I have a solution for you, but it is not easy to weld steel to aluminum. The Curt D-Ring Tie Down Anchor # J-705 is made of raw steel. It will not work well to weld on to your aluminum trailer because of the differences in the melting points of these metals. All of our weld-on D-rings are made of steel. A skilled professional welder may be able to weld the # J-705 to your aluminum trailer.

Your best option will be to use a bolt-on D-ring, like the Brophy D-ring Tie Down Anchor # LRB1. Bolt-on D-rings are going to be easier to install on your aluminum trailer than a weld-on anchor. Even bolting two dissimilar metals together can eventually cause corrosion issues, so it is best if the two metals can be isolated so they are not touching. Keep in mind that you will want to secure the D-ring well in order to provide a secure attachment. The floor is the best place to secure these kinds of attachments, because the floor can withstand a greater amount of pull than the walls and wall supports.

Steel can't be welded to aluminum using standard techniques, but it is possible. It would require a skilled, certified welder with some experience in this but it can be done.
