This part of BS 1722 specifies requirements for steel palisade fences and gates for general purposes (GP) in corrugated and angle pales for heights up to 2.4 m and for security (SP) purposes in corrugated pales for heights of 3.0 m and 3.6 m, all with posts at 2.75 m centres. This standard also covers fences between 2.4 m and 3.0 m in height with components constructed to the SP specification.
NOTE 1 Where greater resistance against penetration is required for fences below 2.4 m in height the SP components may be specified by the purchaser.
NOTE 2 Requirements in this standard for the minimum sizes of fence components are based on a design wind loading, q, (see CP 3-V-2) at right angles to the plane of the fence of 900 N/m employing a shape factor of 1.9 on the net area presented to the wind.
NOTE 3 In situations of extreme exposure or abnormal loading it will be necessary to carry out a special appraisal and for the design criteria to be specified.
