Aluminum art stair railing design concept

1. The height of the stair handrail ( measured from the front line of the step ) should not be less than 0.90m; the height of the outdoor stair handrail should not be less than 1.05m .

 

2, when the width is greater than 0.20m stairwells, vertical bars handrail clearance should not exceed 0.11 M, to prevent the child fall.

 

3. The net width of the stairway shall not be less than the width of the step, and shall not be less than 1.10m .

 

4. The width of the ladder section is clearly defined in the design of the residential building. In other buildings, the requirements for fire evacuation must be met.

 

The width of the expressive stairs in public buildings is usually too large, but pay attention to the relationship between the setting of the handrail and the width of the step. That is: the stairs should be provided with armrests on at least one side. When the net width of the steps is up to three streams, handrails should be provided on both sides. When four streams are flown, intermediate handrails should be added.
