Mild steel square tube box section is a quality strong metal product. 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 off rust then simply get this off 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 is 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.
We also carry a wide range of mild steel sheet metal, angle iron and flat bar.
Speciality Metals is known to be the United Kingdom’s best up-and-coming small-quantity metal company.
Furthermore we stock a vast range of round tube options that compliment our mesh range perfectly.
Over 50,000 customers of Specialty Metals are provided with fast, friendly customer service every year. We’re the place to try when you need metal of any shape and size. We’re based in Warrington, UK. We pride ourselves on our rapid turnaround and a large range of options.
Using stainless steel fittings with mild steel tube square pipes is technically feasible, but it’s essential to understand the potential complications. When two different metals, such as stainless steel and mild steel, come into contact in the presence of an electrolyte (like water), galvanic corrosion can occur. This is because these metals have different electrode potentials, and the less noble metal, in this case, the mild steel, will corrode faster than it would on its own. To reduce the risk of galvanic corrosion, ensure that the contact area between the metals is dry or shielded from electrolytes. Using a non-conductive barrier, like a plastic or rubber gasket or washer, can also help minimise direct metal-to-metal contact. Additionally, periodic maintenance checks are crucial to ensure that the mild steel hasn’t accelerated corrosion near the contact points with the stainless steel fittings. By taking the appropriate precautions, one can successfully use stainless steel fittings with mild steel tube square pipes in various applications.
Selecting the right paint for mild steel tube square pipes is crucial to ensure longevity, aesthetic appeal, and protection from environmental factors. For mild steel, priming is paramount to prevent rusting. A zinc-rich primer is particularly effective as it offers sacrificial protection, preventing oxidation. Following priming, an epoxy-based paint can be applied. Epoxy paints form a hard, durable surface that adheres well to the steel, offering both protection and a smooth finish. For outdoor applications or areas with high humidity, a top coat of polyurethane paint can further enhance protection, providing a barrier against UV rays, moisture and other environmental stressors. Regardless of the chosen paint, thorough surface preparation, including cleaning and removing any existing rust or mill scale, is essential to ensure optimal paint adhesion and performance.
Proper Joint Preparation: Clean the surfaces to be welded thoroughly. Remove any rust, oil or contaminants to ensure a consistent and clean weld.
Tack Welding: Place small tack welds at regular intervals along the joint before executing the final weld. This ensures the pipes stay aligned and minimises movement during welding.
Balanced Welding: If possible, weld alternately on opposite sides of the square tube. This balanced welding technique offsets the heat and reduces the chances of distortion.
Use a Jig or Fixture: Holding the steel tubes securely in place using jigs or fixtures can help maintain alignment and resist the forces of distortion.
Control the Heat Input: Using the lowest possible heat setting that still provides adequate penetration is recommended. The lesser the heat input, the lower the amount of distortion.
Stitch Welding: Instead of continuous welding, consider using stitch welding. This method involves making a series of intermittent welds. It allows the material to cool between welds, reducing cumulative heat.
Backstep Welding: This is a technique where the general progression of welding might be left to right, but the actual welding is performed right to left. This helps in controlling distortion by spreading the heat more evenly.
Cooling Techniques: If appropriate, controlled cooling using wet rags or air blowers can help reduce distortion. However, rapid cooling can introduce other problems like increased brittleness, so it should be done with caution.
Interpass Temperature Control: If multiple passes are needed, ensure the previous pass is adequately cooled before starting the next. Maintaining a consistent interpass temperature can reduce distortion.
Use of Anti-distortion Compounds: These compounds absorb heat and can be applied to the backside of the weld joint. They help in minimising the heat affected zone, thereby reducing distortion.
Pre-stressing: This involves intentionally distorting the parts in the opposite direction so that during welding, they pull back into the desired shape.
Correct Welding Sequence: Follow a proper welding sequence to distribute heat evenly. For example, for a square pipe, you might start with one side, move to the opposite side, then weld the remaining sides.
