I am posting this question again.
I have designed a service platform with fiber glass grating with:
Live load 100 psf
Grating span 4 ft
Support beams C12 aluminum (11 ft span)
Support Columns 4 inch aluminum pipe
Approximate Area 500 sq ft
I am revising the support beam and columns materials to Stainless Steel or Fiber Glass.
I would like to know the cost comparison. Can any body inform me approximate costs per lb for aluminum, stainless steel and fiber glass alternatives?
Thanks!
