Copper & Carbon Steel Lines Expanded

April 10, 2026 — 25+ new carbon steel grades and major copper product range expansion

Jiangsu Ranboyu Metal Products Co.,Ltd is excited to announce a major expansion of our carbon steel and copper & copper alloy product lines. In response to growing global demand, we have added over 25 new carbon steel grades and significantly broadened our copper, brass, and bronze offerings across all product forms.

Carbon Steel — New Grades Added

Our carbon steel portfolio has been expanded to cover a wider range of applications and strength levels. New grades now available include:

Category New Grades Typical Applications
Alloy Steel4130, 4140, 4340, 8620Gears, shafts, automotive, oil & gas
Pressure VesselA516 Gr.60, Gr.65, Gr.70Boilers, pressure vessels, storage tanks
Structural (EN)S355JR, S355J2, S275JR, S460NConstruction, bridges, heavy machinery
PipelineAPI 5L X52, X60, X65Oil & gas transmission pipelines
Tool SteelD2, H13, O1, A2Dies, molds, cutting tools
Wear-ResistantAR400, AR500, Hardox 450Mining, quarrying, earthmoving

All new carbon steel grades are available in our standard product forms: plates, coils, pipes, bars, and wires. We can also arrange custom-cut dimensions and heat treatment conditions (normalized, quenched & tempered, annealed) to your specifications.

Copper & Copper Alloys — Expanded Range

Our copper product line has been substantially broadened to serve a wider range of electrical, thermal, and corrosion-resistant applications:

Alloy Type Grades Available Product Forms
Pure CopperT1, T2, T3, TU1, TU2, C10100, C10200, C11000Tubes, plates, bars, wires, rods
Brass (Cu-Zn)H62, H65, H68, H70, H80, C26000, C27000, C28000Tubes, bars, plates, wires
Bronze (Cu-Sn)CuSn6, CuSn8, CuSn10, C51000, C52100Bars, plates, wires
Aluminum BronzeCuAl10Ni5Fe4, CuAl9Ni3Fe2, C63000Bars, tubes, forgings
Copper-Nickel90/10 (C70600), 70/30 (C71500)Tubes for marine/offshore

Increased Production Capacity

Alongside the product line expansion, we have also invested in additional production capacity to reduce lead times and improve stock availability:

  • Carbon Steel — Annual capacity increased by 40%, with new slitting and cut-to-length lines for faster plate and coil processing.
  • Copper Alloys — New continuous casting line for copper and brass bar production, reducing lead times by 30%.
  • Warehousing — Additional 5,000 m² of covered warehouse space dedicated to carbon steel plate and copper tube stock.

What This Means for Jiangsu Ranboyu Metal Products Co.,Ltd Customers

With this expansion, Jiangsu Ranboyu Metal Products Co.,Ltd now offers one of the most comprehensive multi-material portfolios in the metals supply industry. Customers benefit from:

  • Single-Source Convenience — Source stainless steel, carbon steel, and copper all from one trusted supplier, simplifying procurement and reducing administrative overhead.
  • Expanded Grade Selection — More material options means better optimization of cost vs. performance for every application.
  • Reduced Lead Times — Increased inventory and production capacity translate directly into faster deliveries.
  • Competitive Pricing — Economies of scale from our expanded operations help keep prices competitive across all product categories.
