Ábhar an chlúdaigh trinse sealadach - tréith ábhar SMC

Is é SMC an t-ábhar sealadach um chlúdach trinse. Is fearr an t-ábhar seo ná HDPE agus cruach srl.

SMC characteristic:

1 inflaming retarding,

2 Hight mechanical strength

3 Light weight

4 corrosion resisting

5 Long service life

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. Such as it can be from 500kgs to 300kgs or less.
