Aluminum Structural Plate

Aluminum structural plate is a durable, lightweight and easy-to-install alternative to labour-intensive reinforced concrete structures. There are no forms to set or remove. No curing time is needed. Large installation crews are unnecessary. No special lifting equipment is needed for small structures.

Aluminum structural plates are corrugated, curved and bolt-hole punched at the plant. Reinforcing ribs (if required by design) are also curved and bolt-hole punched to match the plate fabrication. Delivered to the job site unassembled, the plates and ribs are easily bolted together to form various shapes – round, vertical and horizontal ellipse, pipe-arch, underpass and arch.
