This is an article about choosing between aluminum profiles and steel. It mainly talks about which is cheaper, aluminum profiles or steel. It introduces the differences and advantages of the two from the perspectives of raw materials, processing, cost, maintenance, etc., so as to help you choose the material that meets your needs and expectations. I hope it can help those in need. Raw Materials The raw materials for aluminum profiles are more expensive than steel. The price of aluminum ingots (approximately 20,000 yuan/ton) is higher than that of ordinary steel (approximately 5,000 yuan/ton). However, the price of high-strength aluminum alloys (such as 7075) is close to that of specialty steel. Processing Costs Aluminum profiles are primarily extruded. Compared to steel rolling, the energy consumption is only one-third of that of steel, and the processing efficiency is much higher than that of steel. Therefore, aluminum profiles are more suitable for high-end customization needs. Overall cost is similar between the two. Transportation Costs Due to the low density of aluminum profiles, they are lighter. In terms of volume, steel is three...
