Lindab

What Lindab does

Lindab International AB (publ) is a Swedish publicly listed company (Nasdaq Stockholm: LIAB), founded in 1959 and headquartered in Båstad, that develops, manufactures, markets, and distributes products and system solutions in construction steel, organised across two main divisions: Ventilation Systems and Building Products. The Ventilation Systems division supplies a comprehensive portfolio of indoor climate solutions — air distribution, air diffusion, air control, fire protection (Fire System Pro), sound reduction (Acutec-based silencers), demand-controlled ventilation, thermal comfort, marine, and residential ventilation — alongside flagship products such as the Lindab Safe sealed duct system, Plafond XD active chilled beams, and the world's first ventilation ducts in fossil-free steel via the SSAB Hybrit initiative. The Building Products division supplies sheet metal roofs, walls, rainwater systems, doors, and steel profiles, with concentration in the Nordic market.

Lindab monetises primarily through hardware sales of ventilation systems and building envelope products, complemented by software-and-digital-tools revenue from LindQST, CADvent, and TEKNOsim (described as subscription/recurring). Pricing is quote-based for B2B customers, with no publicly disclosed price tiers. The company goes to market via a direct sales force for enterprise accounts, a European-wide distributor and installer/tinsmith network built through more than a decade of bolt-on acquisitions (Felderer AG, Muncholm A/S, HAS-Vent, DiSYS, Firmac, Ventilace Eu, Airmaster, TGA KlimaPartner, etc.), and digital channels including its website catalogue, BIM object library, and the MagiCAD-for-BricsCAD plugin that integrates product selection into architects' and MEP engineers' BIM workflows. Reference customers span real estate (Castellum, AMF Fastigheter), construction, hospitality (Umbria Resort), port operations (Pireus), cultural (Arvo Pärt Centre), and education (University of Ostrava). Recent financial signals include Q4 2025 sales of SEK 3,134 million with a 6.5% adjusted operating margin, full-year 2025 revenue around SEK 14 billion, and a December 2025 divestment of the Hungarian profile operations as part of Eastern European portfolio restructuring.
