Wire bar chairs provide support for the ducts which criss-cross through concrete slabs for post tensioning. Straten Group caters for a wide range of wire bar chairs to suit 70mm and 90mm flat ducts, which are available in a range of heights to accommodate ducts set in a wave-like profile.
The PT bar chairs are designed for easy clip on/ tie-on installation and come with plastic coated feet to prevent corrosion. To maximise concrete cover, the clip-on wire bar chairs are only 3-5mm above the duct. Straten Group also stocks Metal Base Plates for chair support on soft surfaces.
