Mild square steel tubing is relatively easy to paint, but proper preparation is key to ensuring the paint adheres well and lasts a long time. The primary concern with painting mild steel is its susceptibility to rust and oxidation. Before painting, it’s essential to clean the surface thoroughly to remove any rust, dirt, grease or oil. Here are the steps to achieve the best results:
Cleaning: Start by cleaning the tubing using a degreasing agent or soapy water to remove any contaminants.
Rust Removal: If there’s any rust present, it should be removed using a wire brush, sandpaper or a rust removal solution.
Priming: Once the steel is clean and free of rust, a primer designed for metal surfaces should be applied. This step is crucial, as the primer provides a base for the paint to adhere to and offers an added layer of protection against corrosion.
Painting: After the primer has dried, you can apply the desired paint. It’s typically best to use paints formulated for metal surfaces, as they adhere better and offer enhanced protection. Multiple thin coats are better than one thick coat, ensuring each layer dries adequately before applying the next.
Sealing: While not always necessary, in particularly harsh environments, a clear sealant can be applied over the paint for extra protection.
By following these steps, mild square steel tubing can be effectively painted, offering not only an aesthetic upgrade but also an additional barrier against environmental elements.
Mild square steel tubing is not typically recommended for plumbing applications. The primary reason is its vulnerability to corrosion, especially when exposed to water for extended periods. Over time, the interior of the tubing can rust, which can contaminate the water and also compromise the integrity of the tubing, leading to potential leaks or failures.
Most plumbing systems require materials that can withstand prolonged contact with water without corroding. Historically, galvanised steel was used in plumbing, where the steel was coated with zinc to offer some protection against corrosion. However, over time, even galvanised pipes can corrode, leading to potential health concerns and system failures.
Modern plumbing typically utilizes materials such as copper, PEX (cross-linked polyethylene), PVC (polyvinyl chloride) or CPVC (chlorinated polyvinyl chloride) due to their resistance to corrosion, longevity and suitability for carrying potable water.
If you’re contemplating using mild square steel tubing in a setting where it will encounter water, like for decorative water features or certain outdoor applications, make sure to take protective measures, such as galvanising, painting, or sealing to delay corrosion. However, for traditional plumbing, especially for potable water, it’s advisable to use materials specifically designed for that purpose.
Temperature fluctuations bring about several changes to mild square steel tubing. As with most materials, steel expands with rising temperatures and contracts upon cooling. This natural thermal expansion and contraction can cause stresses, especially if the tubing is fixed in place. Moreover, while mild steel maintains its strength across moderate temperature variances, it can become brittle in extremely cold settings and softer under high heat. The speed of corrosion reactions can also be temperature-dependent, with warmer conditions generally accelerating corrosion, especially in the presence of moisture. Additionally, if the tubing undergoes repeated cycles of heating and cooling, this can lead to material fatigue, with micro-cracks potentially forming over time. Welded joints on the tubing deserve special attention, as their mechanical properties might differ from the rest of the tube, making them more sensitive to temperature changes. Lastly, in environments experiencing shifts from hot to cold, condensation can form on the tubing’s surface, presenting another potential avenue for corrosion. When using mild square steel tubing in varying temperatures, it’s imperative to factor in these potential effects and employ protective measures to ensure longevity.
