If you are sourcing steel coil for sale from international suppliers, one of the first questions you will ask is: how many tons does a coil weigh? Understanding steel coil weight is essential for freight calculation, container loading, handling equipment selection, and cost budgeting. This guide provides standard weight specifications for gi coil, Cold rolled steel Coil, cr coil, steel coil hot, and steel coil galvanized—so you know exactly what to expect when placing your order.
Steel coils typically weigh between 3 tons and 30 tons per coil, depending on thickness, width, and material type. Here are the typical weight ranges for common products:
| Product Type | Typical Coil Weight | Notes |
|---|---|---|
| Steel coil galvanized (GI coil) | 3 – 20 tons | Standard ID: 508mm or 610mm |
| Cold rolled steel Coil (cr coil) | 3 – 15 tons | Commonly 5–15 tons for CRC |
| Steel coil hot (HRC) | 8 – 32 tons | Regular weight: 18–28 tons |
| PPGI / prepainted coil | 5 – 20 tons | Varies by coating and substrate |
| Light gauge coil | 3 – 8 tons | Thin sheets for roofing, appliances |
| Heavy gauge coil | 15 – 30 tons | For construction, shipbuilding, pipes |
Most standard export steel coils fall in the 5–25 ton range, with 8–15 tons being the most common for general applications. A typical 24 ton steel coil price inquiry usually refers to a heavy-gauge hot rolled or galvanized coil.
The fundamental formula for calculating steel coil weight is straightforward:
Weight (kg) = Thickness (mm) × Width (mm) × Length (m) × Density (g/cm³) ÷ 1000
For steel coil galvanized, a practical formula used by manufacturers is:
Weight per meter (kg/m) = 7.85 × Width (m) × Thickness (mm) × 1.03
The 1.03 factor accounts for the additional weight of the zinc coating.
When you know the coil's outer diameter (OD), inner diameter (ID), and width, use the annulus volume formula:
Weight (kg) = π × (OD² − ID²) × Width × Density ÷ 4,000,000
Where:
π ≈ 3.1416
OD = Outer Diameter (mm)
ID = Inner Diameter (mm) – standard IDs are 508mm (20") or 610mm (24")
Width = Coil Width (mm)
Density = 7.85 g/cm³ for carbon steel, 8.05 g/cm³ for galvanized steel
Example 1 (Weight → Length):
A carbon steel coil, 2.5 mm thick × 1000 mm wide, weighing 12 tons.
Length = 12,000 kg ÷ (2.5 × 1000 × 7.85 ÷ 1000) ≈ 611 meters
Example 2 (Thickness → Weight per meter):
A galvanized coil, 0.4 mm thick × 1200 mm wide.
Weight per meter = 7.85 × 1.2 × 0.4 × 1.03 = 3.88 kg/m
For a 1000-meter coil: 3.88 × 1000 = 3.88 tons
Example 3 (OD/ID → Weight):
A coil with OD = 1300 mm, ID = 508 mm, Width = 1250 mm, galvanized steel (density 8.05 g/cm³).
Weight ≈ (3.1416 × (1300² − 508²) × 1250 × 8.05) ÷ 4,000,000 ≈ 11.7 tons
| Thickness (mm) | Width (mm) | Weight per meter (kg/m) | Approx. weight for 1000m coil (tons) |
|---|---|---|---|
| 0.30 | 1000 | 2.36 | 2.36 |
| 0.50 | 1000 | 3.93 | 3.93 |
| 0.80 | 1250 | 7.85 | 7.85 |
| 1.00 | 1250 | 9.81 | 9.81 |
| 1.50 | 1250 | 14.72 | 14.72 |
| 2.00 | 1250 | 19.63 | 19.63 |
| 3.00 | 1250 | 29.44 | 29.44 |
Calculated using carbon steel density (7.85 g/cm³). Galvanized coils add approximately 3% to these values.
| Coil Type | Typical Thickness | Typical Width | Coil Weight Range | Common Applications |
|---|---|---|---|---|
| Steel coil galvanized (GI) | 0.12 – 6.0 mm | 600 – 1500 mm | 3 – 20 tons | Roofing, cladding, automotive |
| Cold rolled steel Coil (CRC) | 0.25 – 3.0 mm | 600 – 2000 mm | 3 – 15 tons | Appliances, automotive panels |
| Steel coil hot (HRC) | 1.2 – 20 mm | 600 – 2000 mm | 5 – 30 tons | Structural, pipes, shipbuilding |
| PPGI / prepainted | 0.16 – 2.0 mm | 600 – 1500 mm | 5 – 20 tons | Architectural, roofing |
Understanding coil weight is critical for container loading:
| Container Type | Max Payload | Typical Coils per Container |
|---|---|---|
| 20-foot container | ~28 tons | 2–3 coils (depending on individual weight) |
| 40-foot container | ~26.5 tons | 2–4 coils |
Coils must be properly blocked and braced to prevent shifting during transit.
Steel coil packaging adds approximately 50–200 kg per coil depending on:
Inner packaging: VCI paper, waterproof film
Outer packaging: Galvanized steel sheet or coated steel sheet wrapping
Edge protectors: Cardboard or plastic
Steel strapping: 4–7 steel straps around the coil
When calculating total shipping weight, always include the steel coil package weight in your freight calculations.
