Every body always wants roll up sheet doors. They serve a purpose and fill a whole and there inexpensive. I always try to talk people out of them . This is why :




This was all caused by just wind . And not even what we consider heavy wind . This is not covered under any type of warranty. And thieves can bust thru them just as easy . Customer always think I�m trying to upsale another product and I�m not. Most of these will have to be completely replaced .

Looks like #11 got lucky

Different doors? Or just a good number?

Well, sheet.

It was probably in the up position when the wind came thru

Nicky, just look at it as job security.

We used to call them rolling steel doors. Easy to install.
About 1 out of 10 smallish commercial door installs.

The pictures don�t lie-
But��-
I have had those type doors for over thirty years at places I have managed-
This has never ever happened to one of my doors-

The bigger they are the worse they are. I have an 8x8 on my well house that has not been bad at all. The large ones have more surface area and more flex making them more prone to damage. On my shop the 14x14�s are panel type insulated with struts, I wouldn�t chance a roll up that size. The door guy that installed them said he would never even sell a roll up door.

We had a twenty foot high shop with two big drive thru bays and roll up doors. It faced south and north (drive thru), in SW Houston, behind the Westpark Common Market, under the 500� tower. Daily storms in the summer, Alicia passed directly over it. We made sure to open all four doors when it stormed. The wind blew right thru and swept up for us.

We never lost a door. Just got lucky I guess.

those are not rolling steels there sheet doors . Made of one solid sheet of metal. Rolling steels have individual slats with endlocks /and or wind locks that�s keep them from doing what these doors did .

smart man

Nicky, if these doors are a bad idea, why do people buy them?

Cheaper then the other options.

Nick, did those doors have windlocks properly installed?
I�ve seen 20�x20� coiling steel doors on a paint booth that were bowed in about 2� on each end from negative pressure exhaust fans and clogged up intake filters and those doors stayed in their tracks. They were 18 gauge though to meet fire code so apples and oranges to your OP pics.
Mainly wondering if they had correct windlock installed?
