Authentic Steel is the export department of Winroad Group and a professional manufacturer and exporter of steel strips and narrow coils. From our production hub in Tianjin, China, we supply galvanized steel strips to cable manufacturing plants, electrical infrastructure contractors, hardware producers, and steel distributors in 78+ countries. We provide mill-direct pricing, custom slitting, and rapid export dispatch through Tianjin Port. Galvanized steel strips for cable armoring are available on request.
According to our company brochure, the standard steel strip range is:
Types: Black annealed / Bright / Galvanized
Thickness: 0.2–4.5 mm
Width: 30–870 mm
Coil weight: 3–13 MT
Coil inner diameter: 508 / 610 mm
For cable armoring applications, specific thickness, width, zinc coating, mechanical properties, winding format, and edge condition are available on request. Please share your target cable diameter, wrapping process, and corrosion requirement so we can recommend a suitable specification.

We support flexible order planning for cable makers, electrical contractors, hardware fabricators, and distributors. Specifications can be adjusted according to end use, processing method, and destination market requirements.
Galvanized steel strip offers zinc coating protection and good formability. It is suitable for slitting, roll forming, bending, and wrapping. The zinc coating provides barrier and sacrificial protection for cable armoring and other outdoor applications. Specific corrosion performance, elongation, and coating adhesion data are available on request.
Underground power distribution: armoring LV/MV/HV underground power cables against soil load and excavation impacts
Submarine and offshore cables: protective steel tape armor for subsea power lines and offshore cables
Telecommunications and fiber optics: armoring optical fiber cables and signal cables against rodent damage and moisture ingress
Industrial and mining cables: heavy-duty trailing cables, railway signaling, airport lighting, and chemical plant wiring
General cable protection and steel strip fabrication
Every batch undergoes inspection, including tensile strength, elongation, hardness, width, and surface checks. Zinc coating thickness measurement, bend tests, and salt spray testing are available on request. A Mill Test Certificate (MTC) can be supplied on request, and third-party inspection is available on request.
To reduce white rust, moisture penetration, and coil edge deformation during sea transport, our galvanized strips use multi-layer export packaging: rust-inhibiting VCI paper, plastic moisture barriers, metallic corner protectors, high-tensile radial and circumferential steel banding, and solid wooden pallets, steel crates, or wooden spools. This packaging is suitable for long-distance container shipment and safe unloading.
