Tate Gallery

The Tate St Ives Project is a refurbishment and extension project set to expand, improve and transform Tate, St Ives.


Application: CARES Approved Reinforcement

Date: June 2015 – 2017

Engineer: Price & Myers

Contractor: BAM Construction

Sub Contractor: Thames Valley Construction



Supplying the reinforcing bar for this project was a challenge as the build requirements included prefabricated cages, galvanising and thermal zinc coating, as well as an impressive 40mm Griptec rebar coupling system specifically designed for applications where neither bar can be rotated; the unique position stud allows rotation when both bars are fixed.

Due to the high temperatures of hot dip galvanising, the 40mm coupled rebar could not be galvanised as it compromised the threads on the couplers so Devoran Metals found the alternative solution of Thermal Zinc Metal Coating which maintained the integrity of the coupler.

The Tate was completed in 2017.
