High yield coil

Celsamax

Celsa’s innovative new reinforcing coil, Celsamax, provides significant performance and productivity benefits in decoiling, bending, and, potentially, even in transport and storage. Celsamax is a high yield coil with more constant, consistent material characteristics and guaranteed mechanical properties. Its geometric design means that coil ribs experience significantly less damage during rolling and subsequent cold processing, preserving the height of the rib and thus improving the bond performance with concrete. In addition, the wear on straightening machine rolls is considerably reduced when producing cut and bent material, resulting in prolonged roll life.

Due to the hot spooled production process, which allows spooling without any twisting of the material, coils are easier to straighten with no bending out of plane when decoiling. The lack of spring in the material and the fact that there are no welds within the coil means that Celsamax is safer to work with than standard contistretch material.

The fact that there is potential to produce Celsamax in larger coils has numerous productivity and logistical advantages. Coils of greater weight allow for greater decoiling speed during subsequent cold processing, with fewer changeovers and less adjustments needed to straightening machines. Furthermore, larger, heavier coils result in lower rolling, transport and storage costs. Tighter tolerances in the coil geometry result in more compact coils which are easier and safer to transport, stack and store, with less space needed per coil.

Celsamax is available in coils of 8mm, 10mm, 12mm, 16mm and 20mm diameters, with the potential for availability in larger diameter coils up to 25mm as demand dictates. Compliance with British (high ductility grade B500C reinforcing coil to BS 4449:2005 + A3:2016) and European standards is guaranteed, whilst fatigue and cyclic load performance are also guaranteed to exceed current standard requirements. Celsa is confident that Celsamax will satisfy the highest levels of quality demanded by our customers and industry alike.
