2. Metallurgy, Annealing Control & Strict Anti-Breakage Quality Assurance
🔥 Continuous Oxygen-Free Annealing
Our Black Annealed Tie Wire undergoes controlled temperature soaking (800°C) inside continuous bell-type oxygen-free annealing furnaces:
- Uniform Tensile Softness: Eliminates internal stress, maintaining consistent 350–450 N/mm² tensile strength for effortless twisting by rebar steel fixers.
- Zero Work-Hardening Breakage: Exceeds 15% elongation test, eliminating wire snapping during heavy rebar cage assembly.
- Light Anti-Rust Lubrication: Micro-coated with non-greasy protective oil to ensure 6+ months shelf life in coastal tropical humidity.
🔨 Grade 45#/60# Quenched Concrete Nails
Unlike inferior low-carbon nails that bend when struck, our Concrete Nails feature:
- HRC 50–54 Certified Hardness: Quenched and tempered high-carbon steel easily penetrates C30–C50 reinforced concrete beams and solid brickwork without bending.
- Deep Fluted Shank Design: Longitudinal spiral flutes provide 35% higher pull-out resistance inside cured masonry walls.

Frequently Asked Questions (FAQ) – Construction Wire & Nails Supply
Q1: What gauge is standard for construction rebar tying wire?
The worldwide standard for rebar tying is BWG 16 (1.65 mm diameter) and BWG 18 (1.20 mm diameter). BWG 16 is preferred for heavy civil bridge and foundation steel fixing, while BWG 18 and BWG 20 are used for lightweight floor mesh and precast tying.
Q2: Can we mix steel coils, pipes, wire, and nails in a single container?
Yes. Sino East Steel specializes in 1x20GP mixed container consolidation. Heavy coils or steel pipes are securely lashed at the container floor with timber dunnage, while boxed nails and palletized wire coils are loaded in the remaining volume under one Bill of Lading, MTC, and Form E/CO.
Q3: What quality test reports are provided with wire and nail shipments?
Every export lot is accompanied by an official Mill Test Certificate (EN 10204 3.1) specifying chemical composition (C, Si, Mn, P, S), tensile strength, elongation percentage, zinc coating thickness (g/m²), and nail hardness test (HRC). Third-party inspection by SGS/BV is supported.
Q4: What is the Minimum Order Quantity (MOQ) and packaging customization?
For consolidated container orders, the MOQ per size is 1 Metric Ton (or 40 cartons of nails / 40 coils of wire). We offer custom brand printing on color boxes, master cartons, and coil tags according to distributor specifications.
