    A Guide to Coil in the Philippines

    A Guide to Coil in the Philippines


    • Steel coils are final steel products that have undergone rolling and subsequent coiling, categorized into hot-rolled, cold-rolled, and galvanized steel coils.
    • This material serves the automotive, construction, appliance, storage, transportation, and consumer goods sectors, offering versatility, structural integrity, and cost-effectiveness.
    • Steel coil types include hot-rolled (HRC) for downstream applications, cost-effectiveness, and portability, cold-rolled (CRC) for superior finish, and galvanized (GI) for corrosion resistance.

    Steel coils are the foundation for countless applications across various sectors. Their exceptional corrosion resistance and durability make them a cost-effective and reliable choice for construction, manufacturing, and infrastructure development. This comprehensive guide delves into the key features, production process, and diverse applications of steel coil in the Philippines.

    What Are Steel Coils?

    Stainless steel coils represent a final steel product, such as sheets or strips, that have undergone rolling and subsequent coiling. These coils are categorized into hot-rolled, cold-rolled, and galvanized steel coils, by contemporary products and global standards.

    Hot-rolled steel coils (HRC)

    This category of steel coils serves as the fundamental building blocks for diverse downstream applications. Derived from semi-finished steel, HRC undergoes a cost-effective process to reach the desired thicknesses. Consequently, these coils are easily transported and stored owing to their rolled structure.

    Cold-rolled steel coils (CRC)

    Representing a superior grade compared to their hot-rolled counterparts, cold-rolled steel coils (CRC) undergo a multi-step process to achieve exceptional attributes. This includes a superior finish, tighter dimensional tolerances, and enhanced mechanical properties such as increased strength.

    Galvanized steel coils (GI coils)

    Offering a cost-effective solution to bolster the performance and lifespan of steel products, galvanized steel coils (GI coils) feature a strategically applied zinc coating. This coating acts as a protective barrier, shielding the underlying steel from corrosion and various environmental factors.

    How Are Steel Coils Processed?

    How Are Steel Coils Processed?

    Steel coil processing involves a series of intricate steps to transform raw steel into various usable forms, each tailored to specific applications.

    Hot-Rolled Steel

    Hot-rolled steel is manufactured at temperatures exceeding 1,700˚F, making it highly malleable and conducive to enhanced workability. Production starts with a large rectangular metal piece called a billet, which is heated and flattened into a substantial roll. Maintaining high temperatures, the roll is fed through rollers to achieve final dimensions. The molten steel strands move swiftly through the rollers, with sheet metal coiled and left to cool, while bars or plates are sectioned and prepared for packaging.

    Cold-Rolled Steel

    Cold-rolled steel is essentially hot-rolled steel that undergoes further processing. Once the hot rolled steel has cooled, it is rerolled at room temperature to achieve more precise dimensions and enhance surface qualities.

    Galvanized Steel

    In the case of galvanized steel, the process involves the complete immersion of steel in a molten zinc bath. A chemical reaction at the surface forms a protective zinc-iron alloy layer, acting as the primary barrier against corrosion. Rapid cooling solidifies the zinc coating for enhanced durability.

    What Are Their Various Measurements?

    Steel coil dimensions are characterized by three key parameters:

    • Width: Measured in millimeters (mm) or inches (in), it defines the usable area of the uncoiled sheet.
    • Thickness: Also in millimeters (mm) or fractions of an inch (e.g., gauge), it determines the material weight and structural capacity of the steel.
    • Length: Typically in meters (m) or feet (ft), it reflects the total amount of material available on the coil.
      While width, thickness, and length are the primary dimensions, there are additional measurements that need to be considered.
    • Outside Diameter (OD): This crucial metric determines compatibility with machinery, storage facilities, and transportation. A coil’s size and weight directly influence these aspects.
    • Inside Diameter (ID): Equipment compatibility is vital, as certain machinery requires specific ID specifications for efficient operation. Additionally, ID impacts coil stability and handling during transport and storage.

    What Are Steel Coils Used For?

    Steel coils’ inherent properties – strength, versatility, and cost-effectiveness – make them a cornerstone material across diverse sectors:

    • Automotive industry: Steel coils fuel the high-volume production of car components like frames and body panels due to their excellent formability and affordability.
    • Construction: Their structural integrity and longevity make them ideal for roofing, wall cladding, and beams, ensuring reliable performance over extended lifespans.
    • Appliance manufacturing: The malleability of steel coils facilitates efficient shaping during the production of refrigerators, ovens, and washing machines, leading to streamlined manufacturing processes.
    • Storage and transportation: Steel coils’ robustness translates to secure and cost-effective solutions for storage tanks, containers, and shipping vessels.
    • Consumer goods: Finished steel coils offer an aesthetically pleasing option for furniture, shelving, and hardware, while also boasting the ability to withstand significant loads, making them a durable and cost-competitive choice.
