Balcony guardrail is a beautification and protection facility for the outer edge of the balcony, which is made of alloy pipes through welding or assembly. The common low windowsill is about 0.5m above the ground. If a 0.4m guardrail or fence is added close to the inner wall, it must meet the protective measures required by the specification. If the windowsill top is too large, such as a bay window, children often stand on the windowsill to look out, and the user must also stand on the windowsill to open the window. At this time, the height of the guardrail attached to the windowsill should reach 0.9m.

Whether the balcony guardrail meets the standard is directly related to the safety of the family. What are the safety standards?

The mechanical properties of balcony guardrail shall comply with the following table: horizontal load (n/m) vertical load (n/m) soft weight impact performance 500 (residential building) 1000 (public building) 500 2000 the deflection deformation of the cross bar shall not be greater than 1/120 of the length of the cross bar, and all structural members shall not be damaged. All components shall not fall off, break or have permanent deformation that will affect the use.

The height of balcony guardrail shall not be less than 1.05M when the height of ground floor, multi-storey residence or free space is less than 24m; When the height of medium and high-rise buildings, high-rise buildings or overhead buildings is more than 24m, it should not be less than 1.1m, and the height of high-rise residential buildings should not be less than 1.20m; The height of protective railings on balconies and roof platforms of kindergartens, primary and secondary schools and special activity places for children shall not be less than 1.20m. Balcony handrails shall be designed to prevent children from climbing, and the vertical clear distance of handrails shall not be greater than 0.11M.

Balcony railings in residential buildings, nurseries, kindergartens, primary and secondary schools and special activity places for children must be constructed to prevent children from climbing. When vertical bars are used as railings, the clear distance between the bars shall not be greater than 0.11M.

In public buildings such as cultural and entertainment buildings, commercial service buildings, sports buildings, garden landscape buildings, etc., where children are allowed to enter the places for activities, when vertical bars are used as balcony railings, the net distance between the bars shall not be greater than 0.11M.

The height of balcony handrail shall be calculated from the vertical height from the floor or roof to the top surface of the handrail. If there is a treadable part at the bottom with a width greater than or equal to 0.22m and a height less than or equal to 0.45M, it shall be calculated from the top surface of the treadable part.

Balcony railing structure must be firm and safe. When a flower pond is added to the railing, the problem of water discharge from the flower pond must be solved. Fall prevention measures must be taken at places where flower pots may be set.
