Alexander Gordon and Co
Presumably established by Alexander Gordon
c.1840 George Henry Phipps (1807-1888) became manager of the factory of Alexander, Gordon and Co, who executed a large amount of ironwork for lighthouses and beacons for the Trinity Corporation, of Deptford-le-Strond. Notable among these works were the cast-iron columns and wrought iron bracing of the Maplin Sands lighthouse, on the estuary of the Thames. This lighthouse was remarkable as constituting the first successful application of Mitchell’s screw-piles to submarine foundations. The firm also executed, during Mr. Phipps’ managership, the cast-iron work for the celebrated Wolf Rock beacon, which preceded the existing granite lighthouse.
The 1839 cast iron girders for a bridge designed by I. K. Brunel to cross the Grand Union Canal at Paddington show the maker's name, 'Gordons & Co Deptford'[1]. Same company?
After a few years the Deptford foundry was closed.
