Product Description
Core Product Overview
Carbon Steel Plate (ASTM A36 / SS400 / Q235B / Q355B) is a cost‑effective ferrous structural steel material, widely recognized as the preferred option for construction frameworks, mechanical fabrication, pressure components and general engineering projects requiring outstanding mechanical strength, excellent weldability and formability. Compared with alloy steel grades, carbon steel delivers balanced performance at competitive cost, making it highly practical for conventional indoor and outdoor working conditions.
Our full stock range covers thin plates (0.1mm‑3mm), medium plates (3mm‑25mm), thick plates (25mm‑100mm) and extra‑thick plates over 100mm, with surface options including hot‑rolled black finish, pickled & oiled, cold‑rolled bright, brushed and embossed finish. Every batch is sourced from top domestic and international steel mills, with 100% material test report (MTR) provided before delivery.

Unmatched Performance Advantages
Superior Structural Strength & Weld‑ability
Balanced carbon‑iron composition delivers reliable tensile and yield performance. Carbon steel features excellent welding property, forming performance and mechanical toughness, suitable for various structural load‑bearing scenarios. It performs steadily under static and dynamic load conditions for general engineering construction.
Good Cost‑Efficiency & Processing Compatibility
Compared with alloy and stainless steel grades, carbon steel provides qualified comprehensive mechanical performance at competitive material cost. It supports multiple thermal and cold processing operations without excessive cost increase, greatly lowering overall project investment.
Reliable Low‑Temperature Toughness
Selected grades guarantee stable impact resistance under low‑temperature surroundings, avoiding brittle fracture for outdoor structural parts, equipment bases and transportation facilities operating in cold climate regions.
Outstanding Fabrication Versatility
It features good cold bending, hot forming and machining performance. Laser cutting, plasma cutting, flame cutting, stamping, drilling and welding can be completed smoothly without frequent cracking during processing.
