A manhole cover is an essential component of urban infrastructure. In addition to protecting access to underground drainage systems, it also plays a crucial role in ensuring road user safety. Choosing a high-quality manhole cover is vital to preventing accidents, especially on high-traffic roads.

The Importance of High-Quality Manhole Covers for Road Safety

Accidents caused by weak or improperly installed manhole covers can be extremely dangerous. A cracked or displaced cover can cause vehicles to lose control, leading to serious accidents. Therefore, selecting a manhole cover made from strong and durable materials is essential for governments and infrastructure managers.

Manhole covers made of Bulk Molding Compound (BMC) offer an ideal solution due to several advantages over traditional materials like cast iron. BMC is more resistant to corrosion, lighter in weight, and not easily stolen since it has no resale value as scrap metal. As a result, the risk of open holes due to manhole cover theft can be significantly reduced.

BMC Design and Thickness for Optimal Protection

BMC manhole covers are designed with various specifications to accommodate different load requirements. Below are some available specifications:

• BMC Rounded: With a thickness of 60 mm and an outer diameter (OD) of 800 mm, this type weighs approximately 43 kg per unit, making it strong enough to withstand light to medium vehicle loads.

• BMC Square: Available in two sizes: 300 x 300 mm with a thickness of 30 mm (weighing 15 kg) and 600 x 600 mm with a thickness of 40 mm (weighing 35 kg). Suitable for pedestrian areas to light vehicle traffic zones.

• Ring BMC Rounded: With a thickness of 90 mm and an OD of 975 mm (BB 810 mm), this type weighs approximately 30 kg and can be used as a complementary component for manhole covers in various environments.

In addition to thickness and dimensions, BMC manhole covers are designed to comply with EN 124 (Europe) and AS3996 (Australia) standards, which classify products based on load class, ranging from pedestrian use to heavy vehicles. This ensures that each manhole cover is selected according to its load-bearing requirements, maintaining both safety and reliability.

BMC manhole covers are the best choice for enhancing urban infrastructure safety and durability. With advantages such as high durability, lighter weight, and resistance to corrosion and theft, these covers provide an ideal solution for various needs. In addition to the available specifications, Origa Mulia also offers custom-sized manhole covers, ensuring that customers can obtain non-standard sizes if required. With BMC manhole covers, urban drainage security and reliability are optimally ensured.
