Are the ribs made of metal (aluminum) or some other material like plastic/fiberglass?

yes - - a lightweight metal. i just read the answers below. i had bigger, heavier umbrellas in another location and the wind literally bent and buckled them. these are neither lightweight nor flimsy but i wouldn't mess with big winds either...

Aluminum tubing.. have been through several severe thunderstorms here in Atlanta and my umbrella is doing fine but.. when we see severe T-storm or high wind weather reports we do roll it down. It just makes sense as even high dollar commercial umbrellas can only take so much.. :)

Unfortunately PLASTIC. The 2 piece pole, assembles and is pretty thick plastic. The tines I think are also a plastic/composite of some time. Not wooden-like as you would find in a "Market Umbrella".

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 would guess stainless. Definitely not plastic, and too heavy for aluminum.

Metal....aircraft grade aluminum. I think it is better than the plastic one.

No, it is aluminum. When I bought mine it said in the description that it was carbon fiber but it definitely is not.

It's probably aluminum but it is definitely not plastic. It is some type of metal for sure.

no it is definitely not metal. It is a fine mesh nylon-like material. Main structure is plastic.

The frame is made of aluminum.The entire unit is very light & easy to handle.It is hardly noticeable when connected to my Cannondale mountain bike.

No metal.. More like a hard rubber or plastic. Very common and encouraged in most air bed construction.

Not metal. Wood with metal/aluminum outer layer. Looks like metal, but wood on inside. Still just as durable. you won't find a better mic for the money...

I looked over the web, but could not find the answer. However, I have never seen racks of this quality, so I am assuming that they are some grade of steel since they seem too heavy and stable to be made of aluminum.

Steel/aluminum? It is a strong and durable metal. Birds love it and it holds up strong- the squirrels don't like it!

The side bars are metal, aluminum I think, and the baskets are plastic. The baskets are very sturdy, however. I did a lot of research before buying this and I'm happy I chose this. It's well made and durable and it was easy to put together. And the best part is it doesn't swing around when I open and close the door.

Not a materials expert but the outside ribbing appears to be metal. It holds the same finish as the rest of the hardware and so far has been resistant and easy to clean.

I believe so. Maybe aluminum but most likely steel. I passed at least 100# of meat through it at my restaurant with no problems

You need a special rack for the ribs and we didn't buy it. Sorry we don't know. But otherwise we really like the item.
