If you have a scrapyard or a construction resale shop near you, repurpose some old pipe into a sturdy shade and support structure for your garden or patio. Pipe arbors are strong enough to support heavy grapevines, gourd, cucumber, squash and melon vines. Convert your pipe arbor into a greenhouse for winter gardening once you harvest your grapes and other produce for the season.

Pipe arbors are durable and strong.

Connect the Pipes

...
The tee fitting in this photo connects the straight pipe with the elbows.

Step 1

Screw a female tee fitting onto each end of one of the 2-foot long pieces of threaded black-iron pipe.

Step 2

Screw a 2-foot piece of black-iron pipe into the ends of each female tee. Screw one more female tee onto the end of one of the black-iron pipes you just added. Screw a fourth 2-foot piece of black-iron pipe into the third female tee. You should now have four pieces of 2-foot long, black-iron pipe connected by three female tees.

Step 3

Repeat to connect the other four pieces of 2-foot-long black-iron pipe, using three black-iron female tees.

Step 4

Screw a 90-degree, female side-outlet elbow onto the ends of each set of four pipes that you connected in previous steps. A side-outlet elbow looks like a female tee whose arms have been bent into a 90-degree angle. 90-degree side outlets are used to join square or rectangular three-dimensional structures.

Step 5

Screw the 8-foot pipes into the open ends of each side-outlet elbow to make a square, with the four remaining open ends of the elbows pointing toward the sky.

Step 6

Screw the 10-foot pipes into the open ends of each elbow. Turn the entire assembly upside down to stand on the 10-foot pipes.

Dig the Holes

Step 7

Use wooden stakes to mark the four corners of an 8-foot square on the ground where you want your arbor.

Step 8

Dig 2-foot deep, 12-inch diameter post-holes at the points marked by each stake, using a post-hole digger or a power auger.

Step 9

Move the pipe arbor frame so that the 10-feet-long legs fit into the four post-holes. Have one helper at each leg to help move the frame (to prevent straining a muscle).

Step 10

Back-fill the holes around each leg of the pipe arbor frame with sharp-sided gravel.

Step 11

Mix concrete in your wheelbarrow according to package directions. Fill each hole with concrete and allow to set for three to five days, depending on the weather.
