In terms of service, our service is a "one-stop" way of working. We have our own 1.8988 material 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 1.8988 material cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. 1.8988 material Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's 1.8988 material requirements.

"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, 1.8988 material tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
