KA construct

What KA construct does

KA construct is a Belgian specialist contractor in custom aluminium building envelope solutions, headquartered in Beerse in the Kempen region of Flanders. The company designs, supplies, and installs aluminium windows and doors, curtain walls (vliesgevels and gordijngevels), fire-resistant joinery, balustrades, sun shading, and facade finishing for medium-to-large construction projects. Its core technology centers on custom aluminium profile design executed in synergy with sister company Sprangers Aluminium, enabling project-specific profile solutions developed from concept through fabrication and on-site installation.

The company serves contractors, building promoters, property developers, and architects across Belgium, with named projects spanning hospitals, schools, residential complexes, sports facilities, and commercial real estate. Its go-to-market is direct enterprise field sales: KA construct engages proactively with architects and main contractors from the design phase and positions itself as a total outsourcing (ontzorging) partner covering the full building envelope with the exception of the roof. Pricing is custom and quote-based per project; no public pricing exists.

KA construct operates as part of the Sprangers Groep conglomerate alongside sister company Sprangers Aluminium, and is managed by Rita Sprangers as Algemeen directeur. The firm holds the FAC Keurmerk (Federatie Aluminium Constructeurs), VOKA Duurzaam Ondernemen, and Duurzaam Schrijnwerk certifications, and markets 100% recyclable aluminium with a sustainability positioning. Revenue is not publicly disclosed, the firm is private and family-controlled, and there is no external funding history; the company completes roughly 30 projects per year with a team of approximately 36-50 employees and more than 100 lifetime customers.
