Time : 2022-07-04 Hits : 5

Side hung door refers to a door with hinges installed on the side of the door and opened inward (left inward, right inward) or outward (left outward, right outward). It is composed of door pocket, hinge, door leaf, lock, etc.


Single door and double door are terms in another classification system, and there is no contradiction between flat door and open door.

The Casement door  has single Casement door and double Casement door.

Single door means that there is only one door panel, one side is used as the door shaft, and the other side can be opened and closed, while double door has two door panels, each with its own door shaft, which can be opened in two directions.

The Casement door is divided into one-way opening and two-way opening

One way opening means that the door can only be opened in one direction (only pushed in or pulled out). Two way opening means that the door leaf can be opened in two directions (such as spring door).

The Casement door is divided relative to other opening methods, because the door also has mobile opening, upturning, roller shutter lifting, vertical lifting, rotary and so on.

Aluminum alloy bathroom Casement door is often referred to as Casement door in the market.


The profile and glass styles of aluminum doors can be divided into North and south. The north is mainly characterized by thick aluminum and calm style. The most representative is the grid style, and the most distinctive of the grid is tangge. The south is mainly characterized by various aluminum shapes and flexible styles. The most representative is the flower glass style. The more distinctive styles include lattice, ice carving, shallow carving, crystal shell, etc.

Classification of Casement door

Material classification

It can be divided into: solid wood door, composite solid wood door, molded door, etc.


Solid wood door: it has thick texture and good sound insulation effect, giving people a warm and soft feeling, but it is easy to deform.

Composite solid wood door: generally, fir is used as the core, pasted with high-density board, and then wrapped with a layer of solid wood on the surface, which is firm and not easy to deform.

Molded door: it is made of wooden fiber under high pressure of the machine, and the surface is easy to make various concave convex shapes.

Formal classification

It can be divided into: ordinary Casement door, door in door, child and mother door, composite door, etc.

Ordinary Casement door: it is a closed door opened by a single leaf.

Middle door: it has the advantages of both fence door and Casement door. The part of its outer door is fence door, and there is a small door behind the fence door. Opening the small door can be used for ventilation of the fence door, and closing the small door can be used as Casement door.

Child mother door: it is generally used in houses with large door frames, which not only ensures convenient access at ordinary times, but also allows large furniture to be moved in easily.

Compound door: also known as one frame and two doors, the front door is a fence door, and the rear door is a closed Casement door.

Selection of hardware for Casement door

The hardware used by doors with different opening and closing methods is different, and the common ones are Casement door hardware, sliding door hardware, folding door hardware, etc. Casement door is the most commonly used form of opening and closing, which is widely used in various places. Because the form of hardware on the hinge side is similar, the selection of hardware for Casement door is discussed from the aspect of door locking.

Common door lock forms

Common locking devices include single point door lock, multi-point door lock, door driver with safety lock hook, etc. compared with each other, they have their own advantages and disadvantages:

1. Single point door lock

The characteristics of the single point door lock are: the handle drives the oblique tongue, and the key drives the square tongue; Under normal conditions, only the oblique tongue plays a locking role. Rotating the key can stretch out the square tongue, which has the effect of security and theft prevention. The advantages of single point door lock are simple structure and convenient use; The disadvantages are also obvious. Due to the single point locking, the sealing performance is not good, and the door leaf cannot be prevented from deformation.

2. Multi lock point door lock

The common multi-point door lock can be divided into two types according to the structure: linkage door lock and door driver.

The lock body part of the linkage door lock is similar to the single point door lock. It adds a sliding rod at both ends of the lock body, and the sliding rod is connected with the connecting rod with the locking point. The door buckle plate and lock base are installed on the matching frame, so as to achieve the effect of multi-point locking.

Door drivers can also be divided into simple door drivers and door drivers with lock. Simple door drivers are used for indoor doors without anti-theft requirements, and can also be used for occasions requiring one-sided anti-theft, that is, only install the handle on one side. Door drivers with lock, that is, add a lock box with lock cylinder on the basis of simple door drivers, and rotate the key to fix the sliding rod to achieve the anti-theft function. The number of locking points can be further increased and the sealing performance can be enhanced by making the end of the sliding rod of the driver into a rack form and cooperating with the corresponding steering angle and connecting rod; If it is used with the diagonal pull rod, it can also realize the function of flat opening and lower suspension. Compared with the single point door lock, the multi-point door lock has obvious advantages: multi-point locking has good sealing performance, and can also make the force of the door frame and the door leaf more uniform, so as to effectively prevent the deformation of the door leaf.

3. Door lock with locking hook

The door lock with locking hook is to make one or more locking points into the form of locking hook on the basis of multi-point door lock, which greatly enhances the anti-theft performance on the basis of multi-point locking.

Selection of door lock

Different places have different requirements for the performance of doors, and appropriate door locks should be selected according to the actual situation. The state vigorously advocates building energy conservation. The Fifth Plenary Session of the 16th CPC Central Committee passed the proposal of formulating the 11th five year plan, and the first goal is to reduce energy consumption. Relevant departments are promoting the incorporation of the energy-saving standard system into national policies to improve the efficiency of the implementation of building energy-saving standards and implement the spirit of developing energy-saving buildings in the eleventh five year plan.

Generally, the opening and closing frequency of indoor doors is high, but the requirements for sealing performance are not high. The single point door lock with convenient operation can be selected.

The doors connecting with the outside world (such as balcony doors, corridor doors of hotels or offices, etc.) should try to choose multi-point door locks with good sealing performance, so as to improve the energy-saving effect of the building.

For some occasions with high requirements on anti-theft, the door lock with locking hook can be selected.
