They not only prevent flooding after rain but also help avoid clogged sewers caused by waste. Have you ever wondered what materials are used to make manhole covers? Let’s explore this with Hòa Phát Furniture – Hòa Phát Group.

What is a Manhole Cover?

Before we get into the materials used for manhole covers, let’s first understand what a manhole cover is.

A manhole cover is an essential part of drainage systems and sewer networks. Its purpose is to cover and protect the manhole from blockages caused by excess waste. Additionally, it helps ensure the safety of pedestrians by preventing accidents when passing over manholes. In large projects and urban areas, manhole covers are crucial for ensuring effective drainage and preventing blockages caused by household waste and other debris.

Now that we've covered what a manhole cover is, let's move on to the materials used to make them. Read on for more information below.

Top Materials for Manhole Covers Today

Depending on the local conditions and specific needs of the area, manhole covers are made from different materials that meet both technical standards and quality requirements. Typically, manhole covers are made from materials that are durable and widely used in the area. Below, we’ll explore the materials that are highly regarded in manhole cover production.

Composite Manhole Covers

At the top of the list of materials for manhole covers is composite. This material is made by combining plastic with various additives and chemicals. This combination creates a highly durable material with great load-bearing capacity.

Specifically, composite is made from polyester, reinforced fiberglass fabric, crushed stone, Mepox, and other additives. After a series of chemical reactions, composite is created with high flexibility and durability.

With its durability and relatively low production cost, composite is one of the most preferred materials for contractors, especially in demanding projects like road construction and industrial zones. It is one of the top materials that meet the aforementioned requirements.

However, there are some drawbacks to composite manhole covers. Since they are made from plastic, their fire resistance is lower compared to other materials, and they cannot be recycled.

Stainless Steel Manhole Covers

Next on the list of the best manhole cover materials is stainless steel. Stainless steel is used for covering underground tanks, including water tanks, communication cable tanks, septic tanks, or any other type of underground tank.

Stainless steel manhole covers are durable, rigid, resistant to warping, deformation, and have good resistance to oxidation. They not only meet the basic functionality of a manhole cover but also offer an aesthetic appeal. Due to their high oxidation resistance, they maintain their integrity over time.

Steel Manhole Covers

Steel is a commonly used material in daily life. It is durable and relatively hard, making it ideal for manhole covers. Steel manhole covers are particularly durable when galvanized, which allows them to withstand harsh conditions effectively.

Another notable feature is that steel manhole covers are resistant to explosions, easy to drain, and clean. This is why steel is one of the most popular materials for manhole covers today.

Concrete Manhole Covers

Concrete manhole covers are also commonly produced by Hòa Phát Furniture – Hòa Phát Group and many other companies. Concrete is one of the first materials used for manhole covers. Despite being more affordable and easy to produce, concrete manhole covers are durable and provide reliable performance.

However, concrete is heavy, making it less suitable for large-scale projects due to its bulkiness and difficulty in transportation. This also makes maintenance and cleaning of concrete manhole covers more challenging.
