3 Rebar Lattice girders in conjunction with shotcrete achieve an excellent level of support in tunneling. They consist of steel bars welded together in triangular pattern and they are made to suit the shape of the tunnel. This combined system acts as an armor that provides balanced support and reduced consumption of shotcrete.

ATOM STEEL LTD lattice girder system is totally surrounded by concrete. There are no unconsolidated areas, voids or fissures visible. It represents a complete homogenous composite structure, reduces ground settlement and prevents the ingress of water.
Advantages
ATOM STEEL LTD lattice girder system has been tested and successfully installed in many tunnel projects
It is made from reinforcement steel of B500B quality, with three or four bearing longitudinal bars which are connected by diagonals with appropriate welding. One tunnel arch is comprised of usually five segments and is connected by screws and pipes.
ATOM STEEL LTD produces all kinds of lattice girder tunnel lining in accordance with given specifications and customer designs.
Metal support arches are used in a wide range of applications and with many different soil conditions, offering the advantage of being resistance to compression and traction efforts with a high bending moment. This support technique is suitable for soil conditions that are very prone to subsidence due to the efforts caused by converging soils.
Cold curved beams are used to adapt to the excavation diameter, using the radii required to install them in parallel to the soil. Our entire manufacturing process, from design, bending, welding and dispatch, is certified by:
EN- (CE marking) yand governed according to the ISO quality system.
High-resistance beams that maintain the cross-section dimensions with a low deformation or in which the decompressed soil thickness around the tunnel must be limited within strict parameters. The sectors are joined to form the entire arch using bolted joints between the plates.
