Original Design

1 layer of #6 rebar at 12"

Helix Dosage

30 lb/yd3

This Steel Plant produces Steel coils that weigh @ 28,000 kg (61,000 lb) each. Once they are manufactured, the operator places them on an exterior slab, stacked three high. The combined weight for which is @ 84,000 kg (185,000 lb). With that type of load, cracking was a major concern.

Tecnor designed the slab on grade with a 30 lb/yd3 dosage of Helix Steel. This provided far greater pre-crack protection while alleviating the need to chair and tie 1 layer of #6 rebar at 12″. Further, the use of Helix Steel enabled a time savings of over 40 days and a quantifiable increase in shear strength, modulus of rupture and durability.
