Advanced multipoint window and door transmission hardware tailored for high-salinity marine environments.
São Tomé and Príncipe, an archipelago nestled in the Gulf of Guinea, experiences a humid tropical climate characterized by constant ocean breezes and high relative humidity. Under these demanding environmental conditions, construction and fenestration materials face extreme oxidation risks. Ordinary zinc-plated steel or low-grade iron hardware rapidly degrades, leading to mechanical failure in multipoint locking systems. For architectural projects in São Tomé, Neves, or Santana, using high-performance Stainless Steel Espag Rods is a critical engineering design standard, not a premium upgrade.
As a leading hardware manufacturer, Jiangsu Jefort Hardware Manufacturing Co., Ltd. addresses these local architectural challenges by providing corrosion-resistant window and door hardware. Standardizing on SS304 and SS316 alloys ensures our espagnolette rods offer structural integrity and smooth operation, preventing premature system failures due to rust.
By focusing on the structural requirements of coastal and luxury developments, Jefort Hardware delivers products featuring customized backsets (from 7.5mm up to 35mm) that integrate with modern European aluminum and UPVC profile systems, establishing us as a strategic supplier for key West African developers.
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.
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.
Equipped with advanced automated stamping and riveting machines, our Jiangsu-based manufacturing facility ensures micron-level precision for every component. Our production capacity reaches a daily volume of 12,000 finished units, enabling us to handle bulk orders from major real estate developments and local architectural distributors in West Africa without compromising quality.

Over the last decade, São Tomé and Príncipe has experienced steady growth in sustainable tourism, infrastructure development, and luxury residential projects. High-end eco-resorts and structural properties on both islands demand premium architectural hardware. Architects and contractors are transitioning from standard ironmongery to high-durability stainless steel variants due to high saline levels and high humidity.
This shift is driven by lifecycle cost management. While cheaper iron or low-grade steel hardware might reduce initial costs, the replacement and labor expenses after failure inside UPVC profiles make them less cost-effective over time. Incorporating Jefort's SUS304 window espag transmission rods ensures long-term operational integrity, reducing maintenance costs for property owners.
Furthermore, local safety regulations for commercial buildings and residential developments are increasingly requiring multi-point locking systems (Eurogroove standard) to enhance break-in protection, further driving the adoption of high-performance espag rods.
At Jefort Hardware, we understand that supply chain reliability is just as critical as product quality. Shipping construction hardware to island nations like São Tomé and Príncipe requires meticulous logistics coordination. We collaborate with international shipping lines to optimize freight routes from major Chinese export hubs (Ningbo/Shanghai) directly to the Port of São Tomé.
To prevent rust during maritime shipping through equatorial corridors, Jefort applies protective packaging to every batch. Products are wrapped in moisture-resistant film, packed in heavy-duty structural cartons, and secured on fumigated pallets. We also offer comprehensive custom clearance documentation, including certificates of origin and detailed material testing certificates, ensuring smooth import procedures at local customs.
We optimize each export shipment with the following safeguards:

Expert answers to common engineering, logistics, and installation queries.
São Tomé and Príncipe's proximity to the Atlantic Ocean exposes building hardware to high levels of chloride (salt spray). Zinc plating offers only temporary protection; once the outer layer breaks down, red rust will lock up the gear mechanism inside. SUS304 contains chromium and nickel, forming a self-healing passivation layer that resists pitting and crevice corrosion under long-term exposure to salt air.
Yes. We support custom backsets from 7.5mm to 35mm. Whether your project utilizes standard 15mm/22mm profiles or specialized local framing systems, our engineering department can customize rods based on your technical drawings. Custom sample production typically takes 3 to 5 business days.
Our window and door hardware undergoes testing for cyclical endurance (25,000 to 50,000 cycles), mechanical load capacity, and neutral salt spray (NSS) testing. We supply material testing reports (MTRs) and CE certification upon request to verify the quality of your shipment.
We work with international logistics providers to manage ocean shipping from China ports (typically Ningbo or Shanghai) to the Port of São Tomé. We offer both Less than Container Load (LCL) for small projects and Full Container Load (FCL) shipping, with all customs documentation prepared to simplify clearance processes.
