23、223-4:2012 (E) 4 1 Scope This European Standard specifies requirements for steel wire welded mesh fencing of which there are many types for a variety of applications. It specifies the general characteristics of welded mesh fencing supplied as rolls or panels and coatings, properties and tolerances.
24、This European Standard covers only orthogonal welded mesh i.e. wire welded at right angles to one another. For welded mesh fencing made from panels the specification covers only panels made from wires not greater than 10 mm. 2 Normative references The following documents, in whole or in part, are no

35、 at the time of enquiry and order: a) number of this European Standard; b) quantity and packaging; c) if for agricultural use or not; d) roll or panel; e) mesh size(s); f) diameters of line and cross wires; g) length and width of rolls or size of panels; h) the class of zinc or zinc/alloy coating an
36、d whether applied before or after manufacture and if required, the adherence and assessment of adherence (wrap specification); i) whether an organic material coating is required and, if so, the type and colour; j) tensile strength of line wires and cross wires if different from each other; k) whethe
37、r or not crimping is required in line or cross wires; l) if applicable, the number of apertures required; m) in the case of panels, whether to be produced with overhangs or cut flush; n) test report requirements; o) agreed quality characteristics for testing (see Clause 7). 5 Manufacture 5.1 Base me
38、tal The base metal of the welded mesh fencing shall be low carbon steel. 5.2 Fabrication 5.2.1 Rolls The welded mesh fencing in roll shall be fabricated by electrical resistance welding either from: a) bright wires which subsequently after welding are either zinc or zinc alloy coated to EN 10244-1 a

43、and/or cross wires may be crimped. Depending on the application, the mesh spacing throughout the fencing may be the same, as in 50 mm x 50 mm security mesh or varying as in the welded mesh fencing for agricultural or general use i.e. decreasing mesh size from the top downwards. The diameter of line
44、wires may be different from the diameter of cross wires. 6 Requirements 6.1 Tensile strength The tensile strength of the line and cross wires shall be in the range 350 N/mm2 to 950 N/mm2. For any delivered lot, the spread of tensile strength shall be within 200 N/m2. NOTE The tensile strength of the
