Our products NM500 steel used for bridges have strict quality inspection departments, so we have absolute quality and technical advantages. Good promotion system, with advanced business philosophy, create development space, enhance the value of employees, improve the quality of life as the mission. Pursuing green procurement, energy conservation and consumption reduction.The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of , Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.NM500 steel used for bridges,In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and NM500 steel used for bridges pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head Cold drawing is usually carried out on single chain or double chain cold drawing machines of 05-100t,NM500 steel used for bridges.NM500 steel used for bridges,Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.For employees' development,  the company's transformation and development provides employees with a broad career development platform The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities,NM500 steel used for bridges.We have been cooperated with the National Tubes Limited (NTL) in Bangladesh for many years. NTL is a state-owned company, so it needs to purchase needed steel materials by publishing tenders. Every time, we will participate the tender with our local agent and has been the winner for many times. In March 2020, we received their new order about , API 5L steel strips again, which will be used to produce tubes.
