Rail Splices & Connectors: Structural Continuity & Thermal Expansion Guide
Rail splices join profile bars across long module strings, ensuring continuous bending moment distribution while allowing engineered thermal expansion joints.
4 Key Engineering Selection Criteria for Rail Splices & Structural Connectors
Internal Slide-In vs External Splice
Internal splices hide inside rail chambers preserving clear top/bottom channels; external splices provide extra shear support for heavy snow regions.
Thermal Expansion Joint Gaps
Recommended every 12 to 15 meters with expansion connectors to prevent thermal rail buckling.
Self-Drilling Screw Locking
Secured firmly with bi-metal stainless screws through pre-marked alignment slots.
Electrical Continuity Bridging
Compatible with copper bonding jumpers for uninterrupted grounding across spliced rail rows.
Export Pricing & Logistics Procurement Tips
Splice connectors are supplied in cartons of 100 pcs. Internal slide-in models are pre-cut to 150mm–200mm lengths.
