What Balck & Hjelmgrens Plåt och Smide AB does

Balck & Hjelmgrens Plåt och Smide AB is a Swedish specialty construction contractor headquartered in Norrköping, Östergötland, providing sheet metal work (plåt), waterproofing systems (tätskikt), and custom blacksmithing/smithing (smide) for the construction industry. The company was formed in 2013 when Klas Balck and Mattias Larsson merged their separate businesses, and has grown from 5 to approximately 40 employees over roughly eight years. It operates as part of Teqt Group, a national network of roofing and sheet metal specialists that provides access to larger projects across Sweden while preserving local execution autonomy. Notable industry recognition includes the Di Gasell 2019 award from Dagens Industri.

The company's service portfolio centers on three core offerings executed from its Norrköping workshop: sheet metal fabrication and installation (ventilation ducts, roofing, and custom metalwork); waterproofing of low-slope roofs, terraces, parking decks, and pools using bitumen (SBS/APP) or synthetic (PVC/TPO) membranes; and certified structural steel and architectural blacksmithing (stairs, railings, gates, beam transfers). Adjacent offerings include sedum/green roof systems, complete solar cell installations with energy storage and charging stations, roof renovation and maintenance services, and pool waterproofing. Operations are backed by ISO 3834-3 welding quality and EN 1090-1 construction products certifications covering the smithing workshop.

Commercially, the firm operates a project-based B2B contracting model, bidding for tenders and executing construction work for property developers, general contractors, real estate owners, and public-sector construction projects across Sweden. Named customers include NCC Sverige, Sefab Bygg AB, Magnentus Fastigheter, Erlandssons Bygg, Botrygg Bygg, and Miljöbyggarna, with reference projects spanning schools, residential developments, retail centers, and heritage buildings. Distribution relies on direct enterprise field sales and relationship-based tendering, with the Teqt Group affiliation enabling pursuit of larger national contracts. Revenue is not publicly disclosed; headcount growth and Di Gasell recognition indicate a fast-growing regional specialty contractor rather than a national platform.
