The covers of cable ramp on the market mostly use PVC materials, that is polyvinyl chloride.
The main characteristics of PVC materials: low cost and easy to form.
Disadvantages: The material itself is unstable, high in hardness, and easy to break.
The high-quality wire ramp cover plate is made of ABS, which is one of the five major synthetic resins. Its impact resistance and pressure resistance are very good, and the finished product has good toughness and will not easily get broken.
In addition to checking the material of the ramp cover, it can also can be distinguished by the thickness of the cover.
The thickness of the high-quality cover can reach 0.7cm, and the thickness of the base support column can reach 1.8cm, and the appearance is delicate.
If the thickness of the cover is 0.3cm, the thickness of the support column of the base is 0.9cm, and the appearance is rough, it is a poor quality cover.
The second trick: check the connector
the connector rubber through the trunking, which mainly plays a supporting role. The connector on the market has an integrated connector and a splicing connector. The one-piece connector is stronger than the spliced connector, will not break, is durable, and is easy to use. Splicing connectors are mostly made of recycled materials, and the disadvantage is that they are easy to break.
The third trick: check the bottom
The main reason is the rubber particles at the bottom of the rubber cable trough. The new rubber has a smooth surface, a delicate touch, is not easy to disconnect, can carry a large weight, and has a long service life. On the contrary, it is old rubber, and the material is mostly waste tires recycled twice and three times. This kind of base is weak, and it is easy to break and scrap.
