GI Conduit does have different grades. The grades or types of GI conduit are classified based on their thickness or gauge. The grades are typically labeled as heavy gauge, medium gauge, and light gauge. Each grade of GI conduit has its own applications, and the thickness of the conduit depends on the type of installation and the environmental conditions.
The heavy gauge GI conduit is the thickest gauge among the three. It is commonly used in industrial settings where rugged and reliable conduit protection is needed. Heavy gauge conduit has a wall thickness of 3.75mm to 4.5mm, which makes it durable and resistant to physical damage. Its thicker wall can withstand accidental bumped from heavy equipment or vehicular accidents. It is also resistant to exposure to corrosive substances making it perfect for outdoor installation.
Medium gauge conduit is the average thickness of the three grades. It has a wall thickness of 2.6mm to 3mm and is commonly used in commercial and residential areas. Medium gauge conduit is also durable, but not as rugged as heavy gauge conduit, making it ideal for installations that are not exposed to harsh and extreme conditions. Its affordability makes it an ideal choice for electrical installations that require less conduit protection.
Light Gauge Conduit has the thinnest wall thickness among the three grades. It has a wall thickness of 2mm to 2.5mm and is typically used in applications where weight and flexibility are essential. Light gauge conduit is commonly used in temporary installations and works in progress. It is also perfect for intricate electrical installations due to its flexibility.
In conclusion, GI Conduit comes in different grades, and each grade has its unique strengths and weaknesses. It is crucial to identify the right thickness or gauge of the conduit for a particular application to ensure its optimal performance and longevity. Contractors, engineers, and electricians must consider several factors in selecting the appropriate conduit gauge, such as the type of installation, environmental conditions, and budget.
