A reinforced concrete slab is a material that is very strong in compression, but virtually without strength in tension. To compensate for this imbalance in a concrete slab's behavior, reinforcement bar (also known as rebar or reo bar) is cast into it to carry the tensile loads.

Common reinforcement bar is supplied with heavy outward ridges to assist in binding the reinforcement to the concrete material mechanically - this is referred to as deformed bar - most concrete beams and footings are specified using this type of bar, being held together and in place with reinforcement bar fitments, which are also referred to as ligatures or stirrups). Even the reinforcement mesh sheets are fabricated using deformed bars nowdays to give them the same added strength.

Most structural engineers will specify prefabricated bars of varying diameters and lengths, shapes etc. and lay them at varied distances apart specific to your particular job needs. As such, reinforcing bars come in a range of differing diameters.

Reinforcement bar types and sizes

 

  • Round mild steel reinforcement bar - R6  R10  R12  R16  R20  R24  R28  R33
  • Deformed reinforcement bar  - N12  N16  N20  N24  N28  N32  N36
  • Stock lengths of reinforcement bar - up to 12 metres
  • S12 Pool Steel - Mild steel bars (not tempcore) that is very easy to bend by hand 
  • Processed reinforcement bars - custom cut and bent to required needs
  • Dowel Bars - precut, often galvanised round bars used when one slab joins another
  • Galvanising - Plain Reinforcement Steel bars can also be supplied galvanised

 

*Deformed Bar was previously called Y-Bar eg: Y12, Y16 but through product improvements the tempcore strength was increased (now 500Mpa) and is now denoted as N-Bar as listed above
