When metal playground components became the standard for wooden systems, the surface temperature safety issue became meaningless due to the innovation of vinyl coating. Immerse the deck in a large tank of liquid polyvinyl chloride (PVC) plastic. But it wasn't long before people realized that the plasticizers needed to make PVC flexible for playground applications pose health risks.
Now, vinyl coating formulations no longer contain phthalates, and other methods that do not contain PVC are also popular. With a textured polyethylene coating, it is durable, flexible, long-lasting, and has a variety of textures, which can provide excellent comfort or improve friction.
Cargo climbers are a playground with a long history, but the natural rope fiber structure is unstable and susceptible to moisture and mold in the outdoor environment. Therefore, if it is not galvanized or composed of stainless steel (which may cost too much), the chain net or the climber's metal changes are susceptible to corrosion. Instead, metal core ropes are used to create bridges, climbing nets, trapezoidal components and other flexible rope designs in contemporary playground structures.
With the continuous development of science and manufacturing technology, the durability and safety of commercial playground structures will continue to improve, while at the same time providing interesting and imaginative spaces for children to learn and grow.
