Mild Steel<\/h2>\n
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.<\/p>\n
- \n
- Bending & Forming \u2013 Fair. You could only bend this tubing with bending tools but not by hand<\/strong><\/li>\n
- Corrosion Resistance \u2013 Poor. Mild steel is uncoated, so there is no additional protection against corrosion<\/strong><\/li>\n
- Machining & Grinding \u2013 Good. Mild steel is the metal choice for many forms of machining and grinding, but stainless steel can also offer good results<\/strong><\/li>\n
- Welding \u2013 Excellent. You could easily weld with this tubing to suit your requirements<\/strong><\/li>\n
- Painting \u2013 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<\/strong><\/li>\n
- Wear Resistance \u2013 Fair. As there is no protective layer, we suggest stainless steel or galvanised steel if you require a stronger wear resistance<\/strong><\/li>\n<\/ul>\n
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.<\/p>\n

\nFAQs About This Product<\/h4>\n
Can Mild Steel Box Section Square Tubes be Welded?<\/h2>\n
Yes, mild steel box section square tubes can be welded. Mild steel is one of the most weldable materials, making it a popular choice for various applications that require welding. Here’s a brief breakdown of welding these tubes:<\/p>\n
- \n
- \n
Preparation<\/strong>: Before welding, ensure the surfaces to be welded are clean and free from contaminants like paint, rust or dirt. This will ensure a stronger and cleaner weld.<\/p>\n<\/li>\n
- \n
Welding Techniques<\/strong>:<\/p>\n
- \n
- MIG (Metal Inert Gas) Welding<\/strong>: This is a common method for welding mild steel. It provides strong welds, is efficient and is suitable for both thick and thin-walled tubes.<\/li>\n
- TIG (Tungsten Inert Gas) Welding<\/strong>: TIG welding offers more precision and control than MIG, making it ideal for detailed or intricate welds.<\/li>\n
- Stick or Arc Welding<\/strong>: A more traditional method, suitable for various applications, including those with thicker sections.<\/li>\n<\/ul>\n<\/li>\n
- \n
Welding Position<\/strong>: Depending on the construction or fabrication requirement, welding can be done in different positions \u2013 flat, horizontal, vertical or overhead. Each position may require specific techniques or adjustments to the welding equipment.<\/p>\n<\/li>\n
- \n
Post-weld Treatment<\/strong>: After welding, it’s advisable to clean the weld area of any slag (for stick welding) or spatter. If the welded object is intended for outdoor use or a corrosive environment, consider applying a protective coating to the weld area to prevent rusting.<\/p>\n<\/li>\n
- \n
Safety<\/strong>: Always use appropriate safety equipment, including welding helmets, gloves and protective clothing. Ensure the work area is well-ventilated to prevent the inhalation of harmful fumes.<\/p>\n<\/li>\n
- \n
Strength Considerations<\/strong>: When properly done, a weld on a mild steel box section square tube can be as strong as the tube itself. However, the strength of the weld can depend on the welding method used, the quality of the weld and the skill of the welder.<\/p>\n<\/li>\n<\/ol>\n
\n\n\nHow can I Prevent Rust and Increase the Longevity of Mild Steel Box Section Tubes?<\/h2>\n
Preventing rust and prolonging the life of mild steel box section tubes involves a combination of protective measures and regular maintenance. Here are some steps and considerations to help ensure your steel tubes last longer:<\/p>\n
- \n
- \n
Coatings<\/strong>:<\/p>\n
- \n
- Paint<\/strong>: A good quality paint can act as a barrier against moisture. Before painting, make sure the surface is clean and primed. Use rust-inhibiting primers and paints for optimal protection.<\/li>\n
- Galvanisation<\/strong>: This process involves applying a protective zinc coating to the steel to prevent rusting. Hot-dip galvanization provides a thick, durable layer that can last for decades in many environments.<\/li>\n
- Powder Coating<\/strong>: This is a type of coating that’s applied as a free-flowing, dry powder. It’s typically used to create a hard finish that’s tougher than conventional paint.<\/li>\n<\/ul>\n<\/li>\n
- \n
Environment<\/strong>:<\/p>\n
- \n
- Location<\/strong>: If possible, avoid placing the tubes in consistently damp or wet locations.<\/li>\n
- Ventilation<\/strong>: Ensure that the environment where the tubes are placed has good airflow, which helps to keep surfaces dry.<\/li>\n
- Desiccants<\/strong>: For indoor storage, use desiccants to absorb excess moisture.<\/li>\n<\/ul>\n<\/li>\n
- \n
Regular Maintenance<\/strong>:<\/p>\n
- \n
- Inspection<\/strong>: Regularly inspect the tubes for any signs of rust or wear. Early detection can allow you to treat and prevent further corrosion.<\/li>\n
- Cleaning<\/strong>: Dirt and grime can trap moisture, leading to rust. Regularly clean the tubes using a mild detergent, followed by a thorough rinse and drying.<\/li>\n<\/ul>\n<\/li>\n
- \n
Protection Against Physical Damage<\/strong>:<\/p>\n
- \n
- Scratches, dents or any physical damage can expose the steel’s underlying surface, making it susceptible to rust. Ensure the tubes are protected from significant impacts or abrasive activities.<\/li>\n<\/ul>\n<\/li>\n
- \n
Use of Rust Inhibitors<\/strong>:<\/p>\n
- \n
- Rust inhibitors are chemicals that can be applied to the steel’s surface to slow down or prevent the oxidation process. They are especially useful in environments where the steel is exposed to corrosive substances.<\/li>\n<\/ul>\n<\/li>\n
- \n
Sealants<\/strong>:<\/p>\n
- \n
- Applying sealants can provide an additional barrier to moisture, especially at welded or jointed areas.<\/li>\n<\/ul>\n<\/li>\n
- \n
Cathodic Protection<\/strong>:<\/p>\n
- \n
- This is a technique used to prevent rust by making the steel tube act as a cathode of an electrochemical cell. It’s a method more commonly used for pipelines and large metal structures.<\/li>\n<\/ul>\n<\/li>\n
- \n
Regularly Replace Protective Coatings<\/strong>:<\/p>\n
- \n
- Over time, protective coatings can wear out or get damaged. Regularly inspect them and replace or reapply as necessary.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
Can They be Galvanised After Fabrication?<\/h2>\n
Galvanising is the process of applying a protective zinc coating to steel to prevent rusting. The most prevalent method for this is hot-dip galvanising, wherein the steel object is submerged in a bath of molten zinc. When the fabricated mild steel box section tube is immersed, the zinc forms a protective layer that’s metallurgically bonded to the steel, providing durable and robust protection against corrosion.<\/p>\n
There are several considerations when galvanising after fabrication:<\/p>\n
- \n
- \n
Preparation<\/strong>: For effective galvanisation, the steel’s surface must be thoroughly cleaned to remove any dirt, grease or scale. This is typically achieved through a series of treatments, including degreasing, pickling (acid cleaning) and fluxing.<\/p>\n<\/li>\n
- \n
Venting & Draining<\/strong>: When fabricating items meant for post-fabrication galvanising, it’s essential to ensure proper hole placements to allow gases to escape during the dipping process and for the molten zinc to drain. Otherwise, trapped air can lead to explosions or imperfect coating.<\/p>\n<\/li>\n
- \n
Size & Geometry<\/strong>: The size of the fabricated item should be compatible with the dimensions of the galvanising bath. Also, some intricate or closed designs may pose challenges in ensuring the zinc penetrates all areas or drains correctly.<\/p>\n<\/li>\n
- \n
Distortion<\/strong>: Due to the high temperatures involved in hot-dip galvanising, there’s potential for distortion, especially with thinner materials or complex structures. It’s crucial to be aware of this and take preventive measures during the fabrication stage.<\/p>\n<\/li>\n
- \n
Finish & Aesthetics<\/strong>: The finished appearance of hot-dip galvanised steel can vary based on the steel’s chemical composition, the cooling rate and other factors. If a consistent finish is vital, additional processes, such as sandblasting or painting over the galvanised layer, might be considered.<\/p>\n<\/li>\n
- \n
Longevity<\/strong>: Galvanising after fabrication significantly enhances the life expectancy of the mild steel box section tubes, especially in environments prone to corrosion.<\/p>\n<\/li>\n<\/ol>\n
