Wikipedia explains what pickling is:
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, and aluminum alloys. A solution called pickle liquor, which contains strong acids, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.
Many companies and individuals can work in stainless steel.
Many know how to make a stainless steel project look good.
But not many know the secrets of making a stainless steel project look amazing.
And that’s what sets Holland Metal Products apart.
We’re not creators of nice projects. We take your idea and turn it into wow.
And one of the ways we ensure your stainless steel project looks great long after it’s left our factory, is to utilise pickling.
We use a pickling paste on welding seams to ensure that the material does not lose its natural structure. This paste removes annealing colours and welding cinders, which, if left untouched, causes the stainless steel to look terrible.
Bring us your stainless steel concept and we’ll turn it into a reality that’ll not only look great, but give you years of service.
