Civil Drainage Products


Innovative Drainage Products that Set The Benchmark

Instrumental in the design and establishment of galvanised steel drainage grates in
Australia over 40 years ago.

Today, Weldlok pioneers new and specialised designs for Australia’s growing needs.


Weldlok drainage grates comply with the following Australian Standards, unless stated otherwise:
• AS 3996:2019 Access covers and grates
• AS/NZS 4680:2006 Hot-dip galvanising
• ISO/IEC 17025:2017 Competence of testing and calibration laboratories


A range of Class B and Class D solid top ductile covers have been appraised by the Water Services Association of Australia (WSAA).


Weldlok Forgebar & Diamond grates are fully compliant with AS 3996:2019 and are suitable for both pedestrian and bicycle traffic environments.


Drainage grates are load class tested in our in‑house NATA‑accredited facility. Test reports are available on request, subject to conditions.

The National Association of Testing Authorities (NATA) is Australia’s Government-endorsed provider of accreditation for laboratories.
