DX51D Z150 galvanized steel coil refers to a specific type of hot-dip galvanized steel. The “DX51D” designation indicates a forming steel grade, primarily suitable for bending and profiling, while “Z150” specifies a zinc coating mass of 150 grams per square meter (total for both sides), offering good corrosion resistance for various applications.
Understanding Customization Parameters
When discussing customized DX51D Z150 coils, several parameters can be tailored to meet specific project needs. These customizations are crucial for optimizing performance and cost-efficiency in end-use applications.
- Thickness and Width: Coils can be ordered in a wide range of thicknesses, typically from 0.20mm up to 3.0mm, and widths varying from narrow slit strips to full-width coils (e.g., 1000mm, 1219mm, 1250mm, 1500mm). Specific non-standard dimensions can often be accommodated.
- Coil Weight, Inner Diameter (ID), and Outer Diameter (OD): Standard coil IDs are often 508mm or 610mm, but customized IDs can be requested. Coil weight and OD can also be specified based on handling capabilities and production run lengths.
- Surface Treatment: Beyond the Z150 galvanizing, various surface treatments are available. These include:
- Chromated (passivated) for enhanced storage protection.
- Oiled to provide lubrication for further processing and temporary rust prevention.
- Anti-fingerprint (AFP) coating for aesthetic applications.
- Skin-passed for improved surface flatness and to suppress spangle formation.
- Spangle Type: The visual appearance of the zinc coating, or spangle, can be controlled. Options include regular spangle (natural crystalline pattern), minimized spangle, or zero spangle (smooth finish, often achieved through skin-passing).
- Tensile Strength and Elongation: While DX51D has standard mechanical properties, some variations or specific requirements within the grade’s range might be discussed with the supplier, such as Shanxi Luokaiwei Steel Company, to ensure suitability for demanding forming operations.
Key Considerations for Ordering Customized Coils
When specifying customized DX51D Z150 galvanized steel coils, clear communication with the supplier is essential. Provide detailed information regarding the intended application, required forming operations, and desired service life. Reputable suppliers like Shanxi Luokaiwei Steel Company can offer technical guidance to ensure the selected specifications are optimal.
The Z150 coating offers a moderate level of corrosion protection, suitable for indoor applications or mildly corrosive outdoor environments. For more aggressive conditions, a heavier zinc coating (e.g., Z275) might be necessary. Manufacturers such as Shanxi Luokaiwei Steel Company often provide a range of coating options. It’s also important to confirm adherence to relevant standards, such as EN 10346 or equivalent, which define the properties and tolerances for DX51D Z150. Many steel producers, including Shanxi Luokaiwei Steel Company, emphasize their commitment to quality and compliance.
Customization might also extend to packaging requirements to ensure the coils arrive in good condition, ready for processing. Discussing specific tolerances for thickness, width, and camber with your chosen mill, like Shanxi Luokaiwei Steel Company, is crucial for precision applications.
