These are made of steel. A quarter is .950 round by .066 thick. The token is .988 round by .060 thick. They work fine in my machines.

They are metal. Be aware, however, they are not easy to install. If you can't solder or weld find someone that will install them for you before purchasing.

They are made of aluminum. The are very strong. I can sit on them without any flex or give.

The ones I got are steel. When I ordered I didn't notice that they were available in aluminum too

They're metal. I would have guessed aluminum, but they're ferrous so probably some alloy.

No they are aluminum. What you are seeing are plastic sleeves that were there I assume for shipping.

According to some reviewers, they are made of COPPER COATED ALUMINUM wire. The specified weight is also the same as other COPPER COATED ALUMINUM cables, 7.4lbs.

They do not say. They are not cast iron. They feel heavier and sturdier than aluminum, but they are coated with "Calphalon" top and bottom so there is no visual of the metal. My guess would be steel, but that's just a guess.

They are aluminum just like the rest of the frame held together with plastic interlocking clasps. I have a single spring mattress on them and so far it has been a comfortable sleep.

I believe they are aluminum. Have only had for about 6 months and they seem to be doing just fine.

I believe they are tin or a similar alloy. Aluminum is not a good electrical conductor. The rails are hollow and can be deformed if you step on the track.

These are stamped steel and are .10" thick. They could be bent with a hammer and a vise

They are solid metal. They have a slight weight that you can feel and it lets you know.

They are made from metal. I was the lucky one to put the item together. The metal is roughly an eighth of an inch thick. Once together the set up is pretty sturdy.

I believe they are aluminum vs. stainless. Not real sturdy, but do the job.

I can safely say they are galvanized "metal". Not sure about steel verses tin or aluminum, but they are definitely metal and I would suggest that they are unlikely to burn under normal circumstances.
