Product Description

Carbon Steel Pipe and Carbon Steel Tube

Shandong Zhuosheng stocks a variety of carbon structural steel grades in both steel tubes and pipes. Steel tubing size options include rectangular, round, and square. Structural carbon steel shapes are ideal for construction. The variety of shapes available, from I-beams to angle, as well as pipes and tubes all have high cross-sectional stiffness due to their second moment of area. Structural shapes can come in many materials, carbon steel is a good choice for when your project requires a high strength material and low-luster isn’t a concern.  Our most popular structural grade is ASTM A500 carbon steel tubing. ASTM A500 is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. A500 is the most common specification in North America for Hollow Structural Sections (HSS).

Carbon steel pipes are divided into two types: hot-rolled and cold-rolled (drawn) steel pipes.

Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (dial) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Rust thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipe can reach 6mm, and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

General carbon steel pipe: It is made of high-quality carbon steel such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steels or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels that are hot-rolled or cold-rolled. 10, 20 and other low carbon steel seamless pipes are mainly used for fluid conveying pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure strength and flattening tests. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.

shandong zhuosheng is a supplier and manufacturer of Steel hollow section from China. We export our products in more than 60+ countries. All products are available in various size as per client needs. The product that we supply are well coated with anti-rust oil in every surface of a hollow section to ensure rust free delivery of the product to the client. Steel hollow section is available in square, rectangular and circular shapes. The hollow structural section is standard in welded steel frames, particularly in rectangular sections, in which members experience loading in different directions. Square and circular HSS have very efficient forms to load this multi-axis as the two or more cross-sectional axis are uniform in geometry and therefore have uniform strength features. This allows them to make good column choices. They are also very torsional resistant. The Hollow Section (RHS SHS CHS) is produced in high quality and is strictly following the industry standards. Our product range is available in various dimensions and thickness to meet automotive, material handling, transportation and other requirements. Our company's hollow section is available in circular, rectangular and square shapes. Due to the features such as high resistance to wear and stress, these are widely demanded by the customers.

Rectangular Hollow Section(RHS)

For mechanical and structural applications, rectangular hollow sections (RHS) are popular. This is because the flat surface makes it a more economical structural solution for joining and different types of manufacturing work. For soldering or joining, RHS requires minimal edge preparation. Because of the rectangular shape of this type of hollow section, parts only need to be cut straight when joining to other flat surfaces. We produce good quality of Rectangular Hollow Section with the help of the latest technology and equipment and excellent raw material quality. We do not compromise with the quality of the product in any way. We understand important of the quality of a product is for users in meeting the requirements of the application. To satisfy all of the buyer requirement, we promise that we will deliver the best and top quality product to the customer so that we can get more deal in the future. We sell the product at the market-leading price, so buyers won't find it hard to buy goods in bulk.

Circular Hollow Sections(CHS)

The first form of the hollow section was circular hollow sections (CHS). It is used generally in a variety of structural, mechanical and building areas. The strength and weldability is good, with uniform mechanical characteristics. These hollow section pipes and tubes are used when a failure is not an option. This CHS is the fully certified product and is suitable for low temperatures applications. These are the few features and advantages of hollow circular pipes. CHS are also called round steel tubes, a common type of steel sections used in different formats over different industries. Circular tubes are used in various industries. We also provide different steel grades in the circular hollow section.

Structural Carbon Steel Application Information

As the carbon content rises, steel has the ability to become harder and stronger through heat treating, but this also makes it less ductile. In carbon steels, a higher carbon content reduces weldability and lowers the melting point. 


Carbon Steel Tube and Pipe Properties and Composition

As the carbon content rises, steel has the ability to become harder and stronger through heat treating, but this also makes it less ductile. In carbon steels, a higher carbon content reduces weldability and lowers the melting point.

Steel is commonly considered carbon steel when no minimum content is specified for any alloying element (for example, aluminum, chromium, nickel, molybdenum, vanadium, etc.) or any other element added to obtain a desired alloy effect. The manganese does not exceed 1.65%, the specified minimum for copper in not below .40% or exceed .60% and silicon does not exceed .60%.


Carbon levels are divided as follows:

low carbon = .06% to .25% carbon content (mild steel)

medium carbon = .25% to .55% carbon content (medium steel)

high carbon = >.55% to 1.00% carbon content (hard steel)



Carbon grades are available in the following grade series:

10XX = non-resulpherized carbon steel, with manganese 1.00% maximum (for example 1018, 1045 and 1050).

11XX = resulpherized carbon steel (for example 1117, 1141 and 1144).

12XX = rephosphorized and resulpherized carbon steel (for example 12L14 and 1215)

The second two numbers in AISI-SAE designations indicate the approximate carbon content for steel (for example, in 1018 the carbon range is .15% to .20%; .18% [shown as "18"] is the approximate carbon content).


Pipe and Tube Grades Available

A500 Tube (round, square and rectangular), A500 Pipe, A53 Tested Pipe, A106 HF Seamless Tube, A513-T5 DOM Round Tube, A513-T2 CREW Round Tube, A513-T1 HREW Round Tube, A519 CD Seamless Round Tube, A519 HF Seamless Round Tube, A787 Round Tube, J524 Seamless Round Tube, and J525 Welded Round Tube.
