Over the years, the company has established a standard of A709 Gr 100 bridge steel plate steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to A709 Gr 100 bridge steel plate quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
Structural steel for bridges is mainly used to make riveted and bolted welded bridge steel structures such as highway bridges, railway bridges, sea-crossing bridges, overpasses, viaducts, and large mechanical bridge cranes. A709 Gr 100 bridge steel plate, E grade bridge steel is suitable for low temperature and severe cold environment or bridge structural parts that are subjected to dynamic loads and the stress conditions of components are very complex and harsh.
A516 Gr65 steel is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard. A516 Gr65 plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. Our A709 Gr 100 bridge steel plate pressure vessel plate has good dimensional tolerance and surface quality.
Ultrasonic flaw detection emits ultrasonic waves to the A709 Gr 100 bridge steel plate steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the A709 Gr 100 bridge steel plate steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
