How to Fix Sagging Soccer Goals: Tips and Tricks

AI Thread Summary
To address the sagging soccer goal made from 4-inch drainage pipe, several solutions are proposed. One suggestion is to saw off the ends of the crossbar, rotate it 180 degrees, and use couplings to create an upward bow that will eventually level out. Another idea involves placing a support under the center of the crossbar when not in use to create a reverse sag. Additionally, reinforcing the structure with a 2x4 or metal pipe could help stiffen the goal. The goal serves dual purposes for practicing shooting and goalkeeping, and it needs to be movable for maintenance.

A few years ago I built a soccer goal for my son out of 4 inch drainage pipe. It is regulation size which I believe is about 24 ft long and 8 ft tall. It has served okay for his practices but the top crossbar has started to Sag due to the long expanse 24 feet. Any easy or ingenious way to fix the sagging? Like a guy wire or something? I don't have a tree or anything to attach it to so it needs to work with just the goal itself. Any help is appreciated!

Or replace the horizontal pipe which worked for a while or just prop up the middle with some wood? Is the goal for practicing shooting on goal or practicing being a goalie? Do you need to move it?
 
Can you stuff a 2x4, metal pipe or something similar through the tube to straighten and stiffen it?

Two ideas:
1) Saw it off near the ends, rotate 180 degrees, then add a coupling at each end. It will now bow upwards and gradually sag to level.

2) Shove a support under the middle whenever it is not in use. Make the support long enough to bow it upwards far enough to start developing a reverse sag.
 
Here's a video of a miniature goal but it has an interesting bar feature that could support your 24 ft bar.

Its for both. I do need to be able to move it to mow around it...
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
