In 2019, our company has decorated the office building for newlook We also make the cultural wall with various photos These photos are a combination of BBN Group various activities that record the company's beautiful memories in recent years Among them are photos of the company's annual meeting, photos of group trips, pictures of factories, party pictures, photos of outdoors organized barbecues, photos of winter sports, pictures of table tennis matches The BBN steel company has rich staff activities and pleasant staff life,RINA grade D stern frame steel.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

The pipeline steel coil and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.RINA grade D stern frame steel

In April 2018, our Philiphine customer purchased 1008 Tons API5L Gr.B ERW&Q345B SMLS pipe for offshore oil field resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.RINA grade D stern frame steel

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.RINA grade D stern frame steel

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

The mechanical properties of boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.RINA grade D stern frame steel

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.RINA grade D stern frame steel
