Round manhole covers made of SFRC (Steel Fibre Reinforced Concrete), a composite material formed of concrete strengthened with steel fibres, are one type of manhole cover. These covers are appropriate for applications where a high load-bearing capacity is required since they are built to offer strength, durability, and resistance to large loads.
Compared to more conventional materials like cast iron, SFRC circular manhole covers provide a number of benefits. The cover's structural integrity is improved by the steel fibre reinforcement, which enables it to bear high traffic loads without breaking or cracking. Compared to cast iron covers, they also last longer and need less care.
The load ratings for these covers are normally A15 (light-duty), B125 (pedestrian), C250 (vehicle), D400 (truck), or higher. They are frequently utilised in a variety of infrastructure systems, such as utility trenches, drainage systems, sewage networks, and other access points.
Round SFRC manhole covers are offered in a variety of sizes and styles to meet the needs of various projects. They frequently have to lift knobs or keyholes for simple removal during repair or inspection tasks. To improve pedestrian and vehicle safety, these covers could also contain anti-slip surface coatings or designs.
