Technical Overview of ASTM A653 PPGI Coil (G60/G90)

Our ASTM A653 compliant Prepainted Galvanized Steel Coils are specifically engineered for the demanding requirements of the North American construction and industrial sectors. Unlike standard color-coated products, these coils utilize a high-purity zinc-coated substrate (Grade CS Type A, B, or Structural Steel) that ensures exceptional sacrificial protection against edge corrosion.

Zinc Coating Weight: G60 vs. G90

We provide precise control over the hot-dip galvanizing process to meet the stringent coating weight designations defined by ASTM A653:

  • G60 ($180g/m^2$): Optimized for standard outdoor applications, providing a balanced cost-to-performance ratio for roofing and wall panels.

  • G90 ($275g/m^2$): Designed for high-corrosive environments (coastal or industrial areas). The thicker zinc layer provides nearly 50% more service life compared to G60, meeting the highest durability standards for structural components.

Mechanical Properties & Formability

Following the ASTM A653/A653M standard, our coils are tested for:

  • Yield Strength: Consistent performance for structural reliability.

  • Ductility: Enhanced elongation properties allow for complex profiles without micro-cracking of the zinc or paint layers.

  • Flatness: Superior tension-leveled surface quality, critical for wide-span architectural cladding.

ASTM A653 PPGI Coil (G60 / G90) – Zinc Coated Prepainted Steel Application Scenarios

  • Construction Industry (Most Mainstream)
    Commercial and Industrial Buildings: Roofs and exterior walls of factories and warehouses; G60 is suitable for inland temperate climates, while G90 is suitable for coastal or industrial areas with high corrosion environments; structural components such as purlins, studs, and rainwater systems; G90 is more suitable for long-term exposure scenarios.Civil Buildings: Residential roofs, balcony railings, garage doors; G60 offers high cost-effectiveness, while G90 is used for seaside , and can be combined with PVDF coating to improve weather resistance and color retention.Industrial and Agricultural Applications
    Industrial Equipment: Ventilation ducts, electrical control cabinets, automation equipment housings; G60 is suitable for dry indoor workshops, while G90 is suitable for high-humidity or chemically corrosive production environments.
    Agricultural Facilities: Granaries, feed silos, irrigation troughs; G90 is suitable for high-humidity southern or coastal farms, improving corrosion resistance and service life.Commercial Decoration: Billboards, light boxes, interior decorative panels; G60 + customized color coating can balance aesthetics and cost.

FAQ about PPGI

1.what isASTM A653  G60 / G90 Galvanized Coil

ASTM A653/A653M is a standard issued by the American Society for Testing and Materials for continuous hot-dip galvanized / zinc-iron alloy coated steel plates and steel strips. G60/G90 are two of the main mainstream pure zinc coating weight grades, corresponding to a total weight of 0.6 oz/ft² and 0.9 oz/ft² on both sides respectively. They are widely used in fields such as construction, household appliances, and agriculture, and are suitable for different corrosive environments.
