any companies offer aluminum gate and fence products. Why don’t we? TEK Gates and Fences has been working with steel for the past 12 years and we continue to be impressed by its strength and longevity. While aluminum has become popular for gates and fences due to its corrosion resistance and weight, steel is a stronger alternative. With a Hot Dipped Galvanized undercoat and a baked on Powder Coat finish, a steel gate or fence will maintain it structural integrity and outlast an aluminum gate or fence.
