85 years of sustainable solutions

Our history

  • 1934

    Alsico’s Beginnings

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

  • 1947

    Gaston Siau, the visionary

    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

  • 1975

    First overseas production

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

  • 1982

    The third generation takes great strides

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

  • 2016

    Alsico Group with its fourth generation on board

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

  • Today

    The focus is on people

    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.

Global reach

nearly 100 years of experience in garment manufacturing

We have a team of around 7,200 employees within 21 factories in 11 countries over 4 continents. We truly are a global company with global reach.

All of our production units, with local management, are owned by the Alsico Group and exclusive to us.

The size of our global manufacturing operation means we can deliver the quickest lead times on the market today. We have full control of our supply chain and resources, therefore we can successfully manage the requirements of multiple contracts and clients across the world.

All of this gives us the capability to respond to your order and your delivery date in a timely fashion. If we don’t have the items you want in stock or if you have requested bespoke products, we have the manpower, the materials, and the infrastructure to deliver.

Our factory in Morocco is the most flexible manufacturing unit in the world and can respond to orders quickly, large or small.

The Alsico Group is the largest purchaser of workwear fabrics in Europe, which not only helps us give you competitive products at competitive prices, it also enables us to source the most technically advanced fabrics available. Sourcing, developing, and bringing innovative workwear solutions to market is at the heart of what we do.
