Hmm, I wonder what would be cheaper, having the metals company drill the holes or taking the time and drill bits to lay out and drill em yourself?

jmb, if you want to make one a bit taller for architectural millwork and the like, one of the standard sizes of plate steel is 5 x 10 ft, I'd go three or four plates long.  Even be able to do some driveway gates on a rack that's 10'x20',  ;D

You wouldn't want a 10x20' plate steel wall falling on you [eek] [scared]

I'd be very curious about how much the clamping pressure would deform the holes (if at all) in 7~8mm aluminium plate.

Atlas Steel in Oz offer:

Aluminium Plate
Alloy    5005, 5052, 5083, 5186, 5454
Temper   H32, H34, H116, H321
Thickness (mm)   4 to 25
Width (mm)   1200 to 2500
Length (mm)   2400 to 12000, Customer specific length
Finish   Mill, Customer specific finish,
Coating   PE Coating (not standard)
Plasma profile   To customer drawings

... you'd just need a frame and some very accurate hole drilling - imagine drilling a hole in the wrong spot of your 2500x5000 aluminium plate [crying]

Good thing about aluminium I  can do it on my cnc.

I might do it with 30mm birch ply.

Funny you mention driveway gates. I just started doing one last week. 
Cantiliver... welded two existing gates together onto rail.  With angle iron welded on top for when i get round fitting top wheel supports.

Just gotta attach rack and pinion and motor and a post on the closing side.

Excuse the welding i had a few goes. After my dad decided I would be best practesing on scrap lol haahaa
Plus using the old welder and 25year old welding rods was pretty much impossible eventually welded 60% of it decided to buy a new welder and welding rods.  Man the difference!!! So much easier.

Similar clamping systems like that come up various auction sites 2nd hand for a fraction of the cost. Not as sophisticated but maybe a good basis to adapt to work for you.
Nice to have the capability to clamp door frames but not that necassary as everyone seems to use screws to pull the joint up tight whilst the glue goes off.

Before aluminium or brich ply, try Panzerholz. If you have never heard the name, I am going to make it easy for you.
Just give them a call for pricing and info.

Panzeholz is a good shout, as an engineer of steel rather than wood in my day job.

If you can afford the weight, mild steel would be great for cost and strength. But stupidly heavy. 5000 x 2500 would be around 1000kg.

The best way would be to get it laser cut, in smaller sections. Then if wear, corrosion, damage occurs you can replace that section.

2400 x 1200mm sheets are standard, so that would be a good size for the height. Next size up is 3000mm x 1500mm. With the laser we can hold around 0.1 to 0.2mm accuracy on holes at 20mm for round/taper. But you could chase them through with a drill pretty quickly.

You would then just have in each corner some countersunk allen heads to bolt each panel into your frame.

Fascinated by this idea. But the cost and the weight are crazy. I think perhaps just situation specific solutions could be found. Holding band clamps, Pin nailers instead of clamping where the surface is painted or heavily finished. Maybe just welding up a purpose built frame in metal for a serial production run of oversized pieces. Just a set of good normal sided clamps and a hardwood table with lots of dogholes..
