Galvalume corrugated steel roof sheeting is a popular choice for both residential and commercial roofing applications due to its excellent combination of durability, corrosion resistance, and aesthetic appeal. Understanding Galvalume Galvalume is a steel sheet coated with an alloy composed primarily of aluminum (approximately 55%) and zinc (approximately 43.4%), with a small amount of silicon […]

Understanding Galvalume Coated Steel Sheets Galvalume coated steel sheets are carbon steel sheets continuously hot-dipped with an aluminum-zinc alloy. This coating typically consists of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. This specific composition offers a superior combination of properties, particularly in terms of corrosion resistance and heat reflectivity, when compared to

Galvalume refers to a steel sheet coated with an aluminum-zinc alloy through a continuous hot-dip process. This coating typically consists of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon by weight, offering a superior combination of corrosion resistance and heat reflectivity compared to traditional galvanized (zinc-coated) steel in many environments. Core Characteristics and Advantages The

G90 galvanized sheet refers to steel sheet coated with zinc using the hot-dip galvanizing process, with a coating weight of 0.90 ounces of zinc per square foot (total both sides) or 275 grams per square meter (total both sides). The “G” stands for galvanized, and “90” represents the coating weight. Key Properties of G90 Galvanized

G90 Galvanized Coil refers to steel coil that has been coated with zinc using the galvanization process, with a coating designation of G90. The “G90” designation indicates the amount of zinc coating applied to the steel, specifically 0.90 ounces of zinc per square foot (or 0.27 ounces per side) of the steel sheet. This measurement

G60 galvanized sheet refers to steel sheet that has been coated with zinc using the hot-dip galvanizing process, with a specific coating weight designation of G60. This designation indicates the amount of zinc coating applied to both sides of the sheet, measured in ounces per square foot. Here’s a breakdown of key aspects: Coating Weight:

G60 galvanized coil refers to a steel coil that has been coated with zinc to protect it from corrosion. The “G60” designation, as per standards like ASTM A653/A653M, specifically indicates the minimum total zinc coating weight on both sides of the sheet, which is 0.60 ounces per square foot (oz/ft²) or approximately 180 grams per

G550 Galvanized Pipe refers to steel pipe that has been coated with zinc using the hot-dip galvanizing process and conforms to a minimum yield strength of 340 MPa (50 ksi) and a minimum tensile strength of 550 MPa (80 ksi). The G550 designation indicates the coating weight, specifically a minimum of 550 grams of zinc

Understanding G40 Galvanized Steel G40 galvanized sheet refers to a specific type of hot-dip galvanized steel. The “G40” designation, primarily used under ASTM A653/A653M standards, indicates the minimum total zinc coating weight on both sides of the steel sheet. Specifically, G40 signifies a coating weight of 0.40 ounces per square foot (oz/ft²), which is equivalent

G40 Galvanized Coil refers to steel coil that has been coated with a zinc layer of G40 designation, according to ASTM standards. The “G40” specifies the coating weight, indicating 0.40 ounces of zinc per square foot (total both sides) of the steel sheet. Key Features and Benefits Corrosion Resistance: The zinc coating provides a barrier
