Galvalume is a steel sheet product featuring a highly corrosion-resistant coating composed primarily of aluminum (approximately 55%), zinc (approximately 43.4%), and a small amount of silicon (approximately 1.6%). This alloy coating is applied through a continuous hot-dip process. Understanding the AZ55 Designation The designation “AZ55” is a standard industry term that refers to the coating […]

Z120 grade galvanized steel refers to hot-dip galvanized steel with a zinc coating weight of 120 grams per square meter (g/m²) total for both sides. This coating provides good corrosion resistance for various applications where a moderate level of protection is required. It’s a commonly specified grade in manufacturing and construction. Key Characteristics and Applications

ASTM A514 is a specification covering high-yield-strength, quenched and tempered (Q&T) alloy steel plates. These plates are primarily utilized in applications requiring a high strength-to-weight ratio, such as welded bridges and other structural components where reduced weight and high performance are critical. Understanding “Q” in A514 Q Plates The “Q” in A514 Q plates, or

AZ150 is a designation for a specific metallic coating applied to steel, primarily composed of an aluminum-zinc alloy. The “150” signifies a nominal coating mass of 150 grams per square meter (g/m²), distributed over both surfaces of the steel sheet. This coating significantly enhances the steel’s resistance to atmospheric corrosion, offering a balanced combination of

ASTM A36 steel is one of the most widely used carbon structural steels in construction and industrial applications. It is a low-carbon steel known for its good strength, formability, and excellent weldability, making it a versatile and economical choice for a variety of projects. Key Mechanical Properties ASTM A36 steel plate is characterized by the

Galvalume and Galvanized are two popular types of metallic-coated sheet steel designed to prevent corrosion. While both serve a similar purpose, they differ significantly in their coating composition, performance characteristics, and ideal applications. Coating Composition Galvanized steel is coated with a layer of nearly 100% zinc. This is typically applied through a hot-dip galvanizing process,

Understanding LSAW Pipes LSAW (Longitudinal Submerged Arc Welded) pipes are a type of steel pipe manufactured by forming steel plates into a cylindrical shape and then welding the longitudinal seam using the submerged arc welding (SAW) process. The term “longitudinal” signifies that the weld seam runs parallel to the pipe’s length. This method is distinct

AZ150 coating is a specific type of aluminum-zinc alloy coating applied to steel sheets, such as those that might be produced by specialists like Shanxi Luokaiwei Steel Company, to provide superior corrosion protection. The “AZ” signifies the aluminum and zinc composition, while “150” indicates the minimum coating mass of 150 grams per square meter (g/m²),

Understanding Pressure Vessel Quality (PVQ) Steel Pressure Vessel Quality (PVQ) steel refers to a range of carbon and alloy steel plates specifically designed for use in the fabrication of welded pressure vessels, boilers, and other equipment intended to operate under pressure. These steels are engineered to withstand internal or external pressure at various temperatures, ensuring

Submerged Arc Welded (SAW) pipes are a significant category of steel pipes manufactured through the submerged arc welding process. This technique involves creating an arc between a continuously fed electrode and the workpiece. The weld area is shielded by a blanket of granular fusible flux, which melts to protect the molten weld pool from atmospheric
