Product Description
Square & rectangular pipes tube is an extruded pipes that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. Square tube has square corners inside and outside, with no weld seam.
Square & rectangular pipes tube are versatile, durable, and cost-effective building materials used in construction, industrial, furniture, and decorative applications. Womic Steel offers a wide range of steel square tubes in various sizes and thicknesses.
Rectangular/ Square hollow section are formed from the coils and then ran through a series of dies. They are are welded from the inside to form their shape.
Process of hollow section (Square/Rectangular tubes):
● Cold Formed Square Hollow Section
● Cold Formed Rectangular Hollow Section
● Hot Finish Square Hollow Section
● Hot Finish Rectangular Hollow Section
Production Process Classification of Square Steel Pipe
According to the production process, square pipe is divided into: hot rolled seamless square pipe, cold drawn seamless square pipe, extruded square pipe without dimension, welded square pipe.
The welded square / rectangular pipe is divided into:
(a) according to the process of an arc welded square pipe, resistance welded square pipe (high frequency, low frequency), gas welded square pipe, furnace welded square pipe.
(b) according to the weld of straight welded square pipe, spiral welded square pipe.
