Arctic H-beam applications focus on thermal stability:
Canada:
Cold-resistant H-beams (CSA G40.21 350W) with -40°C impact toughness support Inuit community buildings, tested in Nunavut's Arctic Bay.
Key Design:
Elevated H-beam foundations (HW300×300) maintain permafrost temperatures ≤-3°C via air convection, used in Alaska's Dalton Highway bridges.
