Spinmaster - reinventing reinforcement.
The revolutionary system for producing non-welded rebar roll mats
A patented non-welding technology
The patented SpinMaster system is the world’s only machine that creates reinforcement roll mats by mechanically twisting the wires – withour heat, without welding.
This patented method creates strong, flexible bar connections within the roll mat.
When two roll mats are unrolled on site at 90 degrees to each other, a fully interlaced mesh structure is formed – ideal for dynamic load conditions and a revolutionary alternative to welded mesh.

Advantages of the SpinMaster System
Speed
Significantly faster installation on site thanks to pre-fabricated roll mats in custom sizes. Up to 80 % time savings compared to laying welded mesh or loose rebar.
Safety
Less manual lifting and fewer repetitive tasks improve health and working conditions.
Reduced Manpower
Streamlined installation minimizes the need for cranes, manual handling and labor.
Material Savings
Precise pre-fabrication and customized shapes reduce overlaps and save material.
Consistent Quality
Every roll mat is manufactured with high precision - consistently and to specifications.
Easy Wall Application
The flexible wire system enables use as wall reinforcement without the risk of breakage.
Approved For Earthquake Zones
Ideal for seismic regions where welded connections are restricted or prohibited.
Compatible with all materials
Applicable to all types of rebar - including epoxy-coated, stainless steel, or fibre-reinforced materials.
Flexible bar adjustment
Bars remain partially movable after unrolling, allowing for on-site fine-tuning if needed.
Machine capabilities:
Spinmaster Classic:
Drawing the material from the right hand-side.
Spinmaster Backfeed:
As the name suggests: The machines is fed with rebars from the back, reducing the layout of the machine to a minimum.
The Backfeed variant can produce 1-3 rollmats at the same time, depending on bar length.
Optional add-ons:
Bar feeding from movable bar storage:
Automize your SpinMaster even more! With the movable bar storage, handling of raw materials are reduced to a minimum.
