Product Overview & Key Features
Square Hollow Section (SHS) steel tube - sometimes called box section or square structural tubing - is a structural steel profile with equal side dimensions, offering balanced strength on both axes. It is one of the most commonly specified sections for columns, supports, and load-bearing frameworks due to its uniform cross-section and high torsional rigidity.
Key Features
- Uniform square cross-section for balanced structural strength
- High torsional and bending resistance compared to open profiles (angle, channel)
- Tight tolerance control on size, squareness, and corner radius
- Suitable for both welding and bolted connections
- Manufactured to ASTM A500, EN 10219-2, EN 10210, JIS G3466.

Formulas and Applications
SHS Weight Calculation Formula Weight (kg/m) = 0.00785 × t × (4A − 4t)
Where t = wall thickness, A = side length (mm). This square hollow section weight per metre formula lets you quickly cross-check any SHS weight chart or square pipe weight chart figure, or estimate tonnage for a custom SHS size not covered by standard tables.
Applications Structural columns, steel frame construction, fencing and handrail posts, greenhouse and poly-tunnel frames, solar panel mounting structures, scaffolding components, and industrial equipment supports.
Frequently Asked Questions (FAQ)
Q: What is SHS steel used for?
A: SHS (Square Hollow Section) is widely used for structural columns, fencing posts, solar mounting frames, and general fabrication where equal-axis strength and a clean square profile are required.
Q:What is the standard SHS size range?
A: Square hollow section sizes typically range from 20x20mm up to 400x400mm, with wall thickness from 1.5mm to 20mm depending on the size and grade.
Q:How is square hollow section weight per metre calculated?
A:Use the formula above, based on outer side length and wall thickness, or refer to our SHS weight chart for standard sizes.
Q: What's the difference between SHS and box section?
A: "Box section" is a common trade term for the same product as SHS (Square Hollow Section); both refer to a square structural steel tube.
