Amazon Metal Sheds assembly
Jaxsunny, Aiho, Thanaddo, Build-Well, Lausaint Home: the same shed, different names.
These interchangeable marketplace brands are all the same generic galvanized-steel kit from the same kind of factory, so they build the same way. Get the panel orientation right, understand that the floor is a frame not a floor, and seal the screws, and any of them goes together fine.
One kit, a dozen names
Search for a cheap metal shed online and you will meet a rotating cast of brand names, Jaxsunny, Aiho, Thanaddo, Build-Well, Lausaint Home, and many more. In practice they are the same product: a galvanized-steel, apex or sloped-roof flat-pack shed, often with a faux wood-grain finish, sold under whichever name the seller has registered. The parts, the instructions and the quirks are effectively identical.
That is good news, because it means one set of techniques works for all of them. These are genuine value, owners routinely say the finished shed looks like a far pricier model, but they are thin-gauge metal built from many small panels and a great many small screws, and they reward patience and a few specific habits.
The rest of this guide is those habits. They apply whether the label on your box says Jaxsunny, Aiho, Thanaddo, Build-Well, Lausaint Home or any of the near-identical alternatives.
The build
Thin panels, many screws, two people. Budget most of a day.
| Model | Time | People |
|---|---|---|
| Small (4x6, 5x3)Fewer panels, same method. | 4 to 6 hours | 2 |
| Walk-in (6x8, 8x8, 9x6)The famous "8000 screws." Take your time. | 8 to 20 hours | 2 |
| Level base firstNo floor included. Timber or concrete, level. | half a day | 1 to 2 |
| Fitting a plywood floorOnto the steel floor frame. Plywood not included. | 1 to 2 hours | 1 |
| Sealing and anchoringSilicone the roof screws; anchor the light box. | 1 hour | 1 |
The instructions are almost always wordless pictograms, so study each diagram closely, and lay out and identify every panel before you start.
What works on any of these sheds
Panel orientation is everything, so check it before every screw
The single most important habit. On these kits, if the pre-punched holes do not line up, it is almost never a manufacturing fault, it is that a panel is the wrong way round or in the wrong place. Owners are unanimous: pay close attention to the orientation of each panel against the diagram, because one panel installed backwards throws off everything after it. Dry-check each panel before driving screws, and if holes suddenly stop aligning, stop and re-check the last piece rather than drilling new holes.
The floor is a frame, not a floor, so buy plywood
A near-universal surprise. These sheds are advertised with a floor, but what that means is a steel floor frame, not a finished floor. Owners regularly discover that with flooring means metal framing, and that there is no surface to stand on. So plan to buy and cut plywood to lay on the frame, which also stiffens the whole shed and gives you something to anchor to. Budget for the plywood before the shed arrives.
Seal the screws, because there are never enough washers and the metal rusts
A recurring, sourced fix. These kits routinely ship with too few plastic washers, especially for the roof panels, and the steel is thin and cheap enough to rust at the fastenings. The remedy owners land on is to run clear silicone over the screws, particularly the roof screws, which both makes up for missing washers and seals the penetration against rust and leaks. Do it as you assemble the roof while it is easy to reach.
Expect wordless instructions, mislabeled panels and mixed revisions
Set your expectations for the paperwork. The instructions are picture-only, and owners report panels that are mislabeled, and even kits that mix parts from different design revisions, so a trim piece or the apex cap may not quite match the diagram and needs a little shaping. None of this is fatal, it just means working slowly, trusting the physical fit over the label when they disagree, and being ready to gently adjust a part rather than forcing it.
Wear gloves, because the thin metal is sharp and bends easily
The panels are thin-gauge and their edges are sharp, so cut hands are the most common minor injury on these builds. Wear snug work gloves throughout, and handle the panels carefully because they bend easily, a panel creased during assembly stays creased. Minor shipping bends can usually be worked flat by hand before they go on.
Build on a level base and anchor it, because it is a lightweight box
Like any thin-metal shed, these need a flat, level base, timber or concrete, both because the panels only align on level ground and because there is no floor of their own. And once built they are light, so they catch wind badly, anchor the shed to its base or an adjacent wall. Inspect the kit against the parts list on arrival too, since missing hardware is a common complaint and the sellers generally resolve it within a day if you flag it early.
Before you build
Prepare a level base of timber or concrete, since none of these include a floor.
Buy plywood to lay on the steel floor frame, and exterior silicone for the screws.
Set aside most of a day, and a second pair of hands, for the many small panels and screws.
Have snug gloves for the sharp edges, and check the kit against the parts list on arrival.
And plan to anchor the finished shed, because a light metal box blows around.
Where an installer helps
By getting the panel orientation right the first time, which is the difference between a smooth build and a frustrating teardown, and the single thing that trips up most DIY builders on these kits.
By preparing a level base and fitting a proper plywood floor on the frame, neither of which comes in the box.
By sealing the roof screws against the rust and leaks these thin-metal sheds are prone to, and anchoring the light structure against wind.
And by working efficiently through the wordless instructions, the mislabeled panels and the many screws. These are genuine value once built well, and the value of help is in turning a fiddly budget kit into a square, dry, solid shed.
What an installer does
- Identifies and orients every panel correctly against the diagram before fastening.
- Builds a level base and fits a plywood floor on the steel frame.
- Assembles the panels, walls and roof square, handling the sharp thin metal safely.
- Seals the roof screws against rust and leaks, making up for missing washers.
- Anchors the lightweight shed to its base or a wall against wind.
- Checks the kit for missing hardware on arrival and adjusts mismatched trim pieces.

Questions people ask
Are Jaxsunny, Aiho, Thanaddo, Build-Well and Lausaint Home the same shed?
Effectively, yes. They are the same generic galvanized-steel flat-pack shed sold under different marketplace names, with the same parts, the same wordless instructions and the same quirks. Whichever name is on your box, the assembly techniques in this guide apply.
Why don’t the holes line up?
Almost always because a panel is oriented the wrong way or in the wrong position. On these kits the pre-punched holes are accurate when the panels are correct, so if holes stop aligning, re-check the last panel against the diagram rather than drilling new holes. Panel orientation is the thing to watch on every step.
Does it come with a floor?
No, it comes with a steel floor frame, not a floor. The listings say with flooring, but that means the frame, so you buy and cut plywood to lay on it, which also stiffens the shed. Plan a level base underneath as well, since the shed has no floor of its own.
How do I stop it rusting and leaking?
Seal the screws, especially the roof screws, with clear silicone as you build. These kits often ship with too few washers and the thin steel rusts at the fastenings, so siliconing the screws both replaces missing washers and seals against water. Doing it during roof assembly, while it is reachable, is easiest.
Are they any good?
For the price, owners are generally happy once the shed is built, many say it looks like a much pricier model. The caveats are that the metal is thin, there are a lot of small screws, the instructions are picture-only, and it needs a level base, a plywood floor and anchoring. Built with care, it is genuine value.
