Box Beam

Box Beam industrial roofing and siding are commonly used for industrial warehouses and buildings requiring cryogenic/ temperature control. Box Beam is stronger than our 4” Box Rib.

Notes

  1. Roof loads are for positive loads only and are in addition to weight of panel.
  2. Other gauges of steel and aluminum are available upon inquiry.
  3. Maximum allowable stress for Grade A (F) = 20,000 PSI for roofs and 26,667 PSI for walls where wind is the only load.
  4. Loads and spans for carbon steel are based on the AISI Cold Formed Steel Design Manual.
  5. Other gauges of steel may be available upon inquiry.
  1. Roof loads are for positive loads only and are in addition to weight of panel.
  2. Other gauges of steel and aluminum are available upon inquiry.
  3. Maximum allowable stress (FC) = 15,000 PSI, (FT) = 17,000 PSI for roof and side wall. Stresses have been increased 1/3 for wind loading.
  4. Loads and spans for aluminum are based on Aluminum Formed Sheet Building Sheathing Design Guide.
