Precision OEM Aluminium Framed Door Portfolios
Direct from our 180,000 m² Foshan fabrication hub to Port of Manila (MICP / South Harbor). Each profile is manufactured from prime 6063-T5/T6 thermal-break billet with marine-grade surface finishes tested against tropical humidity and cyclonic pressures.
Technical Adaptations for Philippine Environmental Stressors
Metro Manila's architectural landscape faces extreme environmental challenges: super typhoons with wind gusts exceeding 250 km/h, intense UV degradation, severe tropical moisture (Habagat monsoons), and corrosive coastal air along Manila Bay. Standard commercial doors quickly fail under these relentless forces.
NSCP Zone 1 Structural Wind Load Resistance
Under the National Structural Code of the Philippines (NSCP 2015), Metro Manila falls within wind zone classifications that require exterior glazing and framing assemblies to withstand elevated basic wind speeds (V = 250 to 300 km/h). In high-rise corridors like Bonifacio Global City (BGC) and Makati, negative wind suction on corner building envelopes places catastrophic shear stress on door stiles.
Our OEM aluminium framed doors are engineered with heavy-wall 6063-T6 extrusions with reinforced corner cleating and internal steel stiffeners. Every system meets structural deflection criteria (L/175 or L/240) tested up to an N6 rating (equivalent to 4500 Pa ultimate wind pressure), preventing glass pop-out and frame buckling.
- Ultimate Wind Pressure: Engineered to withstand peak design loads exceeding 4.5 kPa.
- Deflection Integrity: High-moment of inertia (Ix/Iy) mullions prevent frame warp on tall spans.
- Laminated Impact Glass: Optional SentryGlas® interlayers to resist airborne flying debris.
Water Penetration & Salt Spray Anti-Corrosion (Qualicoat Class 2)
Tropical cloudbursts during the southwest monsoon regularly inundate building facades. Standard sliding and folding tracks often fail, overflowing internal floorboards. We integrate pressure-equalized drainage systems, stepped sill geometries, and dual-compound vulcanized EPDM continuous gaskets to ensure zero static water leakage at test pressures over 450 Pa.
For waterfront structures along Roxas Boulevard, Pasay Bay Area, and Paranaque, airborne chlorides cause rapid pit corrosion on low-grade anodized aluminium. Our OEM fabrication uses Qualicoat Class 2 architectural powders or 3-coat fluorocarbon PVDF finishes (70% Kynar 500 resin), exceeding 3,000 hours in neutral salt spray testing (ASTM B117).
- Stepped Sills with Concealed Weep-Holes: High-capacity self-draining channels stop water backup.
- Marine 316 Hardware: All rollers, multipoint gearboxes, and pivot axes cast from SUS316.
- Thermal Barrier (PA66 GF25): German-engineered thermal breaks mitigate thermal bridging.
| Performance Parameter | Standard Local Commercial Grade | Our Custom OEM Export Specification | Operational Benefit in Metro Manila |
|---|---|---|---|
| Aluminium Alloy & Billet | Recycled / secondary extrusions (0.8 - 1.2mm) | Prime 6063-T5/T6 Virgin Ingot (2.0 - 3.5mm wall) | Eliminates structural flexing; supports oversized glass spans. |
| Wind Pressure Rating | 1,200 - 1,800 Pa (basic residential) | Up to 4,500 Pa (AS2047 N6 / NSCP Zone 1 certified) | Guarantees safety in Super Typhoons and high-rise shear zones. |
| Surface Protection | Basic commercial powder coating (<40µm) | Qualicoat Class 2 or PVDF 3-coat (60-80µm fluorocarbon) | 25+ year color stability against UV and Manila Bay marine salinity. |
| Hardware & Fasteners | Carbon steel or 201 grade stainless steel | High-tensile SUS304 / Marine SUS316 stainless steel | Zero rust seizure; smooth operation in 90%+ relative humidity. |
| Glass Specification | Single 6mm annealed or non-certified float | Double-glazed Low-E + Argon (e.g., 6mm+12A+6mm laminated) | Cuts indoor cooling consumption by up to 35% across tropical summers. |
Tailored Deployment Across Metro Manila's Key Sectors

Emerging Architectural Fenestration Trends in Metro Manila
The Philippine building construction sector is experiencing rapid transformation driven by sustainable building mandates, high-density urban living, and modern tropical architecture.
1. BERDE & LEED Green Building Mandates
Developers are prioritizing carbon reduction and energy conservation. Our double-glazed Low-E argon-filled units deliver low Solar Heat Gain Coefficients (SHGC < 0.32) and optimal U-values, enabling developers to earn maximum points under the Philippine Green Building Code (BERDE) and USGBC LEED ratings.
2. Ultra-Slim Sightlines & Oversized Floor-to-Ceiling Spans
Modern Filipino architects favor minimalist profiles that blur the line between indoor living areas and lush outdoor lanais. High-tensile aluminium profiles allow panel heights exceeding 3.5 meters with narrow visible frames without compromising structural rigidity against typhoon wind loads.
3. Smart Access & Biometric Security Integration
Security is paramount in both luxury gated subdivisions and urban condominiums. Our doors feature integrated cable raceways and CNC mortises compatible with high-end digital locks, facial recognition sensors, and automated building management systems (BMS).
4. Direct OEM Supply Chains Over Importer Markups
General contractors and quantity surveyors across Manila are shifting from local middlemen to direct manufacturer partnerships. Factory-direct procurement delivers custom sizing, unified warranties, certified shop drawings, and 20% to 35% material budget savings.
5. Enhanced Acoustic Isolation for Transit Corridors
With ongoing infrastructure expansions such as the Metro Manila Subway and Skyway extensions, demand for STC 38+ acoustic glazing and multi-chambered thermally broken aluminium doors has surged among residential developers in high-density zones.
6. Marine-Grade Stainless Steel & Cast Hybrid Systems
In high-salinity coastal microclimates, composite assemblies combining heavy cast aluminium artistic panels with 316 stainless inner cores are gaining traction as high-prestige, zero-maintenance main entrance gates.
