Lifetime .040 #1 grade treated floor with thick stall mats standard - Rumber rubber plank floor also available with 20 year warranty 

Hawk Trailers come standard with Georgia Pacific Southern Gold  #1 Grade pressure treated pine  ( few if any knots, no warped boards) This material is warranted not to rot for as long as you own your Hawk trailer. 

Hawk Trailers wood flooring is more horse friendly than aluminum and actually requires less maintenance. There is less vibration and less heat from the road transmitted up into the horse area. Additionally, in the event that you did need a repair it is easy to accomplish.

Some aluminum floor warranties are void if the owner does not pull out the mats and soap and hose out the trailer after each use.
