Customer Questions & Answers

What tools do I need to assemble 10' x 20'

Asked by: Waterdawg
An awl, a phillips head screw driver, hammer, string, pliers, an 8 foot ladder, and you'll need at least two extra pair of hands for a couple of hours as you put the trusses together.

How long of a trailer do I need to pick up the 10x20 kit--is 8 feet enough???

Commander 10 ft. x 20 ft. Hot Dipped Galvanized Steel Shed
Asked by: wildyank130
Just received my 10 x 20 shed on 04/07/16 and there were 4 boxes at a total weight of 743 pounds, that's an average 185.75 LBS per box. Some boxes were thicker and heavier than others but all were 80 inches long and about 35 inches wide. They came on a pallet that was long and narrow and not very strong. I think it requires at least two people because you need to keep the boxes flat or the loose parts inside will get damaged.

how big of a platform do i need to put the shed on?

Asked by: ronnie
It is exactly 10' by 20'. I decided to give myself 3-4 inches extra in both length and width.

Commander 10 ft. x 20 ft. Hot Dipped Galvanized Steel Shed is rated 3.6 out of 5 by 14.

Do not try to put this together without an awl, I am very thankful I saw that recommendation by another review. 25 hours to put together is a good estimate (I have 10' by 20'). The directions are relatively easy to follow, there are a few confusing issues, but it isn't that tough. The hardest part of the entire operation is putting together the trusses, believe it or not, screwing the screws into the pre drilled holes is very difficult (you can forget using a power drill) and left my hands in blisters. Worst part was that there were numerous parts missing. I had two key parts to one truss missing, plus a few other parts that I was able to replace with stuff I bought at Home Depot. This dropped my review significantly. Best part was the price, easily half the cost of similar sized sheds sold at Home Depot in the store. I put my shed on a concrete floor 4-6 inches thick. Probably the hardest part of the whole job.

Takes a long time to build. 4. Dents easily. 5. Doors are a joke. 6. Can be built stronger for half the price with 2X4 construction, and steel siding material. Also would take half the time. 7. Save your money here, try something else.

Very flimsy metal, buckled easily under its own weight not enough support in middle of structure, roof ridge bowed down - The whole thing needs to be made of stronger steel - posts, roof rafters, and walls also should be thicker

Rated 5 out of 5 by from Awesome. This isn't a cheap tin shed. It was a lot of work. 84 man hours. Get some help. If you are not good at interpreting and following directions, get a lot of help. Make sure that your base is level, or the building will tweak, and it will be hard to line up the holes. Common sense. The end result is well worth the effort. I think it is a great value for the buck. And it looks great. Would do it again. Recommended for those looking for a longer lasting quality shed.

Rated 2 out of 5 by from way over priced 20 foot shed This shed takes 2 men 3 to 4 days to build--many of the holes didn't line up--your base must be perfectly level--it is made of a very weak metal--if you lean on it or your kids hit it with a ball, it dents--buy a wooden shed--it will last longer and be more secure

Rated 5 out of 5 by from Easy to assemble I needed a shed to enclose my well pump equipment but I decided to make it bigger. I chose the Arrow 10 x 20 foot shed. The instructions are clear and concise, amazingly accurate. Every hole lines up with a little help from an icepick. The hardware is lacking gripper nuts but a bent open end wrench and power screwdriver are helpful. A few days are needed to complete the shed. Time will tell how the shed holds up to the weather but I am pleased with the purchase.

Rated 5 out of 5 by from What a cool economical way to have a large shed. It took a little work, but well worth it. A much larger shed than we could have gotten in a wood shed for the price.

Rated 3 out of 5 by from What a pain to assembly Ok once assembled this building is nice so the three star rating is because of assembly. For the 10x20 their is 4 truss assembly's you must put together which each have 22 pieces each. This thing is like a large erector set and is a pain to put together. The hardware you get is cheap screws you get for the roof is small screws with plastic washers you must put on every screw. I opted not to install those in my roof because the plastic will crack over time in the sun and leak. I used self tapping sheet metal screws with rubber gaskets for a better seal. Pre drilled holes don't all line up so it makes it harder. One piece of advice I have is to ensure you are level and square during the whole assembly process. I would also consider the assembly time which took two of us 2 1/2 weekends and look at a wood model yes more expensive but would be so much easier to put together. And yes we both know about construction. The only way I would suggest this product is if you only bought the 10x10 because the larger you go like the one I bought the 10 x 20 you get two 5 foot expansion modules and the holes and extruded pieces are not exactly the same probably due to poor QA during manufacturing I hope this review informs you of what to expect with this building and if size vs cost is you main consern as it was for me than this may be for you just be prepared for some labor and irritation.
