The new approval for the MTH anchor introduces improvements in mechanical resistance and expands the installation possibilities to a greater number of applications. The update to its European Technical Assessment (ETA) includes significant advances in both shear and tensile behaviour and in the extension of the available range.
These improvements reinforce the safety of the anchor in structural applications in non-cracked concrete, consolidating it as a reliable solution for demanding projects.
Better shear behaviour
The update to the MTH ETA validates a significant improvement in the anchor’s performance, thanks to the improved strength of the carbon steel used in the MTH and MTH-AT versions.
The improvement in the material translates into a significant increase in shear resistance, with increases that reach values well above the previous ETA. Overall, shear resistance shows an average improvement of approximately +35%, providing more reliable performance in applications with lateral loads.
Greater tensile strength, especially in M6 and M8
The new ETA also guarantees an increase in the tensile strength of the anchor, with a particularly marked improvement in the M6 and M8 metrics, which show more robust behaviour against extraction forces.
These improvements add extra safety in applications where traction is critical.
New sizes available across the range
In addition to the improvements validated in the ETA, the MTH expands its possibilities with new options to adapt to more installation scenarios:
- New lengths in the MTH range for applications requiring greater anchorage depth.
- Expansion of sizes in the MTH-A4 range (stainless steel), particularly suitable for corrosive environments or high-durability installations.
With this expansion, the MTH range offers greater versatility and a wider range of solutions for installers and specifiers.
ETA approval: technical safety with European backing
The European Technical Assessment (ETA) certifies that the MTH meets the safety, performance and reliability requirements defined at European level, especially for products without a harmonised standard.
This new approval not only improves the performance of the anchor but also guarantees its suitability for structural applications in non-cracked concrete, providing peace of mind for technicians, site managers and installers.
The new improvements have already been implemented across the entire range and incorporated into the product’s technical documentation, which is available for consultation or download.
