SUS304 & HDG Steel Bracket Fittings

SUS304 & HDG Steel Bracket Fittings

Industrial-grade solar strut channel connectors and bracket fittings engineered for seamless integration with standard 41x41mm C-channels and PowerCableTray networks. Available in heavy-duty Hot-Dip Galvanized (HDG) steel (zinc coating ≥85μm) and premium SUS304/SUS316 stainless steel. These pre-punched, bolt-on corner brackets, splice plates, and beam clamps completely eliminate on-site welding, ensuring rapid installation and ultra-secure load distribution for utility-scale solar farms and heavy cable management systems.

    • 90-Degree Angle Brackets: L-shaped corner connectors (2-hole to 4-hole) for rigid structural framing.
    • Strut Joiners & Splice Plates: External and internal sleeve connectors for extending C-channel lengths.
    • Heavy-Duty Beam Clamps: Window/虎口 window clamps for securing solar structures to structural steel H-beams without drilling.
    • Channel Nuts & Hardware: Stainless steel and HDG spring nuts, washers, and hexagon bolts for secure locking.


Applications
    • Solar PV Racking Systems:Connects posts, beams, and rails securely across ground-mount or commercial rooftop projects.
    • Cable Tray Support Networks:Acts as the core heavy-duty joints for overhead, wall-mounted, or under-floor cable tray trapeze hangers.
    • Industrial Pipe & Conduit Supports:Provides versatile, modular grid framing for complex industrial wiring and piping systems.


Packaging & Shipping
    • Bulk Cartons: Connectors and fittings are packed in heavy-duty, moisture-proof corrugated boxes.
    • Palletized Delivery: Boxed items are stacked on export-standard fumigated wooden or steel pallets, wrapped in stretch film for ultimate maritime transit protection.


Why Buy Connectors from PowerCableTray?
    • Perfect Tolerance Match: Buying channels and connectors from the same manufacturer ensures a 100% flush fit without loose gaps.
    • Burr-Free Engineering: All edges are deburred and smoothed to prevent injury during installation and protect routed cables from scratching.
    • Project Scale Pricing: Direct factory manufacturing gives you the strongest B2B wholesale pricing on bulk orders.
