After 1993 the company became actively engaged in the  production of aluminium joinery, complementing its construction and refurbishment work. The company was engaged in the production of aluminium joinery, suspended  facades and Etalbond curtain walling until 2000.

Since then Blitz has also developed its own PVC joinery production unit equipped with a hydrolically-powered production line made by Elumatec, with a monthly production capacity of 1000 sq.m. In 2005 Blitz-Sokolov LTD also acquired ISO 9001:2000 certification for Quality Management Systems, which guarantees the highest production standards.
