Threading 500PLUS REBAR
The design tensile strength of fine-threaded 500PLUS REBAR (φNtf ) can be determined in accordance with AS4100 Steel Structures. Based on the results of testing, fine-threaded 500PLUS REBAR has reduced nominal yield strength equal to 75% of the nominal yield strength (500 MPa) and a reduced nominal tensile strength equal to 85% of the nominal tensile strength (540 MPa) based on the thread stress area.

It follows that OneSteel 500PLUS REBAR, when cut with AS1275 metric threads and fitted with AS1112 Property Class 5 nuts, has the values of design tensile strength (φNtf ) specified in the adjoining table. These design tensile strengths are based on the effective tensile stress areas from AS1275, a strength reduction factor φ = 0.8, and a nominal tensile strength equal to 0.85 x 540 = 459 MPa.

Bending & Rebending 500PLUS REBAR
Bending/Rebending & Welding Practice Notes
A number of situations may arise where bars must be bent or rebent on site, or where pre-bent bars must be straightened. For smaller diameter bars (i.e., 10, 12 & 16mm), this is preferably performed at ambient temperature, as this has the least effect on steel properties. Please observe the following: • The initial bend should be performed around a mandrel or former of diameter specified in the relevant code, and generally not less than 4db. • Rebending or straightening should be performed using a powered bending tool, or a pipe with internal diameter not greater than 2x the nominal bar diameter. • Do not use impact blows to bend or rebend the steel. • Take care to minimise surface damage and visually inspect rebent area for cracks.
For larger diameter bars, the application of heat (e.g. from an acetylene flame) may be used to reduce the bending force, but a reduction in bar strength may result. Further details on bending/rebending & welding 500PLUS REBAR can be found at www.reinforcing.com www.reinforcing.com A pipe must not be used to make the initial bend, or to rebend back past the straight position. Rebending of bars that have been bent prior to galvanising is not recommended, as cracking on the inside of the original bend may result.

Heating & Welding 500PLUS REBAR
o
iv) if during heating the temperature of the bar exceeds 450 C, the design yield strength of the steel after bending shall be taken as 250 MPa.
After heating, the resulting ambient temperature properties of reinforcing steels may be significantly altered. This is an important consideration if heat has been applied to assist with bending bars, through welding, or the effect of fire. To effectively manage the temperature control during the heating or welding process the use of temperature control crayons is recommended.
Welding
Heating
Heating should be avoided if the original bar properties are required. Bending should always be around a former of the appropriate size (refer processing to AS3600). AS3600 states in clause 19.2.3.1 that reinforcement may be bent hot, provided that: i) the steel is heated uniformly through & beyond the portion to be bent o ii) the temperature of the steel does not exceed 600 C iii) the bar is not cooled by quenching
500PLUS REBAR produced by the TEMPCORE process and microalloyed 500PLUS coiled rebar has a maximum carbon equivalent (Ceq) of 0.44. max and, as such, requires no pre-heating prior to welding. Pre-heating is not required when welded in accordance with the AS/NZS1554 part 3. Hydrogen controlled electrodes will be required for all weld types, and matching strength electrodes will be required for butt welds. Note: Some types of welded splices can reduce the ductility of the connected bars.

500PLUS BAMTEC Reinforcing in a Roll Benefits BAMTEC is the world’s fastest steel fixing system. It involves designing and prefabricating reinforcing steel “carpets” to a wide range of shapes and sizes. Individual rebars are welded to flexible steel straps, which can connect up to hundreds of bars together, and the carpet is rolled up for handling and transport. The carpets can contain different types and sizes of bars, have bars at different spacings and can accommodate complex shapes and penetrations. When needed on site, the carpet is simply lifted into place and unrolled onto continuous bar chairs.
• Super-fas Super-fastt construction • Save up to 80% on steel-fixing costs • Ideal for suspended slabs, slab on ground, CRCP and tilt-up panels • Improves cost effectiveness of slab construction • Variable spacing and bar diameters available • Improved accuracy and quality • Less material waste and scrap • Design assistance available • Less bending and carrying • Easier chairing and no bars to sort • Simpler marking plan
Size limits The minimum diameter of bar which can be used with BAMTEC is 10mm. The largest diameter used is 32mm Class N 500PLUS REBAR. The minimum bar spacing is 50mm up to a maximum spacing of 400mm. BAMTEC comes in widths from 1.8m minimum to 15m. Maximum mass per carpet is approximately 1.6 Tonne.

HAUNCHMESH Composite Shear Reinforceme Reinforcement nt
HAUNCHMESH HAUNCHMESH STRAIGHT – 500MPa for Fielders’ KF70 or Lysaght’ Lysaght’s W-DEK
• HAUNCHMESH is a composite beam innovation made under exclusive licence by OneSteel Reinforcing. • Welded studs need to be spaced longitudinally in singles or doubles to match the spacing of the transverse bars in standard HAUNCHMESH STRAIGHT panels • Controls longitudinal splitting, prevents lateral punch-out of concrete in haunch and ensures welded studs arranged in singles achieve solid-slab strength status.
• Minimum concrete haunch width with split decking equals 220mm (KF70) or 240mm (W-DEK) at base, and studs must be centred in haunch. • Availale for KF70 with unsplit decking and narrow 136mm wide haunch • Type Type 1,2 or 3 longitudinal shear reo (Clause 9.7 of AS 2327.1)
