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
\n\n\n\nHow do I Maintain and Care for Mild Box Section Steel Tubes?<\/h2>\n
- \n
- \n
Regular Inspections<\/strong>: Periodically inspect the tubes for signs of rust, wear or physical damage. Early detection can prevent minor issues from becoming significant problems.<\/p>\n<\/li>\n
- \n
Clean Regularly<\/strong>: Dust, dirt and other contaminants can trap moisture, leading to rust. Use a mild detergent and water to clean the tubes. After washing, thoroughly dry the tubes to prevent water spots and potential rusting.<\/p>\n<\/li>\n
- \n
Protective Coatings<\/strong>:<\/p>\n
- \n
- Paint<\/strong>: Applying a fresh coat of paint not only enhances the appearance but also provides a protective barrier against rust. Before painting, ensure the surface is clean and free from rust.<\/li>\n
- Galvanisation<\/strong>: Galvanised mild steel has a protective zinc coating that offers substantial resistance to rusting. If the galvanisation wears off, consider re-galvanising or applying a zinc-rich primer.<\/li>\n
- Powder Coating<\/strong>: This is another protective and decorative finish that can be applied to the tubes. It provides a durable and rust-resistant surface.<\/li>\n<\/ul>\n<\/li>\n
- \n
Check Joints and Connections<\/strong>: If your tube structure is bolted together, periodically check to ensure all connections are tight. Loose connections can stress the tube, leading to deformation or failure.<\/p>\n<\/li>\n
- \n
Avoid Stagnant Water<\/strong>: If your tubes are placed outdoors, ensure they are positioned so that water does not collect and remain in or on them. Stagnant water accelerates rusting.<\/p>\n<\/li>\n
- \n
Treat Scratches and Dents Promptly<\/strong>: Scratches or dents can expose the raw steel beneath the protective coating, making it susceptible to rust. Clean the area and apply a primer followed by a touch-up paint to protect the exposed area.<\/p>\n<\/li>\n
- \n
Climate Considerations<\/strong>: If you live in a coastal or humid area, your steel tubes are more susceptible to rust due to the saline and moist environment. In such cases, more frequent inspections and maintenance might be required.<\/p>\n<\/li>\n
- \n
Limit Chemical Exposure<\/strong>: Avoid exposing the tubes to harsh chemicals, especially those that are acidic or corrosive. If they do come into contact, clean them immediately.<\/p>\n<\/li>\n
- \n
Storage<\/strong>: If the mild box section tubes are not in use, store them in a dry place, preferably indoors and off the ground. Stacking them with spacers in between can prevent moisture trapping.<\/p>\n<\/li>\n
- \n
Seek Professional Advice<\/strong>: If you’re unsure about the condition or how to care for your tubes, consult with a professional or the manufacturer. They can provide specific recommendations based on the steel grade and the environmental conditions of your area.<\/p>\n<\/li>\n<\/ol>\n
\nHow do I Connect or Join Mild Box Section Steel Tubes?<\/h2>\n
- \n
- \n
Welding<\/strong>:<\/p>\n
- \n
- MIG (Metal Inert Gas) Welding<\/strong>: Common for mild steel due to its efficiency and strength. It’s suitable for both thick and thin-walled tubes.<\/li>\n
- TIG (Tungsten Inert Gas) Welding<\/strong>: Used for precision joins, especially when a cleaner finish is desired.<\/li>\n
- Stick Welding<\/strong>: An older method but can be useful for thicker sections or in environments where equipment portability is essential.<\/li>\n<\/ul>\n
After welding, it’s vital to clean the weld area and apply a protective coating to prevent rusting.<\/p>\n<\/li>\n
- \n
Bolting<\/strong>:<\/p>\n
- \n
- Drill holes in the desired locations on the tubes.<\/li>\n
- Use appropriate bolts, nuts and washers to secure the sections together.<\/li>\n
- This method allows for disassembly in the future.<\/li>\n<\/ul>\n<\/li>\n
- \n
Specialised Connectors<\/strong>:<\/p>\n
- \n
- There are various commercial connectors available designed specifically for square tubes. These might include T-joints, corner connectors or cross connectors.<\/li>\n
- They provide strong connections without the need for welding and can be particularly useful for modular structures.<\/li>\n<\/ul>\n<\/li>\n
- \n
Sleeve Joints<\/strong>:<\/p>\n
- \n
- One tube is inserted into a slightly larger one, essentially “sleeving” it.<\/li>\n
- The joint can then be secured using bolts, pins or even welding.<\/li>\n<\/ul>\n<\/li>\n
- \n
Adhesive Bonding<\/strong>:<\/p>\n
- \n
- Industrial-grade adhesives can bond steel sections together.<\/li>\n
- While not as strong as welding, adhesive bonding can be useful for applications with lighter loads or where welding might affect the material’s aesthetics.<\/li>\n<\/ul>\n<\/li>\n
- \n
Riveting<\/strong>:<\/p>\n
- \n
- Similar to bolting, rivets provide a permanent joint between tube sections.<\/li>\n
- It’s less commonly used than bolting or welding but can offer a distinctive appearance.<\/li>\n<\/ul>\n<\/li>\n
- \n
Flanges<\/strong>:<\/p>\n
- \n
- Flanges can be welded to the ends of tubes, allowing them to be bolted together.<\/li>\n
- This method is useful for connections that might need to be disassembled and reassembled.<\/li>\n<\/ul>\n<\/li>\n
- \n
Tab and Slot<\/strong>:<\/p>\n
- \n
- Tabs are cut out on one tube, and slots are made on the other.<\/li>\n
- The tabs are inserted into the slots and then welded for a secure connection.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
How do I Cut Mild Box Section Steel Tubes?<\/h2>\n
- \n
- \n
Safety First<\/strong>:<\/p>\n
- \n
- Wear appropriate personal protective equipment (PPE) such as safety glasses, gloves and ear protection.<\/li>\n
- Ensure the work area is well-ventilated if cutting indoors, especially if you’re using power tools that generate fumes.<\/li>\n<\/ul>\n<\/li>\n
- \n
Marking the Cut<\/strong>:<\/p>\n
- \n
- Use a straight edge or ruler and a metal scribe or marker to mark the exact location of your cut. This ensures accuracy and reduces the chance of making mistakes.<\/li>\n<\/ul>\n<\/li>\n
- \n
Manual Cutting<\/strong>:<\/p>\n
- \n
- Hacksaw<\/strong>: Suitable for small projects or single cuts. Ensure you have a blade designed for cutting metal. When using a hacksaw, secure the tube with a vise or clamps and apply consistent pressure while sawing.<\/li>\n
- Cold Chisel and Hammer<\/strong>: Not the cleanest method, but it can be used in a pinch. Mark the cut line, place the chisel on the mark and strike with a hammer. This method is more labor-intensive and less precise.<\/li>\n<\/ul>\n<\/li>\n
- \n
Power Tools<\/strong>:<\/p>\n
- \n
- Angle Grinder<\/strong>: One of the most common tools for cutting steel tubes. Fit the grinder with a metal cutting wheel. After marking the cut, use the grinder to make a clean cut through the tube. Ensure you’re cutting in a well-ventilated area and away from any flammable materials.<\/li>\n
- Circular Saw<\/strong>: Equipped with a metal cutting blade, a circular saw can also be used. However, it can be bulkier and less maneuverable than an angle grinder.<\/li>\n
- Chop Saw<\/strong>: Ideal for multiple cuts or if you need very straight cuts. Always use a metal cutting blade.<\/li>\n<\/ul>\n<\/li>\n
- \n
Tubing Cutters<\/strong>: Specialised tube cutting tools, similar to pipe cutters, are available. These are typically hand tools that you rotate around the tube, gradually tightening to cut through the metal. They offer a cleaner, burr-free cut.<\/p>\n<\/li>\n
- \n
Band Saw<\/strong>: For more industrial applications or workshops, a band saw with a metal cutting blade can provide precise, repeatable cuts, especially for thicker-walled tubes.<\/p>\n<\/li>\n
- \n
Laser and Plasma Cutters<\/strong>: These are advanced, industrial-grade tools that offer high precision and clean cuts. They’re ideal for workshops or manufacturing setups that need to cut large quantities or require high precision.<\/p>\n<\/li>\n
- \n
Finishing the Cut<\/strong>:<\/p>\n
- \n
- After cutting, there might be sharp edges or burrs. Use a file or an angle grinder with a flap disc to smooth the edges and make them safe to handle.<\/li>\n
- If you’ve used an angle grinder or saw, you might see discoloration around the cut due to heat. If aesthetics are a concern, this can be cleaned with a wire brush or sandpaper.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
