AS/NZS 2728 PPGL Coil – High-Durability Prepainted Aluzinc for Pacific Climates

Key Advantages of AS/NZS 2728 Compliant PPGL

1. Unmatched Colour Stability & Gloss Retention
Uniform Aesthetics: Adhering to strict gloss and color deviation limits (ΔE), our PPGL ensures a consistent look across different production batches.

Fade Resistance: Formulated to resist the harsh Southern Hemisphere sun, the coating maintains its vibrancy and texture after years of exposure, preventing the “patchy” look common in lower-grade steels.

2. Robust Physical Properties for Site Handling
Film Integrity: Our coils meet stringent impact resistance and scratch resistance tests. This ensures the protective film remains intact during roll-forming, long-distance transportation, and on-site installation.

Flexible Adhesion: Designed for precision bending, the coating will not peel or micro-crack, preserving the Aluzinc (AZ) sacrificial protection even at sharp ridges and eaves.

3. Optimized Corrosion Resistance (Categories 1-5)
Marine Grade Performance: Specifically tested for Corrosion Categories (C1-C5). Our AS/NZS 2728 PPGL is suitable for everything from mild inland regions to severe industrial and marine environments.

Long-Term Protection: The 55% Aluminum-Zinc alloy substrate provides a dense protective barrier, significantly extending the building’s lifecycle and reducing maintenance overhead.

AS/NZS 2728 PPGL Colour Coated Galvalume Coil Application Scenarios

Construction and Infrastructure Industry
This is the core application area of ​​this standard. Different types of PPGL products within the standard can be adapted to various scenarios inside and outside buildings, from ordinary civil buildings to industrial infrastructure and buildings in special environments. For example, in civil buildings, products conforming to the standard can be processed into roofing panels and wall cladding; this type of steel is commonly used as roofing and exterior wall material for high-end buildings.

In the industrial sector, the exterior walls and roofs of industrial plants, which need to withstand corrosion from industrial pollutants, will use products with stronger corrosion resistance from this standard.

General Manufacturing Industry
Many manufacturing scenarios that require pre-painted metal sheets and coils will refer to this standard to ensure product quality. For example, in the home appliance manufacturing industry, the casings of outdoor air conditioners and commercial refrigeration equipment, which are used outdoors or frequently, use PPGL products that meet the standard to resist daily friction and environmental corrosion, while maintaining their appearance and luster.

In the light manufacturing industry, products such as storage cabinets, shelves, and office furniture, by leveraging the standard’s requirements for paint film adhesion and scratch resistance, can avoid problems such as paint peeling and noticeable scratches during use.

1.what is AS/NZS 2728 Galvalume Coil

AS/NZS 2728:2013 is a joint Australian and New Zealand standard, titled “Prefinished/prepainted sheet metal products for interior/exterior building applications – Performance requirements.” It specifies the performance requirements for pre-coated (color-coated) metal sheets/strips used in construction. PPGL (Prepainted Galvalume Coil) refers to color-coated coils with a base substrate of 55% Al – 43.4% Zn – 1.6% Si aluminum-zinc alloy coated steel strip, which must meet the standard’s classification requirements for durability, appearance, and environmental suitability. It is commonly used in trade between Australia, New Zealand, and Southeast Asia.
