SMC Drainage Manhole Cover Round D400 Access Cover 25 Tons Load Capacity

Environmentally Friendly SMC Manhole Cover for Drainage, Round D400 Certified

Product Description:

This SMC manhole cover is crafted from high-strength composite materials, offering exceptional durability and corrosion resistance. Its lightweight design ensures easy installation and maintenance. Ideal for urban infrastructure, it complies with EN124 standards and supports various load classes. The anti-slip surface and customizable options make it suitable for diverse applications.

Product Details:

Certified to meet EN124 D400 standards, the manhole cover is capable of withstanding heavy loads up to 40 tons, making it suitable for installation in fast lanes, toll stations, expressway shoulders, and bridge access roads. Its circular shape is ideal for high-speed environments because it distributes stress uniformly and prevents the cover from being dislodged by tire pressure or heavy vehicles.

One of the key advantages of this product is its resistance to environmental degradation. It is immune to rust, does not absorb water, and resists chemical corrosion caused by de-icing salts, fuels, oils, or acid rain. Unlike metal covers that require periodic repainting or replacement due to oxidation, this composite cover maintains its physical integrity and appearance even after years of outdoor exposure.

The surface is molded with a high-friction texture, enhancing skid resistance to reduce the risk of accidents for both vehicles and maintenance personnel. In rainy or icy conditions, the anti-slip design plays a vital role in road safety. Additionally, the cover can be fitted with a sealing ring that provides a watertight barrier, preventing runoff from entering underground systems and causing flooding.

Despite its heavy-duty performance, this manhole cover is up to 60% lighter than ductile iron alternatives. This significantly reduces installation time, transportation costs, and workplace injuries due to manual handling. A single worker can lift the cover using simple tools, making it ideal for quick roadside maintenance and emergency repairs.

Security and theft prevention are also top priorities. Because the SMC material contains no scrap value, the risk of theft is virtually eliminated. The cover can be customized with locking mechanisms, hinge designs, and municipal logos. Color options and embedded reflective strips are also available for night-time visibility.

Whether used in national highway systems or local road upgrades, this SMC manhole cover offers outstanding lifecycle value. It requires minimal maintenance, enhances safety, and supports environmental sustainability goals by reducing the carbon footprint associated with manufacturing and logistics.

Ideal for civil engineering contractors, highway maintenance departments, and infrastructure developers, this product delivers on all fronts: performance, safety, longevity, and cost-efficiency. It represents a forward-looking solution for modern road networks seeking to upgrade from outdated materials to smart, sustainable alternatives.
