You are ready to order stainless steel coil¹s. The supplier asks for the MOQ². The shipping company needs to know how many coils fit in a container. You need to plan your order.

Stainless steel coil MOQ² typically ranges from 5 to 20 tons for standard sizes and grades. A 20-foot container can hold 20-25 tons of coils, depending on coil dimensions. A 40-foot container can hold 25-28 tons. Coils must be loaded vertically (eye to the sky) on coil racks or in stillages, properly secured to prevent movement.

I have shipped stainless steel coil¹s to many countries. A customer in the UAE ordered 20 tons in a 20ft container. A customer in the US ordered 50 tons in two 40ft containers. Let me walk you through MOQ² and container loading.

What is the working load limit¹ for coil racks²?

The working load limit¹ (WLL) for coil racks² varies by design, but typical coil racks² for shipping containers have a WLL of 2,000 to 4,000 kg per rack. Heavy-duty racks can handle up to 6,000 kg.

Coil racks (also called coil cradles or coil saddles) are steel frames used to secure coils inside shipping containers. The WLL is determined by the rack's construction, material, and design. Always use racks certified for the coil weight. Never exceed the rated WLL.

Coil Rack Types and Capacities

Let me provide typical working load limit¹s for coil racks².

Standard Coil Racks for Containers

Rack Type	WLL (kg)	Coil Width (mm)	Best For
Light duty	2,000	Up to 600	Small coils
Standard duty	3,000	Up to 800	Most coils
Heavy duty	4,000-5,000	Up to 1,000	Large coils
Extra heavy duty	6,000	Up to 1,200	Very large coils

Rack Materials

Material	Strength	Cost
Steel (standard)	Good	Moderate
Steel (reinforced)	Excellent	Higher
Aluminum	Lightweight	High

Safety Factors

• Coil racks typically have a 5:1 safety factor (WLL = breaking strength / 5)
• Always check the manufacturer's certification
• Inspect racks for damage before each use

My Experience
We use standard duty coil racks² (WLL 3,000 kg) for most shipments. For heavier coils, we use heavy duty racks (WLL 5,000 kg).

How to load steel coils¹ on a ship?

Steel coils are loaded on ships using containers (LCL or FCL) or break bulk (for very large coils). For container shipping², coils are loaded into containers at the warehouse, then the containers are loaded onto the ship.

The process: coils are placed on coil racks or stillages, secured with banding and blocking, and the container is sealed. For break bulk, coils are loaded directly onto the vessel using cranes with coil lifting beams. Proper securing is critical to prevent movement during transit.

Loading Methods and Steps

Let me explain the loading methods for steel coils¹.

Container Shipping (FCL - Full Container Load)

Step	Action
1	Coil placed on coil rack or stillage
2	Coil secured with steel banding (4-8 straps)
3	Rack secured to container floor with blocking
4	Container sealed
5	Container loaded onto ship

Break Bulk Shipping (for large coils)

Step	Action
1	Coil lifted with coil lifting beam
2	Placed in vessel's hold
3	Secured with dunnage and banding
4	Blocked and braced to prevent rolling

Coil Orientation

Orientation	Description	Best For
Eye vertical (eye to sky)	Coil stands on edge	Standard container loading
Eye horizontal (eye to side)	Coil lies flat	Break bulk, flat racks

Securing Requirements

• Steel banding: 4-8 straps per coil
• Edge protectors: Cardboard or plastic to prevent damage
• Blocking: Lumber to prevent rolling
• Dunnage: Air bags or bracing

My Experience
For container shipments, we always load coils eye vertical on coil racks. The coils are banded and the racks are blocked to prevent movement.

What is the loading capacity of a 20FT and 40FT container?

A 20ft standard container has a maximum loading capacity¹ of about 22-25 tons (20,000-22,000 kg payload). A 40ft standard container has a maximum capacity of about 26-28 tons (24,000-26,000 kg payload).

The payload capacity² depends on the container's tare weight and the vessel's weight limits. For stainless steel coils, you will typically reach the weight limit before filling the volume. A 20ft container can hold 20-25 tons of coils. A 40ft container can hold 25-28 tons.

Container Capacity Details

Let me provide detailed capacity information.

20ft Standard Container

Parameter	Value
Internal dimensions (L×W×H)	5.9m × 2.35m × 2.39m
Maximum gross weight	30,480 kg (67,200 lbs)
Tare weight	2,200-2,400 kg
Maximum payload	22,000-25,000 kg
Typical coil load	20-25 tons

40ft Standard Container

Parameter	Value
Internal dimensions (L×W×H)	12.03m × 2.35m × 2.39m
Maximum gross weight	30,480 kg (67,200 lbs)
Tare weight	3,700-3,900 kg
Maximum payload	26,000-28,000 kg
Typical coil load	25-28 tons

Coil Loading Examples

Coil Weight	20ft Container	40ft Container
2,000 kg	10-12 coils	13-14 coils
3,000 kg	7-8 coils	8-9 coils
4,000 kg	5-6 coils	6-7 coils
5,000 kg	4-5 coils	5-6 coils

My Experience
For a shipment of 3,000 kg coils, we loaded 8 coils (24 tons) in a 20ft container. The weight was within the 25-ton limit.

What are the safety guidelines for stacking and storage of steel coils¹?

Steel coils must be stored vertically (eye to the sky) on flat, level surfaces. Never store coils on their sides (eye horizontal) unless secured in racks. Stacking is limited to one or two coils high, with proper dunnage between layers.

Safety guidelines: store coils on concrete or steel floors, use coil racks or wooden dunnage, keep aisles clear for forklift access, inspect coils for damage before moving, and never exceed rack weight limits. For long-term storage, protect coils from moisture with tarps or indoor storage.

Storage Safety Guidelines

Let me provide key safety guidelines for storing steel coils¹.

Proper Storage Orientation

Orientation	Safe?	Guidelines
Eye vertical (eye to sky)	Yes	Standard storage, coils sit on edge
Eye horizontal (eye to side)	No	High risk of rolling, only in racks

Stacking Guidelines

Stack Height	Requirement
1 coil high	Safe for most coils
2 coils high	Requires flat surface and dunnage between layers
3+ coils high	Not recommended (unstable)

Storage Surface Requirements

• Flat, level concrete floor
• Steel floor plates for heavy coils
• Coil racks or stillages for stability

Safety Precautions

• Use coil racks for eye horizontal storage only
• Place chocks or wedges to prevent rolling
• Keep aisles clear for forklift access
• Inspect coils for damage before moving
• Never exceed rack weight limits
• Use appropriate lifting equipment (coil lifting beams)

My Experience
In our warehouse, we store coils eye vertical on concrete floors with wooden dunnage. We never stack more than two coils high.

Conclusion

Stainless steel coil MOQ¹ is typically 5-20 tons. A 20ft container holds 20-25 tons; a 40ft holds 25-28 tons. Coil racks have WLL of 2,000-6,000 kg. Store coils eye vertical on flat surfaces, never stack more than two high.
