Turnkey BRC Construction Mesh Production Line in Brazil: Integrated Wire Drawing, Cut-to-Length Straightening & Automatic Mesh Welding Solution
Surging Infrastructure Demand & Raw Material Processing Challenges in Brazil
Brazil’s construction and infrastructure sectors are experiencing strong growth. From industrial concrete flooring and high-rise foundations to precast panels and civil projects, high-strength BRC reinforcing steel mesh is in massive demand across South America. However, local steel mesh producers often face squeezed profit margins when purchasing pre-drawn wire or pre-cut wire rods from external suppliers.
A leading building materials supplier in Brazil sought to establish a fully integrated, highly automated mesh manufacturing facility. Their goal was to process locally available 6.1mm smooth low-carbon steel wire rod coils down to 3.6mm finished wire, align and cut cross wires efficiently, and continuously weld standard construction mesh panels with minimal manual intervention.
To achieve maximum profit margins and operational flexibility, the client required a comprehensive engineering solution that solved three core challenges:
- In-House Raw Material Processing: Direct high-speed wire drawing from 6.1mm rod to 3.6mm round wire without intermediate annealing.
- Automated Cross-Wire Feeding: Fast, straight, and precise cut-to-length cross wire preparation for continuous hopper loading.
- High-Speed Mesh Welding: Automatic longitudinal coil feeding paired with precise mesh welding to guarantee flat, high-strength reinforcing sheets.
JIAKE’s Integrated Turnkey Solution: From 6.1mm Rod to Finished Welded Mesh
To fulfill all technical and capacity requirements, JIAKE Machinery engineers designed a seamless, 3-stage integrated production system tailored specifically to the client’s plant layout and production targets in Brazil.
| Production Stage | JIAKE Specialized Equipment | Process Function & Performance Highlights |
|---|---|---|
| Stage 1: Wire Drawing | Straight-Line Wire Drawing Machine | Reduces 6.1mm low-carbon steel wire rod coil down to 3.6mm smooth round wire with high speed, internal cooling, and high tensile strength. |
| Stage 2: Wire Straightening & Cutting | GT3-8 High-Speed Wire Straightening & Cutting Machine | Straightens 3.6mm coiled wire and cuts it into precise lengths for cross wires (weft wires), which are automatically dropped into the welder hopper. |
| Stage 3: Mesh Welding | 3-6mm Automatic Reinforcing Mesh Welding Machine | Feeds line wires directly from coils (line wire payoff stands) while feeding pre-cut cross wires from a multi-blanking hopper for high-speed automatic resistance welding. |
Key Equipment Highlights & Technical Breakdown
1. Heavy-Duty Straight-Line Wire Drawing Machine (6.1mm to 3.6mm)
The line begins with JIAKE’s high-efficiency straight-line wire drawing machine. Raw 6.1mm wire rod coils pass through tungsten carbide drawing dies, reducing the diameter to 3.6mm in a continuous, non-slip process. Advanced narrow-slot water cooling and pneumatic dust extraction ensure smooth wire surface finish, uniform diameter tolerance (±0.02mm), and prolonged die lifespan.
2. GT3-8 High-Speed Wire Straightening & Cutting Machine
Part of the drawn 3.6mm wire is loaded into the JIAKE GT3-8 wire straightening and cutting machine. Utilizing a high-speed rotating straightening rotor and alloy cutting blades, the GT3-8 delivers perfectly straight 3.6mm wires cut to exact mesh widths (e.g., 2.4m). These straight cross wires are stored directly into the feeding hopper of the mesh welding machine, eliminating surface scratching and bending.
3. 3-6mm Automatic BRC Reinforcing Mesh Welding Machine
The main component of the line features JIAKE’s state-of-the-art 3-6mm reinforcing mesh welding machine:
- Direct Line-Wire Coil Feeding: Line wires (longitudinal wires) feed automatically from coil payoff stands through flattening devices, eliminating pre-cutting steps and saving labor.
- Automated Hopper Cross-Wire Blanking: Pre-cut 3.6mm cross wires are dropped one by one from the step-motor controlled hopper into the welding electrodes with exact timing.
- Water-Cooled Solid Transformer System: Heavy-duty water-cooled welding transformers ensure robust, uniform weld spots across all mesh intersections.
- CNC Servo Mesh Pulling: A Panasonic servo motor and pneumatic gripper rack pull the welded mesh sheet automatically, allowing flexible mesh grid spacing (e.g., 100x100mm, 150x150mm, 200x200mm).
