What Is Tie Wire Made Of?

Ever watched tradies on a construction site twisting that thin wire around rebar and wondered what exactly they’re working with? That’s tie wire – the essential support holding together the backbone of concrete structures across Australia. After 50+ years in the Australian steel industry, we know firsthand how this humble wire makes or breaks a solid construction job. 

What is Tie Wire Made Of and How is it Created?

Rebar tie wire is basically annealed, low-carbon steel wire that bends easily without snapping, yet has the grunt to keep reinforcement bars firmly in place when concrete’s being poured. Annealing is a process that gives tie wire its perfect balance of strength and flexibility that builders love.

To make this iconic product, steel wire is heated to very high temperatures and then cooled slowly. This changes the metal’s properties and softens the steel so it’s more pliable. Construction workers need the tie wire to be easy to twist and manipulate without breaking, but strong enough to hold rebar properly in place. Tie wire is 1.57mm in diameter and can have a black, galvanised, or stainless steel finish. Once the wire is ready to go, it is wound onto spools or formed into coils, ready to bind together projects large and small.

What is Tie Wire Used For?

Tie wire serves several helpful functions in construction and reinforcing work. Some of the most common ways our tie wire is used are:

• Securing rebar grids: Tie wire binds intersecting rebar pieces together, maintaining proper spacing and alignment before concrete is poured
• Temporary fastening: It holds reinforcement bars in position until concrete sets
• Mesh reinforcement: It helps secure the wire mesh used in concrete slabs and walls

The malleability of tie wire makes it ideal for quick twisting and securing, allowing workers to rapidly assemble rebar cages and grids with minimal tools. A simple hook tool and the wire itself are all that’s needed to create strong connections between reinforcing components.

Benefits of Steel Tie Wire

Steel tie wire offers many advantages that make it a popular item in construction:

• Strength: Provides secure connections that maintain integrity during concrete pouring
• Flexibility: Easy to manipulate and twist by hand or with simple tools
• Cost-effective: Affordable solution for small or large-scale reinforcement projects
• Versatility: Compatible with various rebar sizes and configurations
• Reliability: Consistent performance across different environmental conditions
• Durability: Holds firm under the pressure and weight of wet concrete
