With the rapid development of smart warehousing, ASRS (Automated Storage and Retrieval Systems) are widely used in manufacturing, logistics centers, e-commerce fulfillment, automotive parts, and many other industries.
As one of the most basic yet critical load carriers in an ASRS system, the plastic pallet directly affects system stability, operational safety, and overall efficiency.
So, how should you choose the right plastic pallet for an ASRS system?
Why Do ASRS Systems Require Higher-Standard Plastic Pallets?
Unlike traditional manual warehouses, ASRS warehouses have the following characteristics:
Fully automated operation, requiring extremely high pallet consistency；
High-bay racking systems, demanding excellent bending resistance and dimensional stability；
Frequent operation with conveyors, stacker cranes, and lifts, requiring high structural precision and durability.
In different industries, cargo packaging, stacking methods, and load specifications vary significantly.
In ASRS systems, the most critical factor for plastic pallets is deformation control.
Under heavy loads, plastic pallets may experience slight downward bending on both sides. This deformation is closely related to load weight and distribution.
If a pallet with insufficient height or rigidity deforms excessively, the fork entry openings become smaller. Standard forklifts may then fail to enter properly, or worse, the fork arms may push the pallet out of the rack, causing serious safety risks.
Therefore, standard logistics plastic pallets are not always suitable for ASRS systems. Specialized ASRS plastic pallets must be selected.
Core Selection Criteria for ASRS Plastic Pallets
Pallet Structure
Plastic pallets can be classified as follows:
By structure type:Three Runner Pallet;Six Runner Pallet;Double-Sided Pallet;Nine-Foot Pallet
By manufacturing process:One-piece injection molded;Welded structure;Assembled structure
By deck surface:Grid deck;Flat deck
Our recommendation
For ASRS systems, stability and safety are top priorities.Nine-foot pallets are the least stable when used on racking systems and should be excluded first.Other structures should be selected based on cargo weight and packaging
Based on current market feedback, Three Runner Plastic Pallets are the most popular choice for ASRS
Dimensional Accuracy & Consistency: More Important Than Load Capacity
In an automated ASRS warehouse, dimensional tolerance is one of the most critical indicators.
Even minor deviations in length, width, or height can cause:
Conveyor jamming;Stacker crane pickup failures;System alarms or complete shutdowns.
Our recommendation
Choose manufacturers using high-precision injection molding machines.
Plastic pallets supplied by Qianhe Plastic are produced using imported KraussMaffei and ENGEL large-scale high-precision injection machines, ensuring:Excellent dimensional stability；High reliability；Up to 99% consistency within the same batch.
Load Capacity: Focus on Rack Load Performance
In ASRS systems, the primary load type is Rack Load, not dynamic load.
Key considerations:Rack Load Capacity；Long-term deformation under static load.
Common market requirements for ASRS rack load:800–1500 kg
Our recommendation
For higher rack load requirements, steel pipe reinforcement is highly effective.Steel pipes can be added to pallet legs and deck，this significantly reduces deformation，extends plastic pallet service life.Steel pipe thickness can be customized to meet higher load demands.
Material Selection: PP or HDPE?
| Material | Characteristics | Suitable Applications |
| PP | High rigidity, excellent dimensional stability | Preferred for ASRS systems |
| HDPE | High toughness, excellent low-temperature resistance | Cold storage ASRS |
Material selection guide:
Standard ASRS warehouses: Choose PP Plastic Pallets
Cold storage ASRS: Choose Modified HDPE or Low-temperature-resistant PP.
Our recommendation
For standard ASRS applications, PP plastic pallets are superior to HDPE pallets.During injection molding, molten plastic undergoes rapid cooling after demolding, which can cause shrinkage or expansion.PP material is more dimensionally stable than HDPE.PP pallets have smaller dimensional deviations.This is critical for automated handling accuracy
Anti-Slip Design Is Essential
In high-speed ASRS operations, pallet anti-slip performance is critical.
Without sufficient friction:
Goods may slide or fall
Serious safety accidents may occur
Our recommendation
The anti-skid material must meet strict ASRS standards:Use TPU double-layer anti-skid pads；Material must be 100% virgin, odor-free；Surface: white, soft, wear-resistant TPU；Bottom layer: hard plastic, firmly bonded to the pallet；Black anti-skid pads (PVC or recycled rubber) are strictly prohibited.
