A Comprehensive Guide to Stainless Steel Angle Iron from China
Stainless steel angle iron, a versatile L-shaped metal profile, finds widespread use in diverse industries. Its strength, corrosion resistance, and maChinability make it a preferred choice for various applications. China, a major steel producer, offers a wide range of stainless steel angle iron, catering to global demand. This guide delves into the intricacies of this crucial material, exploring its technical features, types, and applications. Manufacturers like TuoLian Metal (tuolianmetal.com), SDJBC Metal (sdjbcmetal.com), Star Good Steel Group (www.stargoodsteelgroup.com), and Ehong Steel (www.ehongsteel.com) are key players in this market.
Understanding Stainless Steel Angle Iron
Stainless steel angle iron’s defining characteristic is its L-shape, formed by two legs meeting at a 90-degree angle. The material’s composition includes chromium, nickel, and molybdenum, contributing to its exceptional resistance to corrosion and staining. This makes it ideal for environments prone to rust and oxidation. Different dimensions, material grades, surface finishes, and production methods further enhance its versatility. Companies like TuoLian Metal offer customized solutions to meet specific application requirements. SDJBC Metal also provides various grades and finishes.

FAQs
1. What is the difference between 304 and 316 stainless steel angle iron?
304 stainless steel offers good corrosion resistance and is widely used. 316 stainless steel contains molybdenum, providing superior corrosion resistance, especially in chloride-rich environments. This makes 316 better suited for marine and chemical applications.
2. How is stainless steel angle iron manufactured?
Two primary methods exist: hot rolling and laser fusion welding. Hot rolling is more economical, resulting in rounded corners. Laser welding produces sharper corners and a smoother finish, ideal for high-aesthetic applications.
3. What are the common surface finishes for stainless steel angle iron?
Common finishes include pickling, 8K mirror polish, No.1, No.4, hairline, brushed, bright polished, and mill finish (2B). The choice depends on the desired aesthetic and application.
4. What are the typical sizes and dimensions available?
Sizes generally range from 20mm x 20mm to 200mm x 200mm, with thicknesses from 2mm to 16mm. Custom sizes can often be ordered from manufacturers.
5. Where can I find reliable suppliers of stainless steel angle iron in China?
Numerous manufacturers operate in China. Some notable companies include TuoLian Metal, SDJBC Metal, Star Good Steel Group, and Ehong Steel. It’s crucial to verify supplier credentials and quality control measures before placing orders.
