Bar & Mesh Support Chairs

PSA has a range of bar chairs (reinforcement supports) to suit virtually any application. The chairs can be singular or continuous, with or without clips; suitable for slab on ground or formwork and sizes up to 245mm high. They are available in plastic, concrete or wire, depending on whether you wish to support the bottom or top layers of reinforcement, or between the two. If you`re not sure tell us your application and we can recommend a type and size to suit.

  • Continuous Deck Chairs

    Continuous Deck Chairs

    The plastic deck rail is a continuous spacer for formwork applications. Designed with sets of vertical legs at approximately 75mm centres and another central leg in between the sets; the deck rail is strong and stable, yet provides minimum exposure. Another feature is the male and female connection at either end to join rail on rail to any given length. Once connected the clip will not separate; a must for large projects. Clipping bar chairs onto the reinforcement or “chairing up” after the reinforcement has been placed is now eliminated. Ideal for suspended decks, precast or tiltup panels, in situ and precast beams and slabs on blinding concrete. Available in heights from 25mm to 100mm in 5mm increments.

    Note: CDR025 - CDR075 designed so that it can be snapped in half, which will create two 550mm long sections

  • Snake Spacers

    Snake Spacers

    The Snake Spacer provides a quick, easy and economical method of supporting between two layers of reinforcement in concrete slabs and panels. The spacers are supplied in an effective length of 2.0 metres and range in size from 40mm up to 150mm.

    The Snake Spacer is perfect for any precast application that calls for double reinforcement. By sitting on top of the bottom layer of reinforcement it eliminates exposure that plastic and wire chairs often leave. Ideal also for slab on ground where double reinforcement is required.

    Other sizes available upon request.
