Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for Q310NQL2 atmospheric corrosion resistant structural steel various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several Q310NQL2 atmospheric corrosion resistant structural steel after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Cold rolled coil products Q310NQL2 atmospheric corrosion resistant structural steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products Q310NQL2 atmospheric corrosion resistant structural steel is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils Q310NQL2 atmospheric corrosion resistant structural steel with different surface roughness can be produced (glossy surface or matte surface, etc.).

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized Q310NQL2 atmospheric corrosion resistant structural steel are higher than that of annealed Q310NQL2 atmospheric corrosion resistant structural steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of Q310NQL2 atmospheric corrosion resistant structural steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

our company offered 2950 ton A36 steel Q310NQL2 atmospheric corrosion resistant structural steel plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
