Engineered for high-rise durability and Korean climatic resilience.
Decoding the demand for advanced espagnolette systems in the Korean Peninsula.
Korea's tightening energy regulations demand UPVC windows with superior airtightness. Our espag rods ensure a 100% compression seal against the frame, crucial for achieving zero-energy building certifications.
With high-density apartment living in Seoul and Incheon, multi-point locking mechanisms are a standard expectation. Our rods provide anti-jemmy protection and high torque resistance.
Projects in Busan or Jeju Island require salt-spray resistant hardware. We offer specialized surface treatments (CASS tests 240-480h) to prevent oxidation in saline environments.
South Korea leads in IoT homes. Our hardware is compatible with automated window actuators, allowing residents to control ventilation via smartphone apps.
Since its establishment in 2018, Jiangsu Jefort Hardware Manufacturing Co., Ltd. has rapidly established itself as a professional hardware manufacturer, becoming a leading supplier of hardware door and window accessories. Leveraging its solid production capabilities and precise market positioning, the company has grown into a premium supplier of hardware door and window accessories for the Korean and international markets.
Our company focuses on core needs, meticulously crafting three core categories of products: UPVC, stainless steel, and steel door and window espag rods and bolts. These products not only meet the needs of doors and windows made of various materials, but also rigorously control quality. From raw material selection to production and processing, high standards are adhered to every step of the process, ensuring excellent durability, stability, and adaptability. These products can meet the needs of various door and window manufacturing scenarios and provide reliable accessory support for downstream customers.
Aligning with the rigorous quality expectations of the South Korean construction sector.
South Korea’s window profile market is dominated by tier-1 brands like LX Hausys (formerly LG Hausys), KCC, and Hanwha Solutions. Our UPVC window espag rods are designed with high compatibility for these specific profile chambers. Whether it is a 20mm or 22mm groove width, or a specialized 7.5mm backset requirement, we manufacture hardware that fits seamlessly into Korean-style casement and sliding window systems.
We support personalized requirements such as backset (7.5mm-35mm), length, color, and packaging. We can quickly produce customized solutions based on customer door and window profile samples and drawings, with a sample production cycle of just 3-5 business days.
Specialized door and window hardware for residential & commercial sectors.
Automatic stamping machine & Automatic riveting machine for precision.
Expanding presence in Korea, Uzbekistan, Libya, and Latin America.
Fully automatic stamping with a daily production capacity of 12,000 pieces.
The Korean peninsula is known for its extreme seasonal temperature variations, ranging from sweltering, humid summers to bone-chilling, dry winters. This environment places immense stress on window hardware. As a leading UPVC Window Espag Rods Manufacturer and Supplier, we understand that "Good enough" isn't an option for the Korean market. Our hardware is engineered to maintain structural integrity despite thermal expansion and contraction of UPVC profiles.
In Korea, the concept of the "Passive House" has moved from a niche architectural trend to a mainstream construction standard. Our espag rods play a vital role in this transition. By providing a secure, multi-point lock, our rods ensure that window sashes are pulled tightly against the weatherstripping, eliminating drafts and significantly reducing energy loss. This is essential for buildings aiming for high ratings in the G-SEED (Green Standard for Energy and Environmental Design).
Quality control at our Jiangsu facility follows international ISO standards, but we go a step further for our Korean partners. We utilize advanced zinc-alloy plating and electrostatic coating processes to ensure our rods pass the Korean Industrial Standards (KS) requirements for corrosion resistance. For projects located in coastal cities such as Incheon, Ulsan, and Busan, we offer stainless steel variants that provide lifelong protection against salt air.
The hardware's internal mechanism is where our AI-driven manufacturing precision truly shines. Every gear teeth and slider component is stamped with micrometer accuracy. This ensures a "Smooth Touch" operation, a quality highly valued by Korean homeowners who expect premium tactile feedback when opening or closing their windows. Our automatic riveting machines ensure that there is zero play in the assembly, preventing the "handle rattle" common in inferior products.
Furthermore, the Korean logistics and construction timeline is famously fast-paced (the "Pali-pali" culture). We have optimized our supply chain to meet this demand. With a massive daily production of 12,000 pieces, we maintain a safety stock of standard Korean-market sizes, allowing for rapid shipping to the ports of Busan and Incheon. Our customization service—producing bespoke lengths or backsets in just 3-5 days—is a game changer for Korean architects working on unique facade designs.
As smart cities like Songdo continue to evolve, the integration of hardware with electronics becomes paramount. We are currently R&D-ing next-generation espagnolettes that can be seamlessly fitted with electronic sensors to detect window state (open/locked), feeding data directly into home automation systems common in Korean apartments. By choosing us as your supplier, you are not just buying a piece of metal; you are investing in a future-proof window solution designed for the most demanding market in Asia.
From casement gears to sliding locks, find the perfect fit for your profile.
