The Different Types of Trench Drain Grates

The Different Types of Trench Drain Grates

We all see grates on a daily basis when walking, driving, or even riding a bike down the street. It’s easy to take them for granted, but without drainage grates, drainage systems couldn’t work, leaving our streets flooded with excess water. Each grate is designed to suit specific areas. Understanding the different types of trench drain grates is essential in choosing the right type for the job. Let’s look at each of these types.

Regulations for Drainage Grates

Because drainage grates are found in commercial and public places, there are laws and requirements in place to keep the public safe—namely, the ADA standards and load and class requirements.

ADA Requirements

The Americans with Disabilities Act (ADA) created specific standards for drainage grates to ensure people with disabilities aren’t hindered should a grate be in their path. For instance, per these requirements, things like holes in the grates must adhere to a safe size. This prevents wheelchairs or canes from getting stuck.

Loads and Classes

Grates see high traffic, including from cars and trucks. Every grate is classified into a load class standard for the safety of the roads and those on the roads.

Trench Drain Grates

A trench drainage system is an elongated drainage system embedded in the ground and covered with a grate for draining. They’re designed to control excess surface water. Three common types you’ll often see are standard, heel proof, and decorative.

Horizontal, Vertical, and Diagonal Alignment

The holes in each drain grate are created with either a horizontal, vertical, or diagonal alignment, with the exception of decorative grates, which vary in design. Let’s look at how each functions and serves its purpose.

The different types of trench drain grates are built with approved materials, such as cast iron, polymer, galvanized steel, or ductile iron, and—as mentioned—must meet ADA and load class requirements.
