Engineered for Precision, Protected by Performance
In the modern industrial landscape, corrosion remains a multi-billion dollar challenge, affecting everything from automotive logistics to aerospace precision components. Rust preventive oils have evolved from simple barrier coatings to sophisticated chemical formulations that offer multi-phase protection. As a leading supplier in China, Shandong Longhai Lubrication Technology understands that the "Search Intent" of modern procurement officers has shifted from merely seeking "oil" to demanding "sustainable corrosion mitigation systems."
Globally, the demand for rust preventive solutions is surging in the Asia-Pacific region, driven by the expansion of EV manufacturing and high-speed rail networks. These sectors require oils that are not only effective but also compatible with advanced alloys and polymer-integrated systems. Our R&D focuses on the Information Gain of our products—providing data-backed results on salt spray resistance, film thickness, and ease of removal, ensuring our clients stay ahead of the competition.

Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech titan in the lubrication sector. With over 15 years of deep industry immersion, we have constructed a vertically integrated industrial chain that bridges advanced R&D with precision manufacturing.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is exemplified by our dual-brand strategy: our proprietary "Century Longhai" and our strategic collaboration with the prestigious British "A Ba" series. Our portfolio is exhaustive, covering diesel and gasoline engine oils, hydraulic fluids, and specialized rust preventives insured by PICC (China People's Insurance Company), guaranteeing peace of mind for global distributors.
Leveraging molecular-level coatings that provide 300% better coverage than traditional solvent-based oils, reducing consumption by 40%.
Transitioning to renewable ester bases to meet stringent global VOC regulations and ESG goals for our international partners.
Integrating sensors and predictive modeling to create "Smart Oils" that adapt their viscosity and protective layers based on environmental humidity and temperature.
Tailored protection for the world's most demanding environments
Specialized VCI (Volatile Corrosion Inhibitor) oils for cross-continental sea freight, resisting salt-spray and extreme humidity for up to 24 months of storage.
Ultra-thin rust preventive films that do not interfere with subsequent welding or painting processes, streamlining the assembly line efficiency.
Dewatering rust preventives that instantly displace moisture from micro-crevices in CNC machinery and high-carbon steel molds.
Longhai Technology operates 131 acres of intelligent production space. Our automated filling lines increase speed by 35% while maintaining a precision of 1‰-2‰. This ensures that every drop of rust preventive oil meets the rigorous standards our global clients expect.
Strategic R&D investment (5% of revenue) fuels our proprietary formulas.
Equipped with laboratories that simulate extreme climates and stress conditions.
Serving 29 provinces and exporting to major international markets with speed.
Selection depends on the metal type (ferrous vs. non-ferrous), the storage environment (indoor vs. outdoor), the required protection duration, and the subsequent processing steps (such as welding or painting).
Every batch undergoes ASTM-standard salt spray testing and humidity cabinet testing. Our ISO certifications and PICC insurance provide a secondary layer of quality assurance for international buyers.
We offer specialized "residue-free" and "low-conductivity" rust preventives specifically designed for delicate electronic hardware and sensitive metallic surfaces.
Typically, our oils offer a shelf life of 2-3 years in sealed containers. Once applied, protection can range from 6 months (outdoor) to 5 years (indoor sheltered), depending on the formula.
