SUPERSTRUT

SUPERSTRUT is a brand of metal framing and strut channel systems, widely used in industrial, commercial, and infrastructure applications for supporting piping, conduit, cable trays, and mechanical equipment. The brand is part of the Atkore International group, a global manufacturer of electrical and mechanical products. SUPERSTRUT products are engineered for structural support in environments where load-bearing capacity, corrosion resistance, and ease of installation are critical. The product line includes slotted and solid strut channels in various gauges (12 ga, 14 ga) and materials (steel, pre-galvanized steel, 304 stainless steel), as well as a comprehensive range of fittings and accessories such as beam clamps, wire rod clamps, and purlin clamps. These components are designed to meet ASTM B633 standards for zinc plating, ensuring consistent corrosion protection in indoor and sheltered outdoor applications. The slotted channels feature 9/16 in x 1-1/8 in holes (or 7/16 in x 3 in long slots for stainless steel variants) to accommodate standard hardware and provide adjustability during installation. Beam clamps from SUPERSTRUT are available in iron construction with zinc-plated finishes, offering load capacities from 250 lb to 750 lb, and thread sizes from 1/4"-20 to 3/8"-16, suitable for attachment to girder flanges up to 1 in thick. These clamps are used for suspending threaded rod, wire, or purlin systems. 3G Electric supplies SUPERSTRUT products globally, maintaining inventory of common SKUs such as the A1200HS 20 (12 ga steel slotted channel, 20 ft length) and the 500-SC beam clamp. The brand's focus on standardized dimensions and compatibility with industry-standard strut fittings makes it a practical choice for engineers and contractors who require repeatable, code-compliant support structures. SUPERSTRUT channels are typically supplied in 20 ft lengths, with options for pre-galvanized or zinc-plated finishes to match environmental exposure requirements. The stainless steel variants (304 grade, polished finish) are suited for corrosive or washdown environments. All products are designed for use with standard nuts, bolts, and spring nuts, simplifying procurement and installation. 3G Electric supports the line with logistics for global shipping, ensuring that project-specific quantities can be sourced without minimum-order constraints typical of specialty distributors.

Frequently asked questions

Common questions about SUPERSTRUT from 3G Electric.

What materials and finishes are available for SUPERSTRUT slotted strut channels?

SUPERSTRUT slotted strut channels are available in steel (zinc-plated or pre-galvanized) and 304 stainless steel (polished finish). Steel channels are typically 12 ga or 14 ga gauge, with a silver color. Pre-galvanized channels offer corrosion resistance for indoor use, while zinc-plated channels meet ASTM B633 standards. Stainless steel variants are suitable for corrosive environments and feature long-slotted holes (7/16 in x 3 in) for adjustability.

What load capacities do SUPERSTRUT beam clamps support?

SUPERSTRUT beam clamps, such as the 500-SC (MPN 500-SC), 501, and 502 models, have load capacities ranging from 250 lb to 750 lb. These clamps are made of iron with a zinc-plated finish and are designed for use with girder flanges up to 1 in thick. Thread sizes vary from 1/4"-20 to 3/8"-16, allowing compatibility with standard threaded rods and hardware.

Are SUPERSTRUT channels compatible with other brands of strut fittings?

Yes, SUPERSTRUT slotted channels are designed to industry-standard dimensions, including 9/16 in x 1-1/8 in slot holes (or 7/16 in x 3 in for long-slotted stainless steel). This compatibility allows them to work with standard spring nuts, bolts, and fittings from other major strut manufacturers, simplifying integration into existing support systems.

What standards do SUPERSTRUT products comply with?

SUPERSTRUT beam clamps and channels are manufactured to meet ASTM B633 for zinc plating, which specifies coating thickness and corrosion resistance. The channels are also designed to comply with typical structural support codes for electrical and mechanical installations. Specific product certifications may vary by SKU; consult the manufacturer's documentation for detailed compliance information.

Can SUPERSTRUT stainless steel channels be used in outdoor or washdown environments?

Yes, SUPERSTRUT 304 stainless steel channels (e.g., MPN A1200S 10SS) are suitable for outdoor, marine, or washdown environments due to their corrosion resistance. The polished finish provides additional protection against pitting. These channels are typically used in food processing, pharmaceutical, or chemical plants where hygiene and durability are required.

What lengths are SUPERSTRUT slotted channels available in?

SUPERSTRUT slotted channels are commonly supplied in 20 ft lengths, as seen in SKUs like A1200HS 20 and B1400HS 20. Custom lengths may be available through special order. The 20 ft standard length is typical for industrial framing applications, allowing for efficient cutting and installation on site.
