Actual weight may vary by \u00b13-5% due to manufacturing tolerances (ASTM A568) and density variations. For exact weights, refer to mill test certificates.<\/div>\r\n <\/div>\r\n <div class=\"faq\">\r\n <div class=\"faq-question\" onclick=\"toggleFAQ(this)\">What is the standard inner diameter of a steel coil?<\/div>\r\n <div class=\"faq-answer\">The most common inner diameters are 508 mm (20 inches) and 610 mm (24 inches). These sizes are standardized to fit most decoiling equipment and mandrels.<\/div>\r\n <\/div>\r\n <div class=\"faq\">\r\n <div class=\"faq-question\" onclick=\"toggleFAQ(this)\">How do I calculate coil length from weight?<\/div>\r\n <div class=\"faq-answer\">Length (m) = Weight (kg) \u00f7 [Width (m) \u00d7 Thickness (mm) \u00d7 Density (kg\/m\u00b3) \u00f7 1000]. For carbon steel: Length = Weight (kg) \u00f7 (Width(m) \u00d7 Thickness(mm) \u00d7 7.85).<\/div>\r\n <\/div>\r\n <div class=\"faq\">\r\n <div class=\"faq-question\" onclick=\"toggleFAQ(this)\">What is a typical steel coil weight?<\/div>\r\n <div class=\"faq-answer\">Steel coils typically weigh between 3 and 30 metric tons, with common ranges being 5-15 tons. Hot-rolled coils tend to be heavier, while cold-rolled and galvanized coils are often 3-10 tons.<\/div>\r\n <\/div>\r\n <div class=\"faq\">\r\n <div class=\"faq-question\" onclick=\"toggleFAQ(this)\">How much does a 2mm \u00d7 1250mm carbon steel coil weigh per meter?<\/div>\r\n <div class=\"faq-answer\">Approximately 19.63 kg\/m.
