THREADBAR®
The original THREADBAR® is hot-rolled, high strength steel with two flat sides in the thread pattern that allow gripping and turning of the bars with a crescent wrench. The flat sides facilitate self-cleaning with each stripping operation. DYWIDAG THREADBAR® and accessories have been used around the world for decades.
Benefits
Fast
The continuous coarse threads on all DYWIDAG Form Tie components mean quick installation and stripping. The threads resist handling damage and remain threadable even when dirty or rusty.
Strong
DYWIDAG’s high load capacities allow greater spacing for fewer ties and lower labor costs.
Light
DYWIDAG ties are 50% lighter than conventional ties. Their lightweight and high strength features save on shipping and labor costs.
Versatile
The bars are available in mill lengths and can be cut to fit and/or spliced at any point without reduction in strength or threadability.
