Linetec Continuing Education Program – "Introduction to Coatings: Field Performance and the Application Process"
by Tammy Schroeder, Linetec’s marketing specialist
Building materials and surfaces are put through some of the most rigorous, day-to-day durability challenges. It helps to know which finishes will be the best choice for maintaining the longest lifespan possible. This certainly applies to exterior architectural aluminum. The finishing technologies and processes involved in this area of design and construction are extremely important. In the architectural industry, the two types of factory-applied finishes for aluminum are anodize and paint. Both processes can deliver a long-lasting finish on building products. The finish choice of a particular project is based on a combination of personal taste and performance criteria.
