Why is a correct surface treatment so important for your cleanroom crane?

Surface treatment: the material and coating of your cranes. Do you need stainless steel or painted steel? If you choose the former, many different treatments are possible. From blasting to polishing to powder coating. Choosing the right treatment can have so many benefits. Curious as to what these are? Then read on.


To keep it short and sweet: the right surface treatment will make your lifting and hoisting equipment easier to clean. It will therefore prolong the life of your equipment. Your crane will be a beneficial investment, not just an expense.


Stainless steel or painted steel

Depending on the industry you work in, you are better off with stainless steel or painted steel. They both have their advantages and disadvantages. And both have different surface treatments available, each with their own benefits. For example: if you blast stainless steel with grit, you essentially ‘damage’ the surface. This treatment is used to round off peaks in the material, making it smoother and easier to clean.


What surface treatment do I need?

Good question. The answer depends on your specific needs, but there are certain elements that influence your choice. Does your company process acids or salts? Because these have a different effect on the surface of your equipment than, say, powder. Does the crane need to be UV resistant? And what is the environment of your cleanroom? If it is very humid, you might want to consider using a stainless-steel solution.


Risks of a wrong coating

Generally speaking, coatings are better for the dry industry. Because if you use synthetics without surface treatment, they can absorb moisture and create a perfect attachment spot for bacteria. Which is out of the question for a cleanroom. Additionally, a coating also protects steel against acids and oxygenates, and prevents oxidation. Oxidation will affect the surface of your lifting and hoisting equipment.


A general rule of thumb

A correct surface treatment realizes a smooth and closed surface. Meaning: without holes or cracks. Because micro bacteria can grow in the smallest open spaces, and you do not want that. Correct treatment is also easily washable. It should be cleaned until the desired grade, for example with a damp cloth or chemicals. And last but not least: your crane should be perfectly suited for your cleanroom.
