As global construction standards become more demanding, only a small number of Chinese manufacturers have successfully passed both AS2047 (Australia) and NZS4211 (New Zealand) certifications. These two standards are among the most comprehensive and rigorous testing systems in the window and door industry, covering wind load resistance, water penetration, airtightness, structural integrity, and safety glazing.
Yet, despite the size of China’s manufacturing sector, factories capable of achieving both certifications remain rare.
Why Are Dual-Certified Factories So Limited?
1. Extremely strict testing requirements
If any single performance indicator—wind pressure, water tightness, airtightness, or structural strength—fails, the entire system must be redesigned and retested.
2. High manufacturing and engineering capabilities
Dual-certified systems require:
High-strength aluminum profiles
EPDM sealing systems
Reliable hardware performance
Double or triple Low-E glazing
Stable thermal-break structures
Only true factory-direct manufacturers are able to deliver consistent performance across the entire system.
3. Understanding local building codes
Including:
Australia NCC
AS1288 & AS/NZS 2208 glazing standards
New Zealand H1 energy-efficiency requirements
M&C Windows & Doors: One of the Few Dual-Certified Manufacturers in China
Among Chinese manufacturers, M&C Windows & Doors stands out as one of the few factories capable of providing fully certified AS2047 and NZS4211 window & door systems.
① Fully certified systems—not just single product models
M&C offers certified sliding doors, casement windows, awning windows, bi-fold doors, and façade systems suitable for high-rise apartments, commercial projects, and luxury homes.
② Factory-direct supply to Australia & New Zealand
M&C has long supported projects in:
• Sydney
• Melbourne
• Brisbane
• Auckland
• Christchurch
with engineering consultation, system design, and on-site installation support.
③ Built for structural strength and extreme weather performance
Including:
• T5/T6 aluminum
• EPDM seals with 10-year stability
• Marine-grade hardware
• Double & triple Low-E glazing
• High-strength thermal breaks
Ensuring reliable performance in coastal environments and high-wind-pressure zones.
Why Developers Prefer Dual-Certified Factories?
Because dual certification guarantees:
• Stronger structural stability
• Superior water and air tightness
• Easier compliance with NCC and NZ H1
• Faster project approval
• More reliable installation and long-term performance
Essential for high-rise and coastal projects.
Only a handful of Chinese window & door factories hold both AS2047 and NZS4211 certifications.
M&C Windows & Doors is one of the few that not only meets these international standards but also delivers full-system solutions directly to developers in Australia and New Zealand.
For high-performance, project-ready windows & doors, M&C is a trusted and proven partner.
