What is Container Flooring?

Container Flooring Plywood is a type of high-strength plywood specially designed for manufacturing container floors, classified as a special industrial plywood. The main difference between it and ordinary plywood lies in its strength, durability, and resistance to harsh environments.

Features

High Load-Bearing Capacity:
The payload of containers, whether 20GP or 40HQ, is around 28 tons net weight. The load per square meter needs to be 1–2 tons, but in practice, the higher design standard is required. Commonly, container floors are designed to withstand 1.8–2.5 tons/m².
Premium Raw Materials:
Hardwood, such as keruing wood, is often used as the core material. Its dense fibers ensure strong bonding between layers, excellent compressive and wear resistance, meeting the heavy load and durability requirements of containers.
Waterproof Adhesive:
Phenolic glue is used for hot-pressing, providing excellent water, moisture, and weather resistance, ensuring the plywood does not delaminate or lose adhesion under high temperature, humidity, or salty conditions.
Wear and Corrosion Resistance:
The surface is treated for anti-slip, increasing friction to prevent cargo from sliding, while also offering resistance to corrosion and abrasion.

What Type of Hot Press is Suitable for Container Floor Plywood?

High Pressure (1500 tons)

High Density – Strong pressure ensures deep glue penetration and tight core bonding, eliminating voids or bulging.
Uniform Thickness – Heavy boards (28mm) are pressed flat and stable, meeting strict international standards.
Superior Strength – Significantly improved bending and compressive strength, capable of bearing forklifts and heavy cargo,this is essential for container floor plywood.
Long-Lasting Durability – Reduced internal defects mean better wear, impact, and moisture resistance for extended service life.

Multi-layer Pressing (25 layers / 26 hot plates)
- High Output Efficiency
  25 openings allow multiple thick boards (≈28mm) to be pressed at the same time, ensuring large-scale and stable production capacity.
- Consistent Quality
  With 26 hot plates, every layer receives even heat and pressure, guaranteeing uniform curing of glue and stable bonding across all boards.
Plate Size 2700 × 1370 mm (double in & double out)It can ensures each plywood receives uniform heat and pressure, which is critical for thick, multi-core flooring to avoid delamination or warping
Plunger Cylinders (8 pcs) + Multi-point Hydraulic SystemMulti-cylinder distribution guarantees even pressure. Container flooring boards are thick and dense, and multiple cylinders ensure safe pressing, preventing “local underpressure” that could lead to middle looseness or edge delamination — a critical feature for container flooring production.
Stroke 1800 mm / Accommodates Thick Stacks
- Container floors are much thicker than ordinary plywood (≈28mm) and often require multiple core layers,the stroke of 1800 mm allows the press to accommodate very thick stacks, ensuring all layers are pressed simultaneously.
- Large stroke combined with multi-layer pressing ensures uniform pressure across all layers, even in thick stacks, preventing delamination.
Hot Plate Thickness & Rigidity (Plate thickness 52 mm; Upper/Lower beams 1000 mm, precision planed)
- High rigidity prevents bending or deformation under high nominal pressure (1500 tons),Maintains consistent pressure across the entire panel, critical for heavy-duty flooring
- Container floors are thick,Thick, rigid hot press plates and beams ensure the press can handle multi-layer stacks without sagging, ensuring strong, reliable panels.
High-speed Closing & Controllable Process (35 s closing time + fully automatic control system)
- Rapid platen closing reduces cycle time, increasing production efficiency.
- Automatically monitors and controls pressure, temperature, and pressing time for each layer,Ensures consistent curing of glue and uniform board density, reducing defects like delamination, bulging, or uneven thickness.
Hydraulic Flow / Pump & Power Configuration (Low-pressure & High-pressure pumps)
- Essential for thick or multi-layer boards (e.g., 25-layer container flooringallow low-pressure pumps allow gradual pressure increase, ensuring glue penetrates every layer,which is essential for thick or multi-layer plywood boards (e.g., 25-layer container flooring.
- High-Pressure Pumps Prevent middle layer looseness or edge delamination,Ensure board density and load-bearing capacity
- Dual Pump & Motor System Provide stable oil supply, fast response, and sufficient power for continuous high-load operation
Frame & Structure (45 mm steel split double-frame, ~76 tons total weight)
- Supports Large & Thick Panels,suitable for container floors (≈28 mm × 2700 × 1370 mm),and can handle multi-layer stacks without sagging
- Rigid frame reduces vibration, extends equipment lifespan, and ensures consistent, high-quality production
