SFRC Manhole Covers

Overview

Steel Fibre Reinforced Concrete (SFRC) Manhole covers are a frame and sewer lid combo that are placed over the manhole to ensure that no object falls inside. These SFRC manhole covers need to be sturdy and well-fitted to eliminate the risk of accidents on the roads. RCC Manhole covers are able to tolerate heavy loads, resist corrosion, and have a long life as compared to traditional Iron Manhole covers.

We at Shubh Sanskar, manufacture inspection Manhole Covers and frames that are suitable for use in various areas from residential to commercial to industrial environments. These chamber covers are manufactured in various load capacities like Light Duty (LD -2.5), Medium Duty (MD- 10), Heavy Duty (HD-20) and Extra-Heavy Duty (EHD -35) catering to all types of your project needs. We manufacture SFRC Manhole Covers using high quality concrete of M30 Grade with appropriate reinforcement as specified in IS 12592 so that all our manhole covers and frames can withstand substantial loads and harshest environments, ensuring long life and sustainability.

Manhole covers are primarily used to provide underground access of manhole systems, sewage systems, manhole drainage systems, telecommunication cables, and gas pipelines ensuring that proper maintenance of these underground lines can be done.

Types of SFRC Manhole Covers

SFRC manhole covers have a wide application ranging from residential to industrial use. To cater to these varied requirements, a range of cement chamber covers are available. Here is the list of various types of concrete manhole cover and frame with their applications:

Light Duty: light duty chamber covers are designed to handle lighter loads and are suitable where there is less traffic movement. These covers can handle loads up to 2.5 tons. They are appropriate for the use in residential or commercial complexes, sidewalks, and the areas with rare and light motor traffic.
Medium Duty: these sewer lid covers can handle medium traffic load and low weight vehicles. Medium Duty Concrete Manhole Cover and frame can take load up to 10 tons. They are suitable for use in car parking areas, service lanes, and the areas with medium-duty vehicular traffic.
Heavy Duty: heavy duty manhole covers are designed for the use in area with heavy loads and regular traffic. These sfrc manhole covers are capable of withstanding load of 20 tons, this makes it perfect for use in highways, bus stands, parking lots with heavy duty vehicle movement, commercial areas, and industrial zones.
Extra Heavy Duty: Extra heavy duty manhole covers as the name suggest can withstand huge weight and movement. These sewer manhole cover and frames can withstand weights up to 35 tons. They are suitable for use in port areas, godowns, airports, factories/industries where extra heavy goods are frequently transported, and other places where movement of heavy vehicles is high.
