Custom-cut to Order Delivery or Click & Collect
At Edcon Steel, our Cast Iron 3D Grade products are available in a range of sizes and can be cut to your exact length.
Cast Iron 3D Grade is a high-quality engineering material known for its excellent machinability, vibration damping, and consistent structural performance. Commonly supplied in solid bar form with round, square, or rectangular profiles, it is designed for precision applications where stability and wear resistance matter.
This grade of cast iron is widely used across machining and fabrication because it delivers a fine, uniform grain structure that allows for clean cutting, drilling, and turning. It also offers good compressive strength and natural lubrication properties, making it ideal for components that experience friction or repetitive movement.
With five convenient NSW locations in Brookvale, Revesby, Blacktown, Bathurst, and Orange, and Australia-wide delivery, Edcon Steel makes it easy for builders, tradies and DIY customers to get quality cast iron for any job.

Work Smarter with Edcon Steel
Cutting & Machining: Use sharp carbide tooling and moderate speeds for best results. Cast iron machines cleanly but produces fine dust, so extraction is recommended.
Corrosion Protection: Cast iron can oxidise over time. Apply oil, paint, or a protective coating if used in exposed environments.
Handling & Storage: Store in a dry area and keep off the ground to prevent moisture exposure and surface rust.
Ordering Tips: Order cut-to-size lengths to reduce machining time and material waste, especially for repeat parts or production runs.
Check with a Professional: Our advice is general in nature. Always confirm your specific steel sizes, load-bearing requirements and compliance needs with a qualified engineer or builder, especially for structural applications. This ensures your project is safe and meets all regulations before you build.
Common Uses and Sectors: Cast Iron 3D Grade
Cast Iron 3D Grade is widely used across machining, construction, and engineering industries due to its reliable performance and ease of fabrication. In building and construction, it is often used for base plates, machine mounts, and structural components that require rigidity and vibration control. Its stability makes it a preferred choice for workshop tooling, jigs, and fixtures.
In civil works and infrastructure, cast iron components are used in support systems, mechanical assemblies, and heavy-duty applications where compressive strength is essential. For residential and DIY projects, Cast Iron 3D Grade is suitable for custom brackets, decorative elements, and workshop builds where durability matters.
