Which Material Grade Should You Choose for A120 Rail?
Choosing the right grade comes down to wheel load and duty cycle. S700 handles general runways; 900A (U71Mn) is the go-to for port cranes; S1100 is for the heaviest, highest-wear applications. Full mechanical and chemical data below
General Duty
S700
Most Popular
900A (S900A)

Where Is A120 Crane Rail Used in Heavy Industry?
01 — Container Terminals
STS and RMG cranes
A120 is well suited to heavy-duty crane tracks in container terminals, where high wheel loads and frequent crane movement require a rail with a wide base and strong load-bearing capacity.
02 — Steel Mills & Foundries
Charging cranes, ladle cranes, overhead cranes
In steelmaking and foundry operations, crane rails are exposed to high wheel loads, impact and demanding working conditions. A120 provides a robust running surface and broad base for heavy industrial crane tracks.
03 — Shipyards & Dry Docks
Gantry cranes, heavy lifting systems
A120 can be used for heavy gantry crane tracks in shipyards and dry docks, where large crane loads and long track spans place greater demands on rail stability and load distribution.
04 — Hydropower & Heavy Industry
Heavy-duty overhead and gantry cranes
For hydropower plants and other heavy industrial facilities, A120 provides a suitable track rail for cranes handling large components such as turbines, generators and other heavy equipment.
How Does Glory Rail Guarantee A120 Rail Quality?

A120 Crane Rail: Common Questions
Which A120 material grade should I choose: S700, 900A, or S1100?
Use S700 (≥690 N/mm²) for general and medium-duty crane runways; 900A/U71Mn (≥880 N/mm²) as the standard heavy-duty choice for port and industrial cranes; and S1100 (≥1080 N/mm²) only for extreme wheel loads or high-wear environments. 900A is the most common selection for A120 because it balances strength, hardness (~260–300 HBW), and cost. See the material grade comparison above.
What is the difference between A100 and A120 crane rails?
A100 has a 100mm head and weighs ~74.3 kg/m; A120 has a 120mm head and weighs 100 kg/m. A120 is specified for larger wheel loads, wider wheels, and heavier port or shipyard cranes, while A100 can suit medium-duty overhead or gantry cranes. If your STS crane lifts 65 t or more, A120 is the safer specification.
How does DIN 536 A120 compare to GB QU120 and AREMA standards?
DIN 536 A120 has a 220mm base and 105mm height — a squat, laterally stable profile. GB QU120 is taller at 170mm with a 170mm base, optimized for vertical bending; the two are not interchangeable in fasteners, pads, or sole plates. AREMA/ASCE are railway standards, not direct crane-rail equivalents. For international port projects, DIN 536 A120 is usually preferred for its lateral stability and wide base.
What quality certificates and testing come with exported A120 rails?
Each rail carries a Mill Test Certificate to EN 10204 Type 3.1/3.2 with heat-number traceability. Inspection includes ultrasonic testing (UT), magnetic particle inspection (MPI), and visual check. Mill reports cover chemical composition, tensile strength, hardness, and elongation. Third-party inspection by SGS, BV, or TÜV is welcome at any stag
How is A120 crane rail shipped internationally and which incoterms apply?
Standard 6–12m rails usually ship by breakbulk sea freight in bundles with seaworthy packaging. Common incoterms include FOB, EXW, CFR, CIF, and DDP, with lead times around 7–30 days after payment. Typical Chinese loading ports are Tianjin and Qingdao. For exact freight to your port, request shipping details.
