Frequently Asked Questions
Q
What materials are strut channel accessories available in?
Strut channel accessories are available in mild steel (plain or electro-galvanized), pre-galvanized steel (G-90), hot-dip galvanized (HDG, ASTM A123), stainless steel (304 or 316 grade), PVC-coated, and fiberglass composite. Each material suits different environments — from standard indoor use to marine or chemical exposure.
Q
What is the difference between a channel nut and a T-head bolt?
A channel nut (or spring nut) is a square nut with serrated grooves that grips the channel lips when tightened — it is the primary fastening element. A T-head bolt has a specially shaped head that slides within the channel profile itself, and is commonly used to attach pipe clamps and other accessories directly to the channel body.
Q
Are strut channel accessories interchangeable across different manufacturers?
Yes. All standard strut channel accessories are designed to be compatible with both 41×21 mm (half-slot) and 41×41 mm (square) channel profiles regardless of manufacturer. This ensures flexibility when sourcing components from multiple suppliers on the same project.
Q
Which finish should I select for outdoor or corrosive environments?
For outdoor or moderately corrosive environments, hot-dip galvanized (HDG) per ASTM A123 offers excellent long-term protection. For marine environments, chemical plants, or saltwater exposure, 316 stainless steel or fiberglass composite provides the highest corrosion resistance. PVC-coated options work well in high-vibration environments where mechanical wear is a concern.
Q
Can strut channel systems be installed without welding or drilling?
Yes. A key advantage of strut channel systems is that no welding or drilling is required. Components are secured using channel nuts, T-head bolts, and standard hand tools. Beam clamps additionally allow direct attachment to structural steel overhead without any drilling, making installation significantly faster and more adaptable to site conditions.
Q
What accessories are recommended for seismic or heavy-load applications?
For seismic applications, seismic bracing connectors (hinged) and adjustable diagonal braces are engineered to meet code-required seismic restraint requirements. For heavy-load scenarios, corner gusset brackets, girder clamps, beam clamps with U-bolts, and C-FIX nuts/washers deliver reinforced, heavy-duty connections suited to industrial framing and high-stress structural applications.
