伸缩棚在日常生活中应用广泛，所以里的品种繁杂，质量不一。很多人面对的是鱼龙混杂的，往往不知道该如何选择。下面小编就为我们分享五点，可以在一定程度上帮助我们正确选择推拉棚。

Retractable sheds are widely used in daily life, so there are many varieties and different quality in shopping malls. Many people are faced with a mixed market, often do not know how to choose. The following editor will share five points for us, which can help us choose the sliding shed correctly to a certain extent.

要点一:从伸缩棚顶部的架子判断。

Point 1: judge from the shelf on the top of the telescopic shed.

棚架需要合理的距离来满足斜拉筋的数量，质量差的伸缩棚斜拉筋会少，距离太长。偷工减料的结果是结构承载力严重不足，结构简单变形，使用寿命严重降低。抵御不了风，随时有倒塌的危险。

The top shelf needs a reasonable distance to meet the number of diagonal braces. The diagonal braces of the telescopic shed with poor quality will be less and the distance is too long. The result of cutting corners is that the bearing capacity of the structure is seriously insufficient, the structure is simple and deformed, and the service life is seriously reduced. Unable to resist the wind, there is a danger of collapse at any time.

要点二，弹力架长度合理。

Second, the length of the elastic frame is reasonable.

弹性框架长度影响柱的稳定性，从而影响整体稳定性。

The length of elastic frame affects the stability of columns, thus affecting the overall stability.

要点三:螺栓的材料

Key point 3: bolt material

螺栓是连接立柱和顶架的铰链，一般单独使用加厚管。质量差的是用边角料。螺栓是车架受力的关键部位，材质尤为重要，直接影响牢固程度。边角料的使用导致危险寿命短。

The bolt is the hinge connecting the column and the top frame, and the thickened pipe is generally used alone. Those with poor quality are leftover materials. Bolts are the key parts of the frame, and the material is particularly important, which directly affects the firmness. The use of leftover materials leads to short dangerous life.

要点四:布料的材料。

Point 4: material of cloth.

OK伸缩棚选用PVC网布，抗拉强度强，使用寿命约5-10年。而差的伸缩棚是用普通廉价油补充的，年限的约束大概短1-2年。

OK telescopic shed adopts high-quality PVC mesh, with strong tensile strength and service life of about 5-10 years. The poor telescopic shed is supplemented by ordinary cheap oil, and the age constraint is about 1-2 years shorter.

要点五:制造技术

Key point 5: Manufacturing Technology

济南伸缩棚制造时通常先制造模具，零件长度普通，冲压方向普通，开口正常，受力均匀，长度普通，无扭转。质量差异是:长度不符和打孔错误。冲压误差，简单断裂，长度误差，扭转。顶篷活动需要统一驱动所有附件。如果配件不对称，就容易产生各种扭转，不容易拉动，简直损坏配件，降低寿命。

Jinan telescopic shed is usually manufactured with molds first. The length of 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 wrong punching. Stamping error, simple fracture, length error, torsion. Roof movement requires all accessories to be driven uniformly. If the parts are asymmetrical, it is easy to produce various torsion, which is not easy to pull, and it simply damages the parts and reduces the service life.
