Stainless steel rectangular tube FAQ

MW METAL can offer a number of finishes such as mill finish, pickle finish, 600G polish, hairline finish by 180G, 240G, 320G, and 8k mirror.
The application's structural requirements, the environment (corrosive or not), and the intended load-bearing capacity dictate the necessary wall thickness.
Yes, these tubes can be bent or formed, but require careful handling to prevent deformation or cracking, especially with thinner walls and higher grade stainless steels.
Stainless steel rectangular tubes generally have a slightly higher initial cost compared to materials like carbon steel or aluminum, owing to their superior corrosion resistance, strength, and durability. However, the long-term value is enhanced by their extended service life and minimal maintenance requirements. Although market fluctuations can affect raw material prices, the recyclability and lifecycle cost efficiency of stainless steel often offset the upfront investment, making it a cost-effective solution for applications where performance and longevity are paramount.
Besides being highly recyclable, stainless steel's durability and corrosion resistance extend the lifespan of structures, reducing the need for frequent replacements and maintenance.
