What Is a Steel Perforated Square Tube?
A perforated steel square tube is produced by adding holes to conventional square steel tubing through mechanical drilling, CNC punching, or laser processing. These holes can be designed according to specific installation needs, including fixed spacing, customized diameters, or end-position perforations.
Unlike standard tubes that require additional processing at the construction site, pre-perforated tubes arrive ready for assembly. This significantly reduces labor time while ensuring higher installation accuracy and consistency across projects.
Depending on environmental requirements, customers may choose different surface finishes, including black steel or galvanized steel perforated square tube options for enhanced corrosion resistance.
