Why 42% of Stainless Steel Railings Corrode Prematurely
According to the 2023 Metal Construction Report[1], over 40% of stainless steel handrail failures stem from improper grade selection. Surprisingly, 316L stainless steel lasts 3x longer in coastal areas than 304 variants.
“In our 2025 beachfront project, we found pitting corrosion in 304 stainless steel railings after just 18 months,” recalls lead engineer Mark T. “Switching to 316L solved it completely.”
Stainless Steel vs Aluminum Railings: The 25-Year Test
| Stainless Steel Railings | Aluminum Railings | |
|---|---|---|
| Salt Resistance | 3,000+ hours[2] | 800 hours |
| Load Capacity | 500 lbs/ft | 300 lbs/ft |
For high-traffic areas, consider industrial-grade stainless steel handrail systems with…
