Carbon Steel Plates

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional carbon steel plates manufacturers and suppliers in China. Welcome to wholesale customized carbon steel plates at competitive price from our factory. Good service and quality products are available.

 

Carbon Steel Plate is one of the most widely used steel products, primarily composed of iron and carbon, with small amounts of manganese, silicon, sulfur, and phosphorus. The carbon content typically ranges from 0.05% to 0.30%, which directly influences the steel's strength, hardness, and weldability.

 

Due to its excellent mechanical properties, easy fabrication, and cost efficiency, carbon steel plate is extensively used in construction, manufacturing, pressure vessels, shipbuilding, and general engineering projects worldwide.

 

 

• Good strength and toughness
• Excellent weldability and machinability
• Stable mechanical performance
• Wide availability in multiple grades
• Cost-effective for large-scale projects
• Suitable for hot-rolled and normalized conditions

These advantages make carbon steel plate a fundamental material in both light and heavy industries.
