Q420qDNH Bridge Weathering Steel

Q420qDNH weathering steel is a carbon steel structural steel with weathering performance, which is weathering steel for bridges. Q420qDNH corten weathering steel executive standard: implement GB/T714 standard.

Advantages of Q420qDNH bridge weathering steel:
1. Good low-temperature toughness, which can meet the requirements of impact energy above 150J in -40℃ environment.
2. It has a high weather resistance index and can resist corrosion from the atmosphere, sea water, etc., extending its service life.
4. Low carbon design ensures good welding performance. There is no need to preheat during processing and can be directly welded, which is convenient for customers to install and produce later.
5. The delivery cycle is short, which can reduce production costs for customers.

Q420qDNH corten sheet has high strength and low impact temperature, which plays a great protective role in weather-resistant structural components. While ensuring the safety of the structure, it also greatly extends the service life and relatively reduces the cost of later maintenance.

Q420qDNH weathering steel general specifications thickness: 8mm-150mm, width: 1600mm-3900mm, length: 6000mm-14000mm.
