Technology

Patented weld-free technology.

Spinmaster is the only machine in the world that produces rebar roll mats without heat or welding, using mechanical twisting of the bars.

This patented system creates strong and flexible joints within the mat. By unrolling two mats on site in orthogonal directions, a fully interlaced reinforcement mesh is formed — ideal for dynamic conditions and as an alternative to welded mesh.

SteelMaster machinery does not require royalty payments.

System benefits

Advantages of the Spinmaster System.

01

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.

02

Safety

Less manual lifting and fewer repetitive tasks improve health and working conditions.

03

Reduced Manpower

Streamlined installation minimizes the need for cranes, manual handling and labor.

04

Material Savings

Precise pre-fabrication and customized shapes reduce overlaps and save material.

05

Consistent Quality

Every roll mat is manufactured with high precision – consistently and to specifications.

06

Easy Wall Application

The flexible wire system enables use as wall reinforcement without the risk of breakage.

07

Approved For Earthquake Zones

Ideal for seismic regions where welded connections are restricted or prohibited.

08

Compatible with all materials

Applicable to all types of rebar – including epoxy-coated, stainless steel, or fibre-reinforced materials.

09

Flexible bar adjustment

Bars remain partially movable after unrolling, allowing for on-site fine-tuning if needed.
