35 x 2mm round mild steel tube 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 tube is made by welding a steel strip 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.
Steel tubes have long been a popular choice in construction and manufacturing industries, and the 35mm diameter x 2mm wall Mild Steel Round Tube by Speciality Metals is no exception.

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.
Joining or connecting mild steel round tubes can be achieved through various methods, depending on the application’s requirements and available equipment. Here are some common techniques:
Welding: This is the most robust method for joining mild steel tubes. TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding are commonly used, with the choice depending on the thickness of the tube and desired finish. Proper welding ensures a continuous metal connection, providing both strength and rigidity.
Bolting: In scenarios where welding might not be feasible or where a non-permanent joint is desired, bolted flange connections can be used. This involves attaching flanges to the tube ends and then bolting them together.
Tube Fittings: There are various proprietary tube fittings and connectors available in the market, designed specifically for quickly connecting tubes without welding. These may include push-fit connectors, clamp-on connectors and more.
Sleeve or Insert Joints: A smaller diameter tube or rod can be inserted into the ends of two tubes to join them, with the joint often secured using adhesive or additional fasteners.
Riveting: Rivets can be employed to connect tubes, especially in applications where a particular aesthetic or look is desired.
Brazing or Soldering: These methods involve melting a filler metal into the joint between the tubes. The filler metal has a lower melting point than the tubes themselves, allowing for a bond without melting the actual tube.
Adhesives: For certain applications, especially where the load-bearing requirement is minimal, strong industrial adhesives can be used to bond mild steel tubes.
When deciding on a method, it’s crucial to consider factors like the intended load on the joint, the environment in which it will be placed (for example, potential exposure to moisture which might affect some adhesives), and the tools and skills available. In many scenarios, especially in structural applications, welding remains the preferred method due to the strength and permanence it provides.
Yes, you can paint or coat mild steel round tubes. Doing so not only enhances their aesthetic appearance but also offers protection against corrosion and environmental factors. Here’s a brief guide on how to do it:
Surface Preparation: Before painting or coating, it’s crucial to prepare the surface. Start by cleaning the tubes thoroughly to remove any dirt, grease or oil. This can be done using a degreasing solution or a mild detergent.
Rust Removal: If the tubes have any rust, it must be removed to ensure a smooth and adherent paint finish. You can use sandpaper, a wire brush or a rust remover solution. For larger-scale applications or for a smoother finish, sandblasting might be employed.
Priming: Once the tube is clean and free of rust, apply a primer. Primers are essential as they provide better paint adhesion and increase the longevity of the paint job. For mild steel, a rust-inhibitive primer is often recommended.
Painting: After the primer has dried, you can paint the tube. You can use spray paint, brush or roller, depending on the size of the project and desired finish. It’s often best to apply multiple thin coats rather than a single thick one, allowing each coat to dry thoroughly before applying the next.
Coating: If you’re looking for added protection, especially against corrosion, you might consider additional coatings. Galvanising is a popular method where a thin layer of zinc is applied to the steel to protect it from rust. Another option is powder coating, which provides a durable and aesthetically pleasing finish. It involves applying a powdered paint material that’s then melted onto the surface using heat.
Maintenance: While paints and coatings enhance the durability and lifespan of mild steel tubes, periodic checks and touch-ups might be necessary, especially if the tubes are exposed to harsh environments.
Remember, the key to a successful paint or coating job lies in the preparation. Ensuring the tube’s surface is clean, smooth and primed will result in a longer-lasting and more attractive finish.
Mild steel tubes are valued for their balanced combination of strength and ductility, with tensile strengths typically ranging between 370-500 MPa and a yield strength around 250 MPa. Compared to stainless steel, which can have tensile strengths from 500-2000 MPa depending on the grade, mild steel might seem less formidable. However, mild steel’s ductility often surpasses that of many stainless steel grades. Aluminum tubes, on the other hand, are lighter and can have tensile strengths between 70-700 MPa based on the alloy, but they generally offer less strength than steel. Copper tubes, prized more for their conductivity than their strength, range in tensile strength from 210-420 MPa. Lastly, PVC tubes present a significant drop in strength, with tensile values around 40-80 MPa, but they’re chosen for applications mainly due to their lightweight and corrosion-resistant properties. In essence, while mild steel is outmatched in strength by certain grades of stainless steel or specific aluminum alloys, it remains a popular and cost-effective choice in many industries due to its blend of strength, workability and affordability.
