For all the years I have been building sheds, I have found the following shed door hardware to be the best you can use for building shed doors. Not only for ease of installation, but also for security purposes.
One of the easiest and most versatile shed door handles to use is the 'T' style handle. This is in reference to the shape of the front part of the handle itself. It's installation is very simple. It comes with 2 pieces. The front piece which is the 'T' handle which includes the locking mechanism and a shaft, and the back piece which is another handle that slips over the shaft.
Basically all you have to do after determining the proper location on your shed door is to drill one hole, insert the front 'T' handle, then place the back handle over the shaft and tighten down the set screw and that's it. For security, it also locks!
One of the chicken coops I built years ago had a door handle on it like the one shown below.
If you're going to use this one, you may have to end up adjusting your door slightly over the years because the receiving unit has to be lined up perfectly with the latching mechanism. If the alignment gets off somewhat, your mechanism won't latch properly.
The hinges shown above are great as they are heavy duty hinges and are perfect for using on your shed doors.
The shed door hinges above are t-strap hinges and work great on lighter shed doors.
Another option for keeping your shed doors locked is with this lockable hasp shown above. Effective method of locking your shed doors but I would add an extra door handle for ease of opening.
Barrel bolts are installed on the interior surface of your shed door to keep it closed. Unlatching will allow you to open it obviously, but the reason I like them is that when you have both of your double shed doors closed, there won't be any play in the doors if for example they were closed and you pull on the handle, there won't be any movement outward of your doors.
This is an effective method from stopping a theif from getting into your shed.
One of the best things you can do for your new shed is to protect your shed floor where your shed doors are located. Rarely do I see homeowners doing this after building a shed. The cost is so minimal and the benefit so great.
This area of your floor will deteriorate quickly without any sort of protection because of the beating it may take with moving mowers, etc, in and out frequently. You can find these metal threshold pieces at your local hardware stores.
All you have to do is go to your favorite big box store like Lowes or Home Depot and buy a length of aluminum angle iron, preferably about 2" on each side, cut it to length, and screw it down to your floor. Don't go with the really thick stuff, you just need about 1/8" thick aluminum.
