Engineered to deliver elite thermal insulation, typhoon-grade structural resistance, and exceptional marine-grade longevity.
Kiribati's geographical profile—spanning 33 atolls with communities concentrated in South Tarawa and Kiritimati—presents one of the world's most aggressive environments for building materials. High ambient humidity, constant salt spray, and extreme UV exposure accelerate the structural degradation of typical metal framework. Windows are particularly vulnerable to corrosion, water penetration, and thermal stress.
For large-scale public infrastructure, resort hospitality developments, and residential programs across the Gilbert, Line, and Phoenix Islands, standard grade frames fail within years. To secure durability, architects and contractors demand highly customized awning aluminum windows engineered with structural thermal-break profiles and corrosion-resistant finishes. Awning designs are especially favored as they offer optimal ventilation while deflecting rain during the sudden, heavy downpours typical of Kiribati's equatorial zone.
"Marine-grade powder coating (AAMA 2605 standard) and specialized weather sealing are mandatory requirements for window fixtures on low-lying coral atolls to combat coastal degradation."
At Shandong Envi Doors and Windows Co., Ltd., we customize architectural profiles to resist both the corrosive maritime boundary layers and the extreme pressure fluctuations of tropical weather systems.
Integrating advanced metallurgy, precision extrusion, and certified thermal performance.
Shandong Envi Doors and Windows Co., Ltd., established in 2014, is a premier, large-scale comprehensive aluminum profile enterprise engaged in development, design, and production. Originating from our group's foundational operations in 1993, we have dedicated decades of research and investment to architectural grade alloys. Today, our facilities cover an expansive area of 100,000 square meters, housing highly automated aluminum extrusion lines designed to produce top-tier architectural, decorative, and industrial profiles. With an annual designed output capacity of approximately 50,000 tons and a market value of 1 billion yuan, we scale to meet large-volume infrastructure demands globally.
Our industrial plant utilizes highly automated systems ranging from 600 tons to 2,500 tons extrusion presses, two dedicated anodizing lines, two electrophoretic coating lines, and a high-throughput color powder spraying profile production line. This is complemented by specialized thermal break assembly lines, glue injection lines, simulated wood grain treatments, and advanced deep-processing machinery inside our specialized production workshops.
Over the past decade, we have successfully supplied and supported more than 1,500 projects across 100 countries and regions. Every window assembly meets international quality standards, ensuring long-term thermal efficiency and mechanical reliability.

Our profiles utilize high-tensile 6063-T5 and 6063-T6 aluminum alloys. This combination delivers optimal structural elasticity, allowing windows to deflect and recover from the intense windward pressures common to Tarawa's open coastlines. Our wall thickness designs meet and exceed Australia's AS2047 standard for window structural deflection performance.
Kiribati's location near the equator subjects buildings to continuous solar radiation. By embedding polyamide thermal barrier strips (PA66-GF25), we decouple the outer aluminum frame from the inner room structure. This effectively blocks direct heat conduction, lowering HVAC energy loads and preventing condensation inside air-conditioned spaces.
Standard finishes pit and bubble in saline air. Shandong Envi applies high-grade PVDF coatings utilizing fluoropolymer resins that resist UV degradation, fading, and chemical breakdown. For architectural programs in Kiribati, we customize anodized coatings up to class AA25 (25 microns thickness), preventing oxidation from marine atmospheres.

To combat marine boundary corrosion, we employ two primary solutions. First, Fluorocarbon (PVDF) coatings (with at least 70% Kynar 500 resin) meeting the rigorous AAMA 2605 specifications. This finish is resistant to chemical attack and chalking. Second, Anodizing with a film thickness of 25 microns (Class 1 / AA25). This electrochemical conversion coat turns the aluminum surface into an ultra-hard, integrated aluminum oxide layer, preventing oxidation and pitting caused by sodium chloride crystals.
Kiribati experiences high year-round solar gain. Standard aluminum frame windows act as thermal bridges, heating the building interior and forcing HVAC systems to work harder. Our windows use Polyamide thermal barriers (PA66-GF25 reinforced with fiberglass) to isolate the exterior frame from the interior. This layout minimizes convective and conductive thermal transfer. Combining this frame with double or triple-glazed Low-E argon-filled units yields a low Solar Heat Gain Coefficient (SHGC) and low U-Factor, reducing interior cooling costs.
Yes. Our product lines are manufactured and tested to meet structural wind pressure requirements up to AS2047 / AS1288 (Australian Standards) and NFRC ratings. Our heavy-duty window designs feature double-action EPDM compression seals and multipoint locking hardware. This keeps the window closed tight against heavy winds and prevents water penetration even at wind pressures exceeding 4500 Pa.
To prevent damage during sea transit and port handling at Betio, Tarawa, or London, Kiritimati, we package our window systems in fully enclosed, IPPC-certified fumigated wooden crates. Metal components are wrapped in protective polyethylene films, and moisture-absorbing silica gel packs are distributed within the packages to prevent condensation and oxidation. We work with leading international shipping lines to coordinate safe delivery.
