Description
It is a type of door hardware primarily made of steel, designed to keep doors in an open state and prevent accidental closure, thereby avoiding collisions and safety hazards. It is widely suitable for high-traffic public spaces such as trucks, cargo trailers, campuses, and hospitals.
Mainstream Material Classification
Galvanized steel: High strength and excellent cost performance, commonly used in door positioning scenarios for general dry cargo freight vehicles.
Stainless steel: Excellent corrosion resistance, suitable for use in refrigerated vehicles and outdoor environments with high humidity and salt exposure.
Typical Product Parameters
Common galvanized steel door positioners typically feature a claw-type structure with a zinc-plated anti-rust surface and matching mounting holes. Some heavy-duty models utilize a zinc alloy base combined with a steel magnetic attraction mechanism, suitable for large, heavy door bodies.
Core Usage Advantages
The steel structure is impact-resistant and wear-resistant, capable of enduring high-frequency usage and harsh working conditions over the long term
