BAYDALE Architectural Systems has won a safety and security contract at the Scottish Parliament building.
The company was contracted by Bovis Lendlease to supply bomb-resistant doors.
Baydale has already designed and installed thistle-shaped bomb-proof window frames for the parliament in a deal worth £2.5m.
The latest contract is worth £500,000.
The doors will be made of steel, oak and stone.
Jon Smith, Baydale's managing director, said: "This contract is testament to our success with our previous on-going work to provide the specially designed windows."
