Might not be a good choice for easily-spooked horses.

Fairly easy to maintain – can be hosed down.     Not suitable for extreme weather – Being a conductive material, aluminum trailers get hot quickly in summers and extremely cold and frigid in winters. This can be uncomfortable for horses during transportation.
Inexpensive – compared to other horse flooring options, aluminum is cheaper to install.Prone to corrosion and rusting – while aluminum is definitely more durable than wood, it can still rot over time. You will need to schedule acid baths to prevent oxidation and rusting.

This can lead to water seepage and drainage and invite rot.

Easy to install – You can easily cut Rumber tiles to size to help fit in a given space. These days, you also get inter-locked tiles that do not need any special tools or adhesives for the setting. You can also replace just the damaged tile instead of changing the entire floor.     The cost of composite material Rumber flooring can be high – expect to shell out at least $1000-$2000 depending on the trailer’s size.
Suitable all-year-round – This material does not transfer heat making it suitable for hot areas too.
