Once the subfloor was completed, we needed to add the C channel. The C channel is a U ish shaped piece of aluminum that runs along the edge of the subfloor. The shell get attached to the C channel. This process is used because the frame/chassis is made of steel and the shell is made of aluminum. If the two metals are in contact with one another it results in galvanic corrosion.
Mr. C had to cut slits in sections of the C channel that had to curve around the corners. The C channel was fastened through the floor with bolts. Sealant was put in each hole prior to inserting the bolts.
