what is the difference between EN39 S235GT and Q235 ?
EN39 S235GT and Q235 are both steel grades used for construction purposes. EN39 S235GT is a European standard steel grade that refers to the chemical composition and mechanical properties of the steel. It contains Max. 0.2% carbon, 1.40% manganese, 0.040% phosphorus, 0.045% sulfur, and less than ...Read more -
who is Black annealed steel pipe ?
Black annealed steel pipe is a type of steel pipe that has been annealed (heat-treated) to remove its internal stresses, making it stronger and more ductile. The process of annealing involves heating the steel pipe to a certain temperature and then slowly cooling it down, which helps to minimize ...Read more -

Type of Carbon Steel Pipe Coating
Bare Pipe : A pipe is considered bare if it does not have a coating adhered to it. Typically, once rolling is complete at the steel mill, the bare material is shipped to a location designed to protect or coat the material with the desired coating (which is determined by ...Read more -
What is RHS , SHS and CHS ?
The term RHS stands for Rectangular Hollow Section. SHS stands for Square Hollow Section. Less known is the term CHS, this stands for Circular Hollow Section. In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common ...Read more -
hot-rolled seamless steel pipe and a cold-rolled seamless steel pipe
Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel...Read more -
difference between pre-galvanized steel tube and hot-galvanized steel tube
Hot dip galvanized pipe is the natural black steel tube after manufacturing immersed in the plating solution. The thickness of the zinc coating is affected by a number of factors, including the surface of the steel, the time it takes to immerse the steel in the bath, the composition of the steel,...Read more -
Carbon steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its pr...Read more -
ERW, LSAW Steel Pipe
Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The production process of straight seam steel pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally hig...Read more -
what is ERW
Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe.Read more -
SSAW Steel Pipe vs. LSAW Steel Pipe
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, ...Read more -
Galvanized Steel Pipe vs. Black Steel Pipe
Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipe’s lifespan. Galvanized steel pipe is most commonly used in plumbing . Black steel pipe contains a dark-colored iron-oxide coating on its ent...Read more
