Proper name If this is the client website https://www.becn.com/products/roofing/metal-roofing/C-578033... then it appears to be the proper name of the product. The word "cap" means that this is a product used to create the top/outer surface of the roof. On the other hand, a hip or ridge cap would be specifically used on the external angle of the hip or ridge. I suggest that you ask the client whether or not they want these product names translated.
