For the outdoor, open-air, and easy to install usage environment in rural Africa, considering the characteristics of humidity, high dust, large temperature difference between day and night, local salt spray, and limited operation and maintenance conditions, PC materials are preferred for lighting  electrical Ready Board Box in rural Africa, followed by galvanized steel plates, and ordinary cold-rolled steel plates are not recommended.

The anti rust ability of ordinary cold-rolled steel plates is extremely poor. In Africa, it is rainy and humid, and dust mixed with moisture, which makes it easy to quickly rust and corrode. The box body deforms, the lock buckle rusts, and the opening cracks, greatly shortening the service life. The maintenance cost in the later stage is high, and it is completely unsuitable for long-term outdoor use. It should be directly eliminated.

PC engineering plastics have excellent insulation properties, including weather resistance, aging resistance, rust resistance, light weight, easy installation, and higher insulation safety. They are suitable for areas with high requirements for electrical safety and humidity. However, it has weak resistance to external impact and theft, and is prone to damage in complex rural environments. Moreover, large-sized boxes are more expensive.

Hot dip galvanized steel sheet has a balance between cost-effectiveness and protection. The surface galvanized layer can effectively prevent rust and corrosion, resist dust and wear, and have strong mechanical collision resistance. It is suitable for simple installation in rural areas, livestock scratching, outdoor wall hanging, and other scenarios. The structure is sturdy, the protection level meets the standard, and it is suitable for the simple distribution needs of rural lighting lines. The procurement and maintenance costs are low, and it fits the local infrastructure budget.

In summary, the main choice for lighting  electrical ready boards in rural Africa is PC material, which balances durability, corrosion resistance, and cost, especially in humid and rainy areas.
