Industry experience
Quality square pipe manufacturers
Yuantai Derun was the largest square pipe supplier in China
Our main square piping products include black steel square tube, hot galvanized square tube,ZAM coating square tube,pre galvanized square tube. What’s more, we have various kinds of special shaped square tube.We believe there will always be one for you.
High Production Capacity
High Precision
High Quality
High Efficiency
Square tubes have high tensile, impact, and bending strength, and can withstand large loads and pressures, making them suitable for making various structural components.
Because all four sides of the sq pipe&tube are flat, this adds stability to the structure.
The bending resistance of box tubings is stronger than that of round pipes.
Unlike round pipes, square section pipes are easier to stack and store, making transportation and storage more convenient. Circular pipes have rolling properties, making them inconvenient to stack.
After surface treatment such as hot-dip galvanizing, the corrosion resistance of the square tube is greatly improved, and its service life can reach more than 30 years.
The use of square steel pipes reduces the logging of wood and other vegetation, and is also a recyclable and environmentally friendly metal building material.
In our life and industry, square tubes are widely used in large buildings such as Hong Kong-Zhuhai-Macao Bridge, Yuantai Derun provide high quality square tube .
Square tube is widely used in building structures because of its excellent yield strength, tensile strength, elongation and corrosion resistance.Yuantai Derun supplied square tube for Cairo Administrative CBD, Egypt
In these high-tech fields, the high-temperature stability and mechanical properties of square tube have been fully utilized.Yuantai Derun's early square tubes were supplied to agricultural machinery factories in Henan, China。
Square tube are also widely used in the fields of Offshore photovoltaic bracket.
