Starduct cable ladder: made of 1.5 ~ 2.0mm steel sheet. Finishes: ZAM K27 from Nippon Steel, Z18 Galvanized steel sheet, powder coating per request. Production: forming and punching machines to create stiffening ribs and slots on the sides. Sides and rungs are connected weldlessly by clinching machine to keep integrity for finish surface as well as improving corrosion resistance.

Special design: the sides is produced with integrated coupler and gounding slot (with bronze grounding coin), this help to eliminate the use of separate couplers, to save up to 55% cost for connection. Production standard: RCVN 10688:2015/ IEC 61537:2006.
