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 wires which subsequently after welding are either zinc or zinc alloy coated to EN 10244-1 and
EN 10244-2 : 2009 , class A : or
b ) zinc or zinc alloy wire coated to EN 10244-1 and EN 10244-2 : 2009 , class A , unless otherwise agreed at
the time of enquiry and order .
Where requested by the purchaser the welded mesh 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.
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 fencing shall be subsequently coated with an organic
material to EN 10245 – and EN 10245-2 or EN 10245-3 . The type and colour and any other criteria shall be given
on the order .
The mesh shall be produced by electrical resistance welding at every line wire / cross wire intersection
The line and / or cross wires may be crimped
Depending on the application , the mesh spacing throughout the fencing may be the same , as
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 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 / mm to 950 N / mm . For any delivered
lot , the spread of tensile strength shall be within 200 N / m
NOTE The tensile strength of the line wires may not be the same as the tensile strength of the cross wires
6.2 Tolerance on wire diameters
The tolerance in diameter of the wires shall comply with the following grades from EN 10218-2
a ) zinc or zinc alloy coated wire to EN 10244-2 : 2009 , class A , tolerance shall be to EN 10218-2 : 2012 , T1
b ) other zinc or zinc alloy coated wire , tolerance shall be to EN 10218-2 : 2012 , T2 ( Table 1 ).
c ) bright wire , tolerance shall be to EN 10218-2 : 2012 , T3 ( Table 1 )
d ) wire coated with an organic material , tolerance shall be to EN 10218-2 : 2012 ( Table 2 )
6.3 Coatings
Zinc and zinc alloy coatings
When coating applies to EN 10244-2 : 2009 , class A , samples taken from the fence shall have the minimum
coating mass requirement reduced by 5 % and where specified the number of dips shall be reduced by one half
minute dip
Additionally , the adherence and wrapping requirements shall be as agreed at the time of enquiry and order
6.3.1.2 Panels
Where pa
panels have been cut from zinc or zinc alloy coated rolls , the coated wire shall comply with the
Where panels have been produced by zinc or zinc alloy coating after fabrication the coated panels shall comply
with the requirements of EN SO 1461 . Where mesh in panels coated after fabrication contains two diameters of
wire , the coating mass shall not be less than the average of the specified minimum values of the two diameters
6.3.2 Organic material coatings
When present , organic materal coatings shall comply with the appropriate part of EN 10245-1 and EN 10245-2 or
EN 10245-3.EN 10223-4-2012 pdf download.
