The rebar mesh welding machine adopts European welding technology, ensuring the flatness of each plate during fast and accurate welding, and the welding speed can be up to max. 100 times/min.
RKM automatic reinforcing mesh welding machine saves labor costs, from automatic mesh dropping, automatic sheet turning process, to fully automatic stacking, modular structure, customers can adjust according to the level of automation.
The production process begins with the automatic feeding of straightened rebar into the welding area. Longitudinal rebar is fed in by a servo-motor-controlled mesh-pulling trolley, while cross wires are automatically dropped at the programmed spacing. Subsequently, Pneumatic electrodes then apply resistance welding to each wire intersection, creating strong and consistent weld joints.
After welding, the finished rebar mesh is conveyed to a stacking system for collection and then output. The entire production process is controlled by a PLC system, ensuring stable, high-precision, and continuous automated production.
Reinforcing mesh is one of the most widely used steel reinforcement materials in modern construction. Manufactured by an automatic reinforcing mesh welding machine, welded reinforcing mesh provides higher installation efficiency, consistent quality, and excellent structural performance. It is extensively used in residential, commercial, industrial, and infrastructure projects worldwide.
The RKM factory successfully delivered a complete reinforcing mesh production line to a customer in Egypt. The client uses round steel bars as raw materials, processes them into three-ribbed bars using cold-rolling ribbed bar equipment, and efficiently produces ribbed steel mesh for the construction industry.
A UK customer, new to the construction mesh industry, customized a 5-12mm pneumatic reinforcing mesh welding machine for producing construction mesh sheets. The customer’s raw material is round steel bars, and the machine is equipped with a 4-12mm straightening and cutting machine.
A UAE customer purchased a 5-12mm rebar welding machine to upgrade their construction mesh production line, resolving issues such as high failure rates, and prolonged downtime with the old equipment. This improved production efficiency and welding accuracy while saving labor costs.
What is a reinforcing mesh welding machine?
A reinforcing mesh welding machine is an industrial resistance welding machine used to automatically weld longitudinal and cross steel wires or reinforcing bars into rigid mesh panels. The finished reinforcing mesh is widely used in concrete floors, roads, precast concrete, industrial slabs and other construction projects. The machine can be configured according to the required wire diameter, mesh opening, panel size and production capacity.
How does a reinforcing mesh welding machine work?
The machine positions the longitudinal wires and feeds the cross wires into the welding area. Multiple welding electrodes then apply pressure and electrical current to weld the wire intersections simultaneously. After each welding cycle, the mesh pulling system advances the panel by the preset cross-wire spacing. Depending on the required automation level, the production line can also include automatic wire feeding, mesh cutting, turning and stacking systems.
How many reinforcing mesh panels can the machine produce per hour?
Because of the raw materials and wire diameter being different, Production speed varies but generally ranges from 60 to 100 welds per minute, about 45panles/H
What wire diameter can the machine weld?
5-12mm
Can the machine weld ribbed rebar?
Yes. The machine can be configured for welding ribbed reinforcing steel as well as suitable round steel wire.
What mesh sizes can one machine produce?
One machine can normally produce multiple reinforcing mesh specifications within its designed adjustment range. Cross-wire spacing can be set through the control system, while longitudinal wire spacing, maximum mesh width and panel length depend on the machine configuration. If you plan to produce several mesh specifications, send us all required wire diameters, mesh openings and panel dimensions before ordering.
Do you have a CE and ISO certificate for the reinforcing mesh welding machine?
Yes, we have.
How do I choose the correct reinforcing mesh welding machine?
The machine should be selected according to your wire or rebar diameter, longitudinal and cross-wire spacing, mesh width, panel length, steel material, required production capacity and automation level. For higher production efficiency, optional systems such as automatic wire feeding, mesh cutting, turning and stacking can be integrated into the production line.
How much does a reinforcing mesh welding machine cost?
The price depends on the wire diameter range, machine working width, number of welding points, welding power, feeding method, production speed and automation configuration. Send us your mesh drawing or specifications for a suitable machine configuration and quotation.
In addition to the provision of a reinforcing mesh welding machine, the RKM factory also offers a wide range of accessories and customization options for your machines.
