FLAT stormwater GRATES

Flat grates by SVC Civil are a high-value, low-cost solution for off-road and behind-kerb stormwater drainage applications.

Available in various sizes with a bike-safe forgebar design, flat grates are compliant with load classes A, B, C and D as per AS3996:2019 – Access covers and grates. They are designed with a bolt-down feature preventing unauthorised access.


Standard flat stormwater grates in load classes B and D are available to order pre-encased in concrete. This provides significant time savings during installation, as no building of formwork or pouring concrete is required.

Produced in a controlled factory environment, concrete-encased flat grates are consistent in performance and appearance compared to concrete surrounds that are poured in-situ.


Pedestrian access (also known as Heelguard or Heelsafe) grates are slip-resistant and comply with AS3996:2019 in load classes A, B, C and D.

They are available to suit standard pit sizes of 450 x 450, 600 x 600, 900 x 600 and 900 x 900.


Flat or V-shaped grates are available in either a forgebar or weaved grating pattern, suitable for installation in roadside applications within the kerb and channel. 

All kerb, gully and V-grates are compliant with AS3996:2019 design requirements in Load Class D, and are suited to EDCM and council grate specifications. EDCM grates for the B2, SM2 and SM2 modified kerb profiles are available to purchase pre-encased in concrete.


Converted side entry grates (also known as crossover grates) are used to convert side entry pits into junction pits, while still allowing water to be channeled into the pit. 

This is often required when new driveways are built, or existing driveways extended. SVC stocks converted side entry grates in bullnose and rollover profiles.


The innovative tiered grate system from SVC Civil is a unique engineering solution designed for areas prone to kerb overflow and flooding.

Tiered flood grates capture higher volumes of stormwater than standard grate systems and are optimised for installation in low points. They are available in both barrier and semi-mountable kerb profiles.


SVC trench grates are available in Classes B, C & D, suiting clear opening widths of 150, 240 and 300mm. They are manufactured with bolts and clips for easy lockdown. 

Trench grate inserts are available in 1m modules and can be removed from the frames for extra convenience during installation.


Available in 100mm, 150mm and 200mm widths, our Trench Channel Sets are composed of a steel grate and formed channel that allows an easy drop-in solution for linear drainage applications. 

Trench Channel sets are compliant with Load Class B as per the AS 3996:2019 requirements.


SVC manufactures galvanised steel pipe grilles to suit specifications by Melbourne Water. 

Standard type 1 and type 2 sizes are available in stock, and type 3 custom size pipe grilles are manufactured to order.


Trash grates are available for debris and silt filtration and are commonly used in stormwater detention, retention and trade waste pits.

A selection of sizes and types are available for filtration of fine or medium particles.


Surcharge pit grates are installed above a pit and are used in circumstances where stormwater may be required to discharge from the top of the pit. They consist of a hinged grate and frame and standard bolt-down legs.


For special projects, SVC can supply bespoke stormwater grates to suit large format or special size requirements.

Please note that all custom-made grates will incur additional lead times.
