Stainless steel is a better choice than polycarbonate for demanding environments because it does not crack or degrade when exposed to UV, chemicals, or impact. Cracking can compromise an enclosure’s protection and allow water or other contaminants to enter. Stainless steel provides a more durable solution for applications where long-term protection from environmental and physical exposure is critical.

The best material depends on the application. Stainless steel can be the better choice for demanding environments where impact resistance, corrosion resistance, temperature tolerance, and long-term durability are priorities. Polycarbonate can be appropriate for applications where lower weight and cost are more important and the enclosure will not be exposed to the same level of physical or environmental stress.
