ULTRAshell Band Beams

Ultrashells are precast, pre-stressed, beam shells which are used to provide a fast, cost effective solution to any band beam design. Ultrashell bands can be easily connected to concrete columns, steel columns, piers or load bearing walls.

Band depths of 290mm to 600mm, and widths of 600mm up to 2400mm are possible. Reinforced Ultrashell beams can span up to 11m, with greater spans possible via the addition of Post Tensioning cables.

All shell beams are produced using a specially designed 65 MPa concrete mix and are pre-stressed with 9.5mm low-relaxation steel strands under the strictest ISO 9001 quality controlled conditions.
