As the core equipment for power distribution, the choice of shell material for lighting electrical ready boards directly affects the safety, durability, and environmental adaptability of the equipment. Currently, PC material and hot-dip galvanized steel plate are two mainstream shell materials, with significant differences in performance, cost, and application scenarios.

PC materials: lightweight and insulation advantages

PC (polycarbonate) material is known for its high strength, impact resistance, and insulation properties. Its shell has high transparency and can replace glass for transparent observation. At the same time, its flame retardancy reaches B2 level, effectively reducing the risk of fire. In outdoor environments, PC materials have better thermal conductivity than metals and can reduce damage to internal components caused by high temperatures. In addition, the PC casing is lightweight, easy to install and transport, and suitable for scenarios that require load-bearing capacity. However, the surface of PC materials is prone to scratches, injection molding processes are complex, raw material costs are high, and long-term exposure to strong ultraviolet environments may cause aging.

Hot dip galvanized steel sheet: corrosion resistance and structural strength

Hot dip galvanized steel sheet forms a protective layer by galvanizing the surface of the steel sheet, significantly improving its corrosion resistance, especially suitable for humid or dusty environments. It has high structural strength, can resist external impact, and protect the safety of internal components. During processing, steel plates can be bent and spot welded into complex shapes to meet customized requirements. For example, the outdoor wall mounted electrical ready board produced by a certain manufacturer is made of 1.5mm thick galvanized steel plate, which is treated with high-temperature baked resin powder coating, combining aesthetics and protection. However, metal materials are heavier and require additional consideration for installation and fixing methods, and their cost is higher than that of PC materials.

Suggestions for selecting application scenarios

PC materials are more suitable for indoor or lightweight demand scenarios, such as household lighting electrical ready boards, as their insulation and lightweight properties can reduce safety hazards. And hot-dip galvanized steel plates dominate the outdoor and industrial fields, such as road lighting distribution cabinets, whose corrosion resistance and structural strength can cope with harsh environments. Some high-end products adopt a composite design, combining PC panels with galvanized steel plate frames, balancing aesthetics and functionality.
