If you have never been tasked with choosing stainless steel storage cabinets for a cleanroom, make no mistake; you have an important job ahead of you. There is a lot to consider, for example choosing the right classes and gauges of steel. Other things to consider could include the right kind of door, cabinet top, or whether or not paint is a good idea for the environment.
The following tips will help you when buying storage cabinets for a cleanroom for the first (or hundredth!) time.
Classes of Stainless Steel
The different classes of stainless steel make a huge difference in the cleanroom environment. Stainless Steel 304 is the basic alloy that is nonmagnetic and holds it’s strengthened by being cold formed. This works great in a cleanroom because the corrosion rate is so small that there are less contaminants and particulates released in the cleanroom. You also might consider 316 steel, with a higher level of corrosion meant to withstand industrial chemicals. Overall, the 300 series stainless steel has close to 15-18% chromium, a hard but brittle metal, and is superior in the corrosion resistance to the 400 series.
Stainless Steel Gauges
The gauge of the stainless steel cabinet is a measurement of the metal’s thickness. When choosing a stainless steel cabinet, you should opt for a lower gauge, which indicates that the steel is thicker. A thicker metal is less susceptible to vibrations which helps prevent the release of particulates into the cleanroom and is less susceptible to denting.
Potential Cleanroom Contaminants
If you look into purchasing stainless steel painted cabinets, you should always take potential contaminants into consideration. For example, a painted cabinet could chip, and contaminate the cleanroom or lab. Contamination may lead to lost production time which can be very expensive in terms of both time and money.
Take Cabinet Tops into Consideration
One feature of a stainless steel cabinet that many people fail to consider is its’ top. For example, if the cabinet will be primarily used for lab applications, a flat top will suffice. However, a stainless steel storage cabinet with a slope top option is a better option for a cleanroom application because the cabinet can be easily cleaned and won’t allow particulates to accumulate on the top.
Storage Cabinet Doors
There are several door options for stainless steel storage cabinets; two of the most popular being solid stainless steel and glass stainless steel supply cabinets. If you do choose a glass door you should be aware that it makes it a lot harder to ship. In the shipping process your door could crack or spider depending on the type of class. You never know what shipping and freight companies might run into during shipping.
Stainless steel storage cabinets are certainly worth the investment but it’s important to choose your cabinet carefully and make sure it’s the right type for your cleanroom or lab. Contact Clean Room World today for advice on which stainless steel storage cabinet is right for your needs.
