RFID Metal Tag

Built for industrial metal asset identification, this RFID metal tag is designed for long-range UHF reading in harsh factory and logistics environments. The ABS hard-shell structure protects the internal antenna against vibration, moisture, and surface deformation commonly found on steel containers, machinery, racks, and returnable transport equipment. Operating at 920.5–924.5MHz with Higgs3 IC, the tag supports up to 8 meters reading distance under stable reader configuration. As a China RFID metal tag manufacturer and bulk supplier, we support EPC pre-encoding, laser marking, frequency tuning, and OEM serialization for large-scale industrial deployment.

Industrial RFID deployment on metal surfaces is fundamentally different from standard label tagging. Conventional RFID labels lose efficiency or completely detune when attached directly onto conductive materials. This UHF anti-metal tag uses a dedicated antenna isolation structure combined with ABS housing thickness control to stabilize resonance against steel surfaces.
The 118×33×12.2mm structure is intentionally oversized compared with compact anti-metal stickers. The additional cavity height improves antenna separation from conductive substrates, which directly affects reading consistency in dense warehouse environments.
The internal antenna size of 94.8×8.2mm is optimized for directional reading stability instead of ultra-miniaturization. In industrial projects, stable reading performance is usually more important than reducing physical size.

The ABS housing is selected not for appearance, but for dimensional rigidity. Flexible labels often experience antenna deformation after long-term compression or thermal cycling. In contrast, rigid ABS housing maintains antenna geometry stability during outdoor installation and forklift impact conditions.

In real industrial environments, anti-metal RFID performance is affected more by surrounding interference than theoretical read distance.

For example, metal stacking conditions can create severe signal reflection and phase cancellation. In high-density warehouse installations, tags mounted less than 50mm apart may produce inconsistent read sequencing if antenna polarization is improperly configured.

In industrial maintenance projects, User Memory 512bit becomes especially useful. Instead of storing only EPC codes, system integrators can allocate sections for:

Maintenance cycle records/Internal equipment classification/Factory department allocation/Inspection timestamps/Asset lifecycle stages

This reduces backend database dependency during temporary offline operations.

Another common deployment issue involves painted metal surfaces. Thick epoxy coatings may slightly alter spacing between tag and conductive substrate. Although this usually improves isolation, inconsistent coating thickness across assets can create minor reading fluctuations. For this reason, field testing before mass deployment is strongly recommended.
