Key information:

• Shape – Round Tube
• Grade – EN10305E220
• Hot or Cold Rolled – Hot Rolled
• External Diameter – 50mm
• Wall Thickness – 1.5mm
• Internal Diameter – 47mm

We also carry a wide range of mild steel sheet metal, angle iron and flat bar.

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.

• Bending & Forming – Fair. You could only bend this tubing with bending tools but not by hand
• Corrosion Resistance – Poor. Mild steel is uncoated, so there is no additional protection against corrosion
• Machining & Grinding – Good. Mild steel is the metal choice for many forms of machining and grinding, but stainless steel can also offer good results
• Welding – Excellent. You could easily weld with this tubing to suit your requirements
• Painting – Good. We suggest that a mild steel product is always used when a layer of paint needs to be applied. Galvanised and stainless steel will not take paint
• Wear Resistance – Fair. As there is no protective layer, we suggest stainless steel or galvanised steel if you require a stronger wear resistance

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.

FAQs About This Product

Does the Length of Mild Steel Round Tubing Affect its Structural Integrity?

The length of mild steel round tubing can influence its structural behavior, especially in terms of its ability to bear loads and resist bending or buckling. In structural engineering, the length-to-diameter ratio of a column or tube plays a crucial role in determining its buckling behavior.

As the length of the mild steel round tubing increases, its susceptibility to buckling under axial loads also rises. This is particularly true for slender columns or tubes, where the length significantly exceeds the diameter. When a long tube is subjected to compressive forces, it may buckle or bend outwards, even if the material itself remains intact. This phenomenon is due to the tube’s inability to handle the compressive loads over its extended length.

On the other hand, shorter lengths of tubing, with a more favorable length-to-diameter ratio, tend to be more stable and less prone to buckling under similar loads.

To ensure the structural integrity of mild steel round tubing in various applications, engineers often refer to the Euler’s buckling formula and other related design principles. These principles help determine the critical length and loads under which a given tube can operate safely without risk of buckling.

Can I use Mild Steel Round Tubing for Outdoor Furniture?

Mild steel round tubing is a popular choice for outdoor furniture due to its versatility, durability and ease of fabrication. When considering it for such applications, it’s essential to keep in mind a few things:

Durability: Mild steel, in its untreated state, is susceptible to corrosion, especially when exposed to outdoor elements like rain and humidity. To prevent rusting and enhance its lifespan, the mild steel tubing should be galvanised, powder-coated or painted. These coatings act as barriers against moisture and other corrosive agents, ensuring that the furniture remains robust and aesthetically pleasing for a more extended period.

Design and Fabrication: The flexibility of mild steel round tubing allows designers and fabricators to craft a wide variety of furniture designs, from simple benches to intricate table bases and chair frames. Its malleability enables bending and shaping without compromising structural integrity.

Maintenance: While coatings can significantly improve the longevity of mild steel outdoor furniture, periodic maintenance, like checking for scratches or wear in the protective layer, can help identify areas that may need touch-ups. This proactive approach ensures that the furniture remains protected against the elements.

Environmental Factors: If the furniture is to be placed in coastal areas or regions with high humidity, it’s particularly crucial to ensure that the protective coatings are of high quality and are maintained regularly.

How does Mild Steel Round Tubing Handle Vibrations?

Mild steel round tubing is widely utilized in various engineering and construction applications, in part due to its resilience and strength. When it comes to handling vibrations, several factors determine its performance:

Damping Capacity: Mild steel has a moderate natural damping capacity, meaning it can absorb and dissipate vibrational energy to some extent. Damping reduces the amplitude of vibrations, thus decreasing the potential for vibrational damage or noise. However, mild steel’s damping capacity isn’t as high as some other materials like cast iron.

Geometry and Wall Thickness: The way a mild steel round tube handles vibrations is also influenced by its geometry. A tube with a thicker wall will generally have more resistance to vibrations than a thinner one. The round shape of the tubing itself also provides uniform strength in all directions, contributing to its ability to resist bending or buckling under vibrational stresses.

Support and Boundary Conditions: How the tubing is supported or attached to other structures plays a crucial role in its vibrational characteristics. Properly supported and anchored tubing can minimize the transmission and amplification of vibrations.

Elasticity and Resilience: Mild steel possesses good elasticity, meaning it can return to its original shape after being deformed by vibrational forces. This property makes it less susceptible to fatigue, a form of failure caused by repeated stress cycles, such as vibrations.

Harmonic Resonance: Like all materials, mild steel tubing has natural frequencies at which it resonates. If an external force, like a motor or external vibration, matches this frequency, the tubing can experience amplified vibrations, which could lead to failure. It’s essential to consider potential resonance when designing systems or structures involving mild steel tubing.
