The story of Weckman

The story of Weckman begins in the mid-18th century, when blacksmiths created the first Weckman products.

The smaller carbon footprint of Weckman steel halls, sheet metals, and trailers brings economic benefits

Production innovations of Weckman steel halls will reduce the carbon footprint from production to commissioning. The amount of steel in production will be reduced by up to 25%, which will also reduce the environmental impact of transporting and erecting halls. CO2 emissions will be reduced by around one million kilograms a year as a result of reduced steel use alone.
