Work Smarter with Edcon Steel
Check Your Measurements: Always double-check the diameter you need for your steel disc to ensure a perfect fit. Planning the exact size (and any holes or cut-outs) upfront will save you time and rework.
Choose the Right Thickness: Select a disc thickness suited to your project. Thicker steel discs (e.g., 5 mm and above) provide extra strength for structural or load-bearing uses, while thinner discs (3 mm or less) are ideal for light-duty, decorative, or non-structural applications.
Protect Against Rust: If your steel disc will be used outdoors or in a high-moisture environment, consider painting it with a quality metal primer and topcoat or having it galvanised. This ensures long-term corrosion resistance, which is essential for marine, farming, or exterior construction uses.
Cut & Handle Safely: Always wear PPE and de-burr sharp edges after cutting. Don’t have the right tools? We’ll cut it for you with clean, accurate finishes, either while you wait in-store or with your online order.
Check with a Professional: All information here is general. Always confirm your steel sizes and load requirements with a qualified engineer or builder before installation to ensure compliance and safety.
Common Uses and Sectors: Steel Discs (Blank)
Steel discs (also known as blanks) are used across various industries, from heavy commercial fabrication to creative home projects. In construction and engineering, steel discs often serve as gussets, end-plates or caps, and load-bearing base plates. Their round shape distributes weight evenly without protruding corners, which is perfect for capping circular hollow sections or topping off steel pipe ends (for example, finishing fence posts or structural columns neatly). Builders value these discs for tasks like covering openings, creating custom washers or brackets, and reinforcing structures where a circular shape is beneficial.
In the manufacturing and automotive sectors, steel discs can be customised into flanges, gears, or mounting plates. They’re also popular in signage and metal art (a laser-cut steel disc makes a great blank canvas for signs, plaques, or public art installations).
DIY enthusiasts use steel blanks for a wide range of applications, from fire pit bases and stool tops to repair patches and unique garden features. Even in farming and fencing, steel discs come in handy for equipment repairs or as robust end-caps on posts and pipes to keep out moisture and pests. From marine projects (with appropriate corrosion protection) to general metalwork, these versatile round plates provide strength and stability wherever a durable circular steel component is required.

Do the Orange and Bathurst stores stock steel discs?
Yes. Our Orange and Bathurst stores carry a range of steel discs (blanks) in popular sizes and thicknesses. If the specific disc size or thickness you need isn’t on the shelf at those branches, we can cut it to order on-site or quickly transfer stock from another Edcon location. We make sure regional customers have full access to our steel range – with the convenience of local pickup or delivery as needed.
How much do steel discs cost?
The cost of steel discs depends on the diameter, thickness, and material of the disc. Generally, larger or thicker discs will cost more than smaller, thinner ones due to the extra steel and cutting time required. You can view live pricing on our website by selecting the size and thickness you need, or contact us for a quote on custom dimensions. Edcon Steel’s pricing is transparent – you only pay for the material and cutting you actually need, which is great for budget-conscious DIYers and bulk buyers alike.
What sizes of steel discs can I buy from Edcon?
We can supply steel discs in almost any size you require. Edcon stocks common standard discs (for example, rounds that match standard pipe diameters like 80NB, usually in 3 mm or 5 mm thick mild steel) for quick purchase. Beyond the stock range, our precision cutting machines can produce custom discs from just a few centimetres wide up to large-diameter plates. In practice, this means whether you need a tiny washer-like disc or a big circular plate (even over a meter across), we have the capability to cut it. Just let us know your required diameter and thickness, and we’ll make it happen to exact specs.
Any tips for using and maintaining steel discs?
Certainly. For best results, plan your project around standard disc sizes or thicknesses if possible – this can reduce waste and cost. Always de-burr the edges of a steel disc after cutting or drilling to remove any sharp edges (Edcon can do this for you when we cut your disc). If you’re welding a disc onto something, ensure the contact surfaces are clean and free of rust or paint for a strong weld. For outdoor use, apply a protective coating or choose galvanised/stainless options to prevent rust over time. And as always, when working with steel, use proper safety gear and handle the discs with care (they can be heavy and have sharp edges until finished). By following these tips, you’ll get maximum performance and longevity from your steel discs in any application.
