In modern chemical enterprises, how to achieve safe and efficient storage of bulk materials remains a core challenge in warehouse management. Particularly when it comes to storing entire pallets of various chemical raw materials—such as liquid drums or powdery/granular substances—traditional conventional shelving systems often struggle with issues like insufficient load capacity, narrow operational aisles, and inadequate safety protection. As professionals deeply rooted in the warehousing equipment industry, we recommend adopting a贯通式 industrial shelving system—a robust storage solution specifically designed for high-density, full-pallet storage, which is rapidly becoming the ideal choice for the chemical industry to enhance both storage efficiency and safety.

Why do chemical raw materials prefer "through-type" storage?

Unlike the small-item sorting scenarios in daily goods warehouses, chemical raw materials are typically handled in bulk using standard pallets (1.2m × 1.0m) for efficient turnover. The unique advantage of through-type racking lies in its "rail-style" continuous storage design—by eliminating the traditional upright columns that block horizontal beams, it creates unobstructed longitudinal aisles, allowing forklifts to directly enter the rack structure to pick up or put away entire pallets. This innovative design delivers three key benefits:
✅ Ultra-high space utilization: A single level can support up to 2–3 tons per pallet, and the layer height can be customized according to cargo dimensions, increasing vertical space utilization by more than 30% compared to conventional beam-type racking systems.
✅ Dense storage feature: Only a forklift passage width (approximately 2.5–3 meters) needs to be reserved between adjacent racking units, significantly reducing the area occupied by ineffective aisles;
✅ Advanced-first-out mode offers strong adaptability: It’s particularly well-suited for scenarios involving large-scale, single-product turnover, reducing the frequency of inventory transfers and minimizing the risk of material confusion.

Key Points for Specialized Safety Design in Chemical Engineering Scenarios

Chemical raw materials are characterized by strong corrosiveness, flammability and explosiveness, as well as the tendency to release harmful volatile gases—features that place stringent demands on the corrosion protection, fire safety configurations, and environmental adaptability of shelving systems. In our project, we have identified the following key protective measures:

🔹 Material Upgrade: Corrosion Resistance + High Strength—Double Protection
- The main components are made from high-quality Q235B steel, with a surface treated through acid pickling and phosphating followed by three-layer electrostatic spraying for robust protection against most acidic, alkaline, and salt-spray corrosions.
- For highly corrosive media (such as concentrated sulfuric acid and sodium hydroxide solutions), we recommend using the hot-dip galvanizing process or 304 stainless steel material;
- Anti-slip textured steel plates have been added to the bottom of the shelves to prevent pallets from slipping due to moisture.

🔹 Building a Fire-Resistant Isolation System
- Eye-catching warning signs are placed at both ends of each shelf, clearly designating the fire-prohibited area.
- Install temperature and smoke detectors with interlocked automatic sprinkler systems;
- Shelf spacing complies with the "Code for Fire Protection Design of Buildings," ensuring that the main aisle is at least 4 meters wide and auxiliary aisles are no less than 2.5 meters wide, thus guaranteeing smooth emergency evacuation routes.

🔹 Dynamic Load Monitoring Mechanism
- Accurately calculate the rated load for each layer based on differences in chemical densities (such as resin particles versus liquid ton bags), and clearly label the columns with warning signs.
- Regularly use an infrared rangefinder to check the verticality of shelves, preventing structural deformation caused by prolonged heavy loads;
- Special areas are equipped with anti-collision corner guards to prevent forklift operation errors from causing tipping hazards.

Typical Application Case Analysis

A certain pesticide manufacturer once faced this issue: the existing warehouse had to store more than 500 IBC ton containers along with hundreds of cartons of bagged adjuvants. The traditional flat stacking method resulted in severe congestion of aisles, and some moisture-sensitive raw materials even began to clump together due to dampness at the bottom layers. After introducing贯通-style racking systems:
✔️ Partition Management: Place moisture-sensitive materials on the upper level, and heavy liquids on the lower level, leveraging the shelf’s built-in slope to enable natural drainage.
✔️ Intelligent Dispatch: By using the WMS system to label each storage location with attribute tags, forklift drivers can simply scan the code to instantly access the optimal pick-up and put-away route.
✔️ Cost reduction and efficiency boost: After the renovation, storage capacity increased by 45% for the same area, picking efficiency improved by 60%, and the annual loss rate was reduced to below 0.3%.

Mandatory Checklist Before Implementation

| Project | Verification Content | Notes |
| Ground Load Capacity | Confirm floor load ≥ 8 kN/㎡ | Weak foundation requires reinforcement |
| Product Specifications | Maximum Pallet Dimensions and Weight | Oversized/Overheight Goods Require Custom Non-Standard Components |
| Fire Safety Inspection | Ensure sprinkler heads cover all storage areas | Prohibit obstructing fire safety equipment |
| Personnel Training | Assessing Forklift Drivers' Narrow-Aisle Driving Skills | Strictly Prohibit Sudden Braking and Sharp Turns |

Safety is always the primary driving force.

     For chemical enterprises, a good warehousing solution is by no means simply a matter of piling up hardware—it requires comprehensive consideration across multiple dimensions, starting from the characteristics of the materials and integrating architectural structures, operational processes, and emergency management. Through-type racking systems, with their efficient space management and flexible configuration capabilities, provide a reliable platform for storing chemical raw materials on full pallets; however, this depends entirely on the strict implementation of standardized construction practices and regular maintenance schedules.
