The first thing you need is a box, specifically a fan support box. They make
a shallow box for your situation called a fan support pancake box. It's
about 1/2 inch deep and should be notched into the beam flush with the
surface of the beam. Your steel cable will connect to the box and thus
ground it. The green wires from the fan will also attach to the box via a
grounding screw. You'll need to use a tester to determine which of the two
wires are hot and neutral and connect them to the fan accordingly
