Structural Beam Connection Systems
Beam connection systems are essential structural components used to connect beams with columns, supporting frames, foundations, and modular structures. Their performance directly affects structural alignment, load transfer reliability, and installation efficiency during construction.
We manufacture beam connection systems for structural steel contractors, distributors, fabricators, and industrial construction suppliers worldwide. Our products are produced according to engineering drawings, CAD models, and project specifications, providing reliable solutions for bolted connections, welded joints, beam splices, and customized structural assemblies.
With integrated capabilities in steel fabrication, CNC machining, precision drilling, welding, and surface treatment, we support both standard production and OEM manufacturing requirements for bulk orders.

Product Categories & Structural Connection Types
Beam-to-Column Connections
Designed to transmit shear forces, axial loads, and bending moments between horizontal framing members and vertical supports.
• Moment Connections: Fully welded or heavy bolted flange connections for lateral force resistance.
• Shear Connections: Single-plate (fin plate), double-angle, and seated connections engineered for vertical load transfer.
• Bolted Brackets & Seats: Precision-punched or drilled brackets for fast field alignment.
Structural Connection Plates & Gussets
Essential plate components used to stabilize frames, transfer localized stresses, and tie bracing members.
• Gusset Plates: Custom geometric profiles for truss joints and cross-bracing.
• Base & Anchor Plates: Heavy steel plates prepared for anchor bolt layout and leveling.
• Stiffener & Tie Plates: Factory-cut reinforcement plates for web buckling prevention.
Splice Connection Systems
Engineered for joining structural beams along extended spans or facilitating transport/erection limits.
• Flange & Web Splice Plates: Sized and drilled to match mill tolerances of rolled shapes (I-beams, H-sections, W-shapes).
• End Plate Connections: Flush or extended end plates machined flat for tight bearing contact.
Modular & Prefab Framing Connectors
High-repeatability connectors designed for rapid, low-labor assembly in off-site and modular construction.
• Inter-Modular Connectors: Corner castings and locking plates engineered for stacked module alignment.
• Self-Locating Beam Seats: Tapered or pinned connections that reduce on-site crane time.

Surface Finishing & Corrosion Mitigation
Proper surface preparation is mandatory to achieve intended coating performance and field lifespan.
Hot-Dip Galvanizing (HDG)
Processed according to ISO 1461 or ASTM A123. Provides thick zinc protection (610 g/m² standard minimum) for exposed outdoor steelwork.
Blast Cleaning
Abrasive blast cleaning to ISO 8501-1 Sa 2.5 standard prior to coating application.
Industrial Paint Coatings
Zinc-rich epoxy primers, intermediate coats, and polyurethane topcoats applied under temperature/humidity-controlled environments.
Quality control is integrated into every phase of production rather than handled as a final gate.
