Galvanized C Strut Channel 41×21 41×41 41×52 41x62mm HDG Slotted Channel for Solar Mounting & MEP Support
Galvanized C Strut Channel — slotted steel framing for solar, MEP, and industrial support structures.
HDG finish built for outdoor duty — the zinc coating stands up to rain, humidity, and temperature swings, keeping the channel's strength and finish intact over years of service.
One profile, six jobs — solar mounting, MEP support, electrical installations, HVAC piping, cable tray supports, and industrial framing.
Standard sizes, standard fittings — 41x21mm, 41x41mm, 41x52mm, and 41x62mm sections accept ordinary strut fittings, clamps, brackets, and accessories.
Installs fast on site — cut, position, and bolt with standard tools; no special fabrication required.

Solar Mounting Systems
Solar panel mounting rails, PV support structures, rooftop arrays, and ground-mounted systems. The whole job happens outdoors, and the galvanized finish is what keeps the channel dependable there, year after year.
MEP Engineering Support
HVAC duct supports, pipe rack systems, electrical conduit supports, cable tray installations, and mechanical equipment framing. One profile covers most of what MEP contractors hang and support.
Industrial Construction
Warehouse structures, equipment supports, steel framing systems, industrial platforms, and maintenance structures. Everyday framing jobs, handled with one standard profile.

Long Service Life
The hot-dip galvanized coating is the main reason these channels last. It resists corrosion, and that's what keeps the section in service for years.
Flexible Modular System
Works with the standard strut accessory family — channel nuts, brackets, clamps, connectors, base plates. If your crew already works with strut fittings, these channels slot straight into the same system.
Cost-Effective Installation
Lightweight sections and bolt-together assembly. Crews install with standard tools, and the savings show up where it counts — fewer hours on site.

Q1: What sizes of C strut channels do you supply?
Standard range: 41x21mm, 41x41mm, 41x52mm, and 41x62mm. Custom sizes available too.
Q2: Are these channels suitable for solar mounting systems?
Yes. Rooftop and ground-mounted solar structures are a major use case — the galvanized coating stands up to the weather, and the section carries the load.
Q3: Can you customize thickness and length?
Yes. Thickness, length, slot patterns, and dimensions can all be adjusted to the project.
Q4: What is the standard surface finish?
Hot-Dip Galvanized (HDG) as standard. Other coatings available if you need them.
