Hebei Shengtong Metal Products Sales Co., Ltd. is one of the leading manufacturers and suppliers of black annealed coil iron wire in China. If you're going to buy cheap black annealed coil iron wire made in China, welcome to get free sample from our factory. Customized orders are welcome.
Black annealed wire is a low-carbon steel wire softened through a precise thermal process. This treatment gives the wire its characteristic flexibility and smooth finish, making it highly workable for manual bending and twisting. Built for consistency and durability, it is a go-to solution for everyday construction, industrial bundling, and general manufacturing needs.
Our black annealed wire is crafted from high-quality low-carbon steel. Through a controlled annealing process, we ensure the wire is soft enough to handle easily, yet strong enough to hold its shape. It's a reliable, cost-effective choice for rebar tying, heavy-duty bundling, or general DIY projects where you need a wire that won't snap under pressure

Production Process
Production Quality: How We Ensure Performance
We focus on three key stages to ensure our annealed wire meets the high standards required for construction and industrial use:
Precision Drawing: We use high-quality low-carbon rods, cold-drawing them to exact diameters with tight tolerances. This ensures consistent gauge across the entire coil, so you won't face issues with uneven thickness.
Controlled Annealing: We utilize a precision heating process to achieve the perfect balance of softness and strength. This ensures the wire remains flexible for easy twisting and tying by hand, yet strong enough to stay tight without snapping under tension.
Protective Oiling: Every coil is treated with a light, even coat of anti-rust oil. This not only prevents oxidation during transit but also gives the wire that professional, smooth, and clean black finish that's ready for immediate use on-site.
Key Features & Applications
Key Benefits & Practical Applications
Why choose our Black Annealed Wire?
Built for Efficient Tying: Engineered with a "soft-temper" finish, our wire is incredibly easy to twist by hand. Your team can tie rebars faster and with less effort, directly reducing labor fatigue and increasing site productivity.
Reliable Performance: Unlike brittle, untreated wire, our annealed wire provides excellent tensile strength. It stays tight and won't snap during the tensioning process, ensuring your structures remain secure.
Clean and Ready-to-Use: Each coil is treated to prevent oxidation, ensuring a smooth, rust-free surface that is clean to handle on-site.
Common Applications:
Construction: The go-to choice for rebar tying. Its superior flexibility ensures a tight, secure bind every time, even under heavy load.
Recycling & Baling: Ideal for high-pressure baling of cardboard, waste paper, or hay. It offers the perfect balance of toughness and pliability to hold heavy bales together without breaking.
Agriculture & Fencing: Perfect for trellising vines or securing fencing where a reliable, long-lasting hold is required.
Manufacturing & Crafting: A favorite raw material for wire mesh production, custom hangers, and general hardware manufacturing due to its consistent gauge and finish.
Key Features
Enhanced Flexibility: The annealing process softens the wire, making it more pliable and easier to bend, twist, or shape. This feature makes it ideal for use in applications where flexibility is critical.
Versatile: Suitable for a wide variety of applications, including bundling, lashing, fencing, and as a general-purpose wire in a variety of industries including construction, agriculture, and manufacturing.
Durability: While soft and flexible, Black Annealed Wire still has high strength and elasticity, ensuring durability even under moderate tension.
Cost-Effective: Black Annealed Wire is an affordable solution for many applications, offering excellent value for large industrial projects and small DIY tasks.
Corrosion Resistance: While black annealed wire is not as corrosion resistant as galvanized wire, it performs well in dry indoor environments or short-term outdoor applications.
Applications
Bundling and Strapping
Commonly used in agriculture and construction for bundling materials such as rebar, lumber, or pipes. It is also used for bundling plants and vegetables in the garden.
Fencing
Great for temporary fencing, wire mesh applications, or creating cages for animals or other structures.
Crafting and DIY Projects
Popular in crafting projects, from making ornaments to structural frames for DIY creations.
Industrial Uses
Used in manufacturing, construction, and logistics for securing materials, packaging, and general purpose strapping applications.

FAQ
Q1: How do you prevent the wire from rusting during sea transit? A: We apply a high-quality anti-rust oil and use double-layer moisture-proof packaging (plastic film + woven bag) to withstand humid sea conditions.
Q2: Is the wire soft enough for manual tying? A: Yes, our annealing process is specifically optimized for tie-wire applications, ensuring it's easy to twist by hand without breaking.
Q3: Can you provide different coil weights for retail? A: Absolutely. We can produce small coils (e.g., 1lb or 1kg) specifically for hardware retail markets.
To keep the wire in good condition, store it in a dry place when not in use and avoid exposing it to harsh chemicals or prolonged moisture.
