What is Square Hollow Section?

Square Hollow Section (SHS), a type of structural steel section, is available in a variety of sizes and walls. The steel pipes can be used for numerous purposes including signage, frames, benches, supports, and more. The steel tube is also known as a steel pipe. The galvanized steel pipe is zinc coated to resist rust and corrosion. Steel pipes are widely used in construction because they are strong and durable. Square Hollow Section steel pipes can be used to create a variety of shapes including round, square, rectangular, and more. The steel tube is available in a variety of sizes to meet the needs of any project.

Appearance of Square Hollow Section

External and internal surfaces of the Square Hollow Section must be free of fissures, cracks, material overlay, and nonmetallic contaminants. Small scratches, dents, a thin coating of welding cinder, or traces left after cleaning manufacturing faults are permissible so long as the wall thickness does not fall below the minimum acceptable limits. The weld must be compact and uninterrupted, with no fractures or other flaws that diminish its resistance below that of the underlying metal.

The exterior lip of the weld seam is removed. Within the approved range of diameter limits, seam thickening is permissible. The inside burr of the weld seam is not removed. Inadmissible is unevenness on the edges of the metal strip along the weld seam. Square Hollow Sections must have their ends cut perpendicular to their axis. As a result of the cutting process, it is allowed for the pipe ends to have a burr. Not permitted is pipe end deformation.

Advantages of Using Square Hollow Sections

Hollow sections are commonly used in construction and piping applications because of their many advantages. Structural pipes are typically made from steel, which is a strong and durable material. This makes them ideal for use in applications where strength and durability are required, such as scaffolding or support structures. In addition, steel is less likely to corrode than other materials, making it an ideal choice for use in outdoor applications. Hollow sections are also readily available from most hardware stores and can be easily cut to size with a saw. This makes them ideal for use in a variety of projects, from building temporary structures to repairing or replacing existing piping. Overall, the cost-effectiveness, availability, and simplicity of hollow sections make them a popular choice for many construction and piping applications.
