In the contemporary landscape of industrial construction and metal roofing, the integrity of a structure often depends on the smallest components. Custom Self Sealing Roof Screws have evolved from simple mechanical fasteners into sophisticated sealing systems designed to combat hydrostatic pressure, thermal expansion, and electrochemical corrosion. As a leading manufacturer, Zhejiang Jifeilong Instrument Technology Co., LTD. applies its decades of expertise in high-precision electrical components to the fastener industry, ensuring that every screw provides an airtight, watertight, and durable bond.
The global demand for high-performance roofing screws is surging, driven by the rise of Pre-Engineered Buildings (PEB) and the integration of Solar Photovoltaic (PV) systems on industrial roofs. Manufacturers are now required to meet stringent international standards such as FM Global and DIN EN 1090, ensuring performance in extreme weather conditions from the humid tropics of Southeast Asia to the corrosive coastal regions of the North Sea.
Beyond simple attachment, modern self-sealing screws serve as a barrier against environmental degradation. By utilizing EPDM (Ethylene Propylene Diene Monomer) bonded washers and advanced coatings like JS1000 or Dacromet, these fasteners provide a multi-layered defense. This is critical in the chemical processing and cold storage industries, where internal and external temperature differentials create significant condensation risks.
Leveraging our background in electrical switch components and shafts, we bring a "micron-level" precision mindset to fastener manufacturing. Unlike standard mass-produced screws, our custom solutions feature optimized thread geometries that reduce installation torque while maximizing pull-out strength, a critical factor for high-wind-zone (Hurricane) compliance.
Our facility is ISO9001:2015 certified, implementing Total Quality Management (TQM). We provide comprehensive documentation, including:
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Located at the Oujiang Port in Wenzhou City, we operate a vertically integrated manufacturing facility. We mainly engage in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components. Our products are widely used in home appliances, solenoid valves, electronics, automobiles, and filtration equipment.
By implementing strict quality control from raw material procurement to finished product delivery, the company has passed the ISO9001 certification. Through technological and equipment transformation, we have achieved fully automated production capacity, winning the trust of over 100 enterprise customers in China and expanding rapidly into the international market.
Operate With Integrity: Achieving multi-party win-win through transparent business practices.
Quality First: Adhering to the tenet of "seeking truth from facts."
Our technical roadmap includes the development of Smart Fasteners with integrated sensors for structural health monitoring and the adoption of bio-based coatings to align with global ESG (Environmental, Social, and Governance) targets. We strive to become a high-quality global supplier of precision components for the next generation of industry.
