Mild steel rectangular tubing, also known as hollow sections (HSS) or box sections, are very popular in manufacturing, construction, engineering and fabrication. Our mild steel rectangular tube S235/S275 is a rectangular-shaped unalloyed low carbon mild steel grade tube.  These metal tubes provide high strength with minimal weight, which is ideal for many applications. Mild steel rectangular tubes from Buy Metal Online are available in a range of sizes at 1000mm lengths. We offer a free cutting service with every order.

Common uses of mild steel rectangular tube

Hot rolled steel means we can create box sections while maintaining core strength. While not suitable for heavy-duty use, mild steel rectangular hollow sections are used extensively throughout the country. You’ll find mild steel rectangular tube used extensively in:
  • Construction: Anywhere lightweight steel tubing is required where its modest strength is suitable. It is often used for internal structures, adding rigidity to forms and other uses.
  • Manufacturing: The box section is a robust shape offering higher strength than the thickness and weight would indicate, ideal for many applications.
  • General use: You can find mild steel rectangular tubes in caravans, trailers, air conditioning systems, homes, workshops, schools and anywhere a box section adds value.
A mild steel rectangular tube can be used anywhere, from bike racks to fencing, furniture to signage. There are so many possibilities!

Benefits of mild steel

The benefits of mild steel are many and varied. Perhaps that’s why it’s one of the most common man-made materials around! Key benefits of mild steel include:
  • Availability: Mild steel is plentiful in supply and easy to manufacture, meaning it can be made in high quantities.
  • Cost-effectiveness: The abundance of mild steel means that the material is relatively low-cost. The main cost in the manufacturing of mild steel is energy, and you’ll often find this is reflected in the lower purchase cost.
  • Flexibility: Mild steel can be shaped, rolled, cut, bent, welded, painted, treated and used in a variety of applications.
  • Strength: Mild steel offers decent strength for its weight, especially when in rectangular tube form.
Mild steel rectangular tubing uses standard steel sheets hot rolled into shape, retaining the strength and characteristics we need. As a low-carbon steel specification, mild steel rectangular tube S235/S275 provides low strength with good machinability and is suitable for welding. Use it anywhere you need a little rigidity without adding too much weight.

Bright Steel is steel which has been rolled at room temperature, below its recrystallization temperature. This increases its strength and hardness and decreases its ductility. In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product.   Other sizes are available upon request, please contact sales@buymetalonline.co.uk with your requirements

Hot-dip galvanising is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanised steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a “spangle”)

Stainless Steel Flat Bar 304/304L is a flat shaped 304/304L Stainless Steel Alloy bar. 304/304L Stainless Steel Alloy has excellent mechanical properties and is resistant to many corrosive agents. It is useful where sanitation and cleanliness are important. Non magnetic in the annealed condition. Hardness and tensile strength can be increased by cold working, but modified by lowered carbon content providing good resistance to corrosion in welded construction where subsequent heat treatment is not practical. Grade 304L (L= low carbon) is the same as the 304 except it has an extra-low-carbon analysis, the advantage of which is that it precludes any harmful precipitation in the 800º F to 1500º F range, such as might otherwise occur in welding heavier sections.

Stainless Steel Flat Bar 316/316L is a flat shaped 316/316L Stainless Steel Alloy bar. 316 Stainless Steel Alloy is a standard molybdenum-bearing grade, the second most commonly sought after grade next to grade 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance in chloride environments. Grade 316L (L= low carbon) ) is the same as 316 except it has an extra-low-carbon analysis, the advantage of which is that it precludes any harmful precipitation in the 800º F to 1500º F range that might result from welding heavier sections. Therefore 316L is extensively used in heavy gauge welded components. Typically there is no price difference between 316 and 316L stainless steel.
