What is the load-bearing capacity of door hinge components
Information summary：The load-bearing capacity of door hinges varies due to various factors, and common situations are as follows:
1. Load bearing capacity of common types of door hinges
Ordinary home door hinges: Generally speaking, ordinary stainless steel or zinc alloy door hinges commonly used in homes have a load-bearing capacity of around 25-50 kilograms per hinge. For example, Ranbo's 3-inch heavy-duty
The load-bearing capacity of door hinges varies due to various factors, and common situations are as follows:
1. Load bearing capacity of common types of door hinges
Ordinary home door hinges: Generally speaking, ordinary stainless steel or zinc alloy door hinges commonly used in homes have a load-bearing capacity of around 25-50 kilograms per hinge. For example, Ranbo's 3-inch heavy-duty 304 stainless steel double spring hinges have a load capacity of 25 kilograms per pair. If it is a high-quality and thick hinge, such as the Stanford door and window hardware hinge, it is made of 304 stainless steel or zinc alloy material with a thickness of 3mm or more, and the load-bearing capacity can reach more than 50 kilograms.
Heavy duty door hinges: Heavy duty hinges used for industrial plant doors, large safety doors, etc., with much higher load-bearing capacity. For example, the industrial hinge JL-301 of XunDing stainless steel 304 heavy-duty door can withstand a weight of 80-100 kilograms. The adjustable door hinges (1.91 cm x 17.78 cm) of WELDANDFABSHOP are made of alloy steel material and can withstand a weight of up to 600 pounds (approximately 272.2 kilograms).
Child mother hinge: commonly used for indoor doors, its load-bearing capacity is generally 50 kilograms.
2. Factors affecting the load-bearing capacity of door hinges
Material: Steel, stainless steel and other materials have high strength and rigidity, suitable for bearing large weights; 304 stainless steel has good corrosion resistance and can extend its service life while ensuring load-bearing capacity. Aluminum alloy material is relatively lightweight and has good strength, often used for doors that require weight and aesthetics.
Thickness: The thicker the hinge, the stronger its load-bearing capacity is usually. Thicker hinges are less likely to bend or deform when subjected to force, and can better distribute the weight of the door.
Structural design: A reasonable structure can improve the load-bearing capacity. If the hook groove principle is adopted and the hinge is borrowed from the mortise and tenon structure, the force can be evenly distributed throughout the hinge, increasing the overall firmness.
