Notes:
1. In general the RT550 and RT800 are ideal for soil nailing applications because they have an excellent range of accessories and the most beneficial yield properties.
2. RT1050 is widely regarded as the best grade for post-tensioning and other applications where exceptional tensile strength coupled with good elacticity is required.
3. Other grades have various properties which make them ideal for general reinforcement and formwork ties.
