FRP & LDPE MANHOLE COVERS & GRATINGS

FRP (Fiber Reinforced Plastic) and LDPE (Low-Density Polyethylene) manhole covers and gratings are alternative materials used in infrastructure systems for access to underground utilities, similar to cast iron and ductile iron covers and gratings.

Here's a brief overview of each material:

 

FRP Manhole Covers & Gratings: FRP is a composite material made of a polymer matrix reinforced with fibers such as fiberglass. FRP manhole covers and gratings are lightweight yet durable alternatives to traditional metal covers. They offer advantages such as corrosion resistance, UV resistance, and non-conductivity, making them suitable for various environments, including coastal areas, chemical plants, and wastewater treatment facilities. FRP covers and gratings are available in various sizes, shapes, and load-bearing capacities to suit different applications.

 

LDPE Manhole Covers & Gratings: LDPE is a type of thermoplastic polymer known for its flexibility, low density, and chemical resistance. LDPE manhole covers and gratings are lightweight, easy to handle, and resistant to corrosion, chemicals, and weathering. They are often used in applications where weight is a concern or where there is a need for non-metallic materials to prevent theft or corrosion issues. LDPE covers and gratings are commonly used in pedestrian areas, parks, and residential neighborhoods.

WHY CHOOSE LDPE & FRP COVERS?

  • Consistent Quality: Made using automatic machines, ensuring consistent quality and finish

​

  • High Strength: Made of high-strength fiber, providing a loading capacity of 3 tons even in commercial and small sizes starting from 10 x 10.

​

  • Cost Effective: A low-priced substitute compared to metal-based covers, with prices lower by 35% to 40%.

​

  • Quick Production: Machine-made with high production rates, allowing huge orders to be fulfilled in relatively lower lead time.

​

  • Anti Theft: Scrap value is almost zero, reducing the risk of theft.
