There are many types of concealed hinges, and there are different types through different ways of classification. In the field of industrial equipment. The use of hidden hinges is very common. In particular, they are widely used among electrical cabinets, network cabinets, server racks, and other equipment.

In the following, I will introduce the concept of concealed hinges and the different ways of classifying them from the perspective of what are the types of concealed hinges


What is a concealed hinge?

First, let’s understand what a concealed hinge is. I have covered this issue many times in other articles. The concealed hinges I am talking about here are for the industrial sector, as opposed to commercial hinges. For example, concealed hinges are installed on doors in buildings, furniture, etc.

IHINGES is a manufacturer specializing in hinges for doors used on industrial equipment. We have many years of experience in the development and production of industrial hinges. Our factory is located in Dongguan, Guangdong, China. Dongguan is known as a global manufacturing city. With a very complete industrial supply chain, product development and production are fully guaranteed. And it is a coastal city, so it is more convenient to export.

In the following, I will introduce what are the types of hidden hinges. Mainly from the material, structure, and installation method to divide.

What are the types of concealed hinges?

Concealed hinges used in industrial equipment are generally simple in structure, diverse in material, and simple in installation. These hinges are widely used in electrical cabinets, network cabinets, server racks, and other equipment. There are also some other emerging fields. For example, in the field of new energy. At present, among our customers, more and more enterprises come from the new energy field.

These hinges are somewhat less load-bearing than heavy-duty door hinges. After all, they are mainly installed on some lightbox equipment doors.

Types of concealed hinges: Material

In terms of material, we can classify three categories: iron, stainless steel, and zinc alloy.

Concealed hinges made of iron are generally used in indoor environments. The surface of iron hinges is protected by a layer of surface treatment such as electroplating, electrophoresis, or painting. These are used to increase the corrosion resistance of iron hinges.

Stainless steel is available in 304 and 316, which are the two most widely used materials, especially 304 stainless steel. The hinges made of stainless steel can be used both indoors and outdoors. Because this stainless steel industrial hinge has good anti-corrosion properties, there is a self-repair function.

Zinc alloy hinges also need a layer of protection on the surface. Electroplating, electrophoresis, or spraying on the surface of zinc alloy can give a very beautiful product. Concealed hinges made of zinc alloy have very good plasticity. The dimensions can be very precise. However, the use of these materials for the production of concealed hinges is relatively rare.

Types of concealed hinges: Structure

The structure is a major feature of concealed hinges. A hidden industrial hinge is installed inside the industrial cabinet, it needs to avoid some door and door frame structures. That’s why its structure is designed to be more complicated. The hinge block structure of this type of hinge generally needs to be bent to make room to avoid the structure inside the door.

Our most common structure is the U-shaped one, which allows the hinge to be well-installed inside the box. And it allows the door to open to the maximum angle. Other structures are more or less the same, and more often the structure of hidden hinges is designed according to the specific structure of the equipment door.

And they are often designed to be removable, mainly to facilitate the installation of hinges.

Types of concealed hinges: Installation method

The different ways of installation can also be classified as hidden hinges. There are two main types of mounting methods, one is bolt mounting and the other is welding mounting. I often talk about these two mounting methods in other articles.

The bolt-on method allows for easier maintenance. When the hinge needs to be replaced, the bolt can be quickly removed and replaced. However, it requires a hole to be cut and a screw to be installed.

The welded installation method allows the hinges to be welded directly to the door frame. There is no need to cut holes and use bolts. But it is more troublesome when replacing.

Types of concealed hinges: Summary

Through the above introduction, we can know the types of concealed hinges can be divided by their material, structure, and installation method. More often than not, we prefer to customize hinges for the actual equipment of our customers.
