電動伸縮棚在日常生活中應用廣泛，但是市面上的品種繁雜，質量不一。很多人往往不知道該如何選擇。下面分享的幾點，可以在一定程度上幫助我們正確選擇推拉棚。

Electric telescopic sheds are widely used in daily life, but there are a variety of varieties and varying quality on the market. Many people often don't know how to choose. The following points shared can help us to choose the right sliding shed to a certain extent.

一、從伸縮棚頂部的架子判斷。

1、 Judging from the frame at the top of the telescopic shed.

棚架需要合理的距離來滿足斜拉筋的數量，質量差的伸縮棚斜拉筋會少，距離太長。偷工減料的結果是結構承載力嚴重不足，結構簡單變形，使用壽命嚴重降低。抵御不了風，隨時有倒塌的危險。

The top shelf requires a reasonable distance to meet the quantity of diagonal braces. Poor quality expansion sheds will have fewer diagonal braces and a too long distance. The result of cutting corners and materials is a serious lack of structural bearing capacity, simple deformation of the structure, and a serious reduction in service life. Unable to withstand the wind, there is a risk of collapse at any time.

二、彈力架長度合理。

2、 The length of the elastic frame is reasonable.

彈性框架長度影響柱的穩定性，從而影響整體穩定性。

The length of the elastic frame affects the stability of the column, thereby affecting the overall stability.

三、螺栓的材料

3、 Material of bolts

螺栓是連接立柱和頂架的鉸鏈，一般單獨使用加厚管。質量差的是用邊角料。螺栓是車架受力的關鍵部位，材質尤為重要，直接影響牢固程度。邊角料的使用導致危險壽命短。

The bolt is a hinge that connects the column and the top frame, usually using thickened pipes separately. Poor quality is achieved by using leftover materials. The bolt is a key part of the frame under stress, and the material is particularly important, which directly affects the firmness. The use of scraps leads to a short hazardous lifespan.

四、布料的材料。

4、 The material of the fabric.

電動伸縮棚選用PVC網布，抗拉強度強，使用壽命約5-10年。而差的伸縮棚是用普通廉價油補充的，年限的約束大概短1-2年。

The electric telescopic shed is made of high-quality PVC mesh fabric with strong tensile strength and a service life of about 5-10 years. The poor telescopic shed is supplemented with ordinary cheap oil, and the lifespan constraint is about 1-2 years short.

五、制造技術

5、 Manufacturing Technology

制造時通常先制造模具，零件長度普通，沖壓方向普通，開口正常，受力均勻，長度普通，無扭轉。質量差異是:長度不符和打孔錯誤。沖壓誤差，簡單斷裂，長度誤差，扭轉。頂篷活動需要統一驅動所有附件。如果配件不對稱，就容易產生各種扭轉，不容易拉動，簡直損壞配件，降低壽命。

When manufacturing, molds are usually made first. The length of the parts is ordinary, the stamping direction is ordinary, the opening is normal, the force is uniform, the length is ordinary, and there is no torsion. The quality difference is: inconsistent length and incorrect punching. Stamping error, simple fracture, length error, torsion. The roof activity requires a unified drive for all accessories. If the accessories are asymmetrical, it is easy to produce various twists, not easy to pull, and it is simply damaging the accessories, reducing their lifespan.
