product Description
304L stainless steel beams (UNS S30403) have excellent welding performance and resistance to intergranular corrosion. They are suitable for indoor and outdoor structures of urban buildings, such as glass curtain wall frames of commercial complexes and exposed load-bearing beams in hotel lobbies. Their surfaces can be polished to present a mirror effect, and no additional anti-corrosion coating is required, reducing maintenance costs.
316L stainless steel beams (UNS S31603) add 2-3% molybdenum to form a stronger chloride ion corrosion barrier, which can resist long-term erosion by salt spray and industrial acids and alkalis, while meeting the needs of medical clean areas and food processing workshops for sanitary surfaces (easy to clean, no rust pollution).
It supports customization of complex sections such as H-type and I-type, and realizes arc and special-shaped structure design through laser cutting and bending processes. In addition, the 100% recyclable feature is in line with green building standards (such as LEED certification).
advantages
🔸 Are 304L/316L stainless steel beams magnetic?
No. These are austenitic grades, meaning they are non-magnetic in the annealed condition - ideal for design-sensitive spaces like airports or laboratories.
🔸 How long do stainless steel beams last in architecture?
When properly selected and installed, 304L/316L stainless steel beams can last over 50–100 years, especially in low-pollution or passivated environments.
