Hot-rolled steel plates are prized for their malleability and cost-effectiveness, making them ideal for structural frameworks and machinery bases. Carbon steel plates, such as 1020 or 1045, deliver higher tensile strength for load-bearing components like gears and shafts. Corten plates excel in outdoor settings due to their rust-resistant patina, while chequered plates enhance safety in walkways and staircases. For high-temperature environments, A516-grade plates ensure reliability in boilers and pressure vessels. Perforated plates offer versatility in filtration systems or architectural designs. Understanding these distinctions helps avoid over-engineering or underperformance. Focus on factors like environmental exposure, load requirements, and fabrication methods. Reputable suppliers provide certified materials (e.g., ASTM A36) and technical guidance to align your choice with project goals.
