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.
Mild steel box section, like other mild steel forms, is susceptible to chemical reactions when exposed to certain chemicals or solvents. Its composition mainly of iron, with a small percentage of carbon and other trace elements, defines its interaction with various substances.
Acids: Direct contact with acids, especially strong ones like hydrochloric or sulfuric acid, can lead to rapid corrosion and degradation of mild steel. Even weaker acids can cause corrosion over time if the steel is continuously exposed.
Bases: Mild steel also reacts with strong alkaline solutions, although generally at a slower rate than with acids. This can lead to surface changes and potential pitting over extended periods.
Water: Prolonged exposure to water, especially saltwater, can induce rusting due to the formation of iron oxide. This is a common issue with all forms of iron-based metals.
Organic Solvents: While many organic solvents, like acetone or toluene, won’t directly corrode mild steel, they can strip away protective coatings, leaving the steel vulnerable to other environmental factors.
Oxidizing Agents: Strong oxidising agents can promote the rusting process and degrade mild steel faster.
It’s essential to note that the rate and severity of these reactions can be influenced by factors like temperature, concentration of the chemical and the presence of other protective barriers on the steel. If a mild steel box section is to be used in environments with potential chemical exposure, it’s crucial to understand these interactions and take preventive measures. Applying protective coatings, paints or other treatments can often shield the steel from corrosive substances and prolong its lifespan.
The production of mild steel box sections commences with the selection of an appropriate steel slab, a foundational semi-finished product. Upon selection, the slab undergoes heating until it’s malleable and is then shaped into a long strip through a series of rollers in a rolling mill. This strip is subsequently cold-formed by a sequence of shaped rollers, giving it a rounded tube appearance. The edges of this tube then undergo electric resistance welding (ERW), where they’re fused together using heat generated from an electric current. This round tube isn’t the end product, however. It’s further reshaped into a square or rectangular section through dedicated forming processes, maintaining its precise shape by navigating through various sizing stations. After acquiring the desired shape, the lengthy tube is segmented into smaller sections, either by shearing or using a circular saw. Some sections might also be subjected to heat treatments like annealing to refine their grain structure and optimise mechanical properties. The final step often involves surface treatments—like galvanisation or painting—to bolster the section’s resistance to corrosion and enhance its visual appeal. Through these intricate processes, the mild steel box section is sculpted, offering a blend of strength and versatility apt for diverse applications.
Absolutely, the interior of a mild steel box section does require protection against corrosion, especially if it is exposed to moisture or corrosive environments. While the exterior of these sections is often the primary focus for protection due to direct exposure to environmental factors, the interior is equally susceptible to rust and degradation. Moisture can enter the interior through various means: from condensation, exposure to humid environments, or through direct contact with water in specific applications. Once inside, moisture can lead to the formation of rust, which can compromise the structural integrity of the section over time.
To combat this, several protective measures can be employed:
Galvanisation: By coating the steel with zinc, both the interior and exterior of the box section can be shielded from corrosion. Hot-dip galvanisation is especially effective as it ensures all surfaces, including the interior, are coated.
Internal Coatings: There are paints and coatings formulated specifically for steel that can be applied to the interior of the box section. These coatings form a protective barrier, preventing moisture and other corrosive agents from coming into direct contact with the steel.
Cathodic Protection: This technique uses a sacrificial anode to divert corrosive activity away from the steel, thus extending its lifespan.
Dehumidification: In environments where humidity can be controlled, maintaining low humidity levels can significantly reduce the risk of interior condensation and subsequent corrosion.
Design Considerations: Ensuring that the box section has adequate drainage or ventilation can also help minimise the accumulation of moisture inside.
