Prepainted Galvalume Coils
Prepainted Galvalume Coils are effectively utilized in industries with rigorous durability, strength, corrosion resistance, and aesthetics requirements. They can be shaped or coated with various coatings to meet specific needs and specifications. Rolled steel that has been painted with a protective ornamental coating is known as color-coated rolled steel (CCRS). In addition, it is possible to obtain a polymer coating in a variety of colors and a matte, luster, or ornamental natural finish. This collection of Prepainted Galvalume Coils is corrosion-resistant, has outstanding mechanical qualities, and can be shaped, profiled, or stamped to meet specific requirements.
Superior Material Composition and ProtectionUtilizing a base of cold rolled steel, this Prepainted Galvalume Coil is engineered with an ideal alloy mix for optimized protection: 55% aluminum, 43.4% zinc, and 1.6% silicon. The surface receives high-quality paint systems such as PE, SMP, PVDF, or Epoxy with paint thicknesses of 1525 microns on the top and 510 microns on the back, ensuring long-term corrosion resistance, abrasion prevention, and vibrant color retention in diverse environments.
Versatile Applications and CustomizationAvailable in widths from 600mm to 1500mm and thicknesses of 0.13mm1.50mm, these coils meet requirements for various industrial, architectural, and residential applications, such as roofing, cladding, appliances, and automotive parts. They are offered in standard RAL or custom colors, and finishes can be glossy, matte, or textured. Customization options and compliance with ASTM, JIS, and EN standards make them suitable for global projects.
Reliable Performance and PackagingWith a yield strength ranging from 240550 MPa, elongation between 1622%, and a Grade 1 adhesion rating (ASTM D3359), these coils excel in forming, bending, and roll-forming. Each coil is securely packaged for export, with PE film protection, anti-fingerprint treatment, and edge options (mill or slit). Storage life extends up to 12 months under recommended conditions, ensuring the product maintains quality during transport and warehousing.
FAQs of Prepainted Galvalume Coil:
Q: How is Prepainted Galvalume Coil manufactured to ensure high corrosion resistance?
A: Prepainted Galvalume Coil is manufactured using premium cold rolled steel coated with a specialized alloy (55% aluminum, 43.4% zinc, 1.6% silicon) which imparts exceptional corrosion resistance. Advanced paint systems (PE, SMP, PVDF, Epoxy) are applied in controlled layers to further protect the surface from environmental factors and enhance product longevity.
Q: What are the ideal applications for Prepainted Galvalume Coil, and why is it suitable for them?
A: These coils are ideal for roofing, cladding, building panels, appliances, and automotive parts due to their superior formability, high yield strength (up to 550 MPa), excellent corrosion protection, and wide range of color and finish options. Their durability and weather resistance make them suitable for indoor and outdoor environments.
Q: When should Prepainted Galvalume Coils be used over other coated steel products?
A: Prepainted Galvalume Coils should be chosen when projects demand strong corrosion and heat resistance, aesthetic versatility, and longevitysuch as in areas with harsh weather or industrial exposure. Their robust coating and range of finishes provide both structural performance and visual appeal.
Q: Where can the customized coils be used, and what dimensions are available?
A: These coils can be used in industrial, architectural, and residential sectors worldwide. Custom dimensionsthickness from 0.13mm to 1.50mm and width from 600mm to 1500mmaccommodate a variety of design and engineering needs. They are supplied according to international standards and project specifications.
Q: What is the process for ordering and receiving Prepainted Galvalume Coils?
A: Customers can specify requirements such as thickness, width, paint system, color, and packaging type. Once details are finalized, coils are produced to order, tested for quality parameters (adhesion, impact, elongation), and packed in standard export-ready packaging (eye to sky/wall, with PE film and anti-fingerprint protection) for global shipment.
Q: How does the product benefit users in terms of longevity and maintenance?
A: Coils are designed to withstand harsh conditions, with a storage life of up to 12 months under proper conditions. Their corrosion resistance and durable painted surface reduce maintenance frequency and costs. Additionally, anti-fingerprint and chromated surfaces enhance cleanliness and lifespan.
Q: What paint systems and finishes are available for Prepainted Galvalume Coil?
A: Available paint systems include polyester (PE), silicon modified polyester (SMP), polyvinylidene fluoride (PVDF), and epoxy. Finishes can be chosen as glossy, matte, or textured, with gloss levels ranging from 30% to 90%. This allows users to meet diverse design and functionality requirements.
