Before you import steel, there are some thing you need to know. First, what’s the purpose of these steel pipes. You want to use the cargo as building material for construction, or for transportation, such as gas, natural gas, petroleum of other usage. For different usage need different kinds of steel pipe. Second, you should know some general kinds of steel pipe. Based on technique, there are two kinds of steel pipe, one is seamless steel pipe, the other is welded steel pipe. We can tell the difference literally. Seamless is the one without weld seam, and welded steel pipe is the one with one or multi-welded seams. But you must aware that there are two kind of seamless steel pipes.There are some factories who made fake seamless, which I mean, they used welded steel pipe, and then polish the welding beam, to make the welded steel pipe looks like seamless steel pipe, there is no impact on performance, but the cost for the fake one is lower than real seamless steel pipe. Although the fa...

Steel Beams’ Role in Civil Construction As a steel supplier for more than 30 years,Tianjin Xinyue Steel Group has witnessed a tremendous growth in the use of steel beams in construction. Steel have plenty more advantages over traditional wood beams, including faster installation, eco-friendly composition, and a safer role is construction. Considering how steel manufacturer can produce beams to fit precise specifications, they can be adapted to nearly any type of frame. In addition to the general frame of a civil construction, steel beams make an exception choice for ceiling beams. At the same time, steel can support heavier loads than wood, giving builders the opportunity to use fewer beams in roof construction. Although steel prices are typically higher than the cost of wood, the material may provide a better return on your investment. For one, since steel beams allow for faster construction, you can save more money on contractor services. Long-term savings are also a...

A guide to Galvanize If  you really cares about life span of your steel, you can take galvanized steel pipes into your consideration. The black steel pipe maybe very good, but because of weather and rain and other factors, steel pipe may corrosion rapidly. While with galvanize, lifespan of your steel pipe will be much longer than your expectation. Galvanizing is one of the best way of prevent steel pipe from corrosion. When steel pipe becomes corroded, it not only becomes unsightly, but may even lose its integrity. Typically, the galvanizing process consists of technicians adding a layer of zinc to the pipe. It is used on many types of pipes including seamless steel pipe and welded steel pipe. Thanks to the galvanizing procedure, steel pipes receives a buffer against damaging foreign elements like salt. As long as the zinc is not scratched away, the metal will be protected. When professionals galvanize your pipe, there are two essential ways that the zinc will defend ...

Why we choose steel instead of concrete in construction When a contractor have a building project in hand, which material to choose is a important decision to make.
