So whether you’re tackling a DIY project or a professional job, mild steel tubing from Speciality Metals has got you covered.
20 x 2mm mild steel tubing is used in many structural and engineering applications. The size refers to the outside diameter and then the thickness of the wall.
ERW means Electric Resistance Welded. ERW round tube is made when steel strip is welded to form a tube shape. The tube is continuously seam welded which means that there is a neat weld running along the inside of the tube.
Mild steel round tube is widely used in a variety of applications and also comes in both square and rectangular options.
Speciality Metals offers an excellent product in the form of their 20mm diameter x 2mm thick mild steel tubing. This type of tubing is available in various lengths and possesses a number of beneficial qualities. Its durability and versatility, for instance, make it an ideal choice for a wide range of applications. In addition to being cost-effective, it is also recyclable, making it an attractive option for those who are environmentally conscious. It also has excellent welding, forming, bending and machining abilities, making it a reliable choice for those who require precision work. Overall, this mild steel tubing is an excellent choice for those who want a sturdy, dependable material for their projects.
Speciality Metals is known to be the United Kingdom’s best up-and-coming small-quantity metal company.

Mild steel is a quality strong metal. However it is not rust proof and may do so over time. Please use galvanised or stainless steel if you need resistance to rust. If this metal tube does show signs of rust then simply remove this with WD40 or fine sanding.
The grade of plain steel that we have available has mechanical properties that provide excellent machinability, formability and weldability.
Mild steel can be welded and it’s also suitable for painting. Mild steel is a magnetic grade of metal. Magnets will stick to this sheet but it is not itself a magnet.
Yes, mild steel tubing can be drilled quite effectively. When working with mild steel, a softer metal compared to other steels, it’s crucial to utilize the appropriate tools. High-speed steel (HSS) drill bits are typically recommended for such tasks. As you drill, using a lubricant or cutting fluid is essential; it helps minimise the heat produced, ensuring a longer drill bit lifespan and a smoother drilling experience. To guarantee precision and safety, always clamp or securely position the tubing before drilling. For larger holes, beginning with a smaller pilot hole can streamline the process. It’s also wise to drill at a moderate, consistent speed, refraining from exerting excessive pressure which could dull or break the bit. As always, safety comes first; wearing safety glasses to shield against metal fragments is a must. Upon completion, it’s beneficial to deburr the drilled hole to eliminate any potentially hazardous sharp remnants.
Yes, mild steel tubing can be heat-treated, but its response to heat treatment will be different from that of high-carbon or alloy steels. The primary purpose of heat treating mild steel tubing would be to alter its mechanical properties, such as increasing its hardness or strength. Here’s a brief overview:
Annealing: This is a process where the steel is heated to a specific temperature and then cooled slowly. Annealing is used to soften steel, improve its ductility and refine its grain structure. Mild steel can be fully annealed to make it softer and more workable.
Normalizing: Mild steel tubing is heated to a temperature slightly above its critical point and then allowed to cool in open air. This process refines the grain structure and improves the uniformity of its properties.
Quenching: This involves heating the steel to a certain temperature and then rapidly cooling it in water, oil or another cooling medium. Quenching can increase the hardness of mild steel, but it won’t be as effective as with high-carbon or alloy steels. Mild steel doesn’t have enough carbon content to form much martensite, which is responsible for the increased hardness in high-carbon steels.
Tempering: After quenching, steel is usually very hard but also brittle. Tempering involves reheating the quenched steel to a lower temperature and then allowing it to cool. This process reduces the brittleness imparted by quenching.
It’s worth noting that while mild steel can be heat-treated, the changes in its mechanical properties will be limited compared to those achievable with high-carbon or alloy steels. If specific mechanical properties are desired, it’s often more efficient to start with a steel type known for those characteristics.
Absolutely, mild steel tubing can be powder coated, and in fact, powder coating is a popular finishing method for it. Powder coating involves applying a dry, powdered paint material to the surface of the metal. The coated object is then heated, causing the powder to melt and form a protective layer on the surface. This method is favored for its ability to provide a durable, uniform and attractive finish. Before powder coating mild steel tubing, it’s essential to properly prepare the surface by cleaning it thoroughly and removing any rust, grease or other contaminants. Often, a process like sandblasting or chemical pretreatment is used to achieve an ideal surface for adhesion. Once prepared, an electrostatic gun is used to spray the powder onto the tubing, ensuring even coverage. The coated tubing is then placed in a curing oven, where the powder melts and fuses into a solid, smooth layer. This protective layer not only enhances the aesthetic appeal of the mild steel tubing but also offers resistance against corrosion, chipping and scratching.
