Built for chloride exposure.
304 stainless components survive direct salt contact and the airborne chloride load that destroys standard hardware.

The problem
Salt storage corrodes painted galvanized faster than any other building.
Bulk road salt and the brine that drips off plow trucks creates a chloride atmosphere most overhead doors weren't engineered for. Painted galvanized hardware shows surface rust within months and structural corrosion within a season or two.
The maintenance burden falls on whoever runs the facility. DOT districts, county highway departments, municipal public works. Doors are out of service when the building is most needed.
Stainless avoids the failure mode entirely. SSGDP packages are engineered to live in salt-loaded buildings without the seasonal callback cycle.
Why stainless
Three reasons stainless is the DOT standard.
Reduced maintenance budget.
Districts that switch to stainless typically eliminate the every-other-season replacement cycle. Capital up, maintenance way down.
Spec-ready for state contracts.
Submittals and material certs available on request. Our team works with DOT engineers and architects on facility builds.
