High-performance exterior doors engineered specifically to resist extreme coastal humidity, high-salinity air, and typhoon-level tropical wind pressures.
Teaoraereke, as one of the key urban and administrative hubs in South Tarawa, Kiribati, experiences a distinct equatorial marine climate. Characterized by high year-round relative humidity (often exceeding 80%), intensive UV radiation exposure, constant salt-laden oceanic aerosol, and periodic severe storm surges, the building envelope demands non-compromised material selection.
Conventional timber doors suffer from swelling, fungal decay, and termite degradation within 24 to 36 months of deployment. Low-grade carbon steel doors experience severe electrochemical oxidation (rusting) at accelerated rates due to airborne chloride ions. Consequently, modern infrastructure projects, government buildings, coastal residences, and commercial establishments serving Teaoraereke have systematically shifted toward high-grade anodized and fluorocarbon (PVDF) coated 6063-T5 aluminum entrance systems.
By bypassing trading intermediaries and sourcing direct from our 180,000 m² Foshan facility, contractors and government procurement officers in Kiribati gain structural engineering superiority at optimized factory-direct economics.
We utilize high-density 6063-T5 and 6061-T6 aluminum alloys with minimum wall thicknesses ranging from 2.0mm to 3.0mm for entry doors. This provides unmatched structural resistance against door sag, frame deformation, and hurricane impacts.
Our surface finishing line incorporates triple-coat PVDF (Fluorocarbon) and Class 25 (25 micron) anodizing processes. Tested under ASTM B117 salt spray chambers for over 3000 hours without chalking, blistering, or color fading.
Direct container loading plans managed from Foshan to South Tarawa (via key transit hubs like Suva or Sydney). Every door leaf is individually vacuum-sealed with desiccant, foam corner guards, and fully enclosed export plywood crates.

From residential luxury villas to high-security public buildings, our entry doors meet specific architectural codes and functional requirements.
Public facilities in South Tarawa demand heavy-duty entrance systems capable of enduring continuous pedestrian traffic while maintaining security. Our stainless steel reinforced aluminum frame pivot doors with multi-point automated locking mechanisms provide maximum structural integrity, fire-rated option profiles, and electronic access control integration.
High-end tourist accommodation facilities require expansive oceanfront views without compromising storm safety. DERCHI double-glazed, hurricane-impact aluminum bi-fold and sliding door series offer panoramic sightlines, high acoustic damping (up to 38dB noise reduction), and effortless sliding functionality even under intense marine wind loads.
Modern private residences in Teaoraereke demand sophisticated architectural statements. Our oversized grand entry pivot doors (up to 2000mm x 4000mm leaf size) utilize German-engineered heavy-duty floor pivots rated for 500kg loads, integrated smart biometric lock handles, and cast aluminum decorative infill panels.
For logistical storage facilities and back-of-house utility areas near Betio Port, DERCHI provides SUS316 stainless steel frame security entry doors filled with sound-deadening and fire-retardant mineral rock wool, offering high anti-prying security and maximum resistance to airborne sea fog.
Every door system manufactured for Teaoraereke undergoes rigorous factory inspection before container loading.
Architectural drawing verification, profile section detail generation, structural wind load analysis, and hardware specification approval.
Computer-controlled cutting and corner crimping held within ±0.5mm tolerances to guarantee absolute frame squareness and air-tight joint seals.
Sample batch testing for water penetration, high-pressure air infiltration, and physical cyclic operation strength up to 100,000 cycles.
Protective PE film wrapping, EPE foam edge protectors, moisture-absorbing desiccants, and solid fumigation-free wooden crates.
Everything you need to know about custom ordering, shipping logistics, wind-load compliance, and ocean freight to Kiribati.
In Teaoraereke’s high-humidity marine environment, natural wood doors rapidly warp, crack, swell, and attract termites due to constant exposure to tropical moisture and airborne salt. Marine-grade 6063-T5 aluminum entrance doors treated with PVDF fluorocarbon coatings provide absolute immunity to rot, termite infestation, and rust, maintaining structural alignment and operational smoothness for decades with minimal maintenance.
Standard manufacturing time is 25 to 35 days following CAD shop drawing approval and deposit receipt. Shipping from our Foshan factory to Betio Port in South Tarawa is routed via international vessel connections (typically transshipping through Suva, Fiji or major Australian ports). Total transit time is generally 30 to 45 days. We provide complete sea-freight documentation, customs clearance papers, and container loading schedules.
Yes. Our hurricane-proof series are engineered and tested in accordance with AS2047 (Australian Standard for Windows and Doors) up to the N6 structural classification, capable of withstanding extreme wind pressures up to 4500 Pa. Profiles feature heavy internal aluminum webbing, multi-point lock systems, and laminated impact-resistant glass (such as 6mm Tempered + 1.52PVB + 6mm Tempered) designed to absorb high-velocity debris impact.
For all coastal exports destined for Pacific island environments, we explicitly specify Grade 304 or Grade 316 stainless steel hardware components, heavy-duty anodized pivot hinges, and electroplated lock cylinders. Standard steel components are completely excluded to prevent galvanic corrosion and hardware seizure under saline air conditions.
Absolutely. Every entry door is 100% custom fabricated to your exact rough opening dimensions. Our in-house structural engineering team provides complimentary 2D CAD shop drawings, elevation details, and 3D BIM models for architect review and approval before production commences.
For equatorial locations like Kiribati, we strongly recommend double-glazed insulated glass units (IGUs) incorporating Low-E (Low Emissivity) coatings, argon gas filling, and warm-edge spacers (e.g., 6mm Low-E Toughened + 12Ar + 6mm Toughened Clear). This setup blocks up to 78% of solar infrared heat transmission while maintaining crystal-clear interior daylighting.
We maintain flexible ordering terms. We accept single-unit orders for high-end residential luxury entry pivot doors or custom villa samples, as well as full container loads (20GP / 40HQ) for commercial developments, resorts, and government housing projects.
Yes. Every shipped door kit includes numbered structural components corresponding to site schedules, detailed English installation manuals, step-by-step anchoring diagrams, and torque specs. Furthermore, our technical engineers provide remote video consultation to assist site managers during initial opening installations.
Select from thermally broken aluminum, hurricane-impact glass bi-fold, smart security entrance, and cast aluminum door configurations.
