Anti-corrosion treatment with organic-mineral sealing
In SUMAL we work for the constant improvement in our manufacturing processes to be able to offer top quality and durable products.
Within this continuous improvement, and through a new product formulation in our anti-corrosion treatment, we have managed to further improve the durability of our containers and roll containers.
The electro-zinc and the inmersion of each peace in a passivated bath, allows to protect not only the exterior but also the interior of the materials (essential protection).
