High weather resistance structural steel Q295GNH, Q355GNH adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal to improve the steel with atmospheric corrosion resistance. High weather resistance structural steel is mainly used in the structure of vehicles, containers, buildings, towers or other structural parts. Compared with welded structural steel P235GH steel for boiler, it has better atmospheric corrosion resistance.

Standing at a new historical starting point, we adapt to the requirements of supply side p235gh steel for boiler structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading p235gh steel for boiler steel materials supplier.

Laser cutting p235gh steel for boiler has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the p235gh steel for boiler cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of p235gh steel for boiler, wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
