That is an access point and a directional antenna in one box. You would hook it up to their main router/switch and it would build a new wireless network pointed at the building. It does support PoE, power over ethernet, so you can put the transformer in a convenient location and run just an ethernet cable to it. PoE does have some distance limitations but it will help tremendously with the installation of this type of device.
Once this is installed you will have WiFi pointed at the building. That might be enough but in my similar attempts it hasn't worked. The problem with just using one of these is that your WiFi client, such as an iPhone or laptop, has to be able to transmit its signal back to this device. Being that the client is not setup for directional use, it won't be very effective. The device you are looking at will have better reception of wireless signals than a standard omni-directional antenna, but I wouldn't count on it being enough.
The next step is to put one of these devices at each end of the wireless link, pointed at each other. This will allow you to setup a very solid wireless connection between the devices and keep them focused on just that link. From the metal building's device you would run another ethernet cable (and PoE brick) down to another wireless router, if they want wireless device support in the building, or just a switch if they just want wired devices.
Another option is to use normal off the shelf access points and buy directional antennas. This is the approach that I've tried with my neighbor and so far I've been completely unsuccessful. I've tried 3 different directional antennas tied to both a WRT54G and my AC1900 and neither were able to setup a solid link to the devices in his house. I had as much luck with cut open coke cans as I did with off the shelf antennas. I have a couple more steps to try before I give up but I'll probably end up with a device just like you found on both sides of the link. If you are curious, my neighbor won't spend the money on internet at his house, that's part of the reason he can afford to own 18 or so cars. I have plenty of bandwidth and I'm over there enough that I want it available when I'm there.
