The door frame, commonly known as the door pocket, is often used for fixing, corner protection and decoration of the door leaf to protect the door from scratch, corrosion, damage and dirt. At present, with the improvement of people's requirements for the quality of life, personal aesthetic needs have increased to a greater extent. How to design and make the commonly used door pocket

一、不锈钢门套做法

1、 Stainless steel door cover

01.不锈钢门套有两种样式

01. There are two styles of stainless steel door pocket

一种是垂直与水平面成45度角的形式，另一种是垂直与水平面垂直安装。建议采用后者。前者有时需要焊接和碰撞，非常麻烦，效果不好。常用的不锈钢板分为201型和304型。事实上，成分是不同的。304的质量稍好一点，但价格较高。201有点差，大型商场或写字楼需要304不锈钢来满足需求。板的厚度也不同，一般0.6就足够了。

One is the form of 45 degree angle between vertical and horizontal plane, and the other is vertical and vertical installation with horizontal plane. The latter is recommended. The former sometimes needs welding and collision, which is very troublesome and the effect is not good. Commonly used stainless steel plates are divided into 201 and 304 types. In fact, the composition is different. The quality of 304 is a little better, but the price is higher. 201 is a little poor. Large shopping malls or office buildings need 304 stainless steel to meet the demand. The thickness of the plate is also different, generally 0.6 is enough.

02.不锈钢门套的表面处理：板的表面处理也分为镜面和油膜刷。一般来说，镜面不锈钢不推荐用于商业装饰。油膜拉伸更好（即许多吸油烟机使用的材料）。

02. Surface treatment of stainless steel door pocket: the surface treatment of plate is also divided into mirror and oil film brush. Generally speaking, mirror stainless steel is not recommended for commercial decoration. The oil film is stretched better (i.e. the material used in many range hoods).

03.基本生产不锈钢门套9%的木材可用作门套衬里。如果砌砖工人熟练，这一步可以省略，可以直接使用不锈钢门框。

03. Basically produce stainless steel door pocket, and 9% of the wood can be used as door pocket lining. If the bricklayer is skilled, this step can be omitted and the stainless steel door frame can be directly used.

04.不锈钢门套的测量：由于一般商业装修数量较多，商家需要上门测量。此时测量需要小心准确，测量结果需要准确到毫米。

04. Measurement of stainless steel door pocket: due to the large number of general commercial decoration, businesses need door-to-door measurement. At this time, the measurement needs to be careful and accurate, and the measurement result needs to be accurate to mm.

05.不锈钢门套加工选择店内使用的折弯机，确定款式，协商价格。人们会上门测量尺寸，而且处理速度非常快。

05. For the processing of stainless steel door pocket, select the bending machine used in the store, determine the style and negotiate the price. People will come to the door to measure the size, and the processing speed is very fast.

二、不锈钢门套生产质量标准。

2、 Production quality standard of stainless steel door pocket.

1.所有黑钛不锈钢门框的落料一定要准确，部件长度的允许偏差为1mm。

1. The blanking of all black titanium stainless steel door frames must be accurate, and the allowable deviation of component length is 1mm.

2.切割前要检查不锈钢门框是否平直，否则需要调直。

2. Before cutting, check whether the stainless steel door frame is straight, otherwise it needs to be straightened.

3.焊接时，焊条或焊丝应与焊接材料相适应，不锈钢门框的焊接材料品种应有出厂合格证。

3. During welding, the welding rod or wire shall be compatible with the welding material, and the variety of welding material for stainless steel door frame shall have factory certificate.

4.焊接时，不锈钢门框的位置一定是正确。

4. When welding, the position of stainless steel door frame must be correct.

5.焊接时，不锈钢门框之间的焊点应牢固、充足，焊缝表面焊缝应均匀。焊缝不得有咬边、裂纹、裂纹、浮渣、焊块、烧穿、电弧划伤、弧坑和针状气孔，焊接区域不得飞溅。

5. During welding, the welding joints between stainless steel door frames shall be firm and sufficient, and the welds on the weld surface shall be uniform. The weld shall be free of undercut, crack, crack, scum, welding block, burn through, arc scratch, arc pit and needle pore, and the welding area shall not splash.

6.不锈钢门框焊接后，应清理干净焊渣。

6. After the stainless steel door frame is welded, the welding slag shall be cleaned.

7.不锈钢门框焊接组装后，用手持式机器进行适当的打磨和抛光，使其外观光滑整齐。

7. After the stainless steel door frame is welded and assembled, it shall be properly polished and polished with a hand-held machine to make its appearance smooth and tidy.

8.用镀锌角钢连接筒体

8. Connect the cylinder with galvanized angle steel

9.与槽钢、角铁连接

9. Connection with channel steel and angle iron

10.用自攻螺钉将9%钢板与槽钢连接

10. Connect 9% steel plate and channel steel with self tapping screws
