ENEN
Sign Factory in Linköping since 1916

Signs built
in operation for decades.

Signs, front panels, and labeling for industrial and defense applications. We mill, anodize, engrave, bend, weld, and print in-house, so your part doesn’t leave our facility until it’s finished.

Services

From raw sheet metal to a ready-to-install sign.

Most jobs go through several of these stages. A front panel can be milled, finished, engraved, and printed without ever leaving the workshop—shorter lead times and a single point of contact throughout the entire process.

Anodizing bath in SMF's workshop
Surface Treatment

Half of everything goes through the long bath.

Few workshops in Sweden can anodize long pieces in a single piece. A long panel gets a uniform, durable surface from edge to edge, without seams and without having to be sent between suppliers.

That's also why other manufacturers send their parts to us.

Get in touch, and we'll work out the details.

A drawing, sketch, or description works just as well. Please specify the quantity, material, and where the sign will be placed—this will ensure a faster and more accurate response.
