Customization refers to the process of adapting a product or service to meet the specific needs or requirements of an individual customer. In the context of PVC pipe conduit manufacturing, customization would involve working with a customer to design and create PVC pipe conduit that is tailored to their specific needs. This may include adjustments to the size, shape, or color of the pipes, as well as the inclusion of special features such as built-in insulation or UV protection.
