Bolt Length For Unistrut



Each section of Unistrut channel has four dimension attributes: length, width, height, and wall thickness. Out of these variables, length is probably the easiest place to start. The vast majority of Unistrut channel sections come in 10’ and 20’ lengths. 66 Southern Blvd. Nesconset, NY 11767 USA Tel: 631-467-3939 Fax: 631-979-0605 [email protected] The standard lengths for nearly all Unistrut channels are 10 feet, or 20 feet (though a few are available in 16 foot lengths). So, bear in mind that channel will need to be transported on a box truck or flat bed, unless you have small quantities cut to length for UPS shipping. Channel To Beam U-Bolt Clamp, 3' Length On Plate, 2-1/2' Width On Plate, 3-3/4' Length Of U-Bolt- Pack Of 5 - Product details Product Dimensions: 0.2 x 0.1 x 0.1 inches; 13.3 ounces. The strut comes in pre-cut and deburred lengths of 12″, 24″, 48″ and 120″, with either pre-punched slots and holes or blank/solid for applications requiring specific hole locations. A series of stainless steel, short-thread u-bolts firmly attaches pipe and conduit to the strut in a sanitary manner.

Strut channel, often referred to colloquially by one of several manufacturer trade names, is a standardized formed structural system used in the construction and electrical industries for light structural support, often for supporting wiring, plumbing, or mechanical components such as air conditioning or ventilation systems.

A strut 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 fiberglass, a highly corrosion-resistant material that's known for its lightweight strength and rigidity.[1] Struts usually have holes of some sort in the base, to facilitate interconnection or fastening strut to underlying building structures.

The main advantage of strut channels in construction is that there are many options available for rapidly and easily connecting lengths together and other items to the strut channel, using various specialized strut-specific fasteners and bolts. They can be assembled very rapidly with minimal tools and only moderately trained labor, which reduces costs significantly in many applications. A strut channel installation also can often be modified or added-to relatively easily if needed. The only alternative to strut channels for most applications is custom fabrication using steel bar stock and other commodity components, requiring welding or extensive drilling and bolting, which has none of the above advantages.

In US units, the basic typical strut channel forms a box 1 5/8 inch by 1 5/8 inch. In metric units, this is a 41 mm by 41 mm unit. There are several additional sizes and combined shapes manufactured.

Shapes[edit]

Basic strut channel comes in the open box section, 1 5/8 by 1 5/8 inch square cross section. A half height (1 5/8 inch wide, 13/16 inch tall) cross section version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace. A deep channel 2 7/16 inches tall and 1 5/8 inch wide is also manufactured.

The material used to form the channel is typically 12 gauge (0.1046 inch) or 14 gauge (0.0747 inch) thick sheet metal.

Several variations are available with different hole patterns for mounting to walls and supports. Solid channel has no holes predrilled, and must either be drilled on site or mounted in another fashion. Punched channel has round holes, large enough for 5/8 inch threaded steel rod or bolts, punched in the top of the channel at regular 1 7/8 inch centers. Half-slot channel has short, rounded end rectangular slots punched out on 2 inch centers. Slot channel has longer slots on 4 inch centers.

In addition, shapes are manufactured with two lengths of channel welded together back to back, or three or four welded together in various patterns, to form stronger structural elements.

Materials[edit]

Strut is normally made of sheet steel, with a zinc coating (galvanized), paint, epoxy, powder coat, or other finish.

Strut channel is also manufactured from stainless steel for use where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), from aluminium alloy when weight is an issue or from fiberglass for very corrosive environments.[2]

Standards[edit]

The 'Metal Framing Manufacturers Association' (MFMA) defines a standard for strut channel construction that allows multiple manufacturers' channels to be compatible. The current version of the standard, as of 2020[3], is MFMA-4. Well-known manufacturers of strut channel, including Unistrut U.S., Cooper Industries/Eaton Corporation, and Thomas & Betts Corp./ABB Group, are members of[4] the MFMA and defined the standard.

Interconnection[edit]

The inwards-facing lips on the open side of strut channel are routinely used to mount special nuts, braces, connecting angles, and other types of interconnection mechanism or device to join lengths of strut channel together or connect pipes, wire, other structures, threaded rod, bolts, or walls into the strut channel structural system.

Unistrut Spring Nuts And Bolts

Usage[edit]

  • An overhead electrical wire hanger manufactured from two lengths of strut channel and two lengths of threaded rod.

  • A length of standard half-slotted strut channel used as a brace, connected to a length of half-channel mounted directly to a wall, joined with a purpose-built channel connecting steel angle.

  • A shelf supporting electrical conduit and pipe, manufactured from strut channel

Strut channel is used to mount, brace, support, and connect lightweight structural loads in building construction. These include pipes, electrical and data wire, mechanical systems such as ventilation, air conditioning, and other mechanical systems. Objects can be attached to the strut channel with a bolt, threaded into a channel nut, that may have a spring to ease installation. Circular objects such as pipes or cables may be attached with straps that have a shaped end to be retained by the channel. Strut channel is also used for other applications that require a strong framework, such as workbenches, shelving systems, equipment racks, etc. Specially made sockets are available to tighten nuts, bolts, etc. inside the channel, as normal sockets are unable to fit through the opening.

Unistrut Bolts And Hardware

United Interlock Grating is engineered with a strength-to-weight ratio that allows it to withstand substantial loads while being easy to handle. The male-female legs of the roll-formed grating interlock securely, and double-male legs provide a safe finished edge for end planks.
Two standard surfaces are available: slottedsmooth and anti-skid. Anti-skid is the ideal choice when safe walking conditions are important. Dieformed teeth in the transverse ribs give you 360° of shoe-gripping traction even when the grating is wet, oily, muddy, or icy.
Punched Interlock Grating has an open area of 42% for 9' grating and 35% for 6' grating. This prevents dirt, debris, ice, and snow from building up on the surface and allows light and air to pass through. United Interlock steel grating is made from pre-galvanized steel which conforms to a G-90 thickness designation per ASTM A653. The aluminum grating is made from type 5052 aluminum with a thickness of 0.080'.
Unpunched smooth surface grating is also available for special applications.
