When your project demands a flat, consistently sized metal blank and off-the-shelf stock just won't cut it, these mild steel round discs are the answer. Fabricators, welders, hobbyists, and workshop makers who need reliable circular blanks — without the time and waste of cutting their own — will find these discs ready to use straight from the pack.
Each disc is cut from mild steel (low-carbon steel, typically S235/A36 equivalent) and is available in diameters from 50 mm (approx. 2 in) up to 250 mm (approx. 9.8 in), with thickness options ranging from 0.6 mm (approx. 0.024 in) to 20 mm (approx. 0.79 in). Packs are offered in quantities of 1, 2, 4, or 8 pieces depending on the size selected, so you can order exactly what your job requires.
Typical applications include base plates and end caps for structural or decorative tube work, blanks for plasma or laser engraving, clock faces and decorative wall art, garden sculpture and outdoor metalwork, and flanges or backing plates in light engineering — making these mild steel circle blanks a versatile stock item for any metal workshop or DIY shed.

Select the diameter that matches the circular blank size your project requires — options run from 50 mm (approx. 2 in) to 250 mm (approx. 9.8 in). For thickness, thinner discs (0.6–2 mm) suit decorative, sheet-metal, or lightweight applications, while thicker discs (3–20 mm) are suited to structural, load-bearing, or heavy fabrication work. If in doubt, choose a thickness that matches the wall thickness of any tube or section you are welding the disc to.
Mild steel has a typical tensile strength of around 400–550 MPa, making it suitable for a wide range of structural and load-bearing applications at appropriate thicknesses. For critical structural applications, always consult a qualified engineer to confirm the correct specification for your load requirements.
Mild steel will oxidise (rust) if left unprotected in outdoor or humid environments. For outdoor use, apply a suitable metal primer followed by a topcoat paint, powder coat, or galvanising treatment before installation. Properly coated mild steel performs well in outdoor applications.
Yes. Mild steel is one of the most weldable metals available and is compatible with MIG, TIG, and stick (MMA) welding processes using standard mild steel filler wire or electrodes. No special pre-heating is required for most thicknesses in this range under normal ambient conditions.
Pack quantities vary by diameter and thickness combination — options include 1, 2, 4, or 8 pieces. Select the variant that matches your required quantity. If you need a larger quantity than listed, consider ordering multiple packs or contact us to discuss bulk options.
Yes. Mild steel machines readily with standard HSS or cobalt drill bits, angle grinders, and plasma cutters. Use appropriate cutting fluid when drilling thicker sections to extend tool life and achieve a cleaner finish. Always wear appropriate PPE when machining or cutting steel.
Surface finish and any protective coating vary by variant — please refer to the variant options or contact us to confirm. If the discs arrive with a light mill scale or protective oil film, clean the surface with a degreaser before painting or welding for best adhesion and weld quality.
