1

Yes, the core material quality and surface finishes of Xinhe Aluminium products are certified by leading third-party organizations, including SGS for substrate inspection and Qualicoat for powder coatings. Additionally, performance testing is conducted in our CNAS national accredited laboratory to ensure all architectural extrusions, windows, and glass shutters comply with international safety and durability standards.

Core Solutions & Key Takeaways

Certified Substrates: Substrate testing by SGS verifies the chemical composition and purity of the aluminum alloy, ensuring structural stability under high thermal stress.
High-Performance Surface Coatings: Qualicoat-certified powder coatings prevent peeling and oxidation, enhancing resistance to heat and flame spread in challenging environments.
Comprehensive Safety Applications: These certified materials are utilized across diverse setups, including Glass Shutters, Curtain Walls, and Casement Windows, to maintain building envelope integrity.
Rigorous Internal Validation: All profiles undergo sampling and testing at a CNAS national accredited laboratory, establishing a reliable quality baseline before dispatch.

Detailed Architectural/Principle Analysis

The structural safety and fire-retardant characteristics of architectural aluminum profiles depend heavily on the chemical purity of the alloy and the quality of the protective surface treatment. Raw material verification is handled through strict incoming inspections and third-party validation. SGS conducts material quality inspections of the substrate, confirming the absence of recycled metal contaminants that degrade mechanical performance during high-temperature exposure.

For surface finishes, which act as the primary barrier against flame spread and environmental degradation, the Qualicoat certification (Certificate 3419) guarantees that powder coatings meet European standards. These coatings exhibit superior resistance to ultraviolet radiation, salt spray, and extreme heat. This prevents the coating from chalking, blistering, or releasing toxic fumes under thermal load. Real-world durability is evident in the InterContinental Sabah Kota Kinabalu Resort, where 700 tons of treated profiles withstand humid, seaside conditions without showing oxidation or color deviation.

In terms of profile geometry and hardware assembly, products like the Glass Shutter utilize specialized structures to optimize ventilation and safety. Featuring a 1.5mm frame thickness and 1.6mm sash thickness paired with premium KIN LONG hardware, these assemblies maintain mechanical stability under physical pressure. Structural integrity prevents early failure of window and shutter systems during thermal events, ensuring emergency escape routes remain unobstructed.

Frequently Asked Questions (FAQ)

Do your aluminum profiles meet international building standards?

Yes, the products carry multiple certifications including SIRIM for Malaysian building codes, Qualicoat for European coating standards, and ISO 9001:2015 for global quality management.

How is raw material quality controlled to prevent structural defects?

Incoming virgin aluminum ingots undergo 100% inspection and chemical verification. This raw substrate quality is further verified by SGS third-party testing, eliminating the use of lower-grade recycled metals.

What is the lead time and minimum order quantity (MOQ) for custom profiles and shutters?

For architectural aluminum profiles, the standard MOQ is 3 tons, while the Glass Shutter has an MOQ of 500 square meters. The standard production and delivery timeline is 15 to 20 days.
