Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

What is the difference between Q235A steel and Q235B steel? First, The carbon content of Q235A steel is 0.22%, higher than that of Q235B steel, which is 0.20%. The sulfur content of Q235A steel is 0.050%, higher than that of Q235B steel, which is 0.045%. Second, P235GH steel welding, Q235 material belongs to carbon structural steel. The English letters A and B at the back have different meanings. They are impact temperature requirements. Q235A steel is not subject to impact, while Q235B steel is subject to 20 ℃ room temperature impact.

The company currently has a number of extended steel processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment, and can provide customers with diversified products and services. In addition, the company has strong technical force, complete production equipment and advanced production technology. The testing methods are perfect and the p235gh steel welding product quality is high.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. p235gh steel welding, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.

The company has huge steel p235gh steel welding products stock all the year round to meet the urgent needs of customers. For stock products, we can arrange delivery within 3 days. The transportation department and shipping department shall coordinate and follow up to update the progress to customers regularly, i.e. where the goods have arrived, so as to let customers not worry and rest assured. Think about what the customers think and what the customers are anxious about, solve problems for customers efficiently and effectively, is the direction of our unremitting efforts.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our p235gh steel welding products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
