Square & Rectangular Hollows

Square & Rectangular Hollows

Square and rectangular hollow sections (SHS and RHS) are tubular steel profiles used extensively in construction, fabrication, and structural engineering across New Zealand. With hollow cores and uniform wall thickness, these sections deliver high strength-to-weight ratios for framework, supports, and architectural applications in residential, commercial, and industrial projects.

Uses of Square & Rectangular Hollows:

Square and rectangular hollows are commonly specified for building frames, carports, pergolas, gates, fencing, and structural supports. Fabricators use them for trailer chassis, machinery frames, handrails, and architectural features. The hollow profile provides torsional rigidity while reducing material weight compared to solid sections.

Types of Hollow Sections Available:

Our range includes both square hollow sections (SHS) with equal sides and rectangular hollow sections (RHS) with different width and depth dimensions. Available in mild steel, galvanized, and structural grades to suit different load requirements and environmental conditions.

Specifications and Dimensions:

Hollow sections are sold by the metre and supplied in 6-metre or 7.5-metre lengths depending on size. Common SHS sizes range from 25x25mm to 150x150mm, while RHS dimensions span from 50x25mm to 200x100mm. Wall thickness typically ranges from 1.6mm to 6mm.

Features and Benefits:

• High strength-to-weight ratio reduces material costs and structural load
• Hollow core provides excellent torsional and bending resistance
• Available in square (SHS) and rectangular (RHS) configurations
• Galvanized options for superior corrosion resistance in outdoor applications
• Easy to cut, weld, and bolt with standard fabrication equipment
• Nationwide delivery available for project-scale orders
• Suitable for structural, architectural, and decorative applications
• Clean, modern aesthetic for exposed framework and design features
