Die tydelike slootbedekkingsmateriaal is SMC. Hierdie materiaal is beter as HDPE en staal ens.
SMC characteristic:
1 inflaming retarding,
2 Hight mechanical strength
3 Ligte gewig
4 corrosion resisting
5 Lang lewensduur
6 High insulation
7 Arc resistance
8 anti-aging
According above characteristic, it is lighter than steel plate trench cover and it is easy to move. The weight is nearly to HDPE material trench cover. But SMC material trench cover is inflaming retarding and anti-aging. So our temporary trench cover can be used long time. When the trench cover age, the loading will change.
