What Constructech does

Constructech AB is a privately held Swedish technical services firm headquartered in Strängnäs, Sweden, providing accredited testing, training, and consulting services to the construction and automotive industries. The company's core laboratory offerings include wind load testing of roof constructions per ETAG-006 and EN:16002-2010, structural load testing, and accelerated corrosion testing using a Kesternich chamber per ISO 6988 and DIN 50018. Constructech also delivers project management services applying Six Sigma methodology and a training portfolio that includes approved Hot Work (Heta Arbeten) certification and roof installer training materials developed in collaboration with industry bodies TIB, BYN, and Hermods for both vocational education and practicing roofers.

Constructech also markets RoofCalculator, a proprietary wind load calculation software compliant with EN-1991-1-4 and featuring national adaptations for 28 countries, distributed via dedicated roofcalculator.se and roofcalculator.eu domains. The commercial model is sales-led B2B and combines three revenue streams: professional services from laboratory testing, professional services from training and certification, and one-time software licensing for RoofCalculator. The company holds accreditations from three European certification bodies — Sintef Building & Infrastructure (Norway), Intron Certificatie BV (Netherlands), and SP Sitac (Sweden) — which function as the primary credibility and barrier-to-entry asset for its wind load testing business. Pricing is not publicly disclosed; customer engagement is contact-based.

Constructech operates from a single Swedish site with no disclosed subsidiaries, parent company, or external investors, and no disclosed funding rounds. There are no disclosed customer logos, no disclosed revenue, and no disclosed headcount. The company's operating geography is Europe (with software reach across 28 countries), while the laboratory physically serves customers regionally from Strängnäs. The company appears to be an independent specialist operating in a niche between regulatory testing bodies and construction/automotive industry customers.
