ROMTECH® Lattice Girders

Overview

ROMTECH® Lattice Girders

ROMTECH® Lattice Girders supplied by InfraBuild Construction Solutions (formerly LIBERTY OneSteel Reinforcing) are an innovative tunnel support system of rebar lattice girders. ROMTECH® is suitable for use in hard or soft ground conditions and complies with all relevant Australian Standards.

ROMTECH® provides high strength-to-weight ratios and is available in a wide range of sizes that can accommodate complex radial geometries. When used with mesh or fibre reinforced concrete, they form a continuous reinforced concrete shell, which can support both temporary and permanent loadings. Lightweight and easy to handle on-site, ROMTECH® reduces shotcrete cycle times and shadowing. 

ROMTECH® Lattice Girders are available in a wide range of cross-sectional sizes and designs.
