How to Choose the Right Thick Steel Plate Grade

Selecting the correct thick steel plate grade directly affects safety and cost. Consider working load, temperature range, and welding requirements. Low-carbon grades like Q235B suit general structures, while high-strength Q460 or S690 plates serve cranes and machinery.
