Selecting the right enclosure is essential for every electrical installation, as it ensures both safety and performance. Two of the most commonly used options are the metal box and the concealed box. While both protect wiring, their features and applications differ significantly, making it important to understand which one best fits your project.

Why Choose a Metal Box?

A metal box is built from durable materials like galvanised steel, offering superior strength and fire resistance. In case of sparks or faults, the enclosure contains flames, preventing fire from spreading. Another key benefit is grounding metal boxes allow fault currents to safely discharge, enhancing overall protection.

Their robust design makes them perfect for commercial and industrial settings, especially where heavy electrical loads, mechanical stress, or harsh conditions are involved. Modular varieties made with 19-gauge steel are exceptionally strong, ensuring long-term performance in demanding environments.

Benefits of Concealed Boxes

Concealed boxes, usually made from PVC, are valued for their aesthetics and ease of installation. They remain hidden in walls, giving interiors a clean, modern look. Lightweight and simple to install, they often feature pre-drilled holes and customizable sizes. These boxes are commonly used in homes, apartments, and offices where neat appearance and convenience are priorities. Additionally, they provide safety by reducing accidental contact with live wires.

Where Each Works Best

A metal box is the preferred option in industrial plants, factories, and commercial spaces, where safety, grounding, and durability are critical. Concealed boxes, on the other hand, suit residential and office projects, blending with interiors while keeping wiring safe and organized. Many modern projects use a mix of both—metal for high-safety zones and concealed for appearance-driven areas.
