The LR Strand is made up of seven wires, six outer wires twisted around a central wire with a uniform length of lay in each layer. The strand specifications have been listed below.
In order to serve our clients engaged in the construction and foundation piling business, Rocksmith now stocks Low Relaxation (LR) strands on an ongoing basis.
We stock 9.5mm, 12.7mm, 15.2mm and 15.7mm strand. Our products comply with the Australian Standard AS/NZS 4672 "Steel pre-stressing materials".
Rocksmith also stocks high quality galvanized flat ducts used for aiding post tensioning of concrete structures. Post tensioning is a technique for reinforcing concrete.
It is a form of prestressing the concrete. Prestressing simply means that the steel strands are stressed (pulled or tensioned) before the concrete has to support the service loads.
LR strands are passed through these galvanized flat ducts and concrete is poured onto them as well as the rebar framework. Once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete.
Rocksmith stocks galvanized flat ducts or sheathing ducts having the following dimensions 70 mm W x 20 mm H x 5.8 m L The thickness of these ducts is 0.4 mm
The galvanized flat ducts are available with Rocksmith at the most competitive price rate. We also have the logistic ability to deliver these ducts to the remote interiors of Australia.
