structural reinforcement


STATIbar is a product made of 304 (or 316 according to requirements) class stainless steel DIN X5CrNi 18-10. Thanks to the use of this stainless steel the reinforcing element has many unique properties. Manufacture takes place by cold rolling from round cross-sections During this process the rolled surfaces are extremely hardened while the core remains relatively soft. The subsequent winding adds prestress to the rolled “wings” and the core opposes this thanks to its different structure. The tensile strength is more than doubled by this process. The shape of an anchor with wings provides this system with much better cohesion to the site of application than any other reinforcing material. Tests on the Stati-CAL system took place at the University of Bath. These tests were focused on establishing the values of the reinforcing element under tensile load and shearing load. The whole protocol is fully available on request, the table below shows a summary of these tests. The tests also took place at the TZÚS a.s. (Engineering and Testing Institute for Construction) to verify the properties of the products imported from Great Britain. However one of the properties is not shown in any test, this being that the reinforcing element behaves like a tightly wound spring and so all results are not maximum because they do not reach the elasticity limit of the rod.

STATIbar is supplied in 4.5 – 6 8 – 10 mm cross-sections and in lengths of 1 to 10 metres. Application of this product is versatile and it may be used during new construction work but chiefly during many types of repair and reconstruction work where a special solution is needed.

Nevertheless the main application of the 6 mm cross-section is to use it to reinforce existing masonry structures in combination with STATI-CAL 30 N filler. Supports may be created where a lintel has collapsed above an aperture, or above a sunken area of foundation bed. Its application into existing masonry takes place with minimum damage to the repaired building. So-called stitching together may be used in combination with a 1 m rod across local cracks.

The 8 mm cross-section is used where better connectivity through wider wings is needed. But thanks to the manufacturing process (rolling) less material may be used than in usual round reinforcing elements. For extra heavy applications we also have 10 mm rods, which in combination with the wings, provide a product with extremely high tensile and shearing strength.
  • A wound spring without attaining its elastic limit
  • Super strength on contact
  • Prestress element
  • No catastrophic failure of the rod
  • Lengths of up to 10 m – less overlapping
  • The smallest possible damage during repairs
