Lightweight fire pan?

Use a disposable aluminum turkey roasting pan from the grocery store.

What is the reasoning behind the requirement?

Fire scars, most likely.

The requirement calls for a minimum 12 inch diameter and 2.5 inch "lip around the edge." It looks like a disposable turkey roasting pan will do the trick. Thanks Aaron!

You said boaters are required to carry fire pans? Does that mean no matter what or only if you want to have a fire?

Either way I would test whatever you decide to use, campfire coals are very hot. Wouldn't want to melt a hole through it.

I would think a cheap aluminum roasting pan might not do the trick. The bottom would melt out pretty fast with a fire and probably not last for more than one if at all.
You can totally melt a pop can in a regular fire.

I could be wrong, you could try it at home first to see if it is doable.
You could take a new paint can and burn in it.

Bringing this back from the dead. We've got a kayak trip to Canyonlands this summer and I'm also looking for some relatively lightweight solutions as well.

Requirements:

"A metal fire pan that is at least 12 inches in diameter with a 2½-inch lip around the edge."

Obviously a kayak can carry heavy gear, but I wouldn't mind a lightweight option. We've been thinking of pie tins, motor oil catch pans, steel buckets cut up, gold pans, etc. Any other creative solutions?

Can you find a 12" diameter deep dish pizza pan that has a 2.5" high lipped rim?

There is a cool DIY fire pan designed for kayaker's. It breaks down into a nice compact size and can be assembled pretty fast with just a few wing nuts. It's all aluminum and varies in weight depending on thickness of metal you use.

There is also some commercial offerings like these at austinkayak and I think NRS.

Rectangle is more space efficient.Take a look at these:

I agree with those who were skeptical of an aluminum foil baking/roasting pan holding up to a hot fire. Tried this once and my wood fire went right through the bottom of the pan. If the pan was placed snug (with no air gaps) against or dug into a trench in cold wet sand, you could probably get away with it.

I have made (for personal use for cold weather backpacking in areas without fire rings) a small fire pan out of titanium foil pieces that are hooked together in such a way that it can be folded and rolled up into a very compact size. Weighs about 4 oz as I recall. If someone is interested in copying the design, I can post a picture. If someone wants me to make them one, please contact me through my site rather than by PM.

For canoe or kayak camping, why not take a wok or a regular steel baking pan and use that as a fire pan, where weight is not so much of an issue.

I don't know you can meet the BLM regs and still be lightweight and reasonably priced. I found an option on Amazon which meets regs, will work for the intended purpose and weighs less than a pound (when you subtract the lid weight): http://www.amazon.com/dp/B0006SGQFY/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=35V9MXAN0EIXH&coliid=I1HIBTWSPDJF3F

Can't find one now, but I've seen designs that use a fire blanket set inside a collapsible metal frame. Light and easy to pack. Might be easy to DIY. Fire blanket won't last forever, but easy to replace. River regulations are often blindly enforced. Once I called about needing a fire pan on a river where fires were banned. Still required, told we might need to build an emergency fire. In 90° F+ summer weather. — Rex
