Playground equipment at schools is very important as children need both unstructured and structured play. But whenever you are looking for equipment for a school it needs more than that which the average parent could buy for their own kids. The cause of that is that the equipments must survive through dozens of kids playing on it daily together with the external weather conditions all while adhering to a strict safety laws. The playground equipment that parents buy is much weaker than what it at parks or schools because it only needs to be designed to be affordable and continue through a few kids sometimes only 1 child. Even though the playground equipment for schools or other organizations cannot be purchased by average parents since it's designed and sold only to organizations. The cause of this is the cost of the equipment, together with other reasons such as: putting the playground equipment together, how deep in the ground the park equipment needs to be, along with the sheer size of the equipment. This is something which no one would ordinarily desire if it had been just their own children. For safe park equipment in schools it must be ordered, and put together by an organization which designs heavy duty park equipment intended for long term usage with a great deal of wear. In order for it to be considered secure it has to be put deep into the ground to make sure as lots of kids play with the equipment it will not tip over or fall upon the kids which are playing on it. For these reasons park equipment in schools while significant for the kids has an ever greater importance to safety for all those children, and that's why most of these high standards are put into place because it is intended to keep each and every child on the playground safe.
