On the BT ThermoPin, Taranto’s Design Manager commented: – “The BT ThermoPin was a simple for choice us. We can use less per SQM than market alternatives, meaning less material and subsequently less overall cost to our programme. The assistance with design for us is imperative, it frees us up to concentrate on other aspects of production whilst giving us assurances that our designs are more than sufficient.

LIV Student Accommodation with over 11 floors of Shearail® used to increase the shear resistance of a slab, and safety transfers the shear load from the slab to the column.

At SDG our knowledge of the impact of the correct acoustics in different environments grows it is no surprise that the education sector is one area where you can’t afford to be complacent.

Through the use of the BT turnbuckle on these LIDL store projects it has been possible to reduce the temporary bracing, increase safety and shorten the assembly time for the precast wall elements , it ticks all our the boxes. We are excited to implement it in our future projects.

SDG have always gone above and beyond for us. With SDG’s technical support our team have the ability to use the most effective and innovative solutions to improve quality, save time and perform more effectively.

I spoke to Ciaran Donnelly and after a few subsequent drawings emailed back and forth we agreed on the detail. SDG had the assembly on site within 3 days and saved us a lot of time on site with cutting and welding. We were able to lower the assembly into place in one piece with no concerns. I would most definitely engage in this service again.
