We have supplied perforated metal stair risers for both industrial staircases and decorative architectural projects. The material choice depends on your environment. 304 stainless steel works for most indoor applications where moisture is not a major concern. For outdoor areas near the sea or in chemical plants, 316 stainless steel gives better salt spray resistance. The holes can be round, square, or slotted, and we adjust the hole size and pattern to meet your airflow or aesthetic requirements. Unlike solid risers, perforated ones reduce wind load on outdoor stairs and prevent dirt buildup. We also offer carbon steel with hot‑dip galvanizing as a lower‑cost option, though it does not match stainless steel's long‑term shine.

Advantages
The perforated metal stair risers let air pass through, which reduces pressure on outdoor stairs during high winds. They do not collect dust or debris like solid risers, so cleaning takes less time – important for food processing or pharmaceutical plants. The material meets ISO 9001 standards, and we can provide test reports for material grade. For your project bidding, we supply reference photos of previous installations, including a juice factory in Guangdong and a seaside observation deck in Hainan.
Customization
You can order as few as 100 pieces for the first batch. We help new customers with a discount. Drawings in CAD or 3D format are available for your design team. Our engineers typically respond with a solution within a few hours. Sample production takes about 7 days.
FAQ
Q1: Are these risers suitable for outdoor staircases near the ocean?
Yes. Use 316 stainless steel. We have installed them on a coastal platform in Hainan; after two years, no rust or pitting appeared.
Q2: Can you match the hole pattern to an existing staircase?
Yes. Send us a photo or drawing. We can replicate round, square, or custom slots.
Q3: What is the lead time for a custom order?
Sample: 7 days. Mass production: 15–25 days after sample approval. We ship by sea or air.
