Ordinary hinges
This type of hinge has a simple structure and a relatively low price. It is suitable for general weight industrial doors, but may not be able to provide sufficient support for particularly heavy doors.
Heavy duty hinges
Specifically designed to withstand the weight of heavy industrial doors. Usually made of high-strength materials for greater load-bearing capacity and better durability.
Spring Hinges
With a spring mechanism that automatically closes the door when it is opened. Suitable for applications where automatic door closing is required, such as warehouse doors, workshop doors, etc.
Hydraulic Hinge
With hydraulic cushion device, it can realize the slow closing of the door and reduce the impact force when closing the door. It is very suitable for the occasions that need to open and close the door frequently and have requirements for closing speed.
Second, consider the weight and size of the door
Determine the weight of the door
Before purchasing heavy duty industrial door hinges, the first thing to do is to accurately measure the weight of the door. Different types of hinges can withstand different weights, the choice of hinges must ensure that its carrying capacity is greater than the actual weight of the door. Generally, you can refer to the product manual of the hinge or consult the manufacturer to determine the appropriate hinge model.

Check the quality and workmanship of hinges
Appearance quality
Check whether the surface of the hinge is smooth, no burr, no cracks and other defects. Good appearance quality can not only improve the beauty of the hinge, but also reflect the level of its manufacturing process.
Dimensional accuracy
The dimensional accuracy of hinges directly affects the installation and use of the door. When purchasing, check whether the dimensions of the hinges meet the standard requirements, especially whether the position and size of the mounting holes are accurate.
Welding quality
For welded hinges, it is necessary to check whether the welded parts are firm, free of air holes, no slag and other defects. The quality of welding is directly related to the strength and durability of the hinge.
Surface treatment
Surface treatment can improve the corrosion resistance and aesthetics of hinges. Common surface treatment methods include galvanization, spraying, chrome plating and so on. Choose hinges with good quality and uniform surface treatment.
Fifth, consider the installation and maintenance of hinges
Installation
Heavy industrial door hinges can be installed in various ways, such as welding, bolting and so on. When choosing hinges, consider the structure and installation conditions of the door and choose the appropriate installation method. At the same time, it is necessary to ensure that the installation process is simple and fast to reduce the installation cost and time.
Ease of maintenance
Choosing hinges that are easy to maintain can reduce the maintenance cost at a later stage. For example, some hinges come with removable parts, which is convenient for repair and replacement. In addition, choose hinges with good lubrication performance to reduce wear and prolong service life.
Sixth, refer to the brand and reputation
Choose well-known brands (Haisepu)
Heavy-duty industrial door hinges from well-known brands usually have better quality and performance guarantees. These brands usually adopt advanced technology and strict quality control system in the production process to ensure the reliability and stability of the products.
