Square-tube size and forming method
CARPORT GUIDE
One-sided forms and rods
A curved square-tube beam and offset column cover a single row, with bending and membrane joints to resolve.
FORM & FUNCTION
The square-tube form is also a one-sided cantilever, expressed with square hollow sections. Its flat faces and corners change beam, cross-member and membrane-clamp connections compared with round tube. A similar outline does not mean an identical fabrication list.
Square-tube size and forming method
Corner joints and membrane clamps
Bases, doors and drainage edges
Single-row sites with foundations along one edge and a frame language that fits neighbouring square-section elements.
Review how the square tube is bent or segmented, its wall thickness, welds, corrosion protection and membrane edge clamps. Keep bases clear of door swings.
Round and square tubes differ in section and joint details, not just finish. The beam and rear projection also differ from the T-shaped form.
QUESTION & ANSWER
No. This reference form uses a curved main beam. Fabrication capacity, splice positions and membrane curvature must be set by the manufacturer and design drawings.
