What is the standard length for DIN 536 A55 crane rail?
The standard length for the DIN 536 A55 crane rail typically 12 meters, though 12-meter sections are the most common international shipping standard. Because these rails are designed for high-load industrial tracks, providing them in specific lengths helps minimize the number of joints, which reduces mechanical wear on crane wheels. For large-scale infrastructure projects, GNEE RAIL customized lengths such as 15 meters or even 18 meters can be produced to meet specific engineering requirements.
- Standard Stock Lengths: 12m.
- Custom Length Range: 6m to 18m (upon request).
- Tolerance: Precise length tolerances are maintained according to the DIN 536-1991 A55 crane rail standard to ensure seamless alignment during installation.
GNEE RAIL utilizes advanced automated cooling and straightening beds to ensure that every A55 rail profile, regardless of length, maintains a straightness tolerance of 1:1000 or better. Our facility is equipped to handle heavy-duty cutting and drilling to provide ready-to-install A55 crane tracks, which are then secured using moisture-proof packaging and specialized sea-freight bundling to prevent deformation or oxidation during international transit.
Why use standard-length A55 crane rail profiles?
Standard-length (typically 12-meter) A55 crane rail profiles (DIN 536) are used primarily to ensure structural compatibility, facilitate easy installation, and maintain high performance in light-to-medium duty overhead crane systems. They are designed to DIN 536 standards to provide a stable, durable track for crane wheels, often used in workshops, storage facilities, and small ports.
Key Reasons to Use Standard-Length A55 Rails:
- Standardization and Compatibility: The DIN 536 A55 profile is produced to a strict standard with a 55mm head width and 150mm base width. Using this standard ensures it integrates perfectly with standard fastening systems, fishplates, and crane trolley wheels.

- Optimal Load Distribution: The 150mm wide base and 31mm thick web are designed specifically for moderate wheel loads in light-duty industrial applications (such as in warehouses), offering better load distribution than smaller, non-standard rail options.
- Ease of Installation and Handling: The 12-meter standard length is practical for transport, handling, and installation on both steel and concrete support structures.
- Ready Availability: As standard products, A55 rails are readily available and can be quickly supplied.
How are standard-length A55 steel rails transported?
Standard-length A55 crane rails (DIN 536), which are typically 12 meters or custom lengths, are transported using specialized logistics to ensure the rails are not damaged and remain straight. They are commonly moved via road, rail, or sea in bundled, secured units.
Primary Transportation Methods
- Truck/Road Transport: For short to medium distances, rails are loaded onto trucks. For maximum efficiency, full-truck loads are often used, with capacities up to 40 metric tons.
- Railway Freight: For long distances, rails are transported via specially designed freight trains.
- Container Shipping: For international or long-distance shipping, A55 rails are bundled and loaded into containers for transport by vessel, often protected by 0.5.2 moisture-resistant film. 40-foot standard containers (or 40ft High Cube containers) are the most suitable size for transporting standard-length A55 crane rails, as these rails are typically produced in 12-meter lengths. A 40ft container has an internal length of approximately 12.03 meters, offering a precise fit for 12-meter (approx. 39.4 ft) rails.
FAQ
1. Can A55 crane rails be cut to a specific length of 5.8 meters for small workshops?
Yes, we provide precision cutting services for the A55 rail profile. Cutting to 5.8 meters is common for small workshop installations or for fitting into smaller shipping containers when specialized lifting equipment is not available at the destination.
2. How does the length of the rail affect the number of clips needed?
The number of standard fastening clips is determined by the "clip spacing" (usually every 500mm to 600mm), not the rail length itself. However, longer rails reduce the number of joint sets and fishplates required for the overall DIN 536 A55 rail system.
3. Is there a maximum length for A55 rails due to thermal expansion?
While we can produce long sections, thermal expansion must be managed. For very long continuous runs of A55 heavy rails, we recommend using Alumothermic Welding kits for Rails combined with flexible clips and pads to allow the rail to expand and contract without buckling.
4. Does the weight of the rail change if I choose a higher material grade like S900Q?
No, the A55 rail weight per meter remains approximately 31.8 kg/m regardless of the grade. The A55 Crane Rail Material Grade changes the chemical composition and strength, but the physical DIN A55 Rail Dimensions and density remain consistent.
