A Partner Serving Designers and Builders
We provide technical advice and support to all builders, as well as design and dimensioning software for construction professionals. Weckman’s expertise is world-class—the best results are achieved when Weckman is involved in the project planning from the very beginning. Our extensive product range also includes self-supporting profiled sheets, composite panels, and steel purlins designed for professional construction.



The Union of Sheet Metal Tradition and Modern Technology
Weckman represents steel-strong Finnish expertise, which creates the most durable roofs and walls, halls, load-bearing structures, and intermediate floors for people’s safe living. Weckman’s expertise combines old sheet metal traditions with modern production technology. Over the decades, Weckman products have been delivered to almost every corner of the world. In addition to Scandinavian conditions, we are familiar with the steppes of Siberia, the deserts and mountains of Tajikistan, the stormy winters of Central Europe, and the permafrost and hot summers of Canada. Weckman Steel is a Finnish family business, and our expertise as professionals in steel roofing and wall cladding products has been passed down from father to son for eight generations. We are the largest fully Finnish-owned expert company in roofing sheets and products.

Roofs for the Challenges of Harsh Conditions
Throughout the ages, nature has represented something mystical and unpredictable to people, something wild and difficult to control. Something you simply have to live with and cope with when the sun scorches, the frost bites, the storms rage, the rains lash, and the snow swirls. At Weckman, we view nature’s varying conditions as challenges. Through determined work, we have developed products that enable us to meet these challenges.
Over 200 Roofing Options
Weckman offers the most comprehensive range of metal roofing on the market. There are over 200 options to choose from for all roofing construction. The durability, ease of maintenance, quality, and finished appearance of the roof are matters of honor to us, which you can rely on in any weather. Available options include tile-profile sheets, standing seam roofing, mechanically seamed roof panels, straight-profile corrugated sheets, and self-supporting profiled sheets. The extensive range of colors and coatings offers a favorite for every taste. Roofing is available with 30-, 40-, and even 50-year



Load-Bearing Structures and Intermediate Floors
Self-supporting Weckman profiled sheets are safe, CE-marked, and subject to continuous quality control (VTT). They are used as waterproof roofs or as load-bearing structures in upper and intermediate floors and walls, for example in halls, commercial spaces, and industrial buildings. Thanks to their high load-bearing capacity, the sheets are even suitable as concrete casting molds.


For Impressive and Durable Facade Cladding
Weckman steel profiled sheets create impressive and durable facade cladding. The sheets are typically used in warehouse, industrial, and production buildings where expressive, maintenance-free, and cost-effective wall surfaces are desired quickly.


Customized Halls Delivered Ready-Made
We manufacture custom-dimensioned steel-framed prefabricated halls for versatile applications. The basic range includes gable-roofed cold halls, thermally insulated halls, mono-pitch roofed halls, and livestock barns. Thanks to their adaptability, the halls can be modified according to usage needs, for example with sliding doors or high and wide door openings.


Tractor Trailers for Versatile Production Work
Our work, which began over 250 years ago, to manufacture products and tools for Finland’s harsh natural conditions continues today with the production of Weckman tractor trailers. Our steel-hard expertise ensures that trailers developed for versatile agricultural and forestry transport needs and versatile production work withstand all conditions—from generation to generation.

Weckman Steel Oy Vierumäki
The Weckman family’s steel expertise originated as early as 1750, when the first steel blacksmith products were forged in the Weckman workshop. Agricultural trailer production began in the 1950s. Industrial mass production gained momentum when the Weckman brothers, Industrial Counselor Pekka Weckman and Matti Weckman, founded Weckmanin Konepaja Oy in 1962 in Vierumäki, in the village of Härkälä. In 1997, as operations became strongly internationalized, the company name was changed to Weckman Steel Oy. At our factory halfway between Lahti and Heinola, along good transport connections, we manufacture all steel roofing sheets and related roofing accessories. In Vierumäki, we also manufacture steel sheets for wall cladding, load-bearing steel structures for professional construction, as well as halls and tractor trailers. Approximately 30,000 m² of heated production space is used for steel product manufacturing. The factory’s own transport department comprises 9 trucks with drivers.


Weckman Steel Oy Iisalmi
Weckman Steel Oy’s Iisalmi factory began operations in 1984. The approximately 5,000 m² production facilities in Iisalmi focus on the production of the most purchased basic profiles and product distribution to Northern Finland.
