How to Choose Tie Wire?
Four types of tie wire rolls: choose the appropriate one based on the application scenario and cost.
| Process | Advantages | Disadvantages | Typical Applications |
Black Annealed Wire | Low-carbon steel, annealed | Soft, easy to bend | Highly prone to rust; rust residue can damage rebar tiers; poor durability | Indoor projects, short-term projects |
Galvanized Wire | Annealed wire with zinc coating on surface | Anti-rust, enhanced durability, most cost-effective | — | All ordinary outdoor/indoor reinforced concrete projects |
Stainless Steel Wire | Made of stainless steel (e.g., 304) | Excellent corrosion resistance, long lifespan, high strength | High cost, high hardness, not friendly to rebar tier (accelerates wear of rebar tier parts) | Coastal structures, chemical plants, sewage treatment plants, permanent underwater structures |
PVC-Coated Wire | Galvanized wire wrapped in a plastic layer | Dual rust prevention (zinc layer + plastic), chemical corrosion resistance, color options | Expensive, plastic layer may wear down; once damaged, rust-resistant properties will decrease | Often used for applications requiring aesthetics or specific chemical corrosion resistance, such as guardrails, aquaculture nets, landscape bundling |
