Metal QR code tags are permanent identification tags manufactured from metals such as stainless steel, aluminium, or titanium, designed to carry machine-readable QR codes that remain scannable throughout the entire lifecycle of an asset.
Unlike printed labels or surface laser marking, metal QR tags are engineered to survive harsh industrial environments including heat, corrosion, abrasion, outdoor exposure, and chemical contact. This makes them suitable for regulated and safety-critical applications such as LPG cylinders, industrial equipment, and long-life assets.
Paper, polymer, or vinyl QR code labels are commonly used for consumer products and indoor assets. However, in industrial and LPG environments, these labels fail due to:
Once a printed label becomes unreadable, the digital traceability chain breaks, leading to loss of asset history, compliance gaps, and operational risk.
Laser marking directly on metal surfaces is often considered an alternative. However, laser-etched QR codes can become unreadable due to surface oxidation, repainting, mechanical wear, or low contrast after repeated use.
Metal QR code tags, when properly manufactured and affixed, provide:
LPG cylinders are high-risk assets governed by strict safety and compliance requirements. Each cylinder undergoes multiple filling cycles, inspections, testing, and movement across plants and distributors.
Metal QR code tags enable:
When combined with a secure backend system, metal QR tags become the physical anchor for digital compliance and audit trails.
The choice of metal depends on the operating environment and lifecycle requirements:
Selecting the right material ensures long-term readability and regulatory reliability.
In all these cases, metal QR code tags act as the bridge between physical assets and digital traceability systems.
