I have been ask to bid the door in the attached photo. It is 48" x 108" x 2". The client wants a steel 'skin' and pivot hinges. I was thinking of using a mdf core with the steel skin but that is going to very heavy. Can anyone give me advise on construction methods and supplier for the pivot hinges? I have made many interior doors but never an exterior door.
Its a frame with cross rails were the seams of the steel are fastened. It is essentially a hollow door.
The steel will be very heavy on its own. Adding MDF would be a rather heavy mistake.
Use a rot resistant wood to make a frame.
For ease of installation, you want to use a top pivot as on pp. 24/25 http://extranet.assaabloydss.com/library/catalogs/Rixson/pdf/44041_Rixson_Pivots_a
Reminds me of old factory doors, wooden doors covered with a thin skin of metal. I think I'd make it as Adam described as a typical frame and panel door. I'd probably use ply for the panels and make them flush with the face but still allow for movement.
I'm not sure if they ever glued the panels as well as used nails? All the ones I've been exposed to the metal was not glued….or at least not still glued after 100 years or so? But the panels in the door pictured look flatter than most of the factory doors I've seen so???
Well, steel panels are one thing. I want to see how you end up weatherstripping the darn thing with that centered pivot. By the photo, I can't tell what I am seeing by way of panels and/or frame.
I have had several requests for these over the years, but have always stumbled on the weatherstrip - specifically at the pivot points. Rixson center pivots will do it, just be sure to have the weight rated accurately.
The folks making the requests were hung up on the wow factor, and once I walked them thru the long term potential of Winter overcoming the weatherseals, they went with more conventional hinges and resultant seals.
The factory doors I've seen were t&g fir slapped together and then skinned with steel for fire proofing. Not exactly flat.
Other than the industrial look and "antique patina"(dirt & rust) the doors had no redeeming qualities. They were typically hung on a sliding rail with a counterbalance weight. You needed that so you could push them.
Those were in some old New England mills in Connecticut. Perhaps they are looking for the NYC loft look. More industrial with less rust?
The top and bottom get brush type "seals", with a full circle around the pivot. Not really weather tight, but drafty is in, yeah?
As of 2014 all our Exterior Res. Entrys need need to be tested (for Water and Air Infitration) and be certified.This is to go with the new North American Fenestration Act.We can not get that to make Code here in BC Canada.
Looks like a real finger pincher when the kids are around and the door slams shut. grocery stores used to have doors that pivoted like that, they stopped making them for a reason.
