Our leading structural aluminum folding systems custom-engineered for modern residential, commercial, and mixed-use structures across the Seoul Metropolitan Area.
Seoul’s extreme temperature swings—ranging from below -10°C in Gyeonggi winters to over 35°C during the humid summer monsoons—demand window systems of superior build quality. Over the last decade, the Seoul Metropolitan Government has heavily tightened building energy efficiency standards. Residential and commercial developments in areas such as Gangnam, Mapo, and Seongsu-dong are shifting away from traditional fixed panels toward structural folding systems that maximize ventilation, natural light, and space efficiency.
The local architectural fabric is highly competitive. Trendy commercial districts like Hongdae, Itaewon, and Sinsa-dong rely on wide-opening pass-through windows to link interior cafe layouts with outdoor street scenes. Our structural aluminum folding systems deliver the mandatory thermal insulation values (meeting Korea's Grade 1 and 2 window regulations) through heavy-duty polyamide thermal breaks and gas-filled IGUs (Insulated Glass Units).
Moreover, high-density residential developments (Apts) in districts like Songpa and Seocho require exceptional wind load performance and resistance to water infiltration. Our systems are engineered to withstand typhoon-level wind forces and prevent leakage during torrential rains, providing long-term reliability for local builders and contractors.
Every profile configuration complies with South Korea’s rigorous Energy Efficiency Labeling and Standards Program, utilizing multi-chambered profiles and low-E coatings.
Equipped with integrated, high-durability sliding and folding invisible screens to block seasonal yellow dust (Hwang-sa) while maintaining airflow.
Bridging high-volume Chinese precision manufacturing with global architectural trends to meet the needs of the Seoul construction sector.
The international market for architectural aluminum folding windows has experienced rapid expansion, driven by green building standards (such as LEED, BREEAM, and Korea's G-SEED). Commercial architects no longer see exterior glazing simply as a barrier; they view it as an active component of a building’s thermal envelope. As a leading manufacturer based in Foshan, China—the global center for architectural aluminum extrusion—Foshan ORM Windows Co., Ltd. uses state-of-the-art technology to manufacture systems that meet AS2047, CE, and ASTM standards.
Foshan's integrated supply chain allows for high-precision profile extrusion, advanced surface finishing (including PVDF fluorocarbon coatings and anodized architectural finishes), and automated double/triple glazing assembly. For importers and developers in the Seoul Capital Area, this translates to stable pricing, certified quality controls, and reliable shipping timelines from Gwangdong to Incheon or Busan Port. By working directly with a manufacturer, local clients bypass middleman markup while receiving customized structural options tailored to high-density Korean urban sites.

Engineered solutions for residential complexes, commercial zones, and urban villas demanding robust profiles and secure lock systems.
Our R&D team continuously refines system details to improve thermal efficiency, acoustic insulation, and security.
We use PA66 GF25 (25% glass fiber reinforced polyamide) thermal break strips to separate the inner and outer aluminum frames. This effectively blocks thermal transfer, preventing interior condensation during sub-zero Seoul winters.
Our triple and double glazing options include low-E coated glass filled with 90%+ Argon gas. This keeps solar heat out during summer while retaining internal heat during winter, supporting energy-efficient building operations.
Equipped with heavy-duty multi-point locking systems along the frame profile. This ensures tight perimeter seals to improve acoustic performance, keep wind out, and provide reliable home security.
Seoul is a vibrant, dense metropolis. Noise pollution from primary arteries like Olympic-daero, Gangnam-daero, and transit hubs can impact residential comfort. Our high-performance folding window frames feature built-in acoustic damping cavities. By combining asymmetric laminated glass panes (e.g., 6mm + 12Ar + 5mm) with double-density EPDM gaskets, our systems reduce noise levels by up to 45 decibels, creating peaceful indoor spaces even in busy urban areas.
Airborne particulate matter, industrial exhaust, and seasonal moisture can cause premature wear on standard metal window frames. We treat our raw 6063 aluminum alloy profiles with a multi-stage chemical pretreatment, followed by electrostatic powder coating or marine-grade anodizing. This guarantees that our frames retain their color, resist UV fading, and prevent surface corrosion over decades of service.
Established in 2011, Foshan ORM Windows Co., Ltd. is a specialized manufacturer of high-performance aluminum window and door systems. Located in Foshan, Guangdong, China—the country's leading center for architectural aluminum production—our facility covers more than 20,000 square meters. Backed by 280+ skilled employees and an in-house engineering team, we focus on producing reliable, energy-efficient, and visually appealing window systems for global residential and commercial projects.
Our product range includes casement windows, sliding panels, tilt-and-turn designs, heavy-duty thermal break structures, and custom bifold and vertical fold systems. We integrate quality control measures at every stage, from profile cutting and corner crimping to automated glass glazing and hardware fitting. As an experienced OEM/ODM provider, we work closely with developers and distributors to meet specific project guidelines, performance criteria, and aesthetic preferences.
Equipped with CNC double-head cutting saws, heavy-duty corner-punching machines, and automated double-glazing lines, our facility maintains tight production tolerances. This allows us to ensure that our folding windows operate smoothly and fit precisely upon delivery.










Expert technical answers regarding structural wind load, thermal values, shipping logistics, and installation in the Seoul Capital Area.
Yes. South Korea's building code classifies window thermal performance from Grade 1 (highest) to Grade 5. Our high-spec double and triple-glazed thermal break folding systems are designed to satisfy Grade 2 and Grade 1 specifications, which are frequently required for new residential and commercial structures in central Seoul and Gyeonggi Province.
Generally, the manufacturing cycle takes 25 to 35 days, depending on custom profile requirements, finish selections, and order volume. Sea freight transit from Guangzhou/Shenzhen port to Incheon or Busan Port takes 3 to 5 days, followed by 2 to 3 days for customs clearance and inland delivery to your Seoul construction site.
Our window profiles are fabricated from structural-grade 6063-T5/T6 aluminum alloy. We incorporate internal drainage channels, stepped frame paths, and continuous EPDM seals to prevent water backup. Our systems are certified for wind pressure resistance up to 4.5 kPa, making them suitable for high-density, high-rise urban developments.
We offer customization across frame profiles (60mm to 120mm depth), finishes (powder coating in RAL colors, fluorocarbon PVDF, wood grain sublimations), and glazing (laminated, tempered, triple-pane Low-E, smart PDLC privacy glass). We can also adapt specific European or Korean hardware brands (such as G-U, Roto, or local Korean multi-lock configurations) according to project specifications.
