Batting Cage Steel Tubes - What size do I use

[No_Diva]

I am building a batting cage in my backyard. The cage will be 12x12x70. I'd like to use 4 steel posts. The posts will be 4 feet into the ground. I was considering using 4 x .120 A500/A513 post and cable. Can the posts handle the load? I believe the net weighs about 140 lbs.

Welcome to PF, fun project.

How many pairs of posts are you planning on for the 70' length? What kind of structure will be along the tops of the posts to support the net? Are there any wind loading or rain/snow loading considerations?

Can the posts handle the load?

The answer to that question can be found by looking at batting cages in your area. Use someone else's knowledge at the cost of a small amount of vehicle fuel.

Are there any wind loading or rain/snow loading co

I'd think that would be the most relevant factor - plus the effect of flying debris during storms and possibly the build up of wet leaves in autumn. Again, studying existing structures would be valuable.

The cage will be 12x12x70. I'd like to use 4 steel posts.

Just 4??? I re-read this and I assumed there would need to be a lot of guy lines to give it strength. Will you have room for the guys (at the side and at the ends)? A 70' span will involve a lot of tension to keep it from sagging badly (unless it is spider's web).
More spars and some 'triangles' in there would avoid needing to go 4' down. I'm further convinced that you need to be looking around you at what people tend to use. Are kits available - not to buy but to study?
