Frequently Asked Questions
Q
What materials are strut channel accessories available in?
Strut channel accessories are available in a range of materials including mild steel/carbon steel, pre-galvanized steel, hot-dip galvanized (HDG) steel, stainless steel (304 and 316 grades), PVC-coated steel, and fiberglass composite. Each material is suited to different environmental and load requirements.
Q
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 environments, 316 grade stainless steel provides maximum corrosion resistance. Fiberglass composite is also a strong choice for saltwater and chemical exposure due to its non-conductive, corrosion-resistant properties.
Q
Are strut channel accessories compatible across different manufacturers?
Yes. All accessories are designed to work with standard 41×21 mm and 41×41 mm strut channel profiles, ensuring interchangeability across most manufacturers. This modular compatibility simplifies procurement and installation on mixed-brand projects.
Q
Do I need special tools to install strut channel accessories?
No special tools are required. Components assemble with standard hand tools and no welding or drilling is needed. Channel nuts and spring nuts slide into the channel lips and lock in place when tightened, making installation fast and straightforward.
Q
What types of brackets are available for non-standard angle connections?
For non-standard angle connections, obtuse brackets are available in adjustable angles including 30°, 45°, 60°, 120°, 135°, and 150°. Swivel brackets also offer flexible adjustable-angle positioning to accommodate irregular frame configurations.
Q
What accessories are recommended for seismic or high-vibration environments?
For seismic applications, seismic bracing connectors (hinged connectors for earthquake bracing) and adjustable braces (diagonal bracing components) are recommended for code-required seismic restraint systems. In high-vibration environments, vibration-damping clamps and rubber profiles/insulators help absorb shock and reduce noise transmission.
