Top 10 Q355NH steel structure suppliers in China

ASTM A36 steel channel is hot-rolled, low carbon steel section with good properties including welding, machinability and ductility. A36 structural Q355NH steel structure channel have two types of sizes: UPN & UPE - tapered flanges and parallel flanges respectively. If you can't find the specific size in the table below, bespoke channel dimensions are available.The development Q355NH steel structure of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with Q355NH steel structure high-quality and efficient services, work together for win-win, and create a better tomorrow!How to distinguish between hot rolled and cold rolled process?
The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, Q355NH steel structure, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.Vanadium is a weak deoxidizer. Adding vanadium into Q355NH steel structure steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.Provide special product requirements to meet the personalized needs of customers.
