1. Application of galvanized steel coil in the production of steel pipes and boxes

1 in 5 unmissable applications of galvanized steel coils is the production of steel pipes and steel boxes. The galvanized steel coil is the primary raw material for producing steel pipes and box steel. Steel boxes and steel products produced by galvanized steel coils have outstanding advantages, such as high durability, a long service life, resistance to harsh environments, and less prone to rust or corrosion. These two types of steel are commonly used in making water supply and drainage pipes, oil and gas pipes, vehicle parts, etc.

2. Application of galvanized steel coil in construction

Steel plays a very important role in the construction of structures. Galvanized steel coil has sustainable structures used as partitions, ceiling frames, and frame supports for houses and public buildings such as hospitals, schools, et cetera. Thanks to outstanding advantages such as corrosion resistance and anti-rust, galvanized steel coils are also the primary source of raw materials for producing ventilation pipes, purlins, deck floors, et cetera. Not only does it help to improve buildings with higher aesthetics, but it also creates living spaces with more open and transparent architecture.

3. Application of galvanized steel coil in the fabrication industry

It can be said that one of the 5 essential applications of galvanized steel coil is the manufacturing industry. A series of manufacturing industries that play an essential role in human life involves galvanized steel coils, such as electronics manufacturing, machinery manufacturing, printing, fuel extraction, et cetera. Galvanized steel coils are used to create essential tools that help the production process be completed quickly and efficiently. Thereby improving labor efficiency and contributing to the development of the economy.

4. Household industry - 1 in 5 essential applications of galvanized steel coil

It can be said that one of the 5 essential applications of galvanized steel coil is the application in the household industry. The household appliances industry affects people's daily lives innumerable. The galvanized steel coil is widely applied in producing household appliances such as televisions, phones, and refrigerators to simple kitchen appliances. All civil products are manufactured from components with galvanized steel to increase durability, prevent corrosion and oxidation, and external aesthetics for products. All civil products help people save time and free up labor in everything.

5. Application of galvanized steel coil in shipbuilding

Like in construction, galvanized steel coils are also widely used in shipbuilding. Galvanized steel coil specialized for constructing ships in the marine industry with high durability and resistance to sea salt corrosion. It mainly manufactures oil rigs, hulls, and repair ships. Galvanized steel coils can also manufacture heavy-duty ships carrying bulk cargo. It can be said that galvanized steel coils are an indispensable material for the marine industry.

Definition and Types of Steel Coils

Things You Want to Know About Steel Coils are sheets of metal that are rolled into large coils, making them easier to transport and use in various industries. These coils can come in different types based on their composition, surface finish, and manufacturing process. The two main categories are:

• Hot-Rolled Steel Coils

  Produced at high temperatures (above 1,000°F or 538°C), this type of coil has a rough surface finish and is used in applications like construction, shipbuilding, and automotive frames.

• Cold-Rolled Steel Coils

• These are hot-rolled coils that are further processed at room temperature to achieve a smooth finish, better precision, and higher strength. They are ideal for products requiring tight tolerances and a high-quality surface, such as appliances and furniture.

Galvanized Coils vs. Galvalume Coils

When discussing corrosion resistance, galvanized steel coils are coated with zinc, providing excellent protection against rust. Galvalume steel coils, on the other hand, are coated with a mixture of aluminum and zinc, offering even greater corrosion resistance and durability, making them popular in roofing and outdoor structures.

Applications of Steel Coils

Steel coils are used in numerous industries and applications:

• Construction: For structural components, roofing, and cladding.
• Automotive: In the production of vehicle frames, bodies, and parts.
• Appliances: For the fabrication of refrigerators, washing machines, and ovens.
• Pipes and Tubes: Steel coils are often formed into cylindrical shapes to make pipes and tubes.

 Benefits of Using Steel Coils

• Cost-Efficiency: Steel coils allow for bulk production, reducing costs in transportation and handling.
• Versatility: They can be cut or shaped into different forms for various applications, from heavy-duty construction to delicate precision parts.
• Strength and Durability: Steel coils provide excellent tensile strength, making them suitable for use in high-stress applications like automotive manufacturing and building materials.

Coil Thickness (Gauge) The thickness of a steel coil is measured in gauge (Gauge chart）. A lower gauge number indicates a thicker coil. For example, 16-gauge steel is thicker than 20-gauge steel. The choice of gauge depends on the intended application—thicker coils are more robust but heavier, while thinner coils are more flexible but less durable.

Steel Coil Storage: Best Practices

Proper steel coil storage is crucial to prevent damage, maintain quality, and ensure safety. Here’s a breakdown of the most important aspects to consider:

Storage Environment

The environment in which steel coils are stored plays a significant role in preserving their condition. Key factors include:

• Temperature and Humidity: Steel coils should be kept in a controlled environment with low humidity to avoid corrosion. Fluctuations in temperature can cause condensation, leading to rust.
• Ventilation: Proper air circulation is necessary to keep moisture levels down and to prevent any accumulation of condensation on the coils.
• Avoiding Direct Contact with the Ground: Coils should never be stored directly on the ground, as this can lead to moisture exposure. They should be placed on wooden or steel racks.

Vertical vs. Horizontal Storage

Steel coils can be stored either vertically or horizontally, depending on the available space and the type of coil.

• Vertical Storage: This is typically used for large, heavy coils. It saves space and makes handling easier, but requires proper racks to avoid any risk of the coil toppling.
• Horizontal Storage: Smaller coils are usually stored horizontally, stacked safely on top of one another, often on pallets or custom coil cradles.

Protection from Physical Damage

To prevent dents, scratches, or other physical damage, it’s essential to:

• Use Protective Covers: Coils should be wrapped in protective film or covers to prevent exposure to contaminants like dust, dirt, and moisture.
• Stacking Limitations: Avoid stacking coils too high, as this increases the risk of toppling or compressing the coils beneath. Heavy coils should always be stored at the bottom if stacking is necessary.
• Proper Handling Equipment: Coils should be handled with specialized equipment like coil tongs, C-hooks, or vacuum lifters to minimize physical damage during movement.

Labeling and Organization

• Clear Labeling: Each coil should be clearly labeled with information such as size, weight, material, and production date to facilitate easy identification and inventory management.
• First-In, First-Out (FIFO): Following the FIFO method ensures older stock is used first, reducing the risk of storing coils for too long and causing degradation.

Safety Measures

Steel coils are heavy and can pose serious safety risks if not stored properly.

• Secure Positioning: Ensure coils are properly secured to prevent rolling or shifting, especially in high-traffic areas.
• Storage Barriers: Use barriers or guardrails around storage areas to keep personnel safe and prevent accidental tipping of coils.
