Innovative Drainage Products that Set The Benchmark

Weldlok was instrumental in the design and establishment of Galvanised Steel Drainage grates in Australia over 40 years ago and continues to pioneer new and specialised designs. Weldlok Drainage Grates are considered the industry benchmark amongst civil products. We are the only Australian manufacturer of drainage grates to offer a product which is load tested by our NATA accredited facility (12043) as well as complying to AS3996-2019.

Weldlok Drainage Grates are batch tested at our NATA accredited facility (12043) in compliance with Australian Standards.

Standards compliance – Weldlok Drainage Grates comply with the following Australian Standards, unless stated otherwise:

  • AS3996–2019 – Access covers and grates
  • AS/NZS4680:2006 – Hot-dip galvanising
  • ISO/IEC17025:2017 Competence of testing and calibration laboratories

Hydraulic performance – Weldlok Forgebar Grating provides superior hydraulic capacity over traditional cast iron grates.

Pedestrian/bicycle safe – Weldlok Forgebar & Diamond grates are fully compliant with AS3996 and are therefore suitable for both pedestrian and bicycle traffic environments.

Testing – Drainage grates are load class tested in our own NATA-accredited load test 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.
