Choosing metal coil automatic storage system essentially means selecting a complete solution encompassing "warehousing structure + handling equipment + intelligent control system," rather than individual devices. An inappropriate selection will negatively impact efficiency, safety, and return on investment.

The selection process requires a comprehensive evaluation from multiple dimensions, including production needs, storage structure, level of automation, safety, system software, equipment reliability, and return on investment. Below is a complete and systematic selection guide applicable to automated storage projects for steel coils, aluminum coils, and stainless steel coils.

1. 11 Core Requirements Must Clarified Before Procurement

This is the most crucial step in the selection process; 80% of selection problems stem from unclear requirements.

1) Storage Coil Type

Different coil materials determine the structural design.

Common Types:

- Carbon Steel Coil

- Stainless Steel Coil

- Aluminum Coil

- Copper Coil

- Galvanized Coil

Key Parameters:

- Inner Diameter: 508/610 mm

- Outer Diameter: 800–2200 mm

- Coil Width: 600–2000 mm

- Weight: 1–30 tons

Important Notes:

- Maximum Coil Weight

- Maximum Coil Diameter

- Maximum Coil Width

Different coil materials will affect:

- Rack Structure

- Pallet Design

- Clamping Method

- Conveying Equipment

2) Warehouse Capacity Requirements

Calculations needed: Daily Processing Volume

Example:

Daily Inbound: 120 rolls

Daily Outbound: 150 rolls

Inventory Cycle

Example: 7 day Inventory

Calculation:

Inventory Quantity = Daily Usage × Inventory Cycle

Example: 150 × 7 = 1050 rolls

Clarification needed:

- Planned Storage Quantity

- Future Expansion Required

This determines:

- Warehouse Size

- Number of Shelf Layers

- Number of Aisles

Recommendation:

- Reserve 20%–30% Expansion Space

- To avoid future reconstruction.

3) Roll Material Weight

A key indicator in roll material warehouse design.

Common Levels:

Weight Influence:

- Rack Load Capacity

- Stacker Crane Tonnage

- Conveying Equipment

4) Coil Diameter Range

Coil storage typically considers:

- Minimum Diameter

- Maximum Diameter

For example:

- Ø900–Ø1800 mm

When the diameter varies significantly, the following are required:

- Adjustable Pallets

- Adaptive Fixtures

5) Automation Level

The level of automation affects investment.

3 common types:

Automated systems can achieve automatic warehousing, automatic outbound warehousing, and intelligent scheduling.

6) Connection to Production Lines

Roll material warehouses typically need to connect to:

- Uncoiling Line

- Slitting Line

- Cross-cutting Line

- Stamping Production Line

- Packaging Line

Connection methods:

- Conveyor Line

- AGV

- RGV

- Overhead Crane

7) Factory Conditions

Must confirm:

- Factory height

- Ground load-bearing capacity

- Column spacing

- Fire safety regulations

For example:

8) Inbound Method

Common:

- Overhead crane loading

- Forklift loading

- Automated conveyor line

Higher automation level, higher efficiency.

9) Outbound Methods

Common:

- Transport to production line

- Automated delivery

- AGV delivery

10) Inbound/Outbound Frequency

This is a key factor affecting the automation structure.

Needs to confirm:

- Number of rolls inbound daily

- Number of rolls outbound daily

- Are there peak periods?

For example:

If connected to:

- Leveling line

- Laser cutting production line

- Stamping line

Then the following must be guaranteed: Rapid material supply capability

11) Information system

Modern warehouses must have:

- WMS warehouse management system

- WCS equipment control system

- ERP interface

- MES interface

This enables full life cycle traceability management of roll materials.

2. Key Selection Points For Core Equipment

The following equipment must be carefully considered during procurement:

1) Roll Sheet Rack System

Requirements:

- Load Capacity: 5–30 tons

- Anti-roll design

- Anti-deformation pallets

Common Structures:

- V-type pallets

- Saddle-mounted pallets

2) Stacker Cranes

Key Parameters:

3) Conveying Systems

Common:

- Chain Conveyor

- Roller Conveyor

- Turntable

- Lifting Platform

4) Roll Material Clamping

Common Types:

- C-type Lifting Grippers

- Electromagnetic Lifting Grippers

- Hydraulic Clamping Grippers

5) Automatic Identification Systems

Identification Methods:

- Barcode

- RFID

- Laser Scanning

3. Metal Coil Automatic Storage System Safety Design

Due to the heavy weight of the roll material, safety must be the top priority.

Key Safety Configurations:

1) Anti-rollover Design

Shelving Requires:

- V-shaped Supports

- Anti-roll Blocks

To prevent roll material from rolling off.

2) Equipment Collision Protection

Including:

- Laser Collision Protection

- Limit Protection

- Buffer Devices

3) Overload Protection

Equipment Must Be Equipped with:

- Load Detection

- Alarm System

4) Human-Machine Isolation

Automated storage must include:

- Safety Fences

- Light Grid Protection

- Emergency Stop System

Automated systems are typically equipped with anti-collision, weight detection, and safety monitoring protection mechanisms.

4. Performance Evaluation Indicators

The following indicators are recommended for evaluation during procurement.

Automated warehousing can save approximately 40-70% of storage space compared to manual stacking.

5. Investment Cost Structure

The price of a roll material warehouse mainly consists of five parts:

- Rack structure

- Stacker crane

- Conveying system

- Software system

- Installation and commissioning
