When sourcing stadium stands, prioritize structural integrity and material durability. For outdoor use, ensure the steel structure is hot-dip galvanized to prevent corrosion, or use anodized aluminum alloy for lightweight, rust-proof performance. The seating should be made of High-Density Polyethylene (HDPE) with UV inhibitors to prevent fading and cracking under direct sunlight. Additionally, verify the load-bearing capacity, which should typically meet or exceed 5kN/m² for public assembly areas.
