Technical Data

In addition to providing customers with steel reinforcing solutions across the entire building and construction industry, Liberty OneSteel Reinforcing have an experienced and highly skilled team of schedulers, engineers and technical service personnel who can offer advice on the most suitable reinforcing solutions, appropriate Standards  and guidance on the technical aspects of reinforcing steels. Liberty OneSteel Reinforcing also provides an extensive range of technical resources such as REODATA 4.1, conference paper and design booklets as well as product application advice which are able to be utilised by structural and civil engineers and engineering students.


REODATA is a comprehensive technical booklet containing information on reinforcing standards, information on how to use reinforcing products, and also the range of Liberty OneSteel Reinforcing specialised solutions to save time, cost and resources.

With 62 pages of comprehensive data, the REODATA technical guide aims to provide information and references to assist engineers and specifiers with all aspects of steel reinforcing. Comprehensive products details include the latest information on 500PLUS® REBAR and ONEMESH® steel reinforcement as well as easy-to-read reference tables on reinforcing bar and mesh with details on how to bend, rebend, weld and join reinforcing steels.

REODATA is available free from all Liberty OneSteel Reinforcing branches or a copy can be requested by emailing

Bending, Rebending, Welding and Machine threaded bar applications advice

Application of 500PLUS Reinforcing Bars has a number of guidelines, which should be adhered to, that comply with Australian Standards. The document outlines the considerations and specifications for bending, welding and temperature effects of reinforcing steels. This also includes recommendations for machine threaded bars to show the minimum effective yield stresses and tensile stresses for optimum use.

REO Calculator

The REO calculator has been developed to determine the nominal areas of main rebar and reomesh manufactured to AS/NZS 4671 - 2001 : Steel reinforcing materials, by Liberty OneSteel Reinforcing. The cross-sectional area of ribbed bars is taken as the calculated area of a circle having the same diameter as the bar size to three significant figures. This calculator assists in determining the correct spacings and sizes.
