Precast concrete products. Elements for fences (British Standard)
This standard covers prefabricated concrete elements which can be used together or in combination with other elements to erect fences. The current concrete elements include posts (reinforced, prestressed or post-tensioned concrete), solid or base or open panels, slabs, rails, spurs, struts and gravel boards. The purpose of this standard is to define: a) the terminology; b) the main guidelines needed for concrete elements which are well suited to their intended use.
