2.hot rolled/cold rolled thread bar.
3.500/550MPa,830/1030MPa,900/1100MPa.

Hot Rolled Threadbar, left hand and right hand are all available, specifications range from 16mm, 18mm, 20mm, 22mm, to 25mm.
MG500, MG450, MG335 threadbar have been researched and developed bu our company. We also have got exclusive selling rights of MG500. The tensile strength, yield strenth and elongation could reach a high standard. These products have a good market in Africa, Australia, and Middle East.

1. The Bar has closely defined mechanical properties which probide consistent performance under long term anchor loading.
2. Unlike strand tendons, the solid anchor has no constructional losses.
3. Supplied in the hot rolled condition which is effectively stress-free.
4. The high ductility and smooth, relatively flat rate of strain hardening ensures a high margin of safety against tensile/shear overload in the case of transverse movements in the rock soil.
5. Resists dynamic loads (e. G. Traffic wheel loads).
6. Preloading to the full working load ensures that the load transmitted to the anchorage medium (rock or soil) is constant, i. E. Live loads are not transmitted to the anchorage medium.
7. A range of chemical and expansion anchors enhance the versatility of the system.
8. Rugged thread is resistant to damage.
9. May be tensioned, released and re-tensioned with ease.
10. Simplicity in applying the pre-stress with jacks, torque wrenches of air operated tools.
11. Recoverable anchor may be removed to simplify later excavations.
12. The rigidity of the anchors makes them easy to install especially in overhead applications
13. High shear bond as deformations are designed for shear interlock with concrete or resin.
14. Transmits the anchor forces efficiently to the grout body without additional fittings.
15. Standard stock lengths may be stored and cut to suit the application. Off cut bars may be used for all standard concrete reinforcement for formwork, starter bars or hangers in underground works.
16. Can be cut and spliced at any point along its length
17. Can be welded.
18. Can be joined end to end using full strength couplings.
