How to distinguish the quality of the sliding shed? In fact, it can be seen from some details.
1. Judging from the shelf at the top of the sliding shed
The top shelf needs a reasonable spacing enough to support the number of diagonal braces. Poor quality sliding sheds will have fewer diagonal braces and the spacing is too large. The consequences of cutting corners are: the structure's load bearing capacity is seriously insufficient, it is easy to deform, and its lifespan is severely reduced. It cannot resist wind, and there is a risk of collapse at any time.
2.The length of the telescopic frame is reasonable
The length of the telescopic frame affects the stability of the column, which in turn affects the overall stability.
3.Material of bolt
The bolt is a link connecting the column and the top frame. Generally, a separate thick pipe is used. The poor quality is the use of corner waste. Latches are the key part of the structure's stress. The material is particularly important. It directly affects the firmness. The use of corner waste materials has a high risk and a short life.
4. Manufacturing process
In the production, the mold is usually made first, the parts are the same length, the hole positions are uniform, the holes are opened normally, the force is uniform, the length is consistent, and there is no torque. The poor quality is: the length is different, the punching deviation. Punching deviation, easy to break, length deviation, and torque. Canopy activities require the uniform driving of accessories. If the accessories are uneven, it is easy to generate various torques, it is not easy to pull, it is easy to damage the accessories and reduce the life.
5. Cloth materials
Good sliding sheds are made of high-quality PVC mesh fabric with strong tear resistance and a service life of about 5-10 years. The unsatisfactory push-pull shed uses ordinary low-cost oil supplements, and the service life is short about 1-2 years.
