Case Study: Turnkey Wire Drawing & Construction Mesh Welding Line Operating in Zimbabwe
Project Overview
- Client Location: Harare, Zimbabwe
- Industry Segment: Construction Materials & Welded Rebar Mesh Manufacturing
- Raw Material: Φ 4.8 mm Plain Carbon Steel Wire Rod
- Finished Product: 200 × 200 mm Mesh Grid (4.2 mm 3-Ribbed Deformed Rebar)
- Equipment Delivered:
- Key Result: Established an end-to-end processing facility from plain rod to 3-ribbed rebar mesh, achieving a daily output of 18+ Tons with reduced raw material acquisition costs.
Client Background & Industrial Challenge
In Zimbabwe’s rapidly growing infrastructure sector, demand for 3-ribbed deformed steel mesh for concrete slab reinforcement has surged. However, procuring pre-ribbed rebar wire directly from overseas or local steel mills incurs high material costs and erratic delivery schedules.
A leading structural supply company in Harare sought a complete turnkey manufacturing solution from RKM Machinery to process affordable plain round wire rod into high-strength ribbed mesh locally.
Straight Line Wire Drawing Machine in Zimbabwe
Technical Workflow & Custom Engineering Solution
To meet the client’s strict specification requirements, RKM engineers designed a continuous 3-stage automated processing line:
Stage 1: Continuous Wire Drawing & 3-Rib Rolling
- Raw Material Feed: Φ 4.8 mm plain round wire rod.
- Drawing Technology: RKM 4-Block Straight Line Wire Drawing Machine. Utilizing tuning-arm capstan control and heavy-duty tungsten carbide dies, the machine draws the Φ 4.8 mm rod down to Φ 4.2 mm.
- Rib Rolling Cassette: A cold rolling die box forms uniform 3-rib deformed grooves on the wire surface, significantly enhancing concrete bonding strength in accordance with African structural standards.
Stage 2: High-Speed Weft Wire Preparation
- Machine Used: RKM GT3-8 High-Speed Wire Straightening & Cutting Machine.
- Function: The drawn Φ 4.2 mm 3-ribbed wire is automatically straightened and cut to exact pre-determined lengths to serve as weft wires (cross wires) for the welding system.
Stage 3: Automatic Mesh Welding System
- Machine Used: RKM Heavy Duty Reinforcing Mesh Welding Machine.
- Line Wire (Longitudinal) Feeding: Coil-fed (continuous wire payload) through precision tensioners to minimize stopping times.
- Weft Wire (Cross Wire) Feeding: Pre-cut 4.2 mm 3-ribbed wires fed automatically from a multi-slot hopper via magnetic discharge arms.
- Mesh Specification Produced: 200 × 200 mm grid opening with continuous pneumatically controlled spot-welding transformers.

Customer Benefits & On-Site Operational Impact
- Significant Raw Material Cost Reduction: By purchasing Φ 4.8 mm standard wire rod and drawing/ribbing it in-house, the client cut raw material purchasing overhead by over 18%.
- Seamless Line Integration: The combination of coil-fed line wires and pre-cut weft wires enabled non-stop welding cycles, yielding over 1800 square meters of mesh per 8-hour shift.
- High Strength & Precision: The Panasonic PLC system ensures 200 × 200 mm grid accuracy with zero manual measurement required.
“Partnering with RKM Machinery gave us a huge competitive edge in Zimbabwe. The 4-block straight line wire drawing machine operates smoothly even under unstable factory power conditions, and the mesh welder delivers incredibly clean, strong welds.”
