Lattice Girders

The Lattice Girders are produced with 2 longitudinal wires in the bottom flange and 1 wire on the top, welded together at regular distances using a smaller diameter secondary wire.

The top and bottom reinforcing wires are produced with SAE 1010 wire rod that after cold rolling acquires the mechanical characteristics of the required reinforcing steel (BSt500M according to DIN488).

Lattice Girders are used mainly as reinforcement of prefabricated slabs and beams where concreting is performed in two stages, offering the advantage of avoiding scaffolding and formwork needed in traditional construction.

Therefore, Lattice Girders are best suited when slab reinforcement is generally light while at the same time fast and no-formwork construction is needed.
