Mild Steel

Here at Austen Knapman we stock a wide range of mild steel, all available cut to your size requirements. Simply input your measurements online and we'll provide an instant price, allowing you to buy only the materials you need. Whether it's a small DIY project or you have larger construction needs, our steel can be bought quickly and delivered to your chosen address.

As the most commonly available form of steel, mild steel is incredibly versatile, cost-effective and easily fabricated. It is often preferable to other forms of steel because it contains a relatively low amount of carbon, which maintains the strength but makes it more ductile and easy to work.

Suitable for use in the manufacturing and transporting of an infinite range of domestic and commercial products, mild steel has a reduced tensile strength when compared with high or ultra-high carbon steels but more than makes up for this in its cost-effectiveness and versatility. It is suitable for cutting, drilling and welding, making mild steel box section and round bar a popular choice of material in the construction of frames and semi-permanent structures.

We have a selection of products in stock from galvanised mild steel tube to flat bar and box section, all available cut to size to suit your project. Simply enter the dimensions you require into our free price calculator to receive a free on-screen quote for your order!
