How to prevent steel structure building from rusting
To prevent steel structure building from rusting, you can follow some of these tips:
Get a galvanized steel building: Galvanizing is the process of applying zinc coating to a metal (popularly steel or iron) to prevent corrosion or rusting. Galvanized steel is more resistant to rust than plain steel and can last longer.
Make sure proper steel structure installation: Steel structure installation should ensure proper drainage, ventilation, and maintenance access. Good drainage will help keep rainwater away from the metal surfaces where it could cause corrosion over time. Ventilation will help reduce humidity and moisture inside the building. Maintenance access will allow for regular inspection and cleaning of the steel components.
Add a protective coating: Protective coatings are added to steel to prevent oxygen from reaching the iron in the steel. There are different types of coatings, such as paints, oils, waxes, powders, or electroplating, that can provide different levels of protection and appearance.
Avoid cracks or scratches: Cracks or scratches on the steel surface can expose the iron to oxygen and moisture, leading to rust formation. Avoiding mechanical damage and repairing any defects as soon as possible can help prevent rust from spreading.
Control the humidity: Humidity is one of the main factors that contribute to rusting. Controlling the humidity inside and outside the building can help prevent rust from forming. This can be done by using dehumidifiers, fans, heaters, or air conditioners.
Use corrosion-resistant alloy: Some alloys of steel are more corrosion-resistant than others. For example, stainless steel contains at least 18 percent chromium, which forms a protective layer of chromium oxide on the metal surface. This oxide layer resists corrosion while preventing oxygen from reaching the underlying steel.
