Product Parameter

Square Steel Tube: Square and rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.

RHS and SHS tube are a welded structural grade tubing,depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs.

Square hollow section is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, frames, etc. Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels.

① The usual delivery length of square and rectangular tubes is 4000mm-12000mm, mostly 6000mm and 12000mm. The square rectangular tube is allowed to deliver short-length and non-fixed-length products not less than 2000mm, and it can also be delivered in the form of an interface tube, but the buyer should cut off the interface tube when using it. The weight of short-length and non-fixed-length products shall not exceed 5% of the total delivery quantity, and for square and rectangular pipes with a theoretical weight greater than 20kg/m, shall not exceed 10% of the total delivery quantity

② Process classification According to the production process, square and rectangular pipes are divided into: hot-rolled seamless square pipes, cold-drawn seamless square pipes, extruded seamless square pipes, and welded square pipes. 1. According to the process - arc welded square tube, resistance welded square tube (high frequency, low frequency), gas welded square tube, furnace welded square tube 2. According to the welding seam - straight seam welded square tube, spiral welded square tube.

③ Material classification The square tube is divided into: ordinary carbon steel square tube, low alloy square tube. 1. Common carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc. 2. Low alloy steel is divided into: Q345, 16Mn, Q390, ST52-3, etc. Production Standard Classification According to the production standard, the square tube is divided into: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube, and non-standard square tube.

1787637561950754604130836480.jpg@!w400Galvanized steel square pipe tube is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Galvanizing is a well-known and effective method to add a protective layer to prevent the exposed steel from being corroded by natural elements. Zinc not only acts as a barrier between the environment and the steel, but it also decomposes first to protect the underlying steel and extend its service life. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. Z275 means that the galvanizing content is 275 grams per square meter, and so on. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter.

Description of application effect

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels. Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.
