the design concept for my plasma table water tank is almost finalized...
"The Kid" got the OK from his job to come in and use their laser and press
brake to cut and form everything. We're going with 11 gauge material.

One last question. The top plate on my captive air bladder needs to be
removable for future maintenance. Its a 6' x 10' sheet with a grid of
strips spaced 2' x 6' to fasten to. What fastener should I use? Bolts are
likely to just be rusted solid. How about pop rivets, do they drill out
easily? Will a squirt of silicone in the rivet hole seal them up (only .5
psi)? other suggestions.

Stainless steel fasteners?

"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"

Stainless steel fasteners?

The tank is cold rolled. Does it do any good to have a stainless screw?
Yhese would be a stone bitch to drill out when they twist off.

Sorry, guess i didn't describe what i'm doing well enough. If i use screws
they would have to be self tapping into cold rolled straps.

For the 11 gauge plasma tank that you are building????

Stainless hex bodied rivet nuts installed in the angle iron. Coat the
stainless bolts with teflon sealer and assemble.
Or use a captive stainless stud.

Shows you a few options.

Stainless steel pop rivets will NOT drill out easily.
Most likely they will spin in the hole before you can drill through the head.

If you have access to the back side, a pair of vice grips can solve that.

No access. this plate makes it a captive air tank. Say, do they make a pop
rivet that doesn't leave a hollow behind. No way would i use SS pop rivets.

They make closed end pop rivets. www.mcmaster.com, put 3247 in the search
box, for examples.

Will take you right to them.

Sealing Blind Rivets
Also known as closed-end sealing rivets; these fasteners prevent water and
air from passing through or around them. Because 100% of the mandrel is retained
they have higher shear and tensile strength than standard blind rivets of the
same size and material.
Stainless steel rivets and mandrels have excellent corrosion resistance and
may be mildly magnetic. Rivets are 18-8 stainless steel; mandrels are 400 series
stainless steel. Aluminum rivets and mandrels are corrosion resistant and
nonmagnetic. Rivets are 1100 aluminum; mandrels are 7000 series aluminum.
Aluminum rivets with steel mandrel are nonmagnetic. Rivets are corrosion
resistant and made of 5056 aluminum; mandrels are C1006-C1010 steel.
