In above ground models, wood is much better than steel. If you "rough house" in a steel pool, you potentially could knock it down. It you run into it with a bike or lawn tractor you will likely know it down. A wood pool you could back your car into and not know it down. Wood you probably need to treat every 3 years, steel you don't, but it will rust. I don't have info on concrete.
Concrete has a lot of creases and bumps and the wooden ramp is smooth
Wooden and concrete
Concrete patios a typically cheaper then wooden decks. Concrete patios are made to resist winter weather. Wooden decks require treating, and cleaning. If the question if over price, then I would go with the patios, cheaper in the long run.
A Wooden float is the flat surfaced tool that is used for smoothing the surface of concrete prior to it setting. A wooden float produces a reasonably non slip surface as it pulls up sand out of the concrete mix to the surface.

Most manufactures do not recommend installing solid wood onto concrete.
There are several advantages to building decks and patios out of concrete as opposed to wood. Building a wooden structure would require assistance from someone with a knowledge of working with wood. taking into account the durability and aesthetic quality required. Wooden structures are usually more expensive to build than concrete and assembly would require great patience and skill. A concrete patio, however, is on the whole an easier project to undertake and whether using simple pouring concrete or ready-made slabs, the task is less daunting as the process is simple - excavation of the area in which you wish to build the patio, leveling of the area with building sand or similar, and then lay the concrete or slabs.
Mostly wooden with concrete/masonry basements.
Wooden blocks will (usually) float. Concrete blocks sink.
because they put all kinds of concrete and bricks as long as a wooden frame.

Most single family homes are still built with wooden frames, but many also use concrete block and brick. Multifamily homes, such as apartments may have wooden frames, but many will use brick, block or concrete, as well as steel framework.
