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 black annealed, bright, and galvanized steel strips to tube and pipe manufacturers, furniture tube producers, structural hollow section makers, and steel service centers in 78+ countries. We provide mill-direct pricing, custom slitting, and rapid export dispatch through Tianjin Port. Black steel strips for tube and pipe making 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
Specific tube-making grades, surface types such as HRP&O or HR black strip, tensile strength, and width tolerances are available on request. Please share your target pipe application, welding method, and required mechanical properties so we can recommend a suitable specification.

We support flexible order planning for ERW/HFW pipe mills, furniture tube makers, hollow section producers, and distributors. Specifications can be adjusted according to end use, processing method, and destination market requirements.
Black annealed steel strip offers good ductility and formability for tube and pipe making. It can support roll forming, seam welding, bending, and flattening processes. A clean edge and consistent width help improve seam alignment and reduce feeding problems in continuous tube mills. Specific weldability and mechanical data are available on request.
Furniture and decorative tubing: thin-wall round, square, and oval steel tubes for tables, chairs, office furniture, and display racks
Structural hollow sections: square and rectangular structural pipes, scaffolding tubes, construction posts, and frame supports
Automotive and mechanical tubing: exhaust pipes, shock absorber casings, drive shaft tubes, and steering column sleeves
Agricultural and fencing pipe: greenhouse frame tubing, livestock enclosure pipes, guardrail posts, and gate rails
General tube making and steel fabrication
Every batch undergoes inspection, including tensile strength, elongation, hardness, width, and surface checks. Additional testing is available on request. A Mill Test Certificate (MTC) can be supplied on request, and third-party inspection is available on request.
To reduce moisture penetration, surface rust, and coil edge deformation during sea transport, our steel 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.
