Blue Underground Warning Mesh

Blue Underground Warning Mesh

Blue Underground Warning Mesh is a blue plastic mesh roll for marking buried utilities during underground construction and excavation work. It is also known as non-detectable underground warning mesh, blue utility warning mesh or underground warning netting. The mesh provides a visible layer between the buried service and later excavation activity.

Made from 100% HDPE, the 60gsm mesh is light enough to handle on site and easy to place in a long continuous roll. Its blue colour makes the warning layer easy to distinguish from surrounding soil when the ground is opened. This is a standard visual-warning product, not an electronic locating system, so it does not replace the customer's required plans, markers or site procedures.

The listed roll is 30cm wide and 100m long, with 120 x 26mm elongated oval openings and a 60gsm weight. This format suits project buyers who need a wider underground marker than a narrow warning tape, while still keeping transport and installation simple. The product is supplied as a blue standard version; colours, printing and other project details should be confirmed before production.

Typical uses include marking buried water lines, stormwater services, cable routes, ducts, pipes and other underground utilities where a visual warning layer is required. The exact colour meaning and any printed wording should follow the project specification and local utility-marking practice. Installation depth and placement should be decided by the responsible contractor.

YONGTE manufactures HDPE mesh in Shaoxing, Zhejiang. Its 4,600 m² factory operates 8 extrusion production lines and 12 sets of production machines, and the company exports to more than 50 countries. The location in the Zhejiang manufacturing cluster supports production coordination, while Ningbo and Shanghai ports support export arrangements. CE, REACH and SMETA (Sedex) provide documented company-level compliance support.

FAQ

Q1: What is the difference between this mesh and a detectable warning mesh?

This is the standard non-detectable version. It is used as a visual warning layer and is not designed for electronic locating. Buyers requiring a locating function should confirm a separate detectable construction before ordering.

Q2: Is the 30cm x 100m roll suitable for utility projects?

The 300mm width and 100m roll length are intended for project use above buried pipes, ducts, cables and other underground services. Final placement and installation should follow the contractor's site plan and local requirements.

Q3: Can the blue mesh include printed wording or be made in another colour?

Colour, printing and project-specific details can be reviewed before production. Blue is the specification for this listing; please confirm the required wording, colour code and order quantity before requesting a customised version.
