Frequently Asked Questions

1 What materials are strut channel accessories available in?

Strut channel accessories are available in a wide range of materials including Mild Steel / Carbon Steel (plain or electro-galvanized), Pre-Galvanized Steel (G-90), Hot-Dip Galvanized Steel (ASTM A123), Stainless Steel (304 or 316 grade), PVC Coated, and Fiberglass composite. Each material is suited to specific environmental conditions and corrosion resistance requirements.

2 Which finish should I choose for outdoor or marine environments?

For highly corrosive exterior environments, Hot-Dip Galvanized (HDG) per ASTM A123 is recommended. For marine or chemical exposure, 316-grade Stainless Steel offers the maximum corrosion resistance. Fiberglass composite is also a suitable non-conductive option for chemical and saltwater environments.

3 Are strut channel accessories compatible across different manufacturers?

Yes. All accessories are designed to be compatible with standard 41×21 mm and 41×41 mm strut channel profiles, ensuring interchangeability across most major manufacturers. This modular design allows for flexible sourcing and consistent system performance.

4 Do I need special tools to install strut channel accessories?

No special tools are required. All components are designed for assembly using standard hand tools. There is no need for welding or drilling, which significantly reduces installation time and labor costs on-site.

5 How do channel nuts prevent loosening under load?

Channel nuts (also called spring nuts) feature serrated teeth on their bearing surface. When tightened, these teeth bite into the inward-facing lips of the strut channel, creating a mechanical lock that resists rotation and loosening even under dynamic or vibrating loads.

6 What accessories are recommended for seismic bracing applications?

For seismic bracing, Seismic Bracing Connectors (hinged connectors designed for earthquake restraint) and Adjustable Braces (diagonal bracing components) are the primary components used. These accessories meet code-required seismic restraint standards and provide structural reinforcement against wind and seismic forces.
