Explore our core selection of certified cold-rolled, hot-rolled, and specialized steel coils engineered for extreme structural performance and corrosion resistance.
In the highly demanding sectors of modern home appliance manufacturing, consumer electronics, and premium architectural installations, the aesthetic integrity and surface longevity of metal parts are critical determinants of brand value. Standard cold-rolled and galvanized steel sheets, while structurally robust, are highly susceptible to oil-based contaminants, acid perspiration from handling, and atmospheric oxidation. Anti-Fingerprint (AFP) Cold-Rolled Steel represents a monumental technological leap, solving surface vulnerability by applying a nano-scale organic-inorganic composite passivation barrier on the substrate.
As global manufacturers shift toward automated production systems and lean assembly lines, the requirement for raw materials that bypass post-assembly surface treatment has grown exponentially. Standard cold-rolled steel requires degreasing, cleaning, and painting after stamping. By implementing pre-coated Anti-Fingerprint Cold-Rolled Coils directly into progressive stamping dies, OEM factories can eliminate secondary finishing processes, reducing production cycle times, carbon emissions, and operational costs.
A multi-layered protective barrier engineered at the molecular level to optimize corrosion resistance, weldability, and aesthetic appeal.
The foundation is composed of high-ductility cold-rolled steel (CQ, DQ, DDQ grades) combined with a hot-dip galvanized (GI) or electro-galvanized (EG) zinc coating. This provides sacrificial anodic protection to the underlying steel substrate against structural rust.
A conversion coating applied directly on top of the zinc layer. Modern environmental specifications mandate Chrome-Free (Cr-free) passivation treatments. This layer chemically stabilizes the zinc surface, preparing it for the organic topcoat adhesion.
An ultra-thin organic polymer resin film formulated with colloidal silica. The silica particles improve hardness, scratch resistance, and friction characteristics during stamping, while the organic polymer resin provides the hydrophobic, fingerprint-shedding qualities.

| Salt Spray Test (SST) | < 24 Hours to Red Rust | > 72 to 120 Hours (White Rust Free) | Extended service life in humid climates |
| Coefficient of Friction | 0.18 - 0.22 (Requires lubrication) | 0.08 - 0.12 (Dry Lubricating Effect) | Optimized tool life, eliminates drawing oils |
| Electrical Contact Resistance | Low | < 0.1 mΩ (Highly Conductive) | Ideal for electromagnetic shielding (EMI) and grounding |
| RoHS/REACH Compliance | N/A | Certified Chrome-Free Options | Complies with strict European export regulations |
Leveraging Hebei's dense industrial integration to deliver rapid shipping, strict cost controls, and exceptional metallurgical quality.
Hansheng Technology (Hebei) Co., Ltd. is strategically situated in Tangshan City, Hebei Province—the heart of China’s steel industry. This geographical position gives us direct access to high-purity iron ore, raw steel refining complexes, and downstream energy grids. By reducing intermediate transport of raw slabs, our factory reduces production overheads, translating to highly competitive FOB/CIF pricing for global wholesalers.
With our manufacturing facility located just 150 kilometers from the major logistics hub of Tianjin seaport and 150 kilometers from Beijing, we maintain an unparalleled logistics pipeline. Goods are loaded and dispatched to port terminals within hours of customs clearance, securing swift transit times to international destinations.
Established in 2006, our enterprise has spent nearly two decades refining cold rolling and surface passivation technology. We currently operate 8 high-efficiency production lines, delivering an annual production output of up to 650,000 metric tons. Our lines feature automated inline thickness-gauge correction and spectrophotometric coating control systems, ensuring uniform distribution of the anti-fingerprint layer across the entire width of the coil.
Every production batch undergoes a rigorous pre-shipment quality control process. We execute tension-leveling, mechanical bend tests, and paint adhesion tests under ISO9001:2000 and ISO14001 certification frameworks, ensuring compliance with global standards.
From high-exposure home appliances to rugged electrical infrastructure, AFP cold-rolled coils are key to clean, durable construction.
Widely used for refrigerator door panels, microwave oven wrappers, washing machine drums, and range hoods. The anti-smudge surface reduces maintenance needs, while keeping household appliances looking pristine throughout their operational lifespan.
Used in high-humidity climate zones for premium HVAC ducting, industrial ventilation, and dampeners. The superior salt spray performance of anti-fingerprint zinc coatings prevents galvanic corrosion at joints and fastening points.
Protective housings for servers, telecommunications switchboards, and electrical control panels demand fingerprint resistance to preserve clean interiors during installation. Excellent surface conductivity maintains grounding effectiveness.
Office partitions, metal desks, and filing cabinets constructed from AFP sheets withstand heavy daily interaction without cumulative fingerprint staining, reducing the need for aggressive solvent-based chemical cleaners.
Critical brackets, stamped brackets, and mechanical mounting kits utilize the dry lubricating properties of the AFP polymer layer, allowing stamping without complex drawing lubricants, accelerating high-volume component manufacturing.
Interior structural braces, ECU housing enclosures, and audio frame structures within automotive chassis take advantage of the combined benefits of high corrosion resistance, light weight, and deep-drawing properties.

How technical advancements and green regulations are redefining surface treat technologies in the steel value chain.
Global environmental guidelines are strictly pushing for the elimination of hexavalent chromium (Cr6+) in coating structures. Our manufacturing lines utilize state-of-the-art organosilane compounds that achieve equivalent, or in some cases superior, anti-corrosion metrics compared to traditional chromate passivation.
Future coatings integrate self-healing mechanisms and anti-static properties. By modifying the silica matrix with specialized micro-capsules, the coating can seal microscopic scratches automatically when exposed to atmospheric moisture, maintaining visual perfection.
Advanced polymer formulations now integrate solid state lubricants. This allows components to undergo deep drawing without any external lubrication oil. This cuts out post-stamping wash processes, significantly reducing energy costs for manufacturing plants.
