All You Need to Know About the Grated Trench System

Trench drain grates are among the most popular drainage systems available on the market. If you want to install a drainage system on a new property or upgrade an existing one, a grated trench system should top your list of options. This guide explores everything you would like to learn about trench grates to help you make an informed choice.

Grated Trench Systems in Brief

Trench drains are the most common drainage systems and consist of long, trough-like channels. These channels drive water away from a facility and have a linear-shaped grate cover. They ensure efficient drainage of stormwater and runoff on a property. The trench drain collects water and redirects it away from structures. Surface water and other liquids flow through the grated cover into the trench drain and away from the property. Different materials are used to make drain grates including cast iron, plastic, galvanized steel, stainless steel, FRP, ductile iron, black powder-coated steel aluminum, polymer concrete, brass and bronze. Each of these materials has its own qualities, pros and cons.

A grated trench system is versatile and can serve in several areas including:

Heavy Duty Industries: From airports, military facilities, docks and ports, refineries, warehouses, manufacturing facilities to transportation terminals grated trench systems can hold a lot of weight and help with drainage in these facilities.

Animal Facilities: There’s a lot of liquid waste created in farms, hospitals, and zoos and grated drain systems come handy in facilitating cleaning and maintenance.

Landscaping: You can use grated trench drains on parks, residential facilities, landmarks, and for fountains to facilitate groundwater drainage.

Food and Beverage Industries: From abattoirs, seafood markets, dairy farms to breweries and wineries, this is the perfect drainage system to keep these facilities clean and sanitary.

Education, Commercial, and Residential Locations: Facilities such as parking lots, commercial kitchens, gyms, bathrooms, swimming pools and playgrounds require effective drainage and grated trench drains work perfectly.

Automotive Industry: Facilities handling vehicles including dealerships, car washes, and gas stations and parking garages can benefit a lot from grated drains to stay clean and drain excess water.

Selecting the Right Grated Trench System

When installing a grated trench system, there are several things to consider:

Needs Assessment

You need to assess the drainage requirements for your property. Every facility has unique drainage requirements. For instance, a manufacturing facility will be keen to find the best drainage system for liquid waste. For landscaping purposes, for instance, you need a different system to allow efficient surface drainage. In one case, iron grates might work to accommodate heavy traffic in an industrial facility, but in another, stainless steel grates are perfect for enhancing aesthetics on a residential property. Choosing the drain system will also involve determining the flow rate. You have to consider who much fluid you expect the drain system to remove and how quickly.


When selecting the grates for your trench drains, you have to consider their visual appeal. If you want to drain your landscaping, you should go for easily customizable grates to add curb appeal. Stainless steel grates, for instance, work perfectly for aesthetics due to their bright and shiny appearance.
