1.What is ERW rectangular tube?
ERW rectangular tube refers to a type of rectangular hollow structural section(HSS) that is manufactured using the Electric Resistance Welding (ERW) process.
(1)What is hollow section?
Hollow seaction refer to metal materials with a hollow cross-section. Compared with solid profiles, hollow sections are lighter, but have better performance in terms of load-bearing capacity and high strength. Rec-tube and square tube are common HSS. According to the raw materials, it has two different types: carbon and stainless steel.
ERW rectangular pipe is divided according to the welding method. Rectangular tube is a square rectangular tube, also known as a rectangular hollow section (RHS), is a type of hollow tube with a rectangular cross-section.
(2)ERW meaning for rectangular steel pipe
ERW means Electric resistance weld tubing, which is a pipe production method that uses the principle of resistance heating to apply electric current at the joints of steel coils to generate heat to locally melt the metal, and then connect the two steel coil heads together. Rec tubes are produced in this way.The ERW method is efficient, fast, and economical, and is widely used in various fields.
2.Characteristics and applications of ERW rectangular tube
(1) Strong and reliable
Hollow erw rectangular tube has excellent strength and load capacity, and is suitable for areas with high strength requirements such as construction.
(2) High cost performance
The ERW manufacturing process is economical and fast, which makes this metal pipe highly cost-effective and the main choice for various structural and industrial products.
(3) Accurate size and beautiful appearance
ERW rectangular tubes are produced with precise dimensions and tight tolerances, ensuring uniformity in size and shape. At the same time, the metal piping has clean lines and meets modern aesthetic needs. It is sometimes used in building facades, interior design elements, and furniture manufacturing.
(4) Be flexible
Because this steel pipe adopts ERW's standardized production method, it is easy to integrate with various manufacturing structures, such as using welding, bolts, etc. for connection, providing great flexibility.
3. How to choose China ERW rectangular tube supplier?
(1) Have a complete pre-sales and after-sales system
The service system includes pre-sales, during and after-sales. If a hollow section factory does not have an independent customer service department, the entire procurement process cannot be well protected. Especially in the aspects of delivery tracking, logistics tracking, and after-sales service, it is easy for omissions to occur.
(2) Have a complete quality control production process.
Quality control production process is the basis for stable quality. However, many small exporters do not separate this link and directly confuse production with quality control, which can easily mix defective products and damage the interests of consumers. Therefore, it is important to have a professional quality control team.
(3) Regularly update and provide third-party testing reports
The most direct way to know whether a steel pipe exporter is trustworthy is to ask them if they have a third-party inspection report, and then see if the date on the report is within the past year.
(4) Provide customers with quality guarantee certificates
Manufacturers that can provide customers with quality assurance certificates are responsible. Generally speaking, the larger the manufacturer, the better the details in all aspects are done, so before purchasing, you can ask the manufacturer whether it has a quality guarantee.
