Underground warning tape plays a crucial role in identifying and protecting buried utility lines, ensuring safety during excavation activities. This tape is typically constructed from durable materials such as low-density polyethylene (LDPE) and features various specifications to meet industry standards. Key characteristics include a minimum thickness of 200 µm, widths ranging from 50 mm to 150 mm, and lengths of up to 500 m or more. The tape is often designed with indelible, lead-free ink that withstands environmental factors, including acids and alkalis, ensuring long-lasting visibility and effectiveness. Additionally, some types incorporate detectable features, such as aluminum backing or stainless steel tracer wires, which aid in locating utilities using specialized equipment. These specifications ensure that the tape not only serves as a visual warning but also facilitates the safe detection of underground installations, thereby preventing accidental damage during construction or maintenance work.
