#11 Grade 90 All-Thread Rebar

Protection
Williams new #11 Grade 90 All-Thread Rebar allows for higher levels of design stress or designs with less anchors for critical applications such as wind energy foundations and tieback anchors, than other types of conventional rebar. It is manufactured from a carbon steel with excellent elongation and reduction of area properties. At the same time it is more economical than high strength prestressing bars or special production alloy steel bars. The rugged right hand, cold rolled, thread/deformation pattern assures a concentric stress in the thread form of the components while providing the highest possible grout bond area for the rebar.

Williams steel bearing plates are standard with a round hole for non-grouted anchors. Also available are dished plates for use with spherical hex nuts and keyhole plates which provide free access for grout tube entry. Bearing plates are customized for each application. Plate dimensions should be specified around the parameters of the project. In addition, corrosion protection should be considered along with specifying hole diameter and bar angle. Stainless steel plates available upon request.
