How the story began

Over the past decades, our work at Astron has been in the pursuit of a single-minded goal: to constantly develop our skills and knowledge within what we now call simplifying construction. The path we chose in order to offer increased customer value has been based on quality, proximity and service using steel as the central theme.

By building a company philosophy based on the values of “neatness and order”, strong entrepreneurship and quick decisions, the conditions were created for the business model which has involved streamlined production, highly advanced distribution, together with a flow of innovations and constant awareness of the needs and wishes of our customers.

Astron's values are based on three key phrases: Simplifying construction, Down to earth and Customer success, which are as true today as throughout the long history.
