If you've ever specified drainage for a commercial or public space, you've probably come across the term heel guard grate. But what exactly makes a grate a "heel guard", and how do you know when you need one?
Here's a straightforward answer.
The Short Version
A heel guard grate is a drain grate with a tight, close-set aperture pattern -- the gaps between the bars are small enough that a narrow heel can't pass through.
Standard slot drains have wider gaps that prioritise drainage flow. That's fine for most applications. But in spaces where people walk in heeled footwear, those gaps become a safety hazard. A heel can catch, twist, or cause a fall. A heel guard grate solves the problem without sacrificing drainage performance.
Where Are Heel Guard Grates Used?
Heel guard strip drains are specified wherever foot safety and drainage need to work together. Common applications include:
- Public walkways and urban pavements
- Government facilities and council infrastructure
- Commercial bathrooms, change rooms, and amenities blocks
- Hotel lobbies, pool decks, and spa facilities
- Shopping centres and retail precincts
- Restaurant, kitchen and hospitality venues
- Residential pool surrounds and outdoor entertaining areas
Any space that sees a mix of footwear, or where WHS (Work Health and Safety) compliance is required, is a candidate for a heel guard strip drain.
What Are the Key Features of a Heel Guard Grate?
A well-made heel guard grate needs to do more than just cover a drain. It needs to be:
- Anti-slip: The surface finish should meet slip resistance requirements, particularly in wet conditions.
- Load-rated: Depending on the application, heel guard grates may need to handle pedestrian, wheelchair, or even vehicle traffic. Load ratings are specified to suit.
- Durable: In outdoor and commercial settings, material quality matters. Stainless steel is the standard choice because it handles moisture, chemicals, and heavy use without deteriorating.
- Low profile: The grate should sit flush with the surrounding surface. A raised edge creates its own trip hazard.
- Minimal in appearance: In architectural and commercial settings, the grate should complement the surrounding environment rather than stand out from it.
Why Stainless Steel?
Most heel guard grates for commercial and government applications are manufactured from 316L grade stainless steel. This is marine-grade steel, which means it resists corrosion even in wet, high-traffic environments.
316L is also preferred for its welding properties, which matters in a precision-manufactured product like a heel guard grate where tight tolerances are critical.
Heel Guard Grates vs Standard Drain Grates
The main difference is aperture size. Standard strip drain grates typically have wider slots that allow higher drainage volume. Heel guard grates have a finer, tighter pattern that reduces the gap to a size that won't trap a narrow heel.
The trade-off is minimal. Modern heel guard strip drains are designed to maintain adequate drainage even with a tighter aperture. For most pedestrian applications, drainage performance is not compromised.
If you're unsure whether your project needs a heel guard grate or a standard grate, the question to ask is: who's walking on it, and in what footwear? If the answer includes heels, or if you're not certain, the heel guard is the safer specification.
Are Heel Guard Grates Made to Custom Sizes?
In most cases, yes. Standard off-the-shelf heel guard grates are available in some applications, but for strip drain installations they're typically manufactured to fit the channel dimensions of the specific project.
At Strip Drains, all our stainless steel heel guard grates are custom made to order. We manufacture from our Sydney facility and ship Australia-wide.
