EMBEDDED CHANNEL

Channel Embedded Part

Basic Definition

Cast-in channels are toothed C-shaped steel profiles pre-embedded into structures before concrete pouring. They are welded assemblies consisting of channel bodies and T-shaped anchor rebars. Matched with T-bolts during subsequent installation, they enable flexible mounting of pipelines, supports, curtain walls and electromechanical equipment without drilling or welding, serving as a replacement for post-installed chemical anchors and expansion bolts.

Core Components

Channel Body: Toothed internal C-shaped profile, allowing T-bolts to slide freely along the channel for horizontal and vertical position adjustment.

Anchor Legs: T-shaped / I-shaped anchor rebars embedded in concrete to provide tensile and shear load-bearing capacity.

Supporting Fittings: T-bolts, nuts, plain washers, spring washers and foam sealing strips (used to block channel openings before pouring to prevent concrete slurry intrusion).
