Unistrut Clamp Specification
Material :
- Unistrut pipe clamps, unless noted, are punch-press made from hot-rolled, pickled and oiled steel plates, strip, bar or coil, and conform to one or more of the following specifications: ASTM A1008, A575, A576, A635, A1011 SS GR 33, A1011 HSLAS GR 45, A1046 or A36. The fitting steel also meets the or exceeds the physical properties of ASTM A1011 GR 33. The pickling of the steel produces a smooth surface free from scale. Many items are also available in stainless steel, aluminum and fiberglass. Consult factory for ordering information.
Finishes :
Pipe supports are available in:
- Electro-galvanized (EG), conforming to ASTM B633 Type III SC1
- Hot-dipped galvanized (HG), conforming to ASTM A123 or A153 (hardware)
- Green Powder Coat (GR), conforming to commercial standards for Powder Coating, and plain (PL)
- Unistrut Defender (DF), conforming to ASTM A1059 or A1046
*** Perma Green finish is a commercial grade finish, and as such scuffs and scratch marks are to be expected. If a flawless finish is desired, it is recommended to apply a matching touch up paint ***
Application :
- Unistrut pipe clamps, pipe hangers, brackets and rollers are designed for the support of electrical and mechanical services. Supports to meet nearly every requirement can be attained using Unistrut Metal Framing components.
Dimensions :
- Imperial dimensions are illustrated in inches. Metric dimensions are shown in parenthesis or as noted. Unless noted, all metric dimensions are in millimeters and rounded to one decimal place.

Features & Applications of Unistrut Channel Clamp:
- Durability: Constructed from premium-grade steel and tested to meet industry standards.
- Corrosion Resistance: Hot-dipped galvanized finish ensures longevity in both indoor and outdoor environments.
- Ease of Installation: Designed for quick and hassle-free mounting.
Features of Unistrut Channel Clamps
The following are different features of Unistrut Channel Clamps making it an ideal choice for most uses.
- Heavy-Duty Construction: The clamps are actually made up from thick steel to prevent bending under heavy loads.
- Corrosion Resistance: A thick protective coating stops rust in wet or outdoor environments.
- Universal Compatibility: The design fits all standard channel sizes and matching hardware pieces.
- Tool-Only Installation: Parts assemble easily using standard hand tools without needing special permits.
- Pre-Drilled Holes: Ready-made openings save layout and alignment time during multi-pipe setups.
- Customisable Surface: The exterior easily accepts paint for color-coding or visual matching.
Benefits of Using Unistrut Clamp Brackets
Explore the key advantages of using Unistrut clamp brackets to optimize your industrial framing installations:
- Faster installation: Two-bolt assembly replaces field welding, cutting connection time from 15–20 minutes per joint to under 3 minutes. On large runs with 50+ connection points, that's a full day of saved labour.
- Risk-Free Structural Assembly: Eliminates hot-work fire hazards and weld-defect risks from the job site, giving predictable structural performance with conventional hardware.
- Flexible positioning: Clamps slide along the channel slot before tightening, allowing precise adjustments without disassembly. Repositioning after installation takes under 2 minutes per clamp.
- Easy maintenance: HDG coating needs no periodic treatment. When a cable run changes, clamps release and reposition without cutting or grinding existing channel.
- High durability: 5mm steel with hot-dip galvanizing handles 20+ year service life in exposed industrial and coastal environments.
FAQs
What is a Unistrut clamp?
Unistrut clamp is a heavy-duty steel bracket which connects structural channel sections together or holds them to surfaces via mechanical bolt-and-nut assembly without welding.
What is the purpose of a Unistrut channel clamp?
It anchors unistrut channel assemblies at connection points, transferring load from cable trays, conduit, or ductwork into the structural frame.
What materials are available?
Standard hot-dip galvanized steel is available, along with stainless steel options for food processing, pharmaceutical, and marine environments.
Are Unistrut clamp brackets corrosion resistant?
Yes. The thick zinc coating has been tested for over 500 hours salt spray test (ISO 9227) and hence is entirely corrosion-proof in outdoor and coastal surroundings.
Can Unistrut clamps support heavy loads?
Yes. They handle significant loads, with safe loads of 50–150 kg/m on P1000-series channels, depending on span and adequate spacing.
