Surface treatment standard
The thickness of hot dip galvanized layer is ≥60μm, and the spray thickness is recommended to be 80-120μm to ensure outdoor weather resistance.
View test reports (e.g. salt spray test results).

Step non-slip design
Tread to make non-slip lines (such as serrations, grooves), or lay anti-slip pads, rubber strips.

Structural safety
The distance between the vertical rods is no more than 15cm, the step height is 15-18cm (ergonomic), and the welding points need to be reinforced to prevent rust.

Part quality
Handrails and connectors use 304 stainless steel or galvanized steel to avoid rust and breakage.

Compliance
Comply with local building codes (such as fire prevention and earthquake resistance requirements), and provide a test certificate for commercial use.
