Low-carbon Black Annealed Wire

Black annealed wire is a low-carbon steel wire that has undergone annealing treatment and is coated with a black oxide layer. It features a soft surface, uniform color, and excellent flexibility, ductility, and fatigue resistance. This product is widely used in bundling, construction, hardware, handicrafts, gardening, and everyday household applications. We offer various specifications and packaging options, and support customization to meet your diverse needs.

Flexible and Durable: Specially annealed for softness and flexibility, resistant to breakage during bending, and easy to handle.

Rust-Resistant Coating: The black oxide coating on the surface provides basic rust protection, suitable for general dry environments.

High Elongation: High elongation rate allows it to adapt to various shapes for bundling and securing needs.

Complete Range of Specifications: A wide range of wire diameters is available, from thinner gauges (such as 0.7mm, 1.0mm) to thicker gauges (such as 3.0mm, 4.0mm).

Flexible Packaging: Available in coils, spools, or customized packaging according to customer requirements (such as small rolls, cut straight wires, etc.).

Typical Applications:

Construction Binding: Binding rebar, scaffolding pipes, etc.

Agriculture and Horticulture: Securing climbing plants, building fences, floral arrangements.

Household and Daily Use: Binding items, DIY projects, simple repairs.

Crafts Manufacturing: Used as a basic material for weaving and shaping.

Hardware Products: Used as raw materials or semi-finished products in the production of nails, nets, chains, etc.

Processing Services: We provide simple processing services such as straight-bar cutting and small coil rewinding to meet your production line's direct feeding needs.

Packaging Customization: We offer spool packaging suitable for automated unwinding, as well as standard coil and bundled packaging.

4.Optimized Cost and Logistics Solutions

Cost-Effective Advantages: Leveraging centralized procurement and large-scale logistics, we provide you with market-competitive prices.

Flexible Logistics Network: We support various modes, including direct factory shipments and warehouse distribution. Based on your order volume and destination, we can combine the optimal land, sea, or rail transportation solutions to effectively control your overall delivery costs.

Q1: What are the main differences between black annealed wire and galvanized wire? Which one is more suitable for my project?
A: The core difference lies in the surface treatment and corrosion resistance. Black annealed wire has an oxide layer on its surface, providing basic rust protection, suitable for indoor, short-term outdoor, or dry environments, such as reinforcing steel bar tying (which will eventually be covered by concrete) and indoor packaging. Galvanized wire provides stronger corrosion resistance through a zinc layer, suitable for long-term exposure to humid or outdoor environments. The choice depends mainly on the corrosive requirements of the application environment and cost considerations.

Q2: How do I choose the correct wire diameter (gauge)?
A: The wire diameter selection depends on the weight of the objects being bundled, the required bundling strength, and the operating method.

Light bundling (<100kg): Such as cardboard boxes and lightweight profiles, 0.8mm - 1.6mm is recommended.

Medium bundling (100-500kg): Such as rebar bundles and medium-sized pipes, 1.6mm - 2.5mm is recommended.

Heavy-duty fixing/structural applications (>500kg): Such as heavy steel transportation bundling and temporary structural reinforcement, 2.5mm and above is recommended.
Please provide your specific application scenario, and our technical sales team can recommend the best specifications for you.

Q3: What are your packaging options? Can they be adapted to automated equipment?
A: We offer a variety of packaging solutions:

Spool packaging: Designed specifically for automated bundling machines and high-speed unwinding, ensuring no tangling or knotting, for maximum efficiency.

Standard coil packaging: Suitable for manual or semi-automatic operation, with standard weights of 25kg/50kg/100kg.

Custom small coils: Can be packaged according to customer-specified weights (e.g., 5kg, 10kg) for easy distribution and management in the workshop.
Please inform us of your equipment model or operating process, and we will match the most suitable packaging.

Q4: What is the minimum order quantity (MOQ)? Can you provide samples for testing?
A: Our standard product MOQ is usually 1 ton (different specifications can be mixed). For new customers or trial orders, we can provide more flexible starting quantities to support cooperation. We strongly encourage and provide free samples for you to test to ensure the product fully meets your process requirements.

Q5: How long does delivery usually take?
A: For standard specifications and in-stock items, we can arrange shipment within 3-7 business days. For customized specifications or large orders (such as over 50 tons), the production cycle is generally 10-20 business days, and the exact time will be confirmed upon order confirmation. We maintain a safety stock system to effectively meet your urgent needs.
