Our Modern Tech 3550 steel garage door offers the Beauty of Aluminum with the Strength of Steel. A steel face and a 2 inch thick R10.4 expanded polystyrene (EPS) core makes the Modern Tech 3550 extremely strong and energy efficient.
It is built using our time-proven sandwich-type construction method and comes in four finishes: Black Satin, Dark Bronze, Brushed Nickel and Bright White.
