Hi-rib lath (high ribbed lath/High Ribbed Formwork) is manufactured
from hot-dipped galvanized steel sheets. has been applied to the
concrete structure of porjects all over the world. As early as
1969, it has tested and verified by British Cement Association of
and many architecture-structure experts in ESPM that it is superior
over traditional template including wooden template, steel temlate
etc. Because it has better stress stress strength and free shape.
It is mostly used as concrete permanent dismantle free template for
civil engineering such as tunnel, bridge, raft-style foundation,
sewer system, subways, retaining wall, nuclear power station,
docks, storang tanks, skysrapers, ocean engineering and irregular
or curved shapes.
Because its meshes and U patterns, it has better anti-stress
capability andforming flexibility than normal metal lath. This
product has excellentengineering quality, construction security and
widely used in tunnels bridges,valve basement systems, sewage
systems, subways, retaining walls, nuclear powerplants, shipyards,
water pools and marine engineering works and high risebuilding
projects and non-regular or bending pattern etc. as concrete
Hi-rib lath is ideal for refurbishing damaged or aged masonry
walls, when a key for rendering is not certain due to
disintegration or softening of the wall face.
Lath should be fixed with apexes of ribs against the wall, edge
ribs of sheets nesting into each other should be wire-tied every
15cm and ends of sheets should be lapped not less than 2.5cm and
nesting ribs securely tied together.
Stainless steel fixings should be used at sufficient intervals to
hold the lath firmly in position.
