Pre Galvanized Rectangular Hollow Steel Pipe Tube china steel
product description
Galvanized rectangular tube is a commonly used building material. It is made of galvanized strip steel, which is rolled by processing. Generally, the strip is unpacked, flat, crimped, welded to form a round tube, which is then rolled into a square tube and cut to the required length.
They usually come in packs of 50. Also known as square and rectangular cold-formed hollow steel, the surface is galvanized, with anti-corrosion, acid and alkali resistance, wear resistance, beautiful and other characteristics.
Handle design
1.The allowable deviation of the wall thickness of our galvanized square rectangular pipe shall not exceed 0.05mm when the wall thickness is less than 10mm, and 0.1mm when the wall thickness is more than 10mm, except the wall thickness of the corner and weld area
2.The usual delivery length of galvanized rectangular pipe is 4000mm-12000mm, mostly 6000mm and 12000mm. Square pipe allows the delivery of not less than 2000mm short size and non-fixed size products, can also be delivered in the form of interface pipe, but the buyer should cut the interface pipe when in use. The weight of short size and non-fixed size products shall not exceed 1% of the total delivery volume, and for square pipe with a theoretical weight greater than 20kg/m, it shall not exceed 2% of the total delivery volume.
Of course If the customer does not accept the joint pipe, our company can provide customers with free service to remove the joint pipe
Our product features
Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quadruple junction crystal, which forms a barrier on the steel plate and thus effectively prevents the penetration of corrosion factors.
Corrosion resistance The barrier layer from zinc provides strong protection. When zinc is sacrificed for protection in the cut edges, scratches and abrasion parts of the coating, zinc forms an insoluble oxide layer, which acts as a barrier protection

Advantages of galvanized rectangular pipe
(1) Strong anti-corrosion performance: in the production process, the outer surface of the square tube and the rectangular tube will be galvanized to form a layer of zinc on the surface. The thickness and quality of zinc layer have great influence on the corrosion resistance of steel pipe. In general, the greater the thickness of the zinc layer, the better the corrosion resistance, but the thickness of the zinc layer is too large will also affect the durability of the steel pipe.
(2) Strong acid and alkali resistance: the surface of the galvanized square tube has a certain acid and alkali resistance, which can be used in an acid and alkali environment and is not easy to be corroded.
(3) Beautiful and practical: galvanized rectangular tube is made of galvanized material, smooth surface, bright color, not easy to fade, beautiful and generous; It also has good wear resistance and toughness, safe and reliable use.
Application of galvanized square tube
(1) Construction field: galvanized square pipe also has more applications in building decoration. For example, partition, display rack, chair, door, steel and wood floor, etc., beautiful and practical.
(2) Agricultural field: In modern agriculture, the use of square tubes is more and more extensive. For example, steel frame greenhouse, fruit and vegetable shed, etc., are made of square control.
(3) Industrial field: It is also widely used in the industrial field. For example, oil, gas and other well pipes, air pipes, filter materials, etc., are made of square pipes.
In short, galvanized square rectangular pipe has the characteristics of corrosion resistance, wear resistance, good toughness, etc., widely used in construction, agriculture, industry and other fields, is an economic and practical material.
In recent years, with the rise of weddings and various outdoor activities, this product has also been well developed in these fields due to the convenience and practicality of galvanized rectangular pipe Our company is committed to connecting the world with steel trade, so that our products can bring better help to customers' business and local development
