Civil drainage solutions to ensure compliance in WA, VIC, NSW, and QLD

Drainage Grates/Drainage Covers

When it comes to civil drainage solutions, there’s no one set style uniformly used across the whole country. Most states, including Queensland, New South Wales, Victoria and Western Australia all have their own set of regulations that means there are some key differences in product requirements.

At Weldlok, we provide a range of civil draining solutions designed to suit your state’s specifications. Our teams have worked with local authorities and our customers to develop approved solutions for each state  with many options let us take you through  what’s available and how they differ from state to state.


Civil drainage solutions for New South Wales and Victoria

Gully grates for NSW and VIC roads

Gully grates are the most commonly seen along the edges of roadways and typically need to stand up to a lot of different vehicle and pedestrian use. We manufacture gully grates for NSW and Victorian roads, which meet the standards for use in main roads and sub-divisions across both states.

Designed to support heavy vehicle traffic, our gully grates are manufactured using Forgebar® grating or its alternative diamond pattern grating where additional load-bearing capacity or vehicle movement needs to be accommodated.

Weldlok Gully Grates are designed to be long-lasting and robust, manufactured to meet the relevant AS 3996:2019 vehicle load class requirements. Our bicycle-safe design offers bolt-down security for added safety, and a hinged option provides for easier access and maintenance long term as covers can be easily replaced.
