Metal is a desirable building material because it is durable but simultaneously attractive. Unfortunately the properties of some metals can naturally lead to rusting, oxidizing, and discoloring either over time or when exposed to moisture, UV rays, etc.

What composite materials do is take the best properties of many different types of metals and combine them into a single unit. Composite metals are desirable in the building trades because they last longer and show less visible signs of age – thus retaining value usually over the entire life span of the property.
