Garage doors, frequently utilized as facility access points by businesses, are widely deployed across various sectors, including commercial storefronts. The garage door types commonly found on the market fall into three main categories: remote-controlled, electric, and manual. Remote-controlled, sensor-activated, and electric garage doors are collectively referred to as "automatic garage doors," whereas manual garage doors lack a motor and therefore cannot operate automatically. Currently, automatic garage doors are primarily classified into two major categories: sectional garage doors and rolling shutter garage doors.
Hardware Components
Guide Rails: Integrally formed from 1.5mm-thick galvanized steel plate, ensuring stability and durability.
Side Hinges: Supported by 1.5mm steel plates; treated via blue-white galvanization and acid-pickling/phosphating processes to ensure rust resistance and corrosion protection.
Rollers: Feature embedded imported bearings encased in a die-cast white nylon outer layer; designed to be wear-resistant and anti-aging, ensuring long-term operational longevity.
Springs: Constructed from #70-grade steel with high torsional/tensile strength; treated with electrophoretic coating for rust prevention, providing consistent and stable elastic force.
Sealing Strips: High-durability, anti-aging sealing strips are installed at the interface between the door panel and the guide rails; these eco-friendly and cold-resistant seals resist deformation over time, effectively shielding against wind, sand, and rain.
Other Hardware: All other metal components are precision-crafted from high-quality cold-rolled steel plate; they undergo hot-dip galvanization or blue-white galvanization treatments, with a baked-on paint finish applied to the surface to further enhance durability.
