Aston Martin contracts worth over £60 million will be on offer to Welsh businesses.
First Minister Carwyn Jones announced these contracts would be advertised on the Welsh Government's procurement portal, Sell2Wales.
It is the first time that private sector contracts have been advertised on the portal designed to help Welsh businesses win contracts.
This announcement comes as Aston Martin gains official access to the three Ministry of Defence 'super hangars' in St Athan, which will be used to manufacture the new DBX model from 2020.
Ammanford-based construction firm, TRJ has been unveiled as the first Welsh business to benefit after securing the contract for phase 1 of Aston Martin’s initial work at St Athan.
The St Athan site is expected to employ 750 workers before 2020 and it is estimated the move will bring economic benefits worth half a billion pounds to Wales.
