Material Choice: Mild steel with galvanization is cost-effective for general use; stainless steel or aluminum is preferred for corrosive or outdoor environments. Support Spacing: Ensure proper support intervals to maintain structural integrity and prevent excessive deflection under load. Fittings and Accessories: Use compatible elbows, tees, and reducers to maintain continuous cable support and proper routing.

Compliance: Verify that the selected tray meets local electrical and safety standards, including UL, IEC, or NEMA certifications.
