SMC (Sheet Moulding Compound)Composite Manhole Covers, possess great features as Lightweight, Non- condactive, UV protected, Non-corrosive, Anti-slip, No scrap value,Sealable and Lockable etc. Hence, SMC Composite Manhole Cover has become the best alternative to traditional steel and iron covers.
The strength to weight ratio of SMC Composite Manhole Cover is much higher than other materials. That means the strength of SMC Composite Manhole Covers is higher even with lesser weight. SMC Composite Manhole Cover's weight can amount to a 65% weight saving over traditional cast iron or Concrete equivalents.
SMC Composite Manhole Cover is a thermoset material (non reversible and cannot be melted) and not a thermo plastic (reversible and can be melted). The non reprocessability protects it from theft and extreme sunlight does not soften the material.Hence, SMC Composite Manhole Cover is a suitable manhole cover in extreme environments.
SMC Composite Manhole Cover with high strength and lightweight with not only minimizes the risk of failure when installed but reduces the likelihood of breakages in transit and while off-loading.
There is a growing trend towards products that involve less risk in manual handling, where the deadweight of the casting or concrete is considered a potential risk during installation and actual handling.
SMC Composite Manhole Covers are flexible and do not disintegrate into pieces due to excess load bearing imparted on the cover, accidents on roads are avoided as the chambers are not left open even in case of cracking of cover.
Another unique feature of SMC Composite Manhole Covers is available in any other colours specified by clients.
