Engineered specifically to balance monumental scale, airtight weatherproofing, and dynamic wind resistance against western Pacific maritime squalls and tropical heat.
An entrance door in the Philippine archipelago faces climatic stressors unlike any standard continental environment: persistent relative humidity averaging 75-88%, high ultraviolet degradation index, C4/C5 marine salinity, and severe cyclonic gust loading.
Under the National Structural Code of the Philippines (NSCP 2015 Chapter 2 - Minimum Design Loads), structures along coastal belts (Zone 1) must withstand basic wind speeds exceeding 250 to 300 km/h. Standard residential doors experience immediate deflection, mullion rupture, or water penetration.
Our heavy-duty double front doors feature 6063-T6 and 6061-T6 architectural grade aluminum extrusions with reinforced profile wall thicknesses of 2.5mm to 3.5mm, paired with internal zinc-chromate steel stiffeners at pivotal structural nodes.
Philippine waterfront developments in Batangas, Palawan, and Cebu suffer accelerated pitting and galvanization failure from airborne chlorides. Ordinary anodized profiles deteriorate within 24 months, blistering perimeter seals.
We deploy Qualicoat Class 2 certified powder coating and 3-coat fluoropolymer (PVDF) electro-deposition finishes exceeding 3,000 hours of continuous ASTM B117 neutral salt spray testing, maintaining gloss retention over 85% despite relentless tropical sun and sea spray exposure.
Typhoons such as Super Typhoon Odette and Goni demonstrated that water intrusion primarily occurs at threshold joints and inter-leaf junctions when air pressure differentials suck rain uphill against gravity sills.
Our double door suites integrate multi-tiered automotive-grade co-extruded EPDM weather-stripping, stepped water deflector sills with concealed one-way drainage weep holes, and multi-point shoot-bolt locking hardware providing positive mechanical compression along all four perimeter margins.
Direct exposure to Philippine construction realities drives our product engineering. At WORLDBEX (The Philippine World Building and Construction Exposition), our structural entrance systems received unanimous acclaim from leading UAP (United Architects of the Philippines) fellows, real estate developers, and general contractors from Metro Manila, Metro Cebu, and Davao.
Unlike middleman trading companies, we are a direct manufacturer operating a modern 180,000㎡ industrial complex in Foshan, China—the world capital of high-end architectural fenestration. By eliminating intermediaries, we grant Philippine architectural practices direct access to bespoke fabrication, factory-level price advantages, and mill-certified structural traceability.
From private master-planned enclaves in Taguig to typhoon-exposed beachfront properties in the Visayas, each entrance represents a calibrated balance between structural defense and luxury visual impact.

How structural engineering, sustainability mandates, and minimalist aesthetics are reshaping architectural master-specifications across Luzon, Visayas, and Mindanao.
Philippine developers are rapidly moving past standard mechanical keys. The demand is centered on concealed electric mortise locks compatible with Tuya, Control4, Apple HomeKit, and biometric 3D facial recognition that can operate through backup power capacitors during grid brownouts.
Oversized double pivot door assemblies reaching 3.0m wide by 3.8m high have superseded traditional multi-panel entries in high-end gated subdivisions. These doors require floor-concealed hydraulic self-closing mechanisms capable of smooth 360° wind dampening.
With the adoption of the Philippine Green Building Code and BERDE (Building for Ecologically Responsive Design Excellence), developers must lower overall Solar Heat Gain Coefficients (SHGC). Thermally broken aluminum double doors directly optimize overall envelope compliance.
Contemporary tropical residential styles in Tagaytay and Nuvali favor razor-thin sightlines combined with textural finishes such as cast aluminum woodgrain textures, fluted glass infills, and invisible sub-frame installations with flush plaster lines.
Essential operational answers for architects, quantity surveyors, and project developers importing directly from Foshan to Manila, Cebu, or Batangas ports.
We offer both FOB China port terms and full CIF Manila (MICT / South Harbor), CIF Batangas Port, or CIF Cebu International Port. All cargo is crated in fumigated export-grade solid wood cases with internal waterproof poly-wrap and desiccants to withstand high tropical moisture during ocean transit (average 7 to 10 days sailing from Shekou/Nansha to Manila). We provide complete HS Code documentation (7610.10) for seamless Bureau of Customs (BOC) processing.
Every custom double front door order is engineered through a rigorous 3-step drawing sign-off process. Our technical CAD department generates detailed 1:1 shop drawings showing overall frame width/height, rough opening clearances, floor sill datum lines (finished floor levels), and sub-frame fixing lugs. Fabrication commences only after the client's project architect or general contractor signs and stamps the CAD submittal.
Yes. Every export crate contains a complete visual installation manual, numbered assembly schematics, anchoring brackets, and pre-machined hardware cutouts. Critical components (such as pivot gearings and multi-point shoot bolts) are factory pre-installed and aligned prior to dispatch. Furthermore, our bilingual structural engineers provide real-time WhatsApp or Zoom technical support during on-site framing and glazing stages.
Unlike standard sliding patio sills that rely on gravity drainage alone, our hinged and pivot double doors utilize an engineered stepped threshold system with high-compression EPDM bottom gaskets and an integrated reverse-water deflector baffle. This prevents dynamic wind pressures up to 600 Pa from forcing pooling water backward underneath the door leaf into interior hardwood or marble floors.
Standard production for custom architectural aluminum double front doors is approximately 25 to 35 business days following final CAD approval. Direct ocean freight from South China ports (Shenzhen/Guangzhou) to Manila International Container Terminal takes only 5 to 7 days, making the total turnaround faster and significantly more reliable than sourcing from European manufacturers.
Yes. We supply comprehensive structural calculation sheets, alloy mill certificates, and international test reports (including CE, ISO 9001, AS 2047 N6 wind/water tests, and UL ratings) that can be directly submitted to local government Building Officials (OBO) throughout Metro Manila, Tagaytay, Cebu, and other Philippine regulatory jurisdictions.
Operating as Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI), our production base in Shishan Town, Foshan, represents the apex of modern fenestration engineering. With more than 600 dedicated production staff, automated CNC four-axis profile machining centers, robotic corner-crimping cells, and integrated IGU tempering production lines, we guarantee micron-level dimensional precision.
Every single double front door undergoes 100% pre-assembly inspection before crating: squareness verification, mechanical swing torque calibration, gasket compression sealing audits, and latch tolerance checks. When your container arrives at the job site in Makati or Cebu, the components assemble effortlessly without on-site re-machining.
Whether you are engineering a private coastal villa in Batangas, specifying an ultra-luxury residence in Forbes Park, or managing a high-density mixed-use development in BGC, our engineering desk will prepare structural wind-load evaluations and complimentary CAD shop drawings within 24 hours.
