Black Annealed Wire
Everyday performance for professional rebar tying
TEK Black Annealed Wire is engineered as a reliable choice for professional contractors. The annealing process is designed to deliver consistent softness and controlled tensile strength, so ties are intended to form cleanly and hold securely. Loaded on the TEK dual-chamber spool, the wire is developed to feed smoothly through the tool — helping reduce downtime on demanding pours.
Built on the TEK dual-chamber platform
Low-carbon steel drawn to a precise 1.0 mm gauge, then furnace-annealed to achieve a controlled soft temper. The dual-chamber spool architecture keeps the wire under constant tension in the tool, eliminating the tangles that stall production on single-coil systems.
