Careo 7035 Square WPC Hybrid Aluminum Post (3 3/8″ x 3 3/8″)
The Geolam Careo 7035 is a substantial hybrid architectural element measuring 3 3/8″ x 3 3/8″, combining an anodized aluminum alloy core (A6063S-T5 Series 6000) with a wood/polypropylene composite (WPC) outer skin through Geolam’s exclusive co-extrusion process. Its near-square profile delivers bold visual presence and a secondary moment of 65.95 cm⁴ on all axes, making it a versatile choice for architects who need a prominent yet proportionally balanced profile across exterior façades, pergolas, sunshade systems, and decorative screens. The sanded WPC grain finish replicates the warmth of stained hardwood with zero maintenance and long-term dimensional stability. Available in custom lengths from 7 ft to 19 ft 8 in.
