High-quality rectangular steel pipes that are pickled, cold-rolled, annealed and air-dried for 24 hours. Widely used in various industries due to its reduced hardness and easy secondary processing.
Black annealed rectangular steel pipes are made by pickling strip steel and then cold-rolling it into strips of the required width. These strips are then annealed and air-dried for 24 hours before being rolled into shape. This process results in high-quality rectangular steel pipes that are widely used in furniture, fence, roofing, interior decoration, building curtain wall, and other industries.
The main advantage of black annealed rectangular steel pipes is that they have reduced hardness, making them less likely to break. This allows for easier secondary processing and deformation, which is essential in many industries.
These pipes are also highly durable, making them an ideal choice for outdoor use and areas with high humidity. They are resistant to rust and corrosion, making them suitable for use in harsh environments.
Overall, black annealed rectangular steel pipes are a versatile and reliable choice for any industry that requires high-quality piping. They offer exceptional durability and are easy to work with, making them a popular choice for many different applications.
