During this time, the company was transformed from a craft business into a company of steel and metal construction. Groke was among the pioneers of aluminum component manufacturing in the mid 50's. It was around this time that Groke started using aluminum frames for windows and specializing in these innovative products. Aluminum has provided the basis for all products in the Groke company ever since.
