What is the diameter and length of the oblique drift safety net for high-rise buildings?

The safety net is not less than three meters.

The first building protective net is usually hung on the second floor (3 ~ 4m high), and then a movable building protective net (GB5725-85) is hung every 6 ~ 8m. Multi-storey or high-rise buildings should be equipped with fixed building protection nets on the second floor and fixed safety nets on every fourth floor.

The distance between the net and the surface of the object below (or on the ground) shall not be less than 3m. When hanging the building protective net, it should be considered in advance that there should be a retractable movable building protective net at the temporary position where feeding and discharging are needed. When hanging materials, the net should be put away and restored to its original state immediately after use.
