Steel Expertise Since 1750

The first Weckman products were created in the 1700s as a result of blacksmithing. With steel-forged Weckman expertise, we manufacture the most durable roofs and walls, load-bearing structures and mezzanines, buildings, and tractor trailers.

The smaller carbon footprint of Weckman buildings, sheet metal products, and trailers provides economic benefits

Weckman sheet metal products are utilized in modern roofing profiles, building wall profiles, roof and wall purlins, and trailer side profiles. Sheet metal products are delivered throughout Finland, the Nordic countries, and Europe. The sheet metal products use, among other materials, SSAB GreenCoat® steel, whose bio-based paint coating replaces a significant portion of the fossil oil used in paint coating production with rapeseed oil.
