Comparison: MOSO perforated strip v. ribbed tor steel
The properties of the MOSO perforated strip have been examined by the Institute of Integral Structural Design, Minden: "All our tests showed the breaking load to be at least 3 x the calculated working load.
Tests with the ribbed tor steel did not produce any greater breaking loads than the test samples reinforced with the MOSO perforated strip.
With the test samples reinforced with ribbed tor steel BST 500 S, the first crack appeared at approx. 60% of the overall breaking load, while the lintels reinforced with the MOSO perforated strip the first crack did not appear until failure. This is due to the good "dowelling" of the perforated strip with the mortar (which swells through the holes into the mortar joints on insertion of the strip)." *

Your advantages at a glance:
- Because it encloses the mortar plugs with its dished holes, the MOSO perforated strip reinforcement offers clear advantages in terms of force distribution and transmission. By contrast, the ribs of ribbed tor steels push apart the mortar and have an adverse wedge-shaped action
- The MOSO perforated strip completely fulfils its function and distributes the expansion of the wall shell to many small, still invisible cracks, whereas if the ribbed tor steel is used, large visible cracks already occur at 8.6 kN/m
- This proves that ribbed reinforcement in masonry mortar is considerably less effective at interlocking, and
therefore has a considerably lower load-bearing capacity than the MOSO perforated strip
- Breaking test comparison of MOSO perforated strip and ribbed tor steel: At approximately the same final loading, the first cracks appeared with the ribbed tor steel as from 8.6 kN.
