The range stretches from copper-based products to copper-redused products and a product with noe biocide what so ever.


Fouling on aquaculture nets is an international problem. And increasingly so. Steen-Hansen has been a major player in the anti-fouling business for more that 30 years.  We have now developed something truly new. Through a brand new series of more effective and more environmentally friendly products.
