SFRC Manhole
Cover & Frame

"Strength Engineered into Every Fibre."

Igloo's SFRC (Steel Fiber Reinforced Concrete) Manhole Covers are engineered with a high-performance concrete matrix reinforced with precisely dosed steel fibers. This technology eliminates the need for traditional rebar, reducing weight while dramatically increasing tensile strength and crack resistance. Unlike cast iron covers, our SFRC units are non-conductive, corrosion-free, theft-deterrent (no scrap value), and suitable for Tamil Nadu's aggressive environmental conditions — from coastal salt air to heavy monsoon flooding.

Anti-Theft by Design

Unlike cast iron, SFRC has no metal scrap value. Virtually eliminates theft — a major problem with conventional iron covers in Indian cities.

Electrical Safety

Non-conductive material is safe near electrical cables, transformer stations, and telecom ducts — mandatory in many urban utility specifications.

Corrosion Proof

Zero rusting even in Tamil Nadu's coastal saline environments and high-humidity monsoon conditions. Maintenance-free for 30+ years.

High Load Capacity

Heavy Duty Class C withstands 40-tonne axle loads — suitable for port roads, national highways, and heavy industrial facilities.

Lightweight vs. Cast Iron

30% lighter than equivalent cast iron covers, making installation faster, safer, and more ergonomic — reducing labour costs significantly.

IS 12592 Certified

Tested and certified to Bureau of Indian Standards IS 12592:2002 — accepted in all TNUIFSL, TWAD, CMWSSB, and municipal projects.
