Stainless, every part of the door.
From the track to the smallest fastener, we engineer every component in stainless. No mixed-metal galvanic surprises three years in, no painted-over compromise.
SSGDP exists because our founder spent his career on the job, watching painted galvanized hardware corrode through in the same handful of environments. Wash bays. Wastewater treatment plants. Salt-storage buildings. Industrial facilities where the air carries moisture and chemistry that off-the-shelf hardware was never engineered to survive.
The standard answer was a callback every 18 months. The better answer was hardware made of a metal that wouldn't rust in the first place.
SSGDP is a division of American Garage Door Supply, Inc., a family-run distributor founded in 1984. Our stainless line is proprietary, partly patented, and built to outlast the doors it equips by 5 to 10 times the working life of standard hardware.
