High Strength Carbon Steel Plate for Structural and Industrial Use
Carbon steel plates in a wide range of grades and thicknesses. Suitable for bridges, machinery, pressure vessels, shipbuilding, and more. Available in cut-to-size, with fast delivery.
What Is Carbon Steel Plate?
Carbon steel plate is a flat steel sheet made from carbon-rich alloy with superior mechanical strength and cost-effectiveness. It is widely used in structural fabrication, machine parts, automotive frames, pressure vessels, and shipbuilding.
We supply carbon steel plates in:
- Mild Steel (Low Carbon)– Easy to cut, weld, and shape
- Medium/High Carbon– Better hardness and strength
- Boiler & Pressure Vessel Grade– Excellent toughness
- Shipbuilding Grade– High tensile, seawater-resistantAbrasion-Resistant Plate– For mining and construction

Frequently Asked Questions
Q1: What is the difference between mild steel and structural plate?
Mild steel is low carbon and easily formable; structural plates like Q345 or S355 have higher strength and are used in load-bearing applications.
Q2: Do you supply boiler-grade carbon steel plate?
Yes. We offer ASTM A516, Q245R, and related grades suitable for pressure vessels and tanks.
Q3: Can you cut the plate into parts or flanges?
Absolutely. We support precision plasma cutting to custom drawings.
Q4: What are your available thicknesses?
We stock from 2mm thin sheets to 300mm heavy plates.
Q5: Is carbon steel plate suitable for outdoor environments?
Yes, especially grades like A588 or painted surfaces for weather resistance.
