Our History

About Us: A.B. Martin

It was a small beginning in 1947 when Amos B. Martin began selling metal panels to his Lancaster County neighbors for their chicken shelters.  Fast-forward 75 years and AB Martin is one of the fastest-growing building supply companies in the Northeast.  Over 19 million feet of metal panels come off our machines each year. Our full history is told in the book More Than Roofing.


Today, AB Martin is your one-stop-shop for all things building related.
