  • Product Detail

Weathering steel Q235NH weathering steel can be drawn and processed, that is, atmospheric corrosion resistant steel, which is a low alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel added. It has the characteristics of toughness, plasticity, forming, welding and cutting, wear resistance, high temperature resistance and fatigue resistance of steel. ; The weather resistance is 2~8 times that of ordinary carbon steel, and the paintability is 1.5~10 times that of ordinary carbon steel. Can be used for thinning, bare or simplified coating. Steel has the characteristics of rust resistance, corrosion resistance, thinning and consumption reduction, labor saving and energy saving.

Q235NH steel plate application:

Q235NH steel plate has a protective layer of rust resistance to atmospheric corrosion, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel.
Compared with carbon steel plate, Q235NH steel plate has better corrosion resistance in the atmosphere.
Q235NH steel plate is mainly for railway, vehicles, bridges, towers and other exposed steel used in the atmosphere.
Q235NH steel plate can also be used in the manufacture of containers, rolling stock, oil derrick, harbor construction, oil platforms and oil equipment chemical containers and other structures containing hydrogen sulfide corrosion medium.

FAQ

Q: Can we get sample?Any charges?
A: Yes,you can get available samples in our stock. Free for real samples, but customers need to pay the freight cost.
Q: How can we get the offer?
A: Pease submit the required steel grade, size, quantity. And we will check price for you at the first time.
Q: Do you handle pre-rusted process treatment yourself?
A: Yes, we are a professional corten steel products manufacturing factory providing full set of manufacturing service including laser cutting, NCT punching, bending, welding, grinding, polishing, pre-rusted treatment, etc.
Q: Why need pre-rusted treatment for the corten steel?
A: It takes long time to develop the stable rusty layer in nature. It can greatly affect the finish beauty of the corten steel,
especially the dropping of rust liquid and the flying of floating rust at the beginning of bare using. And pre-rusted treatment
can help the corten steel to be weathered in a short time and the color also can be controlled.
Q: Do you make customized products based on our design drawings or ideas?
A: Yes, we are a professional cortensteel manufacturing factory with an experienced engineering team to make customized products according to clients' drawings and ideas.
Q: What's your payment terms?
A: 30% down payment by T/T and 70% balance by T/T or L/C.
Q: What's your delivery time?
A: 15-45 days after receiving the down payment or L/C.
Q: Can you cut the steel plates to small pieces and drilling according to my drawing?
A: Yes. we also provides steel machining: Grinding, Welding, Planing, Rolling, Punching, Milling, Cutting, Drilling,
Turning.
