A 12mm HR (Hot Rolled) Sheet is a heavy-duty steel plate used across construction and manufacturing. They are priced by weight, typically ranging from ₹50 to ₹60 per kg, with a 12mm plate weighing approximately 94.2 kg per square meter. Weight Calculator: \(\text{Weight (kg/m}^2\text{)} = \text{Thickness (in mm)} \times 7.85\) (Standard MS Steel density). For 12mm, this equates to ~ 94.2 kg/m². Common Dimensions: 1250 mm × 2500 mm (8 × 4 ft), 1500 mm × 6000 mm, and custom lengths up to 12 meters (12m). Hot Rolled (HR) steel sheet sizes depend on the thickness, width, and length. Standard HR sheets generally range from 1.2 mm to 25.4 mm in thickness (material thicker than 25 mm is typically classified as a plate).
