Guide to Selecting The Right Drainage Grate

Drainage grates and drain covers come in various sizes and designs, from single panels to heel guard or diamond options, each are design to suit different applications. Choosing the right drainage grate for a project based on its unique needs impacts the effectiveness and functionality of drain grates.

Here are some things that to consider when selecting and specifying the correct drainage grate for your application.

1. Purpose

Drainage grates and covers have broad and varying uses. The first thing to check is where the drain will be installed and what sort of runoff it will support such as rainwater. When considering the location, it’s important to take into account the acidity levels of water where the drainage grates will be used.

In addition to where and what the grate will be draining you must consider the volume and frequency of water it has to deal with. This helps to determine the grate size and opening size. For instance, if you are using drain grates in city streets accessible by pedestrians or entertainment zones, you need to consider grates that not only collect water effortlessly but are corrosion resistant, safe for walking on, and can withstand maximum pedestrian traffic.

2. Traffic

Next is the type and volume of traffic. Drainage grates are designed with specific class loading and properties for different applications such as roads, pathways – even airports! Products are designed and engineered taking into account the amount of traffic it would receive. If your floor grating is set to experience a large amount of traffic, then you want to ensure3the grates you select match the load class required to provide lasting durability.

Most importantly, they stay in position with the moving vehicles and pedestrians. Galvanised drainage grates are available in different load bar sizes or diamond shaped patterns that are tested to withstand a higher load class and traffic movement, providing a durable and reliable water collection.

3. Weight Capabilities

Much like considering the traffic above, when choosing drain grates for applications like roads, pathways and driveways, such gratings must meet the necessary load-bearing capabilities to ensure safety. Start by checking with the load-bearing classes  and capabilities provided by the manufacturer to ensure that the drain grates you choose have the specific load capacity needed for your application.

4. Size Compatibility

Drainage gratings and covers come in numerous sizes that suit many applications including the most commonly used in Australia, and specific state-based sizes. Some applications, especially when retrofitting or replacing in older applications, may need different sizes than what is available as standard. At Weldlok, drain grates and covers are stocked in various standard sizes, ready for easy order, transport and installation through our national distribution centres. We also customise drain grates in sizes that fit drain widths and frames of any size with solutions that can be made in Australia.
