Q690D Galvanized steel coil is a high strength welded structural steel. Wherein Q represents the yield strength, the yield strength value representative of 690, D level representative of the steel sheet.
GB/T16270 Q690D Carbon Structural Galvanized Steel coil may be referred to the yield strength 690Mpa resistance to low temperature high-strength steel. Q690D Galvanized Steel coil high yield and tensile strength, are widely used in mining machinery, engineering machinery, such as hydraulic support, port cranes, flatbed trucks.
