30、, Uncontrolled Copy, (c) BSI prEN 10223-4:2008 (E) 4 1 Scope This Part of 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
31、 panels and coatings, properties and tolerances. The 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
32、 referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 1461, Hot dip galvanized coatings on fabricated iron or

36、oses of this document, the following terms and definitions apply. 3.1 welded mesh fencing fencing made by electrical resistance welding either: a) zinc-coated or zinc alloy coated wires; or b) bright wires which are subsequently coated after welding either with zinc or zinc alloy. In both cases, the
37、 wire may or may not be crimped. The welded mesh may or may not be subsequently coated with an organic material.

38、 and leading edge of wires (see Figure 1) 3.3 mesh size spacing of line wires followed by the spacing of cross wire e.g. for 50 mm line wire spacing and 25 mm cross wire spacing the mesh size is 50 x 25 3.4 line wires wires running in the longitudinal direction parallel with the length of the roll o
39、r panel (See Figure 1) 3.5 cross wires wires running in the transverse direction (See Figure 1) NOTE On erection of the fence, the cross wires become vertical. 3.6 panel welded mesh produced in flat form to specified dimensions or cut from rolls of welded mesh. Panels are produced either with overha
40、nging edges or with flush cut edges Key 1 Cross wires 2 Line wire spacing 3 Cross wire spring 4 Line wires Figure 1 Example of mesh Licensed Copy: London South Bank University, South Bank University, 31/01/2009 04:08, Uncontrolled Copy, (c) BSI prEN 10223-4:2008 (E) 6 4 Information to be supplied by
41、 the purchaser The following information shall be supplied by the purchaser 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 widt
42、h of rolls or size of panels; h) the class of zinc or zinc/alloy coating and 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 str
43、ength of line wires and cross wires if different from each other; k) whether 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) inspection documentation requirements;
44、 o) agreed quality characteristics for testing (see clause 7). 5 Manufacture 5.1 Base metal 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 wir
45、es which subsequently after welding are either zinc or zinc alloy coated to EN 10244-1 and EN 10244-2 class A; or b) zinc or zinc alloy wire coated to EN 10244-1 and EN 10244-2 class A, unless otherwise agreed at the time of enquiry and order. Where requested by the purchaser the welded mesh fencing
46、 shall be subsequently coated with an organic material to EN 10245-1 and EN 10245-2 or EN 10245-3. The type and colour and any other criteria shall be given on the order.

47、8 (E) 7 5.2.2 Panels Panels shall be produced by either: a) cutting from zinc or zinc alloy coated rolls; or b) by electrical resistance welded bright wires and subsequently zinc or zinc alloy coated to EN ISO 1461. No bare patches shall be permitted. When requested by the purchaser the welded mesh
48、fencing shall be subsequently coated with an organic material to EN 10245-1 and EN 10245-2 or EN 10245-3. The type and colour and any other criteria shall be given on the order. 5.3 Welding The mesh shall be produced by electrical resistance welding at every line wire/cross wire intersection. NOTE 1
49、 The line and/or cross wires may be crimped. NOTE 2 Depending on the application, the mesh spacing throughout the fencing may be the same, as in 50 x 50 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 wires may be different from the diameter of cross wires. 6 Requirements 6.1 Tensile str
