High Yield Steel for Reinforcement of Concrete
Key features of the system:
- Fully threaded bar - can be cut and coupled at any point.
- Robust thread - ideal for use on construction sites
- Coarse pitch threadform with two flats ensures self-cleaning of thread
- Fully galvanized systems - galvanized threadbars and accessories also available from stock.
The GEWI® Threadbar System consists of high yield GEWI® screwable steel and corresponding coupling and anchoring accessories, which enable safe and easy connections between anchorages made of GEWI® steel. In accordance with the German approvals Z-1.5-76, Z-1.5-149 and Z-1.5-2.
GEWI® Steel High Yield Threadbar is a high tensile alloy steel bar which features a coarse right-hand thread over its full length. The system has proved its efficiency around the world and ofters versatility in a range of applications. Manufactured in accordance with the German Certificate of Approval issued by the Deutsches Institut für Bautechnik, the system also ofters general conformance with BS 4449 : 1997 (Carbon Steel Bars for Prestressing of Concrete).
The minimum specified characteristic yield strength is 500 N/mm2 for bar diameters 16 - 50 mm and 555 N/mm2 for the 63.5 mm diameter bar. 16 - 50 mm bars can be welded using appropriate industry practices relative to the carbon content of the steel. Welding of the higher grade 63.5 mm diameter bar is not recommended.
