Cold storage environments (typically -18°C to -25°C) place much higher demands on racking systems than normal warehouses. The challenge is not just whether the racking can be used, but whether it remains safe and durable over long-term operation.
At Shitong Racking, we approach cold storage projects from a structural engineering perspective rather than simply supplying standard racks.
Why Q355 Steel is Essential for Cold Storage
One of the most critical factors is material selection.
Compared with Q235 steel, Q355 steel provides:
- Higher yield strength (≥355 MPa)
- Better toughness under low temperatures
- Improved resistance to brittle failure
In cold environments, steel can become less ductile. Using Q355 significantly reduces structural risk and improves long-term reliability. That’s why we commonly recommend Q355 for cold storage projects.
Key Design Considerations
1. Corrosion Protection
Cold storage often involves high humidity and condensation. Without proper treatment, corrosion can occur quickly.
Typical solutions include:
- Thick powder coating
- Hot-dip galvanizing for higher-end applications
2. Structural Safety Margin
Due to low-temperature impact on material performance, we increase safety factors:
- Thicker uprights (e.g., from 2.0mm to 2.3mm+)
- Reinforced beam capacity
3. Reducing Labor Inside Cold Rooms
Operating inside cold storage is inefficient and costly. Therefore, automation or semi-automation becomes highly valuable.
Recommended Racking Systems
Shuttle Racking System
- Storage density: up to 80–90%
- Reduces forklift entry into cold rooms
- Improves efficiency and lowers energy loss
Drive-in Racking
- High-density storage (up to 85%)
- Ideal for large-volume, low-SKU goods
Why Choose Shitong Racking
- Standard use of Q355 material for cold storage
- Engineering-based structural design
- Support with load calculations and layout planning
- Integration with shuttle or automation systems
We don’t just supply racking — we design systems that perform reliably in extreme environments.
