SUPERSTRUT

SUPERSTRUT is a brand of metal framing and support systems used in electrical, mechanical, and industrial construction. The product line centers on strut channels and a range of associated fittings, clamps, and fasteners that together form a modular support framework. Commonly known as strut, the system is used to support conduit, pipe, cable tray, and equipment in commercial, industrial, and infrastructure installations. The brand's origin is tied to the development of the original strut channel in the early 20th century, and it has since become a generic reference for this category of products. 3G Electric supplies SUPERSTRUT components globally, serving plant engineers, maintenance managers, and procurement specialists who require these parts for new builds, expansions, and maintenance activities.

About SUPERSTRUT

SUPERSTRUT is a brand of metal framing and support systems used in electrical, mechanical, and industrial construction. The product line centers on strut channels and a range of associated fittings, clamps, and fasteners that together form a modular support framework. Commonly known as strut, the system is used to support conduit, pipe, cable tray, and equipment in commercial, industrial, and infrastructure installations. The brand's origin is tied to the development of the original strut channel in the early 20th century, and it has since become a generic reference for this category of products. 3G Electric supplies SUPERSTRUT components globally, serving plant engineers, maintenance managers, and procurement specialists who require these parts for new builds, expansions, and maintenance activities.

The SUPERSTRUT product range includes strut channels in various profiles, such as standard 1-5/8 in wide channel, and a comprehensive selection of fittings: conduit and pipe clamps, channel covers, electrical boxes, and fasteners like hinged trapnuts. These components are manufactured from steel and are available with different finishes, including electroplated (often gold-colored) and galvanized (silver-colored), to suit indoor and outdoor environments. The electroplated finish provides a degree of corrosion resistance, while galvanized offers a more robust protective coating for exposed or humid conditions. The products are designed to meet common industry standards for material thickness and load capacity, though specific ratings depend on the exact model and installation.

Application categories for SUPERSTRUT products span electrical raceway support, mechanical piping support, and general equipment mounting. For example, the Angler Conduit Clamps secure rigid metal conduit (RMC) to strut channels, with models available for 1/2 in through 2 in trade sizes. Strut channel electrical boxes, such as the 2-way and 3-way support boxes, provide mounting points for wiring devices within the framing system. Channel covers, like the closure strips for 1-5/8 in channel, protect the open face of the strut from debris and offer a finished appearance. Hinged trapnuts, with thread sizes from 1/4"-20 to 1/2"-13, enable fastening of threaded rod or bolts to the channel without the need for additional hardware.

Technical buyers will find that SUPERSTRUT components are characterized by their material specifications and finishes. The steel construction typically conforms to standard gauges, such as 14 ga for certain clamps, and the finishes are applied to enhance durability. The modular nature of the system allows for field adaptation and reuse, which is valuable in maintenance and retrofit projects. 3G Electric supports the SUPERSTRUT line by maintaining inventory of these components and providing global shipping. The company's role is to interpret demand and deliver the specified parts, ensuring that customers receive the correct items for their applications. With a focus on industrial and electrical supply, 3G Electric serves as a source for SUPERSTRUT products, complementing other lines of burners, pumps, and gas controls.

Common Applications

  • Electrical conduit support in industrial plants — SUPERSTRUT Angler Conduit Clamps secure 1/2 in to 2 in RMC to strut channels.
  • Modular framing for equipment mounting — SUPERSTRUT 1-5/8 in strut channel with hinged trapnuts for adjustable support structures.
  • Wiring device installation in commercial buildings — SUPERSTRUT 2-way and 3-way electrical boxes mount devices within strut framing.
  • Corrosion-resistant support in humid environments — SUPERSTRUT galvanized channel covers protect strut openings from debris and moisture.
  • Fastening threaded rod in mechanical rooms — SUPERSTRUT hinged trapnuts with 1/4"-20 or 1/2"-13 threads secure rods to strut channels.
  • Cleanroom or finished ceiling installations — SUPERSTRUT electroplated gold channel covers provide a finished look and prevent dust ingress.

Frequently asked questions

Common questions about SUPERSTRUT from 3G Electric.

What is the difference between the electroplated and galvanized finishes on SUPERSTRUT strut channels and fittings?

SUPERSTRUT offers both electroplated and galvanized finishes. Electroplated finishes, often gold in color, provide a thin, decorative, and mildly corrosion-resistant coating suitable for indoor or dry environments. Galvanized finishes, typically silver, offer a thicker zinc coating that provides better corrosion protection, making them suitable for outdoor, humid, or industrial settings where exposure to moisture or chemicals is a concern. The choice depends on the specific environmental conditions and required service life. Both finishes are applied to steel substrates, and the underlying material properties remain consistent.

What sizes of rigid metal conduit (RMC) can SUPERSTRUT Angler Conduit Clamps secure?

SUPERSTRUT Angler Conduit Clamps are available for a range of RMC trade sizes. For example, the C109-1/2 model secures 1/2 in RMC, while the C109 2 model accommodates 2 in RMC. These clamps are designed to mount conduit to strut channels, providing a secure support point. The clamps are made of steel with an electroplated finish. When selecting a clamp, ensure the trade size matches the conduit outer diameter. Installation typically involves attaching the clamp to the strut channel using standard strut nuts and bolts.

What are SUPERSTRUT hinged trapnuts and how are they used?

SUPERSTRUT hinged trapnuts are fasteners designed for use with strut channels. They feature a hinged design that allows them to be inserted into the channel at any point along its length, eliminating the need to slide them from the end. Once positioned, they provide a threaded connection for attaching bolts or threaded rod. Models are available with thread sizes such as 1/4"-20 and 1/2"-13. They are made of steel with a galvanized finish. Typical applications include securing conduit clamps, pipe supports, or equipment to the strut framework. The hinged feature simplifies installation and adjustment in the field.

Can SUPERSTRUT strut channel electrical boxes be used in outdoor installations?

SUPERSTRUT strut channel electrical boxes, such as the 2-way and 3-way support boxes, are made of steel with an electroplated finish. While the electroplated finish offers some corrosion resistance, it is generally intended for indoor use. For outdoor or wet locations, additional protection or a different finish may be required. The boxes are designed to mount electrical devices to strut channel framing. It is important to consider the environmental conditions and applicable electrical codes when specifying these boxes for outdoor applications. Consult local regulations for suitability.

What is the purpose of SUPERSTRUT channel covers?

SUPERSTRUT channel covers, also known as closure strips, are designed to cover the open face of 1-5/8 in strut channel. They serve two main purposes: preventing debris, dust, or moisture from entering the channel, and providing a finished appearance. The covers are made of steel and are available in electroplated (gold) or galvanized (silver) finishes. They snap into the channel opening. By keeping the channel clean, they help maintain the integrity of the support system and reduce maintenance needs. They are commonly used in visible installations where aesthetics matter or in dirty environments.
