Understanding ​​Cast Iron Trench Grates Vs. Plastic Trench Grates

You might be trying to choose between cast iron trench grates versus plastic trench grates.

Many of the customers of the trench grate store need help in selecting the right material for the trench drain systems. In this post, let’s explore some of the primary differences between cast iron trench grates and plastic trench grates. That way, you can make the best decision for your needs.

Plastic Trench Grates Vs. Cast Iron Trench Grates

Cast Iron Grates

Cast iron trench grates come from molded cast iron bars. At The Trench Grate Store, we offer cast iron grates with H-20 load ratings and higher. These are excellent for semi-trucks, heavy construction equipment and more.

Plastic Grates

Plastic grates are typically not made to stand up to heavy loads. There is a reason that grates are often made with cast iron, strong polymers, or steel instead of stone or plastic.

The Benefits Of Cast Iron Grates

Cast iron grates are excellent for loading docks, parking garages, roadways and other areas in which there is heavy traffic.

Because of the H-20 or higher rating, they are safe and effective. Many people use cast iron grates for shopping centers, promenades, walkways and more. That’s not to mention their use in public works like roadways and parking lots.

The Benefits Of Plastic Trench Drain Grates

Frankly, The Trench Grate Store does not offer plastic trench drain grates. The primary reason for that is because we don’t see a lot of advantages for the material. It’s not particularly strong, durable nor sanitary.

It also doesn’t have great aesthetic qualities. Perhaps the only benefit is that it is somewhat less expensive in the short term. But if you’re interested in more of a long term investment, then we don’t suggest using plastic trench drain grates.
