Galvanized square pipe tube

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.

① Flat incision

Multiple processing equipment. good raw materials and

processing technology from large factories, the cutting surface of the product is smooth and smooth without burrs, and the whole is beautiful and firm.

② Custom specifications

Product specifications variety large storage, adequate inventory, according to the need to map to sample customized different specifications length and shape, and equipped with a variety of processing technology

③ Not easily deformed

Reliable material, stable support bearing capacity under high pressure is not easy to use deformation fracture, long service life, cost saving

④ After-sale protection

Source factory direct supply spot, strict quality control, from warehouse to receive the whole process of quality control, quality assurance, can be assured to buy and use

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.

Square pipe and rectangular pipe application

Mainly used in engineering construction, glass curtain wall, doors and windows decoration, steel structure, guardrail, machinery manufacturing, automobile manufacturing, home appliance manufacturing, shipbuilding, container manufacturing, electricity, agricultural construction, agricultural greenhouses, bicycle racks, motorcycle racks, shelves, fitness equipment Water and gas, gas, sewage, air, heating and other fluid transportation, fire and support, construction and other fields.

Packing&Loading:

Normally packed in bundles with strong metal strips;

Bare or with woven bag or pupple film, or put in wooden crate;

If not in bunles, we put pipe in pipe or single pipe,

If pipe length ≤ 5.8m, loaded in 20' container,

If pipe length ≤ 11.8m, loaded in 40' container,

If pipe length > 11.8m, load on board by bulk FILO Terms.
