galvanized steel

Tie wire is the soft annealed wire a crew uses to hold rebar in position until the concrete cures. It is a consumable, bought by the coil or by the preformed piece, and it is the one item on a reinforcement package that decides how fast a cage goes together. Steel itself is the backbone of modern construction, as the Britannica overview of steel lays out, and tie wire is what holds that steel in place on site. This page is a selection guide. It covers what the wire is made of, how the gauge systems map to millimetres, which coating suits which environment, and how to size an order.
