In many weathering steel sheets, different types of steel sheets will be used according to different applications. Among them, we encountered more weathering steel called q550nha. What are the characteristics of this steel plate? Today, we will discuss the
features of Q550NHA weathering steel.
Q550NHA steel structure has the unique advantages of high strength, good toughness, earthquake resistance, light weight, low price, small space, no consumption of civil engineering, light steel structure for residential buildings, short construction period, and fast capital turnover. Economic steel for concepts such as sustainable development. Welcome to send email to

Under natural climate conditions, steel can be eroded and thinned for more than 5 years, which is more serious in long-term or special humanistic environments. For another example, in order to prevent the strength of the steel structure from decreasing during a fire, the steel structure must be spray-painted or covered with a protective layer, and the one-time use can exceed the price of steel. Some are up to 65 mm thick and more expensive.
After using refractory materials and Q550NHA weathering steel, the fire protection layer was reduced to 15mm, less than 1/3, and the protection layer was removed from the outdoor column beams exposed by the department, while some large parking lots and sports fields did not use a protection layer at all.
Therefore, the Chinese steel grade Q550NHA weathering steel is expected to be put on the market as soon as possible. At present, Q550NHA weathering steel contains a specific composition, surface structure and microstructure through a suitable process, so that its own weather resistance and the refractory material itself are natural.
