Bus Roof Raise Hat Channel

So based on other builds and those numbers i had already decided on 14 gauge hat channel and 18 gauge skin some people go 20 without issues.
Bus roof raise hat channel. I had to make the remaining 14 cuts the day of the raise. Gypsum panels are then screw attached to the furring channels. In concrete wall applications furring channel is installed vertically to the wall surface using concrete nails or power driven fasteners. Hat channels are an alternative type of steel roof framing system which can also be used as a purlin where a lower profile is required or where the cover system requires closer purlin spacing thus making standard z or c purlins overly expensive.
Ahead of the sunday we raised the roof i cut through the rear of the bus the front of the bus and half of the channels. On a 13 row bus we used 4 tubes on each side. Finally each piece of square tubing should be secured into the hat channel by one bolt before the roof raise begins. Why raise the roof.
For the lift we used yardarm boat jacks and 4x4 posts. A raised roof coach is easier to sell and usually is about 15 000 20 000 more value. For me the two and very important decisions were the height of the roof raise and the fasteners. Expand holes with a drill.
The most popular reason is value. We had all of the old hat channel cut ready to raise but there was something wrong with the rear cap. Turns out there was a horizontal support that we had forgotten to cut and the roof would not raise with it still whole. The high hat furring channel is a hat shaped corrosion resistant framing component used to fur out masonry walls and ceiling assemblies.
Whenever you buy a commercial passenger coach there are modifications you will need to make it a comfortable private coach. One of the most popular structural changes to make is raising the roof. To get the 42 square tube down into the hat channel you will have to bang it in with a hammer so make sure you have no screws or rivets on the bottom half of the hat channel. Don t forget the pre drilled holes in the bus hat channel must be expanded to fit your sturdy bolts.
The stock hat channel ribs is 13 14 gauge and the stock skin is 16 gauge. We were hoping to get some new hat channel fastened on to a newly raised bus but hit a snag. Sunday night was kind of tough.
