FAQs
Q: What are welded rail clips used for?
Welded rail clips are permanent rail fastening components used to secure crane rails to steel support beams. They are welded directly to the beam flange, holding the rail base firmly in place. These clips are commonly used in:
- Overhead crane runway beams in industrial facilities
- Port and shipyard crane tracks
- Steel mill and foundry crane rails
- Heavy-duty material handling systems
ForgeSail welded rail clips are engineered to handle dynamic loads, thermal expansion, and continuous operation in demanding environments.
- Continuous welded rail (CWR) joints in railway construction
- Crane rail welding in steel mills, ports, and shipyards
- Metro and tram line track installation
- Industrial track maintenance and repair
ForgeSail's aluminothermic welding kits are designed for field use — no external power required, portable, and capable of delivering strong, permanent welds in under 30 minutes per joint.
Q: What's the difference between welded and bolted rail clips?
The main difference is the installation method and adjustability:
- Welded rail clips are permanently welded to the steel beam — no drilling required, no loose parts, zero maintenance after installation. Best for permanent installations with stable alignment.
- Bolted rail clips are fastened with bolts, allowing adjustment and realignment. Better for tracks that may need future realignment or relocation.
ForgeSail offers both types. Welded rail clips are preferred for new installations in steel mills, ports, and heavy industrial facilities where alignment is finalized and maximum rigidity is needed.
Q: What rail profiles are compatible with welded rail clips?
ForgeSail welded rail clips are available for the following rail profiles:
- A-section crane rails: A75, A100, A120, A150 (DIN 536 standard)
- QU series rails: QU70, QU80, QU100
- Railway rails: UIC 60, UIC 54, AREMA 115RE
We also offer custom-sized clips for special profiles. Contact us with your rail specification and we can provide the matching clip.
Q: How are welded rail clips installed?
Installation of welded rail clips follows these steps:
- Position the rail on the steel beam with correct alignment and gauge
- Place the welded rail clips at specified intervals (typically 500-600mm centers)
- Tack weld the clips to the beam flange to hold position
- Check rail alignment and adjust if needed
- Apply final full weld according to welding procedure specification
- Allow to cool — no torque checking needed
ForgeSail provides a welding procedure guide with every order. We recommend qualified welders follow AWS D1.1 or equivalent standards.
Q: What materials and finishes are available for welded rail clips?
Our welded rail clips are manufactured from:
- Material: Q235B / SS400 structural steel (standard), S355 / 55C high-strength steel (optional)
- Standard finish: Hot-dip galvanized (minimum 80μm coating thickness)
- Optional finishes: Plain (for on-site welding and painting), epoxy painted, zinc-rich coated
Hot-dip galvanized finish is recommended for outdoor or high-humidity environments (ports, mining, shipyards). Our standard clips are tested for clamping force and dimensional accuracy before shipment.
