Metal Treatment

Metal Finishing is a vital manufacturing sector in the UK, enhancing the performance, corrosion resistance, durability, and aesthetics of countless products.

Dominated by small and medium-sized enterprises, this industry thrives on precision and innovation.

ICL stands at the forefront of this field, manufacturing and distributing an extensive array of metal treatment chemicals essential for processes such as electroplating, anodising, etching, and galvanising.
