In terms of service, our service is a "one-stop" way of working. We have our own A709 grade 36 bridge steel plate processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as A709 grade 36 bridge steel plate cutting, welding, drilling, galvanizing, etc., at the lowest cost.
The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.
Chinese grade of 20# steel plate: No.20American grade: ASTM1020Japanese grade: S20CGerman, British and French grades: C22, C20CMaterial No.: 1.0402, 1.0411Density: 7.85The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. A709 grade 36 bridge steel plate, 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.
The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel A709 grade 36 bridge steel plate. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.
As for the mechanical properties of A709 grade 36 bridge steel plate, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
