Steel is widely used for industrial-grade secondary distribution boxes due to its exceptional mechanical strength, impact resistance, and electromagnetic shielding. It is ideal for harsh environments such as factories, construction sites, and utility substations. To prevent rust, steel boxes are often powder-coated, galvanized, or epoxy-finished, extending their lifespan and maintaining structural integrity . Steel also provides excellent fire containment, preventing internal electrical fires from spreading . Aluminum is a lighter alternative to steel, offering natural corrosion resistance through a passive oxide layer. It is suitable for outdoor or mobile installations, rooftop units, and telecommunications cabinets. Aluminum is non-magnetic, thermally conductive, and fully recyclable, making it a sustainable choice. While slightly less rigid than steel, modern aluminum alloys provide sufficient strength for most electrical distribution needs .
Thermoset plastics like SMC (Sheet Molding Compound) and fiberglass-reinforced plastics are excellent for high-voltage, outdoor, or corrosive environments. They maintain insulation and structural integrity under high heat, are flame-retardant, and resist rust and chemical damage. However, they are more expensive and non-recyclable . Engineering thermoplastics such as polycarbonate, PVC, and HDPE are lightweight, corrosion-resistant, and suitable for indoor or moderately exposed outdoor applications. Polycarbonate is particularly impact-resistant and UV-stable, making it ideal for areas with sunlight exposure. PVC and HDPE are cost-effective, non-conductive, and easy to install, but may have lower fire containment compared to metals .
