Based on the main EN10025-4 S420M steel plate business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel EN10025-4 S420M steel plate products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll EN10025-4 S420M steel plate, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the EN10025-4 S420M steel plate and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
