Cold Storage Shelves Selection and Configuration Guide
1. Material selection standards
Steel and galvanizing
The mainstream is Q235 cold-rolled steel with a yield strength of ≥245MPa. The surface is treated with electrostatic spraying or hot-dip galvanizing. The thickness of the galvanized layer is ≥85μm. It has a salt spray test of ≥1000 hours without rust and is suitable for low temperature environments of -30℃.
Stainless steel (such as 304/316L) is used in high humidity areas and has better corrosion resistance than ordinary steel, but the cost increases by 30%-50%.
Composite materials applications
The lightweight design of the aluminum profile and steel-wood hybrid structure shelf has an empty thickness of only 0.3 meters, and the four-layer stacking storage space utilization rate is increased by 70%;
Fiberglass shelves perform well in acidic and alkaline environments, but their load-bearing capacity is limited to less than 800kg/layer.
2. Structural design and load-bearing specifications
Jarak kolom
The standard spacing is 2.4m, and the seismic structure supports a magnitude 8 earthquake.
GB 50011-2025 seismic code
Single layer load-bearing
Light duty shelves ≥ 200kg/layer, heavy duty shelves ≥ 5 tons/layer
Cold Storage Design Code GB-20259
Manual access area ≤ 12 meters, automated three-dimensional warehouse can be expanded to 30 meters
3. Safety Construction and Maintenance Strategy
Antifreeze design points
The floor needs to be paved with a polyurethane insulation layer ≥150mm thick, and an anti-frost heave heating device should be installed underneath to prevent soil freezing and structural deformation;
The shelf connection bolts use double-locking wedge threads, which are shock-resistant and prevent from loosening in an environment of -30℃.
Operation and maintenance specifications
Check the vertical deviation of the shelf every quarter (≤1/1000) and the horizontal error of the beam is less than 2mm;

Using the EM-R51 triple-proof handheld terminal (IP65 protection/1.22-meter drop resistance) for inspections increases data collection efficiency by 300%.

Warehouse Management System
The WMS system has increased inventory turnover by 30%, with a mis-delivery rate of less than 0.03%, and supports coordinated operations with AGV robots;
Integrated temperature and humidity sensor (accuracy ±0.5°C) to monitor cold storage environment fluctuations in real time.
Energy-saving and efficiency-enhancing technologies
The photovoltaic power supply system covers the shelf operation area, reducing carbon dioxide emissions by 120 tons annually;
The shuttle rack is combined with a four-way forklift to increase storage density by 40% and reduce energy consumption by 25%.
