Spring optical's Assemble SMC Manhole is made of Sheet Molding Compound(SMC) material with high material strength and climate-stability performance, while the total weight is 1/10 of traditional concrete material. By reducing the installation time, less people and equipment required, total EPC cost will be reduce.

Our Manhole use a unique "Knock-Down"^TM design, which means knock down into panels while delivering and assemble at the destination, the shipping space will be 1/4 of traditional prefabricated manhole – it means total shipping & logiest will be reduce 3/4. Pre-drilled SMC panel already preserved at each side of manhole, can be easily knock out for any requirement during cabling. It saves the time and cost to drill holes at site.

Advantage：

1. Assemble part light, panel per 15.1kg,easy to install

2. Knock-down package and assemble at site, save transportation cost

3. Comparing to precast concrete or brick-manhole, installation time is much shorter, only one-day.

4. Corrosion resistance and low water absorption rate( less than 0.5%)

5. High and low temperature application(-80℃ - 150℃)

6. Non-conductive
