Timeline

It all started in 1934 when Leopold Aelvoet decided to start his own company for professional workwear.

The small workshop that manufacture the first of the emblematic blue overalls was taken over in 1947 by son-in-law Gaston Siau. He expended the company to a European workwear specialist. Aelvoet and Siau Confection thus became ALSICO

In the mid-1970s, Mr. Gaston Siau was the first to start production overseas.

Thanks to the vision and tireless work of the third generation - Bernard and Philippe Siau - Alsico grew to become a global player. 

In 2016, with Vincent and Gauthier Siau, the fourth generation joined the ranks.  

Today, Alsico Group employs 7500 people and has consolidated sales of more than 250 million euros. With its 100 employees, Alsico nv, as the birthplace of the global group, still plays an important role in the continued development of the company.
