Axial reinforcement design enhances the overall stability of the channel steel.
The serrated inner edges of the channel work with channel locks to provide anti-slip, impact resistance, and ease of installation.
Auxiliary scale markings on the channel surface facilitate on-site installation and processing.
Post-forming hot-dip galvanization offers strong corrosion resistance and an attractive appearance.
Quick and easy installation, compatible with various types of MEP systems including water pipes, air ducts, and cable trays.
Flexible assembly with other accessories allows for various support and hanger system configurations and on-site adjustments.
