BS 1722-2:2020 - TC ExComm - SET

• 91.090 External structures

This part of BS 1722 specifies requirements for the construction and installation of rectangular wire mesh fences, line wire and dropper strained wire fences and hexagonal wire netting fences.

This British Standard aims to establish minimum requirements for materials and workmanship for the more common types of fence in order to ensure satisfactory service for the client, and to assist manufacturers and installers by eliminating unnecessary minor variations in the demands of clients.

Requirements are specified for sizes of components, together with the permissible tolerances. These are minimum requirements and it is normally acceptable to use larger sizes, except if this could adversely affect the fitting of components or if replacement parts are required to match up with those already present.

Requirements are specified for protective treatments. However, general maintenance requirements of the fence after installation are outside the scope of this standard.

The typical dimensions for lengths of posts and struts and foundation sizes specified are for normal ground conditions. This part of BS 1722 does not cover conditions of particularly firm or soft ground, where other lengths or foundation sizes might be required.
