1. Description of Murfor®
Murfor is a prefabricated wire reinforcement for masonry to be embedded
in the horizontal bed joints. Its unique shape combined with its material
properties increases the tensile strength of the masonary.
1.1 Description
Murfor®
consists of two longitudinal wires which are welded to a continuous
zig-zag cross wire to form a lattice truss configuration. The cross
wire is welded to the sides of the longitudinal wires so that the overall
thickness does not exceed the diameter of the longitudinal wires.The
longitudinal wires are indented to improve the bond with the mortar.
1.2 Quality
The steel used in the manufacture of Murfor is either high tensile,
in accordance with BS4482, or austenitic stainless steel, grade 304,
in accordance with BS1970: Part 1: 1983.
The characteristic tensile strength of both the high tensile and stainless
steel wires is 500N/mM2.
The shear resistance of each weld connecting the cross wire to the
longitudinal wires is at least 2.5kN.
1.3 Standard Types and Dimentsions
Murfor® reinforcement is manufactured in varios widths, shapes
and finishes to suit the application.
