Wooden transport crates remain one of the most commonly chosen solutions in logistics, export, and warehousing. For years, they have been an essential part of supply chains—from transporting industrial machinery and equipment to exporting electronics, metal components, or delicate precision products. Depending on the type of cargo and transport route, different structural materials are used—solid wood, plywood, and OSB boards.
In this study, we present a detailed comparison of two of the most popular types of industrial crates—plywood + wood and OSB + wood. We discuss their technical properties, advantages and disadvantages, physical parameters, and applications in domestic and international logistics. The article also covers phytosanitary requirements under ISPM 15 / IPPC as well as economic and environmental aspects of production.
The role of transport crates in logistics and industry
Transport crates are a key element in protecting cargo during transport and storage. Their primary function is to protect goods against mechanical damage, moisture, dirt, and external factors. A well-designed crate not only protects its contents but also enables safe stacking, securing, and easy handling with forklift trucks.
Modern transport-crate designs combine the durability of wood with the functionality of engineered sheet materials. Using plywood or OSB boards makes it possible to reduce packaging weight while maintaining adequate stiffness—directly improving transport efficiency and logistics costs. Therefore, the choice of structural material is one of the key design criteria.
Materials used to manufacture transport crates
The basic raw material for transport crates is wood—in the form of solid timber, plywood, or OSB boards. Each material has a different structure, physical properties, and applications. Selecting the right option depends on cargo type, load requirements, environmental conditions, and the transport route.
Solid wood
Solid wood—most often pine or spruce—is used in constructions intended for transporting heavy loads such as machinery, steel components, or bulk materials. It features high compressive and impact strength and resistance to deformation. However, it requires proper drying (below 22% moisture content) and heat treatment if the crate is to be used in international transport.
Plywood
Plywood is a layered material made of thin wood sheets (veneers) bonded under high pressure. Its key advantages include low weight, high mechanical strength, and resistance to cracking. Thanks to its uniform structure, plywood offers predictable physical properties and handles dynamic loads very well. In waterproof versions (e.g., birch plywood with phenolic resin), it performs excellently in sea and air transport.
OSB board
OSB (Oriented Strand Board) is produced by pressing layers of long wood strands with synthetic resins. It features high stiffness, resistance to crushing, and dimensional stability. It is an economical alternative to plywood, often used in domestic transport, warehousing, and packaging for lower-load applications. OSB-3 and OSB-4 provide increased moisture resistance.
Comparison of plywood and OSB properties
Plywood and OSB have different technological properties that affect their behavior in transport conditions. The table below compares key physical parameters:
| Parameter | Plywood | OSB board |
|---|---|---|
| Density [kg/m³] | 600–700 | 580–650 |
| Bending strength [MPa] | 40–60 | 25–35 |
| Moisture resistance | Very good (waterproof phenolic plywood) | Good (OSB-3, OSB-4) |
| Dimensional stability | High, no deformation | Medium, slight waviness possible |
| Self weight | Low | Slightly lower than plywood |
| Impact resistance | High | Medium |
| Surface aesthetics | High (smooth, veneered surface) | Medium (visible strand structure) |
| Production cost | Higher | Lower (economical solution) |
As shown, plywood offers better strength and visual parameters, while OSB is more economical and sufficient for most standard applications. In industrial practice, the choice between these materials depends on the balance between cost and required durability.
Technical construction of transport crates
Regardless of the material used, a transport crate consists of several basic structural elements:
- Base – the load-bearing part of the crate, often in the form of a pallet or wooden frame, enabling forklift transport,
- Side walls – made of OSB boards or plywood, reinforced internally with battens or steel angles,
- Top cover – solid or removable, protecting the contents,
- Reinforcements – steel corners, battens, angles, or frames made of solid wood,
- Closures – latches, bolts, transport locks enabling repeated access to the interior.
Modern systems such as PLIBOX or PLITEC enable quick assembly and disassembly without specialized tools. As a result, crates can be folded, transported, and stored in a collapsed form, reducing warehouse space requirements.
Plywood + wood crates – lightness and strength
Transport crates made of plywood and wood combine low weight, aesthetics, and durability. Their structure is based on a rigid pine or spruce frame with multi-layer birch, alder, or pine plywood sheathing. This combination ensures high resistance to pressure, shocks, and changing weather conditions.
Advantages of plywood + wood crates:
- low self weight – lower transport costs,
- high resistance to mechanical damage,
- heat treatment possible (IPPC / ISPM 15 certification),
- attractive appearance – ideal for premium and export goods,
- suitable for sea, air, and road transport.
These crates are particularly popular in export logistics, where low packaging weight and a professional appearance matter. They are often used for transporting electronics, measuring equipment, and high-value components.
OSB + wood crates – an economical and durable solution
Crates made of OSB boards and wood are more economical while still providing high mechanical resistance and structural stability. The core is a solid-wood frame, and the sheathing is OSB-3 or OSB-4. Thanks to this design, the crates are light, durable, and withstand intensive use well.
Advantages of OSB + wood crates:
- lower production cost compared to plywood,
- resistance to crushing and cracking,
- good thermal and acoustic insulation,
- reusable in multiple cycles,
- ideal for warehousing and domestic transport.
In practice, OSB crates are widely used for transporting machine components, metal products, construction goods, and industrial equipment. Thanks to simple assembly and modular construction, they are also a good fit for logistics and warehousing operations where efficiency and durability at a low unit cost are key.
Applications of transport crates across industries
Thanks to high design flexibility and the ability to meet technical requirements, plywood and OSB transport crates are used across nearly every industrial sector. A variety of dimensions, wall thicknesses, and protection options makes them suitable for road and rail transport as well as sea and air logistics.
Most common industries using wooden crates:
- Machinery industry – transport of heavy parts, steel components, and engines.
- Automotive – export of car parts, injection molds, and production-line components.
- Electronics and automation – protecting precision devices against shocks and moisture.
- Logistics and forwarding – crates for packing and distributing oversized cargo.
- Aviation and maritime industries – lightweight packaging resistant to corrosion and changing weather conditions.
- Art and exhibition – transport of artworks, exhibits, and delicate items.
Transport crates are therefore a versatile solution that can be adapted to the specifics of any cargo. With different constructions—from modular models to reinforced full crates—it is possible to achieve an optimal balance between weight, load capacity, and cost.
IPPC certification and ISPM 15 requirements
Any transport crate made of wood or wood-based materials intended for international transport must meet the requirements of ISPM 15 (International Standard for Phytosanitary Measures). This standard defines how wood must be treated to prevent the spread of pests and plant diseases.
The most common process is heat treatment (HT), where wood is heated to at least 56°C for a minimum of 30 minutes. An alternative—now less common—is methyl bromide fumigation (MB). Each product treated in this way receives the IPPC mark—burned or stamped—with the country code and producer number.
At EPALART, all export crates are manufactured in accordance with ISPM 15 requirements and bear the IPPC mark, enabling smooth international trade—both within the European Union and beyond.
Production process and quality control
Manufacturing transport crates requires precision and strict adherence to technical parameters. At EPALART, each stage is supervised and documented to ensure repeatability and structural safety.
Stages of transport-crate production:
- Technical design – defining dimensions, load capacity, material type, and cargo securing method.
- Material selection – choosing plywood, OSB, or solid wood according to the crate’s purpose.
- Cutting and assembly – performed using CNC machines to ensure precise fit.
- Phytosanitary treatment – kiln drying or HT heat treatment in compliance with IPPC.
- Quality control – checking dimensions, stiffness, and correct marking.
Each crate is tested before leaving the facility for tightness, load capacity, and structural stability. For export crates, documentation confirming ISPM 15 compliance is provided, and—if required—a heat-treatment report.
Custom crates and personalization
More and more companies choose custom-designed crates tailored to the specific shape and weight of the cargo. Personalization includes not only dimensions but also internal fittings and external markings.
The most common personalization options include:
- steel reinforcements and protective angles,
- transport handles and cargo tie-down points,
