1.What Is Galvanized Steel Trunking?

Galvanized steel trunking, also known as galvanised electrical trunking,

is a metal enclosure system used to manage and protect electrical cables in a building or facility. It consists of long, hollow channels made from galvanized steel sheets. The galvanization process involves applying a zinc coating to the steel, which enhances its corrosion resistance and extends its lifespan.

The primary purpose of galvanized steel trunking is to provide a safe and organized pathway for electrical cables. It helps to prevent damage to the cables, ensures efficient cable management, and protects against external factors such as moisture, dust, and physical impact.

Galvanised steel trunking is commonly used in various industries and applications, including commercial buildings, industrial facilities, data centers, and infrastructure projects. It is suitable for both indoor and outdoor installations, offering durability and protection in diverse environments.

JLH Electric’s galvanized trunking is available in various sizes, such as 50mm x 25mm, 100mm x 50mm, 100mm x 100mm, 150mm x 150mm, 200mm x 100mm, and more. Each length of trunking is typically 3 meters long and comes with a pair of couplers for easy installation and connection.

2. What Are Advantages of Galvanized Steel Trunking?

Galvanized steel trunking proves to be a reliable and efficient solution for managing and protecting electrical cables. Its corrosion resistance, excellent finish, longevity, additional protection, and competitive pricing make it a preferred choice in various industries and applications.

2.1 Corrosion Resistance

Galvanized steel trunking is highly resistant to corrosion. The zinc coating on the steel forms a protective barrier, preventing moisture, chemicals, and atmospheric elements from coming into direct contact with the steel. This corrosion resistance extends the lifespan of the trunking, reducing the need for frequent replacements or repairs.

2.2 Excellent Finish

Galvanized steel trunking has a smooth and visually appealing finish. Its clean and professional appearance enhances the overall aesthetics of installations, making it suitable for both functional and aesthetic purposes.

2.3 Longevity

The corrosion-resistant properties of galvanized steel trunking contribute to its longevity. The zinc coating forms a strong bond with the steel, providing excellent wear resistance. This ensures that the trunking remains durable and in good condition over an extended period.

2.4 ISO9001 Approved Factory

Some manufacturers of galvanized steel trunking have ISO9001 certification. This certification ensures that the trunking is manufactured using high-quality processes and adheres to strict quality standards. Choosing a product from an ISO9001 approved factory ensures that you receive a reliable and well-made product.

2.5Additional Protection

Galvanized steel trunking offers additional protection in outdoor environments. It provides resistance against UV rays, which can cause degradation and damage to certain materials. The trunking also withstands exposure to harsh weather conditions and chemical agents, making it suitable for outdoor installations where protection against these elements is crucial.

2.6 Competitive Factory Price

JLH Electric offers galvanized steel trunking at competitive factory price. Our galvanized cable trunking is the cost-effective choice for cable management needs, allowing for efficient and affordable installations without compromising on quality or durability.

3.How Thick is Galvanised Steel Trunking?

The thickness of galvanized steel trunking can vary depending on the specific requirements of the application and the manufacturer. However, here are some common thickness ranges for galvanized steel trunking:

3.1 For smaller trunking sizes or applications where weight is a major concern, the thickness may range from 0.5 mm to 1.5 mm. This thinner trunking is suitable for less demanding applications.

3.2 In many general applications, the thickness of galvanized steel trunking typically falls within the range of 1.5 mm to 2.5 mm. This range provides a good balance between weight and strength, making it suitable for various installations.

3.3 For heavy-duty applications that require greater strength and durability, some manufacturers offer galvanized steel trunking with thicknesses exceeding 2.5 mm. These thicker trunking options are designed to withstand more demanding conditions.

The above thickness ranges are general guidelines and may vary depending on the cable trunking manufacturer and trunking size. Any special requirement, please consult the our specifications for accurate information regarding the specific galvanized steel trunking you are considering.

JLH Electric offers the standard galvanized steel trunking sizes you mentioned, such as 50mm x 25mm, 100mm x 50mm, and 200mm x 100mm. We also provide custom gi cable trunking for your demand.
