Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, P235GH vs P265GH 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 p235gh vs p265gh International leading steel materials supplier.

Laser cutting p235gh vs p265gh 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 vs p265gh 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.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, p235gh vs p265gh has good atmosphere corrosion resistance.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel p235gh vs p265gh plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
