Quick and Safe
This must-have product performs highly efficient in controlling slab bursting during stressing operation. Its performance has been proven for years by leading post-tensioned slab constructors. Nothing is quicker and safer than this!
Laboratory Tests and Simulation
FINITE ELEMENT ANALYSIS OF LOCAL ZONE
As part of our development program, numerous refined FE models of slab local zone are analyzed for verifying stress intensities in most components.
LOAD TRANSFER TESTING
We have conducted testings for various types of anti-burst rebars. One is a control specimen without anti-burst rebar(left), a specimen with HELIX (middle) and a specimen with conventional ties (right). The performance of HELIX is superior in ultimate load and in maintaining compressive strain after peak load.
