B2B Industrial Steel Strips Manufacturer & Custom Slitting Supplier
Precision Slitted Steel Strip Supply for OEM Manufacturers & Metal Fabricators
Authentic Steel provides industrial-grade slitted steel strips (narrow steel coils) custom-processed to meet the rigorous manufacturing standards of global tube mills, hardware stamping plants, and structural profile manufacturers. Operating out of our steel processing hub near Tianjin Port, China, we convert prime master coils into precision-slitted narrow coils. By supplying ready-to-use strip dimensions directly to your production line, we help international B2B buyers optimize material utilization, reduce secondary slitting overheads, and streamline inventory management.
Slitting Process Controls & Tight Tolerance Specifications
Production of high-speed continuous stamping and high-frequency welded (ERW) pipes requires rigid physical and dimensional consistency. Authentic Steel utilizes automated rotary slitting lines equipped with carbide blades to maintain exceptional processing accuracy across all strip batches:
Width Tolerances: Controlled within strict precision limits (±0.03 mm to ±0.05 mm), ensuring seamless feeding into progressive stamping dies and roll-forming cassettes.
Camber Control (Side Bow): Monitored to remain within ≤1.5 mm per 2,000 mm length, eliminating jam risks in automated manufacturing lines.
Burr Height Mitigation: Rotary shear clearance is micro-adjusted to limit edge burr height below 5% of nominal material thickness. Deburred or rounded edge options are available upon request for enhanced handling safety and severe bending operations.
Material Grade Portfolio & B2B Industry Applications
We offer slitted steel strips across multiple metallic substrates and metallurgical grades to match your specific engineering specifications:
Cold Rolled Steel Strips (CRC): Available in SPCC, SPCD, DC01–DC04, and SAE 1008/1010 grades for precision automotive stampings, cabinet slides, and deep-drawn components.
Galvanized Steel Strips (GI): Available in DX51D+Z, SGCC, and ASTM A653 CS Type B (Zinc coating Z40 to Z275 g/m²) for HVAC duct flanges, cable trays, and drywall studs.
Hot Rolled Steel Strips (HRC): Available in Q235B, Q355B, S235JR, and S355JR for ERW structural tubing, highway guardrails, and heavy-duty brackets.
High-Tensile Packaging Strips: Engineered for heavy-duty industrial strapping and pallet securing.
B2B Export Packaging & Logistics Compliance
To safeguard structural integrity against ocean freight humidity and mechanical impact, Authentic Steel adheres to heavy-duty export packaging standards. Strips are supplied in "Eye-to-Sky" or "Eye-to-Wall" coil configurations, treated with light rust-inhibitive oil, wrapped in VCI anti-rust film, encased in corrugated steel outer protections, and secured onto reinforced wooden pallets with heavy steel strapping. Contact our technical sales engineering team to request Mill Test Certificates (MTC compliant with EN 10204 3.1), chemical composition breakdowns, and volume-based FOB/CIF price quotes.
