Product Description

1 Product Name: EN 124 D400 composite manhole covers

2 Introduction

What is SMC?

SMC is the short form of Sheet Moulding Compound. It is composed of resin, fiberglass and other chemical polymer. This is a raw material for mold pressing.

The core is chopped strand and unsaturated polyester resins paste that are covered by LDPE&HDPE sheet. With a thickness of 3mm-6mm, 600mm-1200mm width and is packed in rolls or boxes.

During production, to cut, weigh the raw material and then put it into a mould opening. After a high pressure and temperature preservation for set time. Final product is finished and will be transported to next working station.

SMC Manhole Cover in EN 124 with A15+, B125, C250, D400, E600, F900  

3 Product features

1. Against theft ---SMC manhole cover is non-metallic, non-conductive and non-sparking. It has no value of recycling, thus completely solving the problems caused by theft.

2. High load capacity ---Its main components are fibreglass and unsaturated resin. Existing moulds load capacity are A15, B125, C250, D400, E600. 

3. Free design---Sucs as Color, Logo, Panel, Load and Dimension can be desigened according to the requirements of customer. 

4. Long life ---Minimum lifespan of 30 maintenance free years.

5. Well sealed ---It can be used hermetically, and effectively prevent those poisonous gases leaking out from cesspool. Well sealled, no noise pollution or rebound.

6. Good wear and corrosion resistance ---It will never rust because it has good wear and corrosion resistance.

7. High and low temperature resistance ---Excellent insulator against heat ( from-40°C~200°C)

8. Lighter weight and more competitive price--- the weight of composite manhole cover especially SMC manhole cover is lighter. The composite manhole cover is more convenient to transport, install and repair.
