When constructing a factory building or warehouse, the decision to use PVC roofing tiles should take into account the unit price of the material, installation costs, and the cost of auxiliary materials. The unit price of the material is influenced by thickness and formulation; using thicker sheets or higher-quality raw materials will increase costs but improve weather resistance and wind resistance, offering better value for money in the long run. Focusing solely on the unit price of the material may lead to budget overruns, so it is necessary to comprehensively evaluate the actual total cost.
