Fletcher Reinforcing supplies the reinforcing steel and mesh that provides the strength to New Zealand s buildings and infrastructure. Mesh is available from national Building Merchants or our branch network to construction sites and builders throughout New Zealand. Fletcher Reinforcing offer a range of New Zealand manufactured mesh that complies and is tested to all current Standards. The range covers both Super Ductile mesh in grade 500E wire and a proven range of hard drawn mesh in the sizes required by builders and contractors throughout New Zealand. The Department of Building & Housing now states the reinforcing requirements for concrete slabs-onground of buildings built in accordance with NZS 3604: 2011, have a minimum of 2.27 kg/m2 of Grade 500E reinforcing mesh fabric which conforms with AS/NZS4671:2001. Super Ductile 500E meets these requirements: Grade 500E (seismic) as per AS/NZS 4671:2001 ield stress (MPa) >500 <600 Elongation >10% Tensile Ratio % >1.15 <1.40 Weight per m2 complies with NZS 3604:2011 (min 2.27kg/m2) Weld Shear Strength >5.9 kn External testing is completed by SGS, the world s leading inspection, verification, testing & certification company Hard drawn mesh is specified under NZ3421:1975 (see next page for more detail). Fletcher Reinforcing offers a range of mesh sheet sizes and centres to meet the needs of typical New Zealand applications. Our range covers standard sheet sizes of 4.65m x 1.97m through to our larger economical sheets which are 6.15m x 2.42m. Centres are either 150 x150mm or the step through option of 300 x 300mm.

New Zealand Standards Standards New Zealand controls the preparation and publishing of all Standard Specifications and Codes of Practice in New Zealand. They are developed by expert committees using a consensus-based process that facilitates public input. The relevant Standards listed below, specify the mechanical properties of the steel wire used for concrete reinforcement, the fabrication of the welded fabric and the methods of application in respect to concrete reinforcement. Visit www.standards.co.nz for more information. NZ3421:1975 Specification for Hard Drawn Mild Steel Wire for Concrete Reinforcement The Standard requires the following tensile properties:- NOMINAL DIAMETER (mm) MINIMUM 0.2% PROOF STRESS (MPa) TENSILE STRENGTH (MPa) Minimum Maximum Up to and including 3.15 485 575 855 Over 3.15 485 575 775 NZ3422:1975 Specification for Welded Fabric of Drawn Steel Wire for Concrete Reinforcement This Standard requires a minimum average Weld Shear load Where the longitudinal wire diameter is in the range 11mm to 3.15mm and the longitudinal to transverse wire diameter differential does not exceed 3mm, the minimum average shear value in Newtons shall be not less than 240 multiplied by the cross-sectional area of the longitudinal wire in square millimetres, and states requirements of The distance between centres of two adjacent wires shall not vary by more than 7.5 percent from the exact pitch. If fabric is required to be cut to specific dimensions, the tolerance shall be as follows : 5 Metres and under +25mm over 5 metres +0.5% NZS3101:2006 Code of Practice for The Design of Concrete Structures This Standard lays out the development length and lap-splice requirements for plain wire mesh and deformed wire mesh, and is the basis of any pertinent calculations or recommendations given in this Product Guide.
