart. If you've ever seen a house being framed, those metal brackets, straps, and nails holding the wood together — a lot of them come from Simpson. The company sells to lumber yards, building materials dealers, and contractors, mostly in the United States, though it also operates in Europe and Asia. Its two main product lines are wood connectors and fasteners, which make up roughly three-quarters of sales, and concrete construction products like anchors and adhesives, which bring in the rest.
Think of it as the seatbelt for a house. You don't see it, but without it the whole structure is far less safe. Builders choose Simpson because its products are engineered and tested to meet strict building codes — and inspectors know the Simpson name. That reliability, plus a huge catalog of parts and strong relationships with dealers, keeps customers coming back.
Simpson was founded in 1956 and has grown partly by buying other companies, including smaller rivals in Europe and concrete anchor makers. The business throws off a lot of cash. Management uses that cash to pay a small dividend, buy back shares, and fund acquisitions. Lately, the company has been pushing into new products like software that helps engineers design connections faster, and it's expanding its concrete and European businesses. The main risk? When housing construction slows, Simpson feels it — but because its products are required by code, demand holds up better than you might expect.
