1, railing heights. According to the design specifications. 1) not below the balcony railing of the low-rise, multi-storey residential real 1.05m, high-rise, high-rise balcony railing height should not be less than 1.10m. [The residential design code (GB50096-1999) 3rd.

[The residential design code (GB50096-1999) 3rd.
