Apollo Column is APL Apollo's range of hollow structural sections for structures of any design and elevation, offering high load-bearing capacity and strength-to-weight ratio. The rectangular box-section range is tabulated up to 900 mm x 1000 mm with thickness up to 40 mm (thickness below 30 mm corresponds to 500 MPa yield strength; 40 mm corresponds to 350 MPa); steel pipe length 8000-12000 mm. Only rows present on pp. 38-41 of this extract (brochure pp. 74-81) are listed as variants; the table continues beyond these pages.

Key features

• India's first 1000 mm x 1000 mm box section range
• thickness up to 40 mm
• Section properties listed for each size and thickness
• Higher torsional strength - the brochure states 200 times greater torsion resistance than open sections
• Uniform strength with no weaker axis
• high strength-to-weight ratio saves steel consumption
• Smooth profile - aesthetically pleasing and easy to paint
• Easy to install with conventional bolting
• easy to weld, punch, bend and drill
• Cut-to-length supply to avoid wastage
• Case studies report reduced steel consumption with customised APL Apollo tubular sections (about 25% at Prayagraj Airport, 20% design optimisation at Tirupati Railway Station)
