CT-Shape Specifications — 6 sizes
KS D 3502JIS G 3192
A T-section cut from an H-beam, used for trusses, brackets, and reinforcements.
Practical Notes
- Made by cutting H-beams — verify squareness and flatness of cut surfaces.
- When used as truss members, watch for buckling. T-sections are vulnerable to weak-axis buckling.

Key Features
- T-shaped cross-section cut from H-beam web center; produced without separate rolling
- When used as chord member: flange serves as compression face, web as connection face
- Dedicated truss top/bottom chord; web can be directly bolted without gusset plate
Key Applications
Steel truss chords, roof trusses, hangar structures, exhibition hall roofs, lightweight bridge superstructures
FAQ
How are CT sections made?
By flame-cutting (or oxygen-cutting) H-beams at the web center to create T-sections. Cut quality affects dimensional accuracy.
