This part of BS 1722 specifies requirements for chain link fences and gates and gateposts for use with chain link fences. The gates specified are steel with a provision for chain link infill or other infill if required by the client.<\/p>\n
This British Standard specifies requirements for fences up to 3.60 m in height with a chain link mesh infill. For other security fences, refer to BS 1722\u201110, BS 1722\u201112 and BS 1722\u201114, and for chain link mesh specifications refer to BS EN 10223\u20116.<\/p>\n
This British Standard is divided into requirements for the material components for fences and for installation of the fences. This standard also specifies requirements for protective treatments. However, maintenance requirements for the fence after installation are outside the scope of this standard.<\/p>\n
This British Standard specifies requirements for sizes of components. These are minimum requirements, and it is acceptable to use larger sizes, except where this could adversely affect the fitting of components, or if replacement parts are required to match with those already present.<\/p>\n
Ground conditions might indicate that a variation in the length of a post or strut, or the depth to which these can be set, is desirable. The posts and struts and setting depths specified in this part of BS 1722 are intended for use in normal ground conditions, but if special conditions exist that warrant variations in the specification, e.g. the ground is softer or firmer than usual, such a change needs to be agreed with the specifier.<\/p>\n
