The material of hot-dip galvanized Electrical Metallic Tubing (EMT) conduits is predominantly strip steel, specifically Q195 or Q235 steel. Here is a comprehensive analysis of the material of hot-dip galvanized EMT conduits:

1. Main Materials

Q195 or Q235 strip steel serves as the primary manufacturing material for hot-dip galvanized EMT conduits. This type of steel boasts excellent mechanical and processing properties, enabling it to meet the demands of applications such as wire and cable laying and fire extinguishing systems. Its robust characteristics ensure reliable performance in various industrial settings.

2. Surface Treatment

Hot dip galvanizing is an efficient anti-corrosion treatment approach. It forms a protective film by uniformly coating a high-purity hot-dip galvanized layer on the surface of the steel conduit. This treatment endows the conduits with strong corrosion resistance, significantly enhancing their durability and extending their service life. The galvanized layer acts as a shield, safeguarding the underlying steel from the damaging effects of corrosion.

3. Material Characteristics

• Corrosion Resistance: Thanks to the zinc coating on their surface, hot-dip galvanized EMT conduits exhibit remarkable corrosion resistance. They can withstand the corrosive effects of various harsh environments, ensuring long-term reliability and stability.

• Pressure Resistance: As a material for power pipelines, hot-dip galvanized EMT conduits possess excellent pressure resistance. They are capable of withstanding substantial pressures and loads, making them suitable for use in demanding applications.

• Workability: Hot-dip galvanized EMT conduits are easy to bend and saw, facilitating installation and construction processes. Their flexibility and ease of manipulation make them a preferred choice for contractors and installers.

• Non-combustible: Metal hot-dip galvanized EMT conduits are non-combustible, maintaining structural stability even in emergency situations like fires. This property ensures the safety and integrity of the conduit system in critical conditions.

4. Application Scenarios

Hot-dip galvanized EMT conduits find extensive use in both indoor and outdoor wire and cable laying, as well as in fire extinguishing systems. They are particularly suitable for scenarios where high corrosion resistance and pressure resistance are essential. Their versatility and reliability make them an indispensable component in the power pipeline field.In conclusion, hot-dip galvanized EMT conduits are made from Q195 or Q235 strip steel. After hot-dip galvanizing treatment, they exhibit outstanding corrosion resistance and pressure resistance, along with good processing performance and adaptability. These features make hot-dip galvanized EMT conduits a crucial material in the realm of power pipelines.
