What Is Square Steel Pipe
Square Steel Pipe, also referred to as Square Steel Tube or Square Hollow Section (SHS), is a hollow structural steel product featuring four equal sides and uniform wall thickness.
Types
ERW Square Steel Pipe
Manufactured using high-frequency electric resistance welding, ERW Square Steel Pipe is widely used for steel structures, warehouses, storage racks, machinery frames, fencing, and general construction where reliable structural performance and efficient production are required.
Cold Formed Square Steel Tube
Cold Formed Square Steel Tube is produced through precision cold roll forming and is widely used in structural engineering, industrial equipment, machinery manufacturing, automation systems, and other applications requiring uniform sections and easy fabrication.
Black Square Steel Pipe
Black Square Steel Pipe features a natural mill finish without surface coating, making it an economical choice for indoor structures, machinery frames, furniture, equipment supports, and products that will be painted or powder coated after fabrication.
ZMA Square Steel Tube
Coated with a Zinc-Magnesium-Aluminum (ZMA) alloy, ZMA Square Steel Tube is designed for long-term outdoor use in solar mounting systems, greenhouses, fencing, agricultural facilities, and other environments exposed to moisture and weather.
Bright Square Steel Pipe
Bright Square Steel Pipe features a clean, smooth surface and is widely used in machinery, fitness equipment, furniture, automotive components, display systems, and decorative metal fabrication where surface appearance is important.
