The Alloy Gravity Hinge from Bolton Industries is a self-closing door hardware fitting designed for applications requiring automatic door closure without external springs. These hinges leverage gravitational force to ensure doors return to a closed position, making them ideal for fire-rated assemblies, public buildings, hospitals, and offices. The product is manufactured from high-strength aluminum alloy or zinc alloy, depending on the grade and load capacity requirements.
Gravity hinges are standardized export commodities, traded in bulk quantities with specifications influenced by material composition, load-bearing capacity, and finish. Bolton Industries offers variants in aluminum or zinc alloys, which provide durability and corrosion resistance for high-traffic environments. The hinge’s design ensures smooth operation and longevity, even under frequent use in commercial settings.
Buyers of this product include contractors, architects, and facility managers sourcing door hardware for new constructions or retrofits. The hinges are particularly specified in projects where fire safety and accessibility compliance are critical. As a bulk-traded commodity, pricing and lead times are typically negotiated based on order volume, material grade, and finish specifications.
