Matrax® Strong Plank Access Mat

Strong Plank steel flooring panels

Tired of traditional wood mats and steel frame rig mats that are bulky and expensive to transport?

How about composite plastic mats that are overpriced and easily damaged?

The Matrax Strong Plank Access Mat steel mats are a unique alternative to wood and composite plastic mats. They offer multiple uses, have a long life span, and are strong but at the same time very light and serviceable.

The Strong Plank mat is versatile, easily installed and removed, and ecologically friendly. The Strong Plank is manufactured from A606 Type 4 self-weathering rolled steel that is considerably more resistant to the degradation and damage that typically occurs with its timber and composite plastic counterparts.
