Hesheng also offers a wide range of components and fittings of cable trays. H-WB Wall Steel ALuminum Bracket is attached to a wall and used to support or hold up cable supporting system. Best choice of Strut support system project regarding Unistrut channel and threaded rod and strut channel fittings and bolt & nut & washer.Unistrut channels divide into Solid or plain channel, Punched channel, slotted channel, half-slotted channel, half channel.Unistrut Channel is a standardized formed structural system used in the construction and electrical industries for light structural support, often for supporting wiring, cable tray system, cable trunking system, cabling system, conduit system, pipe system, steel structure, plumbing, or mechanical components such as air conditioning or ventilation systems. A unistrut is usually formed from a metal sheet, folded over into an open channel shape with inwards-curving lips to provide additional stiffness and as a location to mount interconnecting components. Increasingly, struts are being constructed from materials that are highly corrosion-resistant and are lightweight, has strength and are rigid. Struts usually have holes of some sort in the base, to facilitate interconnection or fastening strut to underlying building structures. Several pre-drilled holes in the channel allow for a flexible choice of where to fasten it, and its interconnectivity accommodates a vast length of channel and perpendicular junctions. H .S. Strut Channel is the original metal framing system featuring a unique weldless connection. The H .S. Steel or Aluminum Strut Channel system eliminates welding and drilling, and is easily adjustable and reusable for infinite configurations.
