These in my opinion are the best cattle guards on the market. The main beam supports are on two foot centers where most others are on three foot centers. The pipe on top have thirteen piece were others have twelve pieces. The price is the best price around that I know of. Especially for the quality of what you are getting. The weight of a cattle guard is a good indicator of the cattle guard. The lighter the cattle guard the lighter weight of the metal used to make it.
