The company adopts the P235GH steel material international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety p235gh steel material management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. p235gh steel material Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the p235gh steel material steel plate.

Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, p235gh steel material and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This p235gh steel material rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The p235gh steel material, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
