What are the design requirements for stainless steel staircase handrails in public places?
stainless steel staircase handrails are support bars for stair guardrails. They are used to support people when going up and down the stairs. They are used to support and assist pedestrians and play a role in relieving fatigue and safety. In the design and production of stair handrails in public places, in addition to its safety performance, its comfort should also be paid attention to. The comfort of the stair railing is related to its height design. If the height of the stair handrails is unreasonable, it will directly affect the comfort of the stairs. The height of the stair handrails is clearly stipulated in the design.
Basic Requirements
1. Material: stainless steel railings, commonly used sus201, sus304 and sus316 stainless steel materials, sus201 and sus304 stainless steel is mainly used indoors, sus316 stainless steel is mainly used outdoors and near the sea, sus304 can also be used outdoors.
2. Classification structure of railings: mainly stainless steel structure, glass stainless steel structure, and wooden stainless steel structure.
3. Height and spacing: when the overhead height is below 24 meters, the railing height should not be less than 1.05 meters, when the overhead height is above 24 meters, the railing height should not be less than 1.1 meters, and the vertical railing spacing should not be greater than 0.11 Meters (not more than 0.1 meters in some countries).
4. Public places: Stairs in residences, kindergartens, campuses, and special activity venues for children and children must be constructed to prevent climbing; cultural and entertainment buildings, commercial service buildings, sports buildings, garden landscape buildings, and other activities that allow children to enter, should be used When building stairs with vertical railings, the net spacing of the vertical railings should also be less than 0.1 meters.
Material Requirements
1. The wall thickness specification, size, and shape of stainless steel railings should meet the design and construction requirements. Generally, the wall thickness should not be less than 1mm. When the steel pipe is used as the column, the wall thickness should not be less than 2.0mm.
2. Wooden handrails are generally processed into finished products with hard miscellaneous wood, and their tree species, specifications, and shapes are in accordance with the design requirements. The wood itself should have a straight texture and consistent color, without defects such as decay, knots, cracks, and distortion; the moisture content should not be greater than 12%. The elbow material generally adopts the handrail material. Connected with a 45-degree section.
3. The thickness of the glass fence should meet the design requirements. Generally, the railing should not be less than 12mm thick tempered glass or laminated glass. The tempered glass should have a retest report for entering the site.
