Top-tier components for electrical and structural integrity
Analyzing the shift towards high-performance self-drilling technologies
In the contemporary landscape of global construction and industrial manufacturing, the demand for OEM Self-Drilling Roofing Screws has transitioned from a standard commodity to a critical engineering requirement. As urbanization accelerates across Asia, the Middle East, and South America, the reliance on pre-engineered metal buildings (PEMB) and large-scale solar mounting structures has necessitated fasteners that offer not just connection, but long-term structural integrity.
Zhejiang Jifeilong Instrument Technology Co., LTD., with its deep-rooted history since 1999, stands at the nexus of this industrial evolution. By integrating advanced metallurgical practices with automated precision, we address the core pain points of the industry: corrosion resistance, pull-out strength, and drilling speed. Our role as a leading OEM roofing screw factory involves more than manufacturing; it is about providing the "precision foundations" for global infrastructure.
Self-drilling screws are defined by their ability to drill their own pilot hole, tap a thread, and fasten—all in a single motion. However, the engineering behind this involves complex variables that Jifeilong has mastered over decades.
We utilize varying point styles (from #1 to #5) depending on the material thickness. A #5 point can penetrate up to 12.5mm of heavy-gauge structural steel without pre-drilling, a feat of high-torque engineering.
For roofing, corrosion is the enemy. We offer multi-layer coatings including Ruspert (1000-2500 hours salt spray test) and Dacromet, providing superior galvanic protection compared to standard zinc plating.
Our roofing screws feature EPDM (Ethylene Propylene Diene Monomer) bonded washers. Unlike standard rubber, EPDM withstands extreme UV exposure and thermal cycling without cracking, ensuring a leak-proof seal for decades.
The industrial fastening landscape is currently grappling with two major trends: Sustainability and Smart Installation. As an OEM supplier, Jifeilong is pioneering the use of higher-grade recycled steel without compromising the structural tensile strength required for hurricane-prone regions or seismic zones.
Established in 1999, Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) is located at the strategic Oujiang Port. Our facility integrates production, processing, and high-precision grinding departments. We are not just a manufacturer; we are a partner in the global supply chain for electrical switches, shafts, and industrial hardware.
Core Philosophies:
Our ISO9001 certification and strict adherence to national and international quality standards ensure that every batch of self-drilling screws meets the rigorous demands of the global market.
For an OEM self-drilling roofing screws supplier, compliance is the ultimate form of reliability. Jifeilong understands the specific requirements of different regional markets:
Focus on pull-over strength, shear resistance, and compliance with ASTM C1513 for cold-formed steel framing.
Adherence to Eurocode 5 for timber structures and EN 1090 for steel, emphasizing environmental impact and material traceability.
The strictest standards for atmospheric corrosion, requiring Class 3 and Class 4 coatings for coastal industrial environments.
From micro-electronics to heavy structural engineering
Pins and shafts for molded case circuit breakers (MCCB), ensuring electrical safety and mechanical durability.
High-tensile rivets and screws for power equipment housing and low-voltage electrical cabinet assembly.
Custom connectors for EV charging piles, requiring high conductivity and resistance to outdoor environmental stressors.
Jifeilong is investing in the "Next-Gen Fastener" initiative, focusing on three key pillars:
Answering common technical queries from engineers and procurement officers
Reliable components ready for international distribution
