These channels are made from high-quality galvanized iron, offering excellent resistance to rust, corrosion, and termites. Compared to aluminum and wooden frames, GI channels are more cost-effective, easy to install, and have a longer lifespan. They are available in various gauges, typically ranging from 0.3mm to 0.55mm, making them suitable for different ceiling and partition applications.
