BENDING RAIL

— Precision Curved Rail & Circle Rail Fabrication

Precise forming that powers track turning and intelligent industrial transport.

In rail systems, “straight” is only part of the story. Smooth metro curves, circular motion for port cranes, and flexible turns for factory hoists all rely on accurate rail bending — the core process that ensures stable, safe operation.

Glory Rail specializes in custom bending and fabrication of rails. Backed by CNC cold-bending technology and a full-process inspection system, we deliver high-precision, made-to-order curved rails (curved rail) and circle rails (circle rail) for rail transit, port machinery, industrial equipment and specialized engineering projects.

CORE TECHNOLOGY

— CNC Precision Rail Bending (Cold Bending)

Process advantages

Our CNC cold-bending technology boasts remarkable process advantages that guarantee stable quality and high precision. Ambient-temperature forming is adopted to preserve the original rail microstructure, effectively retaining the base strength and toughness of the rail without any material degradation.

With CNC control, automatic springback compensation is realised, ensuring consistent bending accuracy across all products. We also have multiple dedicated dies that can accommodate common rail profiles, including P43, P50, QU70, QU80, QU100, R65, and more. For high-precision inspection, we combine laser scanning with total station measurement, strictly controlling the accuracy within ±2 mm. Additionally, full digital traceability ensures batch stability, making each rail have consistent curvature and tight joint fit.

Optional: Thermal Bending

For very large cross-sections, very small radii, or special installation needs, we offer local hot-bending and die-assisted bending with post-heat treatment and performance testing to meet safety and service life requirements. This optional process is tailored to solve complex bending challenges that cannot be achieved by cold bending, ensuring the rails meet the highest standards in special scenarios.

CASE STUDY

Case 1 — Overseas Crane Workshop

Project: Overseas Crane Workshop in Saudi Arabia
Material: QU70 rail
Key parameters: Bend radius R = 4600 mm, total circular length 28.9 m; two 6-segment concentric upper and lower rails
Segment sizes: Upper rail – 6 equal segments (4814 ± 2 mm each); Lower rail – three sizes × 2 segments
Services provided: Custom fishplate holes, dedicated curved fishplates, integrated bending-finishing, assembly testing, anti-corrosion coating
Highlights: ±2 mm forming accuracy, ≤0.5 mm fishplate fit, smooth operation without jamming

Quality Control System

Rail safety starts with rigorous process control. We operate under ISO 9001 and strict internal controls – full traceability from incoming material to shipment. Our quality inspection covers every stage of production, as detailed below:

Stage	Inspection Items	Method	Control Standard
Incoming	Rail profile, material, straightness	Dimensional checks + visual + flaw detection	Only accepted material enters stock
Pre-bend Setup	Parameter setting, die tuning	CNC system verification	Error ≤ 1 mm
Cold Bending	consistency	CNC feedback + Curvature template comparison	Deviation within ±2 mm
Finished Inspection	Radius, flatness, surface finish	Laser scan + total station	Fully meet drawing requirements
Flaw Detection	Internal cracks, surface defects	Ultrasonic + magnetic particle testing	No cracks or defects
Packaging & delivery	Marking & Radius, batch ID	Marking records	Fully traceable

Applications & Service Scope

We support many rail profiles and sizes to meet all curved-rail needs across various industries. In railway & urban transit, we provide curved rails for metro, tram, and light rail turnouts and connections.

For port & terminal equipment, we design circular tracks suitable for gantry cranes, container cranes, and other port handling machinery. In industrial plants & bridge cranes, our product range covers arc tracks, circle rails, and suspended conveyor rails.

We also offer solutions for special scenarios, such as small-radius underground mine rails, rotating platform rails, and amusement ride rails.

From tight radii of a few metres to long, gentle arcs of tens of metres, we deliver precise forming and fit-for-assembly accuracy that meets the specific requirements of each project.

Customer Collaboration Process

We streamline our customer collaboration process to ensure efficiency and transparency at every stage, which is as follows:

Requirement & inquiry → Technical review → Drawing confirmation → Sample bending → Batch production → Inspection & acceptance → Shipment & installation support.

This process allows us to fully understand customer needs and deliver high-quality products and services in a timely manner.
