Rainwater and melting snow need somewhere to go, especially on busy sidewalks. Without proper drainage, water can collect around building entrances, public walkways and commercial properties, creating puddles and potentially icy conditions.
Sidewalk drainage grating helps water pass through a walking surface into a drainage system below. But choosing the right grating involves more than finding a panel that fits the opening. Here’s what matters when planning drainage for Ontario’s climate.
How Does Sidewalk Drainage Grating Work?
Metal bar grating uses a series of openings between its bars to let water pass through while providing a surface for pedestrians.
It’s commonly installed over drainage trenches, utility openings and areas where water needs to move below the walking surface.
The size and spacing of these openings matter. Larger openings may allow more water through, but pedestrian comfort and accessibility must also be considered.
Borden’s pressure locked sidewalk grating offers smaller, uniform openings designed to balance pedestrian use, drainage and structural strength.
Why Does the Drainage System Below Matter?
A sidewalk drainage grating can only work effectively if water has somewhere to go.
Water passing through the grating must drain away through the channel or collection system beneath it. Otherwise, it may collect below the surface and create problems during freezing temperatures.
Good drainage design should account for:
• Adequate water flow beneath the grating
• Properly sized drainage channels
• Access for cleaning and inspection
• Removal of leaves, sediment and other debris
Planning the entire system helps keep drainage functioning over time.
Can Sidewalk Grating Handle Ontario Winters?
Ontario’s freeze-thaw cycles create challenges for outdoor walking surfaces.
Open grating allows melting snow and rainwater to pass through, potentially reducing surface pooling. However, ice can still form, particularly when drainage openings become blocked.
Material selection matters too. Galvanized steel provides corrosion protection, while aluminum and stainless steel offer alternatives for environments exposed to moisture and de-icing materials.
What About Pedestrian Safety and Accessibility?
Drainage performance cannot come at the expense of pedestrian safety.
Opening size, slip resistance and transitions to surrounding pavement should all be considered. Municipal and accessibility requirements may also apply.
For areas exposed to wet conditions, Borden offers enhanced slip-resistant surfaces, including ALGRIP® and mechanically punched serrated finishes.
Choosing a Drainage Solution That Lasts
Effective sidewalk drainage grating combines water management, structural strength and pedestrian comfort. Considering the complete drainage system during design can help avoid maintenance problems later.

Quick FAQ
Does Sidewalk Grating Prevent Ice From Forming?
No. Sidewalk grating can help water drain away, but ice may still develop when water freezes on the surface or drainage openings become blocked. Regular winter maintenance remains important.
How Do You Keep Sidewalk Drainage Grating From Clogging?
Regularly remove leaves, litter, sediment and other debris from the grating and the drainage channel below. Inspection and cleaning frequency depend on the location and surrounding conditions.
Can Sidewalk Drainage Grating Support Maintenance Vehicles?
Certain configurations can accommodate occasional vehicle loads. Suitability depends on bearing-bar dimensions, panel span, support conditions and the expected loading. These requirements should be confirmed before installation.
