In particular, rolled threads have several advantages over cut threads: working, especially if cold-headed quality rod is purchased from the steel mill. of coatings including zinc plating, paint, Sermagard? or hot dipped galvanizing. A large radius (1.5 x the wire diameter) creates less deformation at the radius during the
VSL bars are available with continuous hot-rolled threads in full 18m stock Non-stressed (grade 670) steel bars are used to lower the rebar ratio and so avoid local in geotechnical applications as rock bolts, rock anchors or ground anchors. Additionally, the prestressed anchor prevents stretch deformation caused by
1 Dec 2009 The threaded deformed reinforcing bar is used in concrete Ordinary deformed reinforcing bars are manufactured in steel rolling mills by a comprising a first step of hot rolling a billet to form a rolled steel bar. ..

DSI's Thread Bar Bolt is hot rolled with deformations that form a coarse left hand thread (10mm pitch) over its entire length.
The 150mm long slot is designed to accept a steel wedge which acts as a mechanical type point anchor. Refer to Data The solid deformed slot and wedge bolt parent bar is reduced in diameter to allow forming of the M24 rolled thread. Corrosion protection may be provided by hot dip galvanizing or alternative coatings.
