Q355GNH material steel sheet/coil specification

Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies Q355GNH material most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The Q355GNH material, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, Q355GNH material , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.

In year 2015, we ship 750 tons H beam to Pakistan for our old customer for building use. Because of urgent demand, the H beams are partial shipment by bulk vessel. Due to strong support of our customer, we also export many C channel steel, Q355GNH material I beam and other profile steel to local market.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our Q355GNH material products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
