Nowadays, cold-rolled steel has become one of the most important materials, widely chosen by contractors for construction projects. So, what exactly is cold-rolled steel, and what are its outstanding features? How much does it cost on the market? For a more detailed look, let’s explore this topic with Stavian Industrial Metal through the article below!
Cold-Rolled Steel – A Material Preferred by Many Contractors
Cold-rolled steel is a type of steel that undergoes a zinc-aluminum coating process, followed by rolling and covering with an aluminum alloy layer. This alloy layer mainly consists of 55% aluminum, 43.5% zinc, and 1.5% silicon. Thanks to the zinc coating, cold-rolled steel has excellent corrosion resistance and other outstanding advantages, making it four times more durable than conventional steel. Additionally, this product can withstand solar radiation, making it an ideal choice for roofing applications in homes, villas, warehouses, industrial zones, and other civil projects.
Cold-rolled steel has excellent corrosion resistance and many outstanding advantages
Cold-rolled steel is produced from steel coils through a cold rolling process after being descaled and oiled. First, the steel coils are sent into a cold-coating line, where the surface is cleaned once again before being placed into a NOF annealing furnace to improve the physical and mechanical properties of the steel sheet.
Next, the steel is coated with a zinc-aluminum layer using a hot-dip process with air-knife technology. Finally, the surface is covered with an anti-fingerprint layer, oil, or chromium to protect and prevent oxidation effectively.
Currently, cold-rolled steel is manufactured using modern NOF technology, which is environmentally friendly. This ensures superior corrosion resistance, oxidation resistance, and a smooth, shiny surface, enhancing the aesthetic appeal of any construction project.
Additionally, cold-rolled steel products comply with various international standards, including:
