🔹 Why Deck Material is Critical

The flatbed deck directly carries and supports the cargo. Its surface affects:

• Grip & protection of cargo
• Load distribution and deck bending
• Weight & payload capacity
• Lifecycle cost & repair frequency

✅ Wood Decks (Hardwood & Tropical Woods)

• High friction → reduced cargo slip risk
• Absorbs shocks & protects delicate loads
• More affordable than steel
• Typical thickness: 28–40 mm

Weaknesses: moisture, rot, chemical exposure → requires regular coating

✅ Steel Decks (Checkered Sheet / High Strength)

• Superior strength for concentrated loads
• Excellent for machinery, forklifts and tracked vehicles
• Can be repaired by welding
• Used with lashing rings and chain hooks

Weakness: Low friction → cargo must be secured carefully

✅ Aluminum Decks

• Lightweight solution → maximum payload
• Corrosion resistance in harsh climates

Weakness: lower abrasion resistance than steel

🔍 Mixed / Hybrid Deck Solutions

Best of both worlds — designed depending on cargo type:

• Steel center zone → forklift tracks & heavy machinery
• Wood side strips → better grip for pallet loads
• Optional steel wheel guides for tracked loads

📊 Detailed Comparison Table

Deck Type	Grip	Durability	Weight	Cost	Typical Use
Wood	⭐⭐⭐⭐⭐	⭐⭐⭐	⭐⭐⭐⭐	Low	Pallet loads, packaging
Steel	⭐⭐	⭐⭐⭐⭐⭐	⭐⭐	Medium	Machines, construction steel
Aluminum	⭐⭐⭐	⭐⭐⭐	⭐⭐⭐⭐⭐	High	General freight
Hybrid	⭐⭐⭐⭐	⭐⭐⭐⭐	⭐⭐⭐	Medium/High	Mixed operations

🛠 Deck Protection & Accessories

• Anti-slip surface paints for steel
• Zinc-coated flooring against corrosion
• Drainage holes for water removal
• Plywood under-layer with steel grid support

🌦 Regional Considerations

• Wet & snowy regions → steel or aluminum preferred
• Hot & dry climates → wood offers long life + grip

🧾 Decision Guide

If main cargo is:

• Machinery & equipment → Steel or Hybrid
• Palletized goods → Wood
• General freight + max payload → Aluminum

Conclusion:
Wood = Grip & cost efficiency
Steel = Heavy-duty durability
Aluminum = Payload advantage
Hybrid = Optimal performance for mixed fleets
