Rajuri 500D Plus

Rajuri Steels, pioneers in adopting new technology to manufacturing rebars, developed the 500D Plus – Added Strength and Ductility bars with a unique composition with high elongation values of 18-25% which makes it further suitable to bear seismic loads efficiently. It is stronger, has higher thermal stability, and shows better bendability.

1. The use of 500D Plus bars results in 15-20% in steel consumption and is thus recommended amongst the community of Structural Designers and Engineers.
2. It ensures greater safety due to high elongation values of 18-25%.
3. It fulfills international quality norms.

Some International Standards:

• German BSt500 of DIN488
• British Gr.450 of BIS 444-1978
• Swiss Topar 500 s of SIA 162
• French FeE50 of NF-A35-016, etc.

It can be used at lesser mandrel diameters so it is preferable in complicated sections at joints of beams and columns.

Any superior rebar resulting from controlled steel making practice will have significantly reduced levels of the impurities Sulphur and Phosphorus. These impurities affect certain properties of steel like fatigue, impact strength, corrosion resistance, etc. In the last revision of the Indian Standard of Rebars (BIS) in 2008, a new superior category of rebar called “D” has been introduced to improve the overall steel quality of Indian steel producers. Complying with the latest specifications, Rajuri steels has introduced a new grade called 500D Plus where the combined level of Sulphur and Phosphorus is restricted to a maximum of 0.075%.

Rajuri Steels has adopted advanced steel-making methods to produce this new product. Reducing the levels of Sulphur and Phosphorus causes the rebar to withstand extreme cold without becoming brittle (because of Phosphorus) and cracking, as well to withstand high temperatures without melting (due to Sulphur).
