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、不銹鋼門套做法

1、 Stainless steel door cover

01.不銹鋼門套有兩種樣式

01. There are two styles of stainless steel door pocket

一種是垂直與水平面成45度角的形式，另一種是垂直與水平面垂直安裝。建議采用后者。前者有時需要焊接和碰撞，非常麻煩，效果不好。常用的不銹鋼板分為201型和304型。事實上，成分是不同的。304的質量稍好一點，但較高。201有點差，大型或寫字樓需要304不銹鋼來滿足需求。板的厚度也不同，一般0.6就足夠了。

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.不銹鋼門套的表面處理：板的表面處理也分為鏡面和油膜刷。一般來說，鏡面不銹鋼不用于商業裝飾。油膜拉伸更好（即許多吸油煙機使用的材料）。

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.基本生產不銹鋼門套9%的木材可用作門套襯里。如果砌磚工人熟練，這一步可以省略，可以直接使用不銹鋼門框。

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.不銹鋼門套的測量：由于一般商業裝修數量較多，商家需要上門測量。此時測量需要小心準確，測量結果需要準確到毫米。

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.不銹鋼門套加工選擇店內使用的折彎機，確定款式，協商。人們會上門測量尺寸，而且處理速度非常快。

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、不銹鋼門套生產質量標準。

2、 Production quality standard of stainless steel door pocket.

1.所有黑鈦不銹鋼門框的落料一定要準確，部件長度的允許偏差為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.切割前要檢查不銹鋼門框是否平直，否則需要調直。

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

3.焊接時，焊條或焊絲應與焊接材料相適應，不銹鋼門框的焊接材料品種應有出廠合格證。

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.焊接時，不銹鋼門框的位置一定是正確。

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

5.焊接時，不銹鋼門框之間的焊點應牢固、充足，焊縫表面焊縫應均勻。焊縫不得有咬邊、裂紋、裂紋、浮渣、焊塊、燒穿、電弧劃傷、弧坑和針狀氣孔，焊接區域不得飛濺。

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.不銹鋼門框焊接后，應清理干凈焊渣。

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

7.不銹鋼門框焊接組裝后，用手持式機器進行適當的打磨和拋光，使其外觀光滑整齊。

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.用鍍鋅角鋼連接筒體

8. Connect the cylinder with galvanized angle steel

9.與槽鋼、角鐵連接

9. Connection with channel steel and angle iron

10.用自攻螺釘將9%鋼板與槽鋼連接

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