Overview

The DuraMax Imperial Metal Garage is the strongest steel outdoor building you can find today. While most metal garages have thin, flimsy walls that dent and ding soon after you assemble them, DuraMax metal garages have thicker steel walls and a special rib design for greater strength and dent resistance. The metal reinforced roof support truss system even handles over 20 lb. per square foot of snow.Made with hot dipped galvanized steel frame parts, the attractive design and color of the Imperial Metal Garage goes well in any landscape.

It arrived last Friday June 21, 2024. We were just finishing up on the 13x30 slab it will be built on. A floor drain was put in the concrete floor so when wet vehicles some into the shed the water from snow or rain will run out. We didn't find the instructions to put this together so we are waiting on that so we can get started on the shed.

Very impressed with the frame, I think it might be stronger than my house’s lol. The instructions could be a little better, other than that I’m happy I went with this company.

20’x12’ Durashed Metal Garage

Overall I’m very happy with the garage and its ease of construction. I built the building by myself on an existing slab. I worked slowly doing one or two operations and then stopped and studied the instructions carefully. There are no written instructions, just drawings. However, I found the drawings to be accurate and by following them the construction was easy.
The pre drilled holes were all where they were supposed to be and the parts went together as shown.
One suggestion :
The screws included are all Philips head sheet metal screws and machine screws. Most are about 1/2” in length. It would have been so much easier to assemble if they used hex head screws so a socket could be used to tighten them…they work, but are somewhat frustrating to drive with a standard Philips bit.
The finished product is very sturdy and looks great. It will be perfect as a storage area for my garden tools and inflatable boat and accessories.

I like the size and the color almost matches my existing structure. The package arrived sooner than expected which is always appreciated. I started building the structure i found that a number of pieces had minor damage. I wasn't too concerned and most of it will be hidden by the shell and others I successfully bent back so it wasn't too noticeable. I started putting panels on and when I got to the bottom of the crate a couple of panels were fairly damaged by a fork lift from the under side, unfortunately the damage is quite noticeable and the most damaged panels are the corner wraps by the roll up door side. I included a couple pictures showing some of the damage on the finish side of the panels. I haven't attempted to get replacement parts yet so for now I am giving a 3 star rating. I will update one way or another after that process

It's been good and sturdy so far. Wish instructions were more detailed though. It's as if instructions are meant to be read by contractors not normal everyday consumers.

Working weekends, as time permitted, it took me 4-5 weeks to assemble this shed working by myself. I needed help installing the horizontal struts front and rear, which my wife could do and when it came to the center support assembly, I needed my son but it only took a few minutes of his time. Otherwise, I put this thing together step-by-step by myself. The packaging was perfect and all of the parts were present and in perfect condition.Overall, I was very impressed and happy with the purchase. I started with a 3-4" concrete pad and after it cured, cut 1-1/2" deep cracks with a Skill saw. I used a sealant under the base parts and also between every panel. This is not necessary but for my particular use, it is. Had I not done that, the assembly time would have been less. I just took my time and made sure that everything was plumb and level. This is very important! Take care that your concrete is level and straight. Then everything lines up and all of the screw holes line up perfectly. I think that you need time and quite a bit of patience, then this shed yields a good result. You need to consider every slight detail that the instructions provide. If for example there are 5 screws needed but they say only install 3 at this time, there is a reason.

Buy in january 2017 but assembling in september 2018. Easy to mount but but need to carefully follow the intruction book. Drawn the dimensions on the concrete base very carefully (will avoid any metal stress during assembling). Electric screw driver needed ( more than 1600 screws) ; 2 men for fitting the roof.structure and roof panel . Screw (rep S2) seems fragile ( many head broken during tightening ). Good shape and looking after final assembly. happy feeling !!!
