ASTM A641 Standard Cross Wire Spaced 16" building construction
Ladder Mesh Ladder Mesh Introduction: Ladder Mesh is a prefabricated reinforcement for embedment in the
horizontal mortar joints of masonry.It is manufactured in 10′ 8″ lengths from wire conforming to ASTM A
82 / A82M for cold drawn steel wire.It consists of two or more parallel and deformed longitudinal wires
welded to a perpendicular cross wire spaced 16″ O.C. Out-to-out
spacing is approximately two inches less than the nominal thickness
of the wall.
MATERIAL : Iron wire & stainless steel wire 304/316

Ladder Mesh Feature : * Greatly reduces cracking that can arise from thermal stresses.
This enhances resistance to water penetration, as cracks are
controlled.* Increases lateral flexural strength.* Bonds exterior and interior masonry wythes together in composite
or cavity walls. Also bonds masonry at intersecting walls and
corners* Increases elasticity and performance of masonry walls under
various stresses Ladder Mesh Application: Concrete slabbing, roads, paving, foundations, marine work, bank
strong rooms, partition slabs, concrete block work, asphalt
guttering and so on |
