As the best way to meet the growing demand, Wilhelm & Mayer splits off the falsework side of its business to form LGB Lehrgerüstbau GmbH. The two founders of the firm, Dipl.-Ing. Werner Wilhelm and Dipl.-Ing. Herbert Keckeis, become managing directors.


LGB and Eduard van Randen AG merge. The Swiss subsidiary VAN RANDEN – LGB AG – Schweiz is created. Operations in both countries benefit from the synergies generated by even closer cooperation and joint material management within the enlarged company.
