When standard rigid strut channel isn’t flexible enough for your installation — literally or figuratively — Flex-Strut delivers the answer. Manufactured by Flexstrut Inc., this system offers a wider range of channel profiles, unique flexible products, and a comprehensive fitting ecosystem that handles applications where conventional strut falls short.
Steinco Industrial Solutions carries the complete Flex-Strut line as part of our strut framing channel systems offering. Here’s everything you need to know about what makes Flex-Strut different and when to use it.
What Is Flex-Strut?
Flex-Strut is a metal strut channel system produced by Flexstrut Inc. Like Unistrut, it consists of slotted metal channel sections and a comprehensive range of compatible fittings, nuts, and hardware. Where Flex-Strut differentiates itself is in:
- A broader range of channel profiles and sizes
- Specialty flexible products (Flex-Wrap and Flex-Angle) for curved and angled applications
- A complete line of seismic bracing components including the Klo-Shure and Gripple HangFast systems
- Lab furniture fabrication components
- Telescoping strut channel systems (FTS-200H3 series)
What Channel Profiles Does Flex-Strut Offer?
Flex-Strut’s channel product line spans a wider range than most competing systems:
- FS-100 through FS-700 series: Solid, slotted, and back-to-back configurations in standard 1-5/8″ and 13/16″ profiles
- Universal slot channel (FS-1000 series): Designed to accept both standard and specialized nuts for maximum versatility
- FS-6500 series: Larger channel for heavy-duty structural applications
- Mini-nut channel (FS-600/FS-700): Compact channel systems for light-duty electrical and data applications

What Makes Flex-Wrap and Flex-Angle Unique?
Flex-Wrap
Flex-Wrap is one of Flex-Strut’s most innovative products. It’s a segmented strut channel that can be bent to follow curved surfaces or irregular pathways — something standard rigid channel simply can’t do. Flex-Wrap can be configured to virtually any radius, making it ideal for:
- Curved cable tray and conduit support
- Support structures that follow the curve of a vessel or tank
- Installations in tunnels, curved walls, or architectural structures
- Custom furniture and display fabrication
Flex-Angle
Flex-Angle is a segmented angle section that can be bent to any angle, allowing angled strut members to be created without cutting or welding. It’s particularly useful for diagonal bracing and non-standard-angle connections.
What Fitting Categories Does Flex-Strut Offer?
The Flex-Strut metal strut system fittings catalog is comprehensive, covering:
- Angle fittings: Strut angle fittings for 90° connections in multiple hole configurations
- Beam clamps: Strut beam clamps for attaching to structural steel beams and channels
- Channel brackets: Strut channel brackets for shelf and wall-mount applications
- Pipe clamps: Strut pipe clamps for pipe and conduit support
- Post bases: Strut post bases for floor-anchored vertical support members
- Braces: Strut braces for diagonal and lateral bracing
- Clevis fittings: Clevis fittings for hanging and pivoting connections
- Wing fittings: Strut wing fittings for T-connections and parallel channel assemblies
Specialty Flex-Strut Products
Klo-Shure Seismic Bracing System
The Klo-Shure system is Flex-Strut’s seismic bracing solution for mechanical, electrical, and plumbing systems. It provides the in-line sway bracing required by ASCE 7 and IBC seismic provisions, with pre-engineered components that speed up installation and simplify code compliance.
Gripple HangFast
Gripple HangFast is a tool-free wire hanger system that installs in seconds. It’s ideal for lighter-duty applications — signage, cable trays, light fixtures — where the speed advantage of a no-tool installation is significant.
Hydra-Zorb Cushion Clamps
Hydra-Zorb is a line of cushioned pipe clamps that isolate vibration and noise from mechanical piping. They’re commonly used in HVAC, chilled water, and refrigerant piping applications where vibration transmission to the building structure is a concern.
Concrete Inserts
Flex-Strut’s concrete insert line allows direct embedding in concrete structures for cast-in-place channel connections — the same concept as Unistrut concrete inserts but within the Flex-Strut system.
Lab Furniture Fabrication
Flex-Strut’s lab furniture fabrication components provide a modular framework for building laboratory workstations, shelving, and equipment supports in research and healthcare environments.
Is Flex-Strut Compatible with Unistrut?
For standard 1-5/8″ channel, Flex-Strut and Unistrut share the same slot geometry, meaning channel nuts and many fittings from one system can be used with channel from the other. This is useful when you need to source from multiple suppliers or when only one brand is stocked locally. However, always verify specific fitting compatibility before mixing systems in critical load-bearing applications.
