GI BINDING WIRE 21G

21-Gauge Galvanized Iron (GI) Binding Wire is a premium-grade, low-carbon steel tie wire engineered for high flexibility and long-lasting corrosion resistance. Processed through a careful thermal annealing stage, this wire provides optimal pliability, allowing manual twisting and tight knotting without snapping. The surface is evenly coated with a protective zinc layer via electro-galvanization or hot-dip processing, making it highly resilient against moisture, oxidation, and harsh atmospheric conditions common in coastal regions.

Technical Specifications

• Material Composition: Low-carbon steel core (SAE 1006 / SAE 1008 or equivalent)
• Wire Gauge Size: 21 Gauge (BWG / SWG standard)
• Diameter: 0.80 mm to 0.83 mm
• Tensile Strength: 300 to 550 N/mm² (Soft-annealed temper for easy hand-tying)
• Surface Treatment: Zinc-coated (Galvanized); available in Electro-Galvanized (bright finish) or Hot-Dip Galvanized (heavy-duty protection)
• Elongation: ≥ 15% – 25% (Ensures high structural flexibility under load)

Primary Applications

• Reinforcement Steel Tying: Crucial for securing rebar joints, links, and heavy stirrups in civil construction.
• Plastering & Ceiling Frameworks: Extensively used for mounting and binding Plaster of Paris (POP) mesh, expanded metal lath, and lightweight wire netting.
• General Bundling & Fencing: Ideal for commercial packaging, securing boundary chainlink fences, and industrial strapping.
• Agriculture & Landscaping: Used for establishing vine supports, plant training, and organizing protective crop netting.
