HDPE Black Welding Rod in Spool – Round and Triangle Profiles
This HDPE welding rod is designed for strong, reliable plastic joins in fabrication and repair work. Available in a round 4mm profile or a triangle 5.2mm profile, it suits a wide range of extrusion welding applications, including joining HDPE sheet, pipe, and custom-fabricated components.
The round profile is well suited to general-purpose welding and is available in 170m or 830m spools to match job size, from small repairs to high-volume production. The triangle profile promotes deeper bond strength and a cleaner finish, particularly for large flat sheet joins and corner seams, and is supplied on a 150m spool.
Variation Matrix:
| Shape | Size | Spool Length |
|---|---|---|
| Round | 4mm | 170m or 830m |
| Triangle | 5.2mm | 150m |
Manufactured from UV-stabilised HDPE to tight diameter tolerances, this rod ensures consistent flow, reliable feeding, and high-strength welds — even in harsh industrial environments.
