Just a quick question. What material are barn doors made of? Anything else i can make them out of so they dont burn?

They are metal. I never really wondered what kind of metal, but they are definitely metal.

I would say you basically NEED metal, or else something nasty will happen to it, and it probably has to be a certain type, treated a certain way, with heat resistant paint.

If you do use metal for your doors, remeber that it is a great conductor of heat and therefore you need to wait for it to cool down if you want to use it again.

wow ok noobs sorry but im a lighting disigner by profession ok basicly barn doors are made out of two kinds of metals alluminum and steel alluminum are lighter and cool faster they also come in various sizes smallest to largest (4",6",8",10",1') thats basicly yor average sizes...but the also make custom barn doors for say an oddly shaped light (ussually sell from manufacturer) thes lights are like hmi lights and some scoops, pars, fresnels, and cycs(square floods) need a custom barn door.
why wait for it to cool down its not gunna worp or anything and if your worryed bout heat i suggest kevlar gloves.

I may just be a noob since I've only been working with stage lights (and barn doors) for the last 12 years, but, Erol, if I were to build barn doors like you implied, I would use inexpensive sheet metal that you can buy at most hardware stores.

I've never built any myself because I find black wrap that much more versatile for what I do. I did provide a link to someone who did make barn doors for a home depot style work like on my website's lighting primer. I'm sure you could adapt and improve upon this design for whatever you are doing.

thanks joren i did forget about your site. should have taken a look before
