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 armoring manufacturers, light steel framing fabricators, galvanized pipe producers, hardware makers, and steel distributors in 78+ countries. We provide mill-direct pricing, custom slitting, and rapid export dispatch through Tianjin Port. Galvanized narrow steel strips 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 galvanized narrow strips, specific zinc coating weight, steel grades, width tolerances, surface treatment, and edge condition are available on request. Please share your target application, forming process, and corrosion requirement so we can recommend a suitable specification.

We support flexible order planning for cable makers, roll-formers, pipe producers, 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 stamping. The zinc coating provides barrier and sacrificial protection for indoor and outdoor applications. Specific corrosion performance and coating adhesion data are available on request.
Electrical and cable protection: armor tape for power cables, electrical metallic tubing, cable tray channels, and grounding strips
Construction and light steel framing: C/Z purlins, drywall studs, ceiling channels, window frame profiles, and door jambs
Pipe and conduit manufacturing: ERW galvanized tubes, irrigation pipes, and scaffolding tubes
Hardware and industrial goods: hose clamps, metal strapping, packaging seals, brackets, and greenhouse arches
General roll-forming and steel 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 or steel crates. This packaging is suitable for long-distance container shipment and safe unloading.
