Ductile Iron covers and grates from Weldlok are made from exceptionally durable materials that provide efficient and safe pit and drain cover solutions for stormwater, sewer and pits on roads, footpaths, and commercial or heavy-duty industrial applications.

Manufactured from heavy-duty ductile iron, the Weldlok range of Ductile Iron access covers and grates are designed for numerous usages and loadings under strict design criterion utilising the Australian Standards as a guideline.

Advantages of Ductile Iron

Ductile Iron, also known as SG Iron, is a graphite-rich cast iron that is known for its mechanical properties such as high ductility, tensile strength, impact resistance, and corrosion resistance.

Ductile Iron consists of nodular graphite which gives it flexibility and due to this property, it very rarely completely destructs even under immense loadings but rather flexes and returns to a semi-original base whereas Grey Iron will shatter under loading with little or no warning. Obviously, when designing access covers one must keep in mind what a catastrophic failure would result in as usually the first thing to mind is human harm.

In comparison to Grey Iron, Ductile Irons have a high strength-to-weight ratio, which offers considerable weight savings over Grey Iron castings.

Superior Ductile Iron Covers & Drain Grate Solutions

At Weldlok, we design and manufacture various ductile iron solutions, such as concrete infill ductile square or rectangular, solid top ductile circular, and rectangular. 

Weldlok has a rigorous testing procedure in a NATA-certified facility that ensures any existing and or newly designed covers and grates are up to the designed task. The Weldlok team are experts in their field.

Our hybrid supply chain provides Weldlok with global reach to cutting-edge technology that can be adapted to Australian requirements. Our world-class production facilities are focused on Quality, Design, Community, Environmental & Health and Safety, supported by a dedicated team of professionals with vast experience in making our customers successful.
