Galvanized Steel GuttersGalvanized gutters are steel gutters coated with a layer of zinc. This type of gutter is strong but is also prone to rust. Proper gutter installation is very important to ensure proper drainage and avoid standing water in your gutters. Leaf protectors will reduce the amount of leaves that will settle in your gutters. It is strongly recommend that you inspect and clean galvanized gutters often to prevent clogging and premature rusting. GalvalumeGalvalume is steel‚ with a coating

that can be observed in this zone: they are the Widmanstatten patterns and columnar grains. These patterns are observed to have random directions. The Widmanstatten patterns appear due to large austentite (gamma-Fe) grains being cooled rapidly‚ as steel is a good conductor of heat. The rapid cooling also resulted in the columnar grains. Zone 2: grain growth zone In the grain growth zone‚ it is observed that grains are just starting to form and grow‚ and that there are many open grain boundaries
