Q355GNH weathering steel plate rusts and does not corrode

Many metal materials rust due to oxidation, and later corrosion will lead to a decline in product quality and service life. But after production, the Q355GNH weathering steel plate is all red embroidered, and a black embroidered layer will be formed on the surface of the steel. This maintenance protects the Q355GNH weathering steel plate and prevents corrosion ions from entering the Q355GNH weathering steel plate.

Due to the presence of this embroidery layer, although the surface of the Q355GNH weathering steel plate is rusty, the inside will be corroded and isolated. But there is one more thing we need to understand. If you look closely, you will find that the embroidery of the Q355GNH weathering steel plate is relatively fine, just covering the whole body. It is this tightness that protects the inside of the Q355GNH weathering steel plate.

Q355GNH weathering steel plate has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving.

Q355GNH weathering steel plate is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, and towers.

Q355GNH weathering steel plate is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.
