Which materials are most suitable for high-durability trunking systems?

Selection depends on the installation environment. For standard commercial use, Pre-Galvanized Steel (DX51D) is preferred. In more corrosive or outdoor environments, Hot-Dip Galvanized (HDG) steel or Stainless Steel (SS304/SS316L) provides superior longevity. For lightweight or chemically volatile areas, high-impact Aluminum is often specified.
