Choosing the Right Material for Your Needs

The material of your junction box is a key factor in ensuring safety and durability for your specific application.

PVC & Plastic Junction Boxes

For residential and most indoor commercial wiring in Bangladesh, PVC junction boxes are the standard choice. Their main advantages are that they are non-conductive, which adds an extra layer of safety, and they are completely resistant to rust and corrosion. This makes them an excellent, long-lasting option for the humid local climate.

Metal Junction Boxes

Metal junction boxes are the heavy-duty solution, offering superior durability and protection against physical impact. They are also fire-resistant. These boxes are typically required when using metal conduit for wiring and are commonly found in workshops, garages, and commercial installations where a higher level of protection is needed.

Junction Boxes for Specialized Applications

Beyond standard indoor use, certain projects require specialized boxes for maximum safety and performance.

Weatherproof Junction Boxes for Outdoor Use

Standard junction boxes are not safe for outdoor installation. For any external wiring—such as for garden lights, water pumps, or security cameras—you must use a weatherproof junction box. These models feature rubber gaskets and securely fastening lids to achieve a high IP rating, guaranteeing protection against Bangladesh's heavy monsoon rains and high humidity.

Concealed Boxes for Wall Mounting

Often called "gang boxes," these are designed to be installed inside walls. Their purpose is to provide a secure mounting point for switches, sockets, and other electrical devices, allowing them to sit flush with the wall for a clean, professional, and safe finish in any room.
