What are the common thickness specifications?
Hot-rolled: 1.5~14mm; Cold-rolled: 0.3~3.0mm, special thicknesses can be customized.
What is the standard width?
Common widths: 800mm, 1000mm, 1250mm, 1500mm, can be slit as needed.
What are the typical inner and outer diameters of steel coils?
Inner diameter: 508mm (20 inches), 610mm (24 inches); Outer diameter: 1000~1800mm, depending on coil weight.
What are the thickness tolerance standards?
Standard tolerance: ±0.05~±0.15mm. Cold-rolled precision is higher than hot-rolled. Special requirements can be customized.
What is the weight range of a single coil?
Generally 3~15 tons. Thinner coils are lighter, thicker coils are heavier, depending on the transportation and processing equipment.
