Biggest Square Steel Pipe Manufacturer In China

There are many Big Macs in Hollywood movies. There are some industry giants in many subdivided fields in the steel industry. Tianjin Yuantai Derun Steel Pipe Manufacturing Group is a giant square tube company in China in the subdivided area of square tubes. Why is That? I think there are several reasons:

1. The Most Extensive Product Line

In China, you may not have seen any factory like Yuantai Derun. There are 110 production lines for square and rectangular steel pipe products, including 65 black high-frequency welded steel pipe production lines,  16 hot dip galvanized steel pipe production lines,9 pre-galvanized steel pipe production lines,8 photovoltaic support production lines,6 Zinc aluminum magnesium steel pipe production lines, 3 spiral welded steel pipe production lines, 2 production lines for zinc aluminum magnesium steel coils,1 LSAW steel pipe production lines,and 1 round to square extensive diameter steel pipe production line.

Large Diameter Square Steel Pipe Production Line

2. Full Specification Coverage

We have over 6000 specifications for square steel tube products alone, with outer diameters ranging from 10 * 10mm to 1200 * 1200mm and thicknesses ranging from 0.5mm to 60mm. Square steel pipe products are divided into standard pipes and non-standard customized steel pipes. With so many product specifications for square and rectangular steel pipes, there must be a type of square pipe that is suitable for your project.

3. Focus On Product Quality And Research And Development.

Focus on product quality and research and development. Over the past 21 years, Yuantai Derun has continuously invested in product research and development, constantly introduced talents, and built its own research and development and quality testing laboratory building. From raw materials to finished steel pipes, there are hundreds of processes that are strictly controlled, just to let you use a good steel pipe.

4.The Square Tube Leading Forming Process

Yuantai Derun Steel Pipe Group currently has internationally leading forming processes such as direct square forming and round to square forming.In order to meet the constantly improving requirements of our customers and purchasers, our forming engineers constantly break through technical difficulties and solve many steel pipe technical problems that are difficult for small workshops and factories to break through. If you have not yet purchased our steel pipes, please contact our customer manager immediately for consultation, obtain free samples, obtain technical guidance, and so on.     Contact Us Now!


What is square steel pipe called?

There are various names for square steel pipes, and the most common ones include box sections, square hollow sections, square tubings, square pipes, and so on. Essentially, they are all carbon steel square tubes, stainless steel square tubes, and alloy steel square tubes.
Is square steel tubing stronger than round?

The strength of circular and square pipes depends on the application scenario and force direction. Circular pipes are superior to square pipes in terms of bending and torsional strength, but square pipes have higher strength and stability under pressure. So circular pipes are mostly used for fluid transportation, while square pipes are mostly used for structural support.
What is the classification of square pipe?
Square tubes are divided into: 1. Simple section square tubes: right angle square tubes, arc angle square tubes. 2. Complex cross-section square pipes: flower shaped square pipes, open square pipes, corrugated square pipes, and irregular square pipes.
Square pipes are divided into: 1. Black square steel pipes: square pipes with no surface treatment. 2. Hot dip galvanized square tube: The surface of the square tube is coated with a layer of zinc, which enhances the corrosion resistance of the square tube. 3. Pre galvanized square pipes. It is a square tube directly produced from galvanized coils, with a zinc layer thickness less than hot-dip galvanized square tubes and weaker corrosion resistance.
How is square pipe measured?
The standard size of square tubing is usually called a specification, which indicates the outside diameter, wall thickness and length of the square tube. Square tube specifications are usually expressed as "outside diameter × wall thickness × length", e.g. 40 × 40 × 2.5mm × 6m.
What is the weight of square tubes divided into? How are they calculated separately?
The weight of square tubes can be divided into two types: theoretical weight and actual weight.
The theoretical weight can be calculated using the formula for calculating the weight of square tubes:
4 x wall thickness x (side length - wall thickness) x 7.85 kg/m
The actual weight of the square tube is measured by weighing.
