A Partner Serving Designers and Builders
We provide technical advice and support to all builders, along with design 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 for professional construction.



The Union of Sheet Metal Tradition and Modern Technology
Weckman represents steel-strong Finnish expertise that 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 know 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 time, nature has represented something mystical and unpredictable to people, something wild and difficult to control. Something you simply have to live with and manage when the sun scorches, the frost bites, storms rage, rain lashes, and snow swirls. At Weckman, we see 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 market’s most comprehensive range of metal roofing. There are over 200 options to choose from for all roofing needs. The roof’s durability, ease of maintenance, quality, and finished appearance are matters of honor for 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 color and coating range offers a favorite for every taste. Roofing 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 water roofs or 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 Striking and Durable Façade Cladding
Weckman steel profiled sheets create striking and durable façade cladding. The sheets are typically used in warehouse, industrial, and production buildings where expressive, maintenance-free, and cost-effective wall surfaces are needed quickly.


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


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

Weckman Steel Oy Vierumäki
The Weckman family’s steel expertise originated as far back 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 Counsellor Pekka Weckman and Matti Weckman, founded Weckmanin Konepaja Oy in 1962 in Vierumäki, in the village of Härkälä. In 1997, as the business expanded internationally, the company name was changed to Weckman Steel Oy. At our factory midway between Lahti and Heinola, with excellent transport connections, we manufacture all steel roofing sheets and related roofing materials. In Vierumäki, we also produce 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 dedicated to steel product manufacturing. The factory’s own transport department comprises 9 trucks with drivers.

Weckman Steel Oy’s Iisalmi factory began operations in 1984. The approximately 5,000 m² production facility in Iisalmi focuses on producing the most popular basic profiles and distributing products to Northern Finland.
