Rectangular Spec Table
Rectangular Specifications — 301 sizes
KS D 3568JIS G 3466ASTM A500
Rectangular-section hollow tubes used for beams, reinforcements, and machine frames.
Practical Notes
- Orient the long side in the load direction for greater section modulus and bending strength.
- More space-efficient than round pipe at equal weight; easier bracket welding.
Selection Guide
For beams and reinforcements needing directional strength. Orient the long side in the load direction for greater section modulus and bending strength. Suitable for machine frames, conveyor beams, and structural cross-members.

Key Features
- KS D 3568 (SPSR); long×short side ratio (e.g., 50×30–400×200 mm) provides directional rigidity
- High section modulus along long side optimized for beam applications
- High bending rigidity relative to weight; used in lightweight structures replacing H-beams
Key Applications
Conveyor support beams, stair railings, truck bed frames, door/window frames, shelf structures

Does orientation matter when using rectangular tubes as beams?
Very important. Orient the long side vertically (in load direction) to maximize section modulus. Opposite orientation greatly reduces strength.
