UPN (or UNP) and UPE are standardized stainless steel channels used in various industrial applications, including construction and machinery. UPN channels are known for their flexibility in design and efficient construction, allowing for cost-effective prefabrication. These channels are primarily made from recyclable scrap stainless steel. UPE channels are similar but have parallel flanges and are slightly thinner with wider flanges compared to UPN channels.
