we can offer a great variety of post processing services for your reference such as galvanizing, oiled, painted, powder coated as well as plastic-coated pipe. As steel pipe is widely used in different situations, further processing is necessary. For steel pipe with plain end that is in the rough, it can form threaded on both ends, one with socket, the other with cap by deep processing.

We have a professional pipe production & processing team. Our workers are all rich in practical experience for many years.

our team excels in grasping opportunities to expand our business scope including attending exhibition about 5-6 times home and abroad. Through different kinds of fairs, we can communicate with our customers face to face contributing to overall and comprehensive understanding about our company as well as our representative products. For example, Big 5 Fair in Middle East, Building Materials Exhibition in Vietnam.

as we have a process of welding when manufacturing, the surfaces of steel pipe may be not flat which can not meet the construction industry standards. In order to produce practical products, flattening weld joint applied to round steel pipes and square steel pipes is crucial to the overall manufacturing process. Our small steel pipes can be inserted in large scale pipes, besides, our steel pipes are equipped with other accessories as it seeks to prevent wires from scratching when threading.

With reference to pre galvanized steel pipe, before the zinc repair in the welding, we will first set out to remove the welding slag, zinc oxide skin and burned out layer. Then we use the spray painting for the repair of the zinc layer. We have the zinc repair in the welding close to the whole weld body in color, as a result of little color difference. Our finished galvanized pipe looks like much nature itself without blemish .

Our pipes undergo a Chromic Acid passivation treatment for the surface of galvanized steel pipe. As a rule, hydrogen treatment and passivation treatment are the two major methods for the final effective painting treatment of galvanized pipe, in order to further improve the corrosion resistance of the zinc layer or maintain the original property of the coating. Furthermore, it also helps to prolong the durable years of the pipes.

We always follow the principle of customer first. We are committed to everything from the customer's practical application needs. In actual purchase activities, according to the special requirements of different customers, our raw materials can be customized in order to apply to the specific application purposes in life. For example: scaffolding pipe: 48.3 * 3.2; 48.3 * 4.0 EMT conduit/ steel conduit pipe: 17.93 *1.07 zinc coating: 40g, 60g, 80g, ...200g

e have a series of practically complete pipe specifications for your choice. And in view of some special specifications, it is available for any customization. For instance: Australia: 76 *38; 65*65; USA: (UL) 17.93, 23.42, 29.54, and etc. India: 75 *25, 38 *25; Middle East: 125 *125, 150 *75.

we produce welded steel pipe. The weld line can be controlled with our precision instrument in the fitting place. For rectangular steel pipe, the weld line will exist in small sides in order to stand heavy weight. Customers who request factories produce rectangular steel pipes with weld line in small sides may have a project for steel doors or windows. Because the surface of big sides may be not even if it has weld line, that is not beautiful.

With skillful production experience and continuous innovation in the processing technology, our products have better quality assurance. For instance, our pre galvanized pipe looks much brighter, much smoother, and much flatter, conducive to the late processing treatment of pipes, such as painting, electrostatic spraying and etc, so as to ensure the better adhesion performance and nearly perfect surface effect of finished pipes.

you may encounter this kind of situation that you are in question about product quality before placing a large order. We , of course, can understand the way you are anxious about. In order to wipe off your doubts before concluding an order between us, we can send you a sample freely in advance lest the final products make you disappointed. We can ensure the sample is in accordance with the primary product including the thickness of zinc layer, pipe thickness, as well as other details

our factory is equipped with the tool of diamond roller for galvanized steel pipe. Diamond roller can control the shape of galvanized steel pipe in the process of production to make well-formed products used in construction industry. Customers who are very particular about product details such as the shape can have faith in our professional team and we will live up to your high standard. For large square steel pipes, we have combination roller equipment for manufacturing.

As a rule, foreign customers tend to distinguish the wall thickness of pipe as per different color coating in both ends of pipe. We have two major kinds of pipe body color treatment in foreign pipe market. One is to brush different colors to make a distinction between various wall thickness of pipe. This color treatment applies to both the black steel pipe and the pre galvanized pipe. And the other is to brush a color ribbon in both ends of pipe.

in mention of packing, we can offer a variety of methods for you to choose. Such is the fact , it is up to you about the number of steel pipes in a bundle. That is to say pieces of steel pipe are not fixed. Moreover, you can present your proposals about packing in order to make unloading easier. By the way, on the part of round steel pipe, the packing choice is limited. The bundle shape of round steel pipe is confined to hexagon, which is beneficial to loading and discharging products.

the thickness of galvanized steel pipe is thin with a lower price. As it has a thin thickness, the raw material is less used compared with that of hot dipped galvanized steel pipe. Hot dipped galvanized steel pipe is in contrary to the product of pre galvanized steel pipe in terms of price as well as their properties. According to preceding discuss, we have already known that the price of pre galvanized steel pipe is lower.
