Architectural and Metal Systems (AMS) is to create 31 new jobs in Co Cork as part of a €8 million expansion.
The firm is to open a new aluminium extrusion plant in Little Island. The plant is the first of its kind in Ireland.
The new investment is in addition to a previous €4 million spend on a state-of-the-art powder paint-coating line in the firm. The investment is being supported by the Government through Enterprise Ireland.
Aluminium extrusion is a process which produces lengths of precision aluminium profiles which are the essential raw material for aluminium window and door-makers, engineers and sign manufacturers.
The company, which was established in Cork 20 years ago, employs 66 workers making aluminium products such as curtain walling, window and door systems and related components.
Recruitment for the new positions is already underway.
"This investment is the culmination of a long-held ambition of the directors to have all the processes from extrusion to powder-coating and fabrication on the one site," said AMS managing director Chris Martin. "This gives AMS a unique level of flexibility which is unrivalled in Ireland and very rare in Europe or the UK."
