In the industrial field, the choice of heavy duty industrial door hinges is crucial, which is directly related to the safety, reliability and service life of industrial doors. As heavy duty industrial doors usually have larger size and weight, the requirements for hinges are also higher. The following will provide you with a detailed introduction to the purchase of heavy duty industrial door hinges strategy.
First, understand the importance of heavy duty industrial door hinges
Heavy duty industrial door hinges are the key components connecting the industrial door and the door frame, which bear the weight of the door and ensure that the door can be opened and closed smoothly. A quality heavy duty industrial door hinge not only provides strong support, but also maintains stable performance over time, reducing the cost of repairs and replacements. At the same time, the right hinges can also improve the safety of industrial doors, preventing the door from accidentally falling off or damaged in the process of use.
Second, determine the needs and use of the environment
Door size and weight
Before buying heavy duty industrial door hinges, you first need to understand the size and weight of the door. Doors of different sizes and weights require different sizes of hinges to support them. Generally speaking, the larger and heavier the door is, the more weight-bearing capacity of the hinges required. The specifications of the hinges required can be determined by measuring the height, width and thickness of the door, as well as estimating the weight of the door.
Environment of use
It is also important to consider the environment in which the industrial door will be used. If the door is installed in a harsh environment such as damp, corrosive or high temperatures, you will need to choose hinges with appropriate protection. For example, in a humid environment, you can choose stainless steel hinges to prevent rust; in a corrosive environment, you can choose corrosion-resistant special alloy hinges; in a high-temperature environment, you need to choose hinges that can withstand high temperatures.
Opening frequency and mode
The opening frequency and mode of industrial doors will also affect the choice of hinges. If the door needs to be opened and closed frequently, it is necessary to choose hinges with good durability and smooth opening. At the same time, if the door is opened automatically or remotely, you also need to choose the hinges that are compatible with it.
Third, understand the type and characteristics of heavy industrial door hinges
Ordinary hinges
Ordinary hinge is the most common type of heavy duty industrial door hinge, which consists of two blades and a shaft, and can realize the 180 degree opening of the door. The advantages of ordinary hinges are simple structure and cheap price, which are suitable for some occasions with not too high performance requirements. However, ordinary hinges have limited load-bearing capacity and a small opening angle, making them less suitable for large or heavy industrial doors.
Spring Hinge
Spring hinges add a spring mechanism on top of the ordinary hinges, which can realize the automatic closing of the door. The advantage of spring hinges is that they are easy to use and can improve the safety of the door. However, spring hinges also have a limited load-bearing capacity, and the life of the spring may be affected by the environment and frequency of use.
Hydraulic Hinges
Hydraulic hinges control the opening and closing speeds of the door by means of a hydraulic damping device, allowing for smoother door movement. The advantages of hydraulic hinges are low noise and low impact during opening and closing, which protects the door and door frame from damage. However, hydraulic hinges are relatively expensive and require regular maintenance and care.
Heavy duty hinge
Heavy duty hinges are a type of hinge specially designed for heavy duty industrial doors, which consists of multiple blades and a shaft with very high load bearing capacity and stability. Heavy duty hinges have the advantage of being able to withstand the weight of large or heavy industrial doors and have a large opening angle, making them suitable for a wide range of applications. However, heavy-duty hinges are more expensive and more complicated to install.
Fourth, choose the right material and surface treatment
Material selection
Heavy duty industrial door hinges are usually made of stainless steel, cast iron, aluminum alloy and so on. Hinges made of different materials have different characteristics and applicable occasions.
Stainless steel hinges: Stainless steel hinges have the advantages of corrosion resistance, abrasion resistance, high strength, and are suitable for all kinds of harsh environments. However, the price of stainless steel hinges is relatively high.
Cast iron hinges: cast iron hinges have the advantages of strong load-bearing capacity and low price, which are suitable for some occasions with not too high performance requirements. However, cast iron hinges are prone to rust and require regular maintenance and repair.
Aluminum alloy hinges: Aluminum alloy hinges have the advantages of light weight and corrosion resistance, which are suitable for some occasions with high requirements on weight. However, the weight-bearing capacity of aluminum alloy hinges is relatively weak.
Surface treatment
In order to improve the corrosion resistance and aesthetics of hinges, surface treatment is usually carried out on hinges. Common surface treatment methods include galvanization, chrome plating, spraying and so on.
Galvanized: Galvanized is a common surface treatment, which can form a layer of zinc on the surface of the hinge to prevent the hinge from rusting. The price of galvanized hinges is relatively low, and it is suitable for some occasions with not too high requirements for surface treatment.
Chrome plating: Chrome plating can make the hinge surface more smooth and beautiful, but also has a certain degree of corrosion resistance. The price of chrome-plated hinges is relatively high, which is suitable for some occasions with high requirements on appearance.
Spraying: spraying can form a layer of protective film on the surface of hinges to improve the corrosion resistance and aesthetics of hinges. The color of spraying hinges can be selected according to the need, which is suitable for some occasions with requirements on color.
V. Consider the installation and maintenance of hinges
Installation
Heavy industrial door hinges are usually installed by welding, bolting, etc. Different installation methods have different advantages. Different installation methods have different advantages and disadvantages, and need to be selected according to the actual situation.
Welding: Welding is a stronger installation method, which can make the hinges closely connected with the door and the door frame and improve the stability of the door. However, welding requires specialized equipment and technology, the installation cost is higher, and once the installation is completed, it is difficult to adjust and replace.
Bolt connection: Bolt connection is a more flexible installation method, which can make a certain gap between the hinges and the door and the door frame, which is convenient for adjustment and replacement. However, the solidity of bolt connection is relatively weak, and you need to check and tighten the bolts regularly to ensure the safety of the door.
Maintenance
In order to extend the service life of the hinges of heavy-duty industrial doors, it is necessary to carry out regular maintenance on the hinges. Maintenance mainly includes cleaning, lubrication and inspection.
Cleaning: Regularly clean the dust and dirt on the hinge surface to keep the hinge clean and beautiful.
