Pre-Galvanizing Pipe is widely used in petroleum ,chemical industry, construction, shipbuilding, communications, electricity and underground gas pipelines and many other fields.
Pre-Galvanizing Pipe is galvanizing, Zinc layer is an electroplating layer, and zinc layer is separately stratified with the steel tube matrix.
Pre-galvanized steel pipe is the treatment of steel pipe before galvanizing: degreasing treatment, derusting treatment, phosphating treatment, drying treatment.
Hot dipped galvanized steel pipe is in manufacturing process using steel pipes of removed rust dipped into zinc liquid of 500℃ temperatures, and making steel surface attached zinc layer so as to achieve the purpose of anti-corrosion.
Hot galvanizing process specially suitable for kinds of strong-acid, alkali fog and other strong corrosive conditions. This kinds of fastener used a lot in outside of steel tower contribution.
Black steel pipes have a variety of use. Thanks to their strength and needs for little maintenance. They tend to be used for transporting gas and water to rural areas and urban areas or for conduits that protect electrical wiring and deliver high pressure steam and air. In addition, black steel pipes are also used in oil and petroleum industries for piping large quantities of oil through remote areas.
Other uses of black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. However, black steel pipes are never used for transporting potable water due to the fact that they tend to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well.

Seamless pipes are manufactured by extruding the metal to the desired length. Thus, they do not have any joint in its cross-section throughout its length. seamless pipes are marketed on an outdated myth that it does not have flaws but that welded has an inherent flaw throughout the length of each tube, as stated above. Intuitively this concept is easily accepted by purchasers and designers with limited experience with the various products.
Steel porp refers to the use of steel pipe, H-shaped steel, angle steel, etc. to enhance the stability of the engineering structure. Generally, it is an inclined connecting member, and the most common are herringbone and cross shapes. Steel supports are widely used in subways and foundation pits. Because the steel support can be recycled and reused, it is economical and environmentally friendly.
Steel coil is sheet metal supplied in coil form. Depending on the production method, such coil is classified as hot-rolled, cold-rolled, galvanised or polymer-coated . Steel coil is used across industry, the main consumers being the construction and machine-building sectors.
