Products

Grab Pole, Handrail & Grab Handle

The Grab Pole, Handrail, and Grab Handle system ensures safety, ergonomic comfort, and rail certification for metro and EMU interiors. Made from high-strength SS304 tubular steel (Ø32 mm, 2 mm thickness, G220 buffed finish), these grab systems combine superior structural integrity, ergonomic design, and long-term durability. They offer design flexibility with multiple handle designs and color options per customer requirements, and all welding joints comply with EN 15085 railway standards. The grab handle passes a 100 kg load test for 1 hour and a 2500N static load test, with endurance proven through 100,000 swing cycles at 35 kg load. The ceiling handrail supports loads of Z: 85 kg, Y: 15 kg, and X: 25 kg. Armrest handles withstand 150 kg in both Z and Y directions, while vertical handrails are tested for X/Y load or center point loading. Tripod and grab poles handle 150 kg in X/Y and 200 kg in Y direction at the center. The side screen option includes 6 mm tempered glass, tested for fragmentation and drop safety.

These grab systems are used in metro and EMU coaches to enhance passenger safety and stability. In metro coaches, they serve as handholds and vertical/horizontal supports for safe standing travel. In EMU coaches, they act as durable grab poles and handrails, improving interior safety and reliability. Overall, these products deliver a customizable, long-lasting solution for modern rail interiors under demanding transit conditions.

Aluminium Sandwich Floor Board for Rail Car Body

The Aluminium Sandwich Floor Board for Rail Car Body is a lightweight, rigid, and high-performance flooring solution engineered for superior strength, stability, and durability. Constructed with a high-strength aluminium honeycomb core, it provides excellent stiffness with minimal weight, making it ideal for next-generation metro, commuter, and high-speed train applications. The panels are fully compliant with EN 17460 bonding standards for structural integrity, and all welding joints meet EN 15085 standards for railway components. The structure offers exceptional corrosion resistance, ensuring long life and protection against oxidation and wear. Each panel is currently undergoing rigorous testing and validation for load, vibration, and environmental performance to guarantee long-term reliability.

These aluminium sandwich panels are designed to improve overall efficiency, safety, and comfort across various rail sectors. In metro coaches, they serve as lightweight floorboards that enhance energy efficiency and long-term durability. For commuter trains, the panels provide superior load-bearing strength and vibration resistance, ensuring a stable and quiet ride. In high-speed trains, the advanced sandwich construction offers stable, safe, and long-lasting flooring systems, supporting high performance under demanding operating conditions.

Aluminium Honeycomb Seat for Metro

The Aluminium Honeycomb Seat for Metro is a next-generation seating system designed for lightweight durability, safety, and comfort. Built with aluminium honeycomb technology, it provides superior structural strength while significantly reducing weight — a 7-seater configuration weighs only 35 kg. The seat is load-tested with bi-directional push and pull forces of 15 kg on movable parts, simulating a 70 kg passenger with 10% applied force. It meets NFF 31119 standards for fatigue and vibration performance and all welding joints comply with EN 15085, while adhesive bonding conforms to EN 17460 standards. For fire safety, it integrates HL3 Foam & Trim certified to EN 45545-HL3. The design offers flexibility with 2-seater, 5-seater, and 7-seater configurations to suit various rail interior layouts.

Engineered for passenger comfort and compliance with international rail standards, this seating system is ideal for metro and EMU applications. In metro coaches, it serves as a lightweight, high-capacity seating solution that enhances efficiency and ease of installation. For Electric Multiple Units (EMUs), it provides a fire-safe, durable, and low-maintenance option that supports long-term operational reliability.
