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
Qijie metal joint reinforcement products conform to:
ASTM A951 (Standard Specification for Steel Wire for Masonry
Joint Reinforcement)

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
