Sandblasting Process
Utilizes automatic high-pressure blasting to create a micro-rough surface texture. This dramatically increases mechanical powder adhesion and eliminates micro-imperfections prior to coating.
Material Integrity
Primary 6063-T5 / T6 Aluminum Alloy Engineering
At Foshan Aludex Doors & Windows Co., Ltd., architectural longevity begins with strict metallurgical standards. We utilize 100% primary aluminum ingots as our raw material for profiles, completely avoiding recycled scrap that compromises structural strength.
Our heavy-duty frame profiles are extruded from 6063-T5 / 6063-T6 aluminum alloy, delivering optimal tensile strength and surface finish. Door leaf panels are crafted using 6061-T6 or 5052-H32 aluminum sheets, representing the industry standard for dimensional stability, impact resistance, and corrosion immunity.
Surface Science
Advanced Surface Treatment & Anti-Corrosion Testing
Extremely durable finishes designed to resist extreme weather, high coastal humidity, and prolonged UV exposure.
Acid Washing & Pickling
Multi-stage chemical baths remove residual natural oxide films and organic contaminants. This activates the substrate for flawless, long-term chemical bonding with fluorocarbon and powder coatings.
Salt Spray Chamber Testing
Accelerated corrosion testing simulates harsh coastal environments. Our coatings undergo neutral salt spray testing to verify paint adhesion, edge preservation, and rust-free lifetime performance.
Acoustic & Weather Sealing
Double-Layer EPDM Automotive-Grade Sealing
Foshan Aludex main entrance doors incorporate a continuous double-layer perimeter EPDM rubber sealing system — engineered using the same high-elasticity polymer formulas specified in luxury automotive weatherstripping.
Combined with multi-point locking systems and precise corner joints, our sealed entrance systems deliver exceptional acoustic isolation. When installed correctly according to technical shop drawings, sound attenuation between exterior traffic noise and interior living space can achieve significant noise reductions.
Structural Security
Multi-Chamber Structural Core Architecture
Engineered for structural rigidity and forced-entry deterrence, Foshan Aludex manufactures doors utilizing tailored structural options: non-thermal break profiles, heavy thermal break insulation profiles, and heavy off-axis pivot systems.
The interior core of our armored door leaves features an extruded aluminum alloy framework, structurally reinforced with aerospace-grade aluminum honeycomb panels or high-density flame-retardant polyurethane foam for thermal efficiency and anti-impact strength.
