The Strongest Construction Mats in the World

MegaDeck® HD Supports the Heaviest Loads Over the Toughest Terrain in the Most Challenging Environments. MegaDeck® HD composite matting is the strongest, best engineered interlocking panel system on the market today. MegaDeck HD, heavy-duty composite mats are designed specifically for high-traffic work sites, such as power transmission, oil rigs, and construction sites. MegaDeck HD creates a stable platform or portable roadway anywhere in the world, regardless of climate or terrain.

MegaDeck®HD Provides Solutions for:


Save time and money with Signature’s high-quality composite mats.

  • Faster installation times compared to wood mats
  • Composite mats last up to 10 years
  • 12 inch flange guides mats into place
  • Quick lock-and-go connections
  • Save time and money on shipping with more mats per truckload than 3-ply wood mats
  • Protect your equipment and minimize wear and tear


Innovative Engineering Design for Superior Performance and Durability

MegaDeck HD construction mats are manufactured in the United States using a proprietary blend of High Density Polyethylene (HDPE) and special impact modifiers to accommodate thermal expansion, UV resistance, anti-static properties, and tremendous strength. A unique process ensures all plastic is completely melted then molded, preventing micro-fissures and inconsistencies. A hollow ribbed interior provides superior performance over soft ground with a low California Bearing Ratio (CBR).

The world’s strongest construction mats are fully modular and can be interconnected in multiple directions to form large work areas, passing lanes, turns, and a variety of other platform and roadway configurations. These rugged composite mats will not rot, degrade, or warp, which allows for long-term installations and many years of reuse.

MegaDeck HD is the most advanced engineering construction mat in the world.

Superior Weight-Bearing Capacity – MegaDeck HD composite mats have a weight-bearing capacity of up to 600 psi / 86,400 lbs. per sq. ft.

Non-Conductive – MegaDeck HD composite materials are inert, providing a non-conductive safe working platform.

Strong Support Structure – MegaDeck HD’s cross-ribbed interior distributes weight across the entire panel. These mats are not intended for bridging.

Better than Wood – Unlike plywood, MegaDeck HD will not warp, rot, crack, or delaminate, and contains no unsafe chemicals.

Maximum Shipping Efficiency – MegaDeck HD mats are properly sized to easily ship 40 mats in standard ISO containers and flatbed trailers.

Effective Inventory Control – Each MegaDeck HD mat is marked with a unique serial number, making inventory control easier. RFID chips are incorporated into the core of every mat during the manufacturing process for fast, efficient scanning.

Easy Cleaning – MegaDeck HD mats can be cleaned using a high-powered pressure washer. Most commercial cleaning agents will not damage the surface, but consideration should be given to environmental concerns.

Compatible with Other Composite Mats – MegaDeck HD mats are 100% compatible with the original MegaDeck mats and can be used with other composite matting products.

Flammability Resistance – UL-94 HB Rating.
