What are the structural limitations of PVC when used in freestanding outdoor sculptures?

PVC (Polyvinyl Chloride) is a popular material for outdoor sculptures due to its affordability and versatility. However, it has several structural limitations when used in freestanding designs. First, PVC lacks the inherent strength of metals or stone, making large or complex sculptures prone to bending or warping over time. Exposure to UV rays and extreme temperatures can cause discoloration, brittleness, and cracking, reducing longevity. Additionally, PVC is lightweight, making it susceptible to wind damage unless properly anchored. Its synthetic nature also raises concerns about environmental impact and long-term sustainability. While PVC is easy to work with, these limitations make it less ideal for permanent, high-stress outdoor installations. Artists must weigh these factors when choosing materials for durable public art.
