Main Application

C channel steel has a high strength and good toughness, as well as simple processing and installation, which result the profile in becoming the core structural building material that finds broad applications in construction, electrical and machinery industries.

Cable Tray and Electrical Conduit Support: For Use in Commercial and Industrial Applications For Securing Cable Trays, Conduits and Wiring

System Solutions:Application TypesAvailable Types Features Residential/commercial UseYes Alarm SystemConduit TypeRigid Raceway Flexible Conduit Flexible Metal Conduit (FMC) Flexible Plastic Conduit (FPC). The slotted modular design of the system enables fast deployment and change of electrical elements, facilitating installation and maintenance, and ensuring safe, reliable wiring.

Industrial Warehouse Racking Systems: Ideal For Constructing Strong — yet High Adjustable — Modular Racks Needed In Industrial and Warehouse Applications Such As Shelf Racks, Pallet Racks & Bin Racks. High load, flexible layout and dramatically better use of storage space.

Pipe and HVAC Duct Hangar: It is popular used to hang water supply, drainage, fire protection and HVAC pipes and duct at home, factory or commercial. High bearing capacity, wide applicability, anti-vibration and anti-loosening, suitable for various working conditions, guaranteed long service life for pipelines.

Factory Workshop Structural Frame: It is applicable for workshop machinery and workbench, steel structure mezzanine and safety fence. Sturdy and durable to manufacture Automobile industries, good welding performance for manual or robotic welding.

Solar panel mounting racks and supports for industrial applications: Carbon steel can be used to produce solar photovoltaic mounting racks, or other heavy industry applications such as industrial lighting and heavy equipment holding. They are hot-dip galvanized/powder coated for corrosion protection, and can be used in the outdoor or in coastal or humid or harsh environments with a long service life.
