The DIN 536 A serie is recognized globally for its wide-flange design. These European A sections low profile rails (often historically referred to as Burbach Rail A120 or simply "A" type rails) are designed specifically for crane runways rather than train tracks.

 

 

 

The Profile A120 rail features a lower height and a wider base compared to traditional railway tracks, effectively distributing the immense wheel loads from heavy crane wheels down to the foundation.

 

 

The A120 rail is a heavy-duty crane rail manufactured according to the DIN 536 P1:1991 standard, featuring a weight of 100 kg/m. It is designed for high-load, high-frequency industrial environments with dimensions including a 105 mm height, 120 mm head width, and 220 mm base width.

 

 

Rail Type	Weight(Kg/m)	Material	Length(m)
A120	100	700/900A/1100	10-12
Head Width(mm)	Bottom Width(mm)	Rail Height(mm)	Web Thickness
120	220	105	72

The performance of the A120 rail profile is fundamentally defined by its steel grade. To meet diverse operational requirements-from standard industrial tracks to extreme-load port terminals-we provide DIN 536 A120 rails in three primary material categories.

 

GNEE RAIL offer high-quality manufacturing equivalents (GB Standard) that align strictly with the mechanical properties defined by DIN 536-1:1991.

 

• S700 (Standard Grade): The most commonly used grade for A45~A150, providing sufficient strength for most applications.

 

• S900: Higher grade for A75~A150, used for more demanding applications.

 

• S1100 : Chrome-vanadium alloy steel, offering maximum strength, hardness and resistance to wear.

 

 

DIN 536 Grade	Tensile Strength (Min.)	GB Equivalent Grade	Recommended Application
Grade 700 (R700)	≥690 N/mm²	50Mn / U71	Light to medium-duty industrial overhead cranes.
Grade 900A (R900)	≥880 N/mm²	U71Mn	Standard high-frequency heavy-duty crane tracks.
Grade 1100 (R1100)	≥1080 N/mm²	U75V	Ship-to-Shore (STS) cranes and extreme load capacities.

 

 

Grade 1100 (U75V)

 

For the A120 heavy rails used in high-capacity port projects, Grade 1100 is the industry benchmark.

 

Composition Advantage: Utilizing the U75V equivalent ensures a Vanadium-alloyed structure, providing superior wear resistance and a minimum tensile strength of 1080 N/mm², essential for the massive footprint of Burbach Rail A120.

 

Steel Grade	C (%)	Si (%)	Mn (%)	Cr (%)	V (%)	P (%)	S (%)	Tensile Strength (Rm/MPa)
Grade 1100	0.60–0.82	0.30–0.90	0.80–1.70	-	-	≤0.035	≤0.035	≥1080
U75V	0.71–0.80	0.50–0.80	0.70–1.05	-	0.04–0.12	≤0.030	≤0.030	≥1080

 

Grade 900A (U71Mn)

 

The most common choice for A120 steel rails, offering an optimized balance between ductility and hardness. The U71Mn chemistry provides excellent weldability for Alumothermic Welding kits, ensuring seamless joints across long crane tracks.

 

Steel Grade	C (%)	Si	Mn	Cr	V	P	S	Tensile Strength (Rm/MPa)
U71Mn	0.65~0.76	0.15~0.58	0.70~1.40	–	–	≤0.035	≤0.030	≥880
900A	0.60-0.80	0.10-0.50	0.80-1.30	–	–	≤0.040	≤0.040	≥880

 

Grade 700 (50Mn/U71)

 

DurabilityIdeal for applications where load frequency is lower, yet the stability of the A120 rail dimensions is still required. These A120 rails provide reliable service for general industrial warehouses and assembly lines.

 

Steel Grade	C (%)	Si	Mn	Cr	V	P	S	Tensile Strength (Rm/MPa)
50Mn	0.48-0.56	0.17-0.37	0.70-1.00	0.25	–	≤0.035	≤0.035	≥645

 

GNEE RAIL conduct strict ultrasonic testing on all our A120 steel crane rail materials to ensure there are no internal flaws before shipment.

 

 

A120 crane rail (DIN 536) is a heavy-duty steel rail, weighing 100 kg/m, designed for high-capacity lifting and transportation. It is primarily used for gantry cranes in ports and shipyards, overhead cranes in steel mills, automatic stacker cranes in warehouses, and heavy-duty machinery in industrial manufacturing sites.

 

• Port and Container Terminals: The A120 rail is a standard choice for Ship-to-Shore (STS) cranes and Rail Mounted Gantry (RMG) cranes. Its wide surface area ensures stability when moving heavy shipping containers across dockside tracks.

 

• Heavy Industrial Manufacturing: Inside steel mills, foundries, and automotive plants, overhead bridge cranes use A120 rails to transport raw materials and finished products like steel coils or engine blocks.

 

• Shipbuilding and Repair: Gantry cranes in shipyards rely on the A120 profile to manage the extreme weight of hull sections and heavy marine components during vessel assembly.

 

• Hydropower and Dam Maintenance: Large-scale dams use these rails for the operation of gate cranes, which are responsible for lifting and lowering heavy floodgates or maintaining turbines.

 

• Warehouse and Logistics Hubs: For automated storage and retrieval systems (AS/RS) that handle oversized or heavy palletized goods, the A120 provides a rigid, long-lasting track solution.

 

Complete A120 rail accessories comprise high-strength components designed for DIN 536 heavy-duty crane systems, including forged rail clamps (welded or through-hole), elastic EVA rubber pads, fishplates (joint bars), bolts, nuts, and base plates. These accessories ensure stability, wear resistance, and vibration dampening for crane rails in ports and industrial applications.

 

To ensure the longevity of your A120 overhead crane rail systems and minimize maintenance, you need the right crane components. GNEE RAIL supply a comprehensive range of A120 rail accessories,our track accessories include:

 

• Standard Fastening Clips: Weldable or bolted clips designed specifically for the A120 rail profile.

 

• Rubber Pads: Continuous resilient elastomeric pads placed under the rail to reduce vibration and prevent wear.

 

• Baseplates / Steel Soleplates: High-strength steel plates used to support the DIN standard rails on concrete foundations.

 

• Alumothermic Welding Kits for Rails: We provide thermite welding powder, crucibles, and molds for seamless jointing of A120 rails, creating a continuous track.

 

Q1: What does "A120" mean in the DIN 536 standard?

A: In the DIN 536 Standard Crane Rail specification, the "A" denotes the specific low-profile crane rail shape, and "120" refers to the width of the rail head in millimeters (120mm).

 

Q2: What is the difference between A100 and A120 crane rail?

A: The main difference lies in the dimensions and weight. The A120 rail has a 120mm head width and a DIN A120 Rail Weight of 100.2 kg/m , making it suitable for heavier wheel loads compared to the A100 rail, which has a 100mm head and weighs 74.3 kg/m .

 

Q3: What is the main benefit of the "A" type rails like A120?

A: "A" type rails feature a squat, wide design that provides superior lateral stability and allows for lower mounting heights in A120 overhead crane rail systems.

 

Q4: Can you provide A120 rails in specific lengths?

A: Yes, while the DIN standard stock lengths are 10m-12m, we offer precision cutting to meet your specific A120 Crane Rail layout requirements.

 

Q5: Can you supply the complete A120 Rail System?

A: Yes, we provide the complete package. Besides the steel rails, we supply crane track accessories including standard fastening clips, rubber pads, baseplates/Steel Soleplates, and welding materials.

 

Q6: Do you offer international shipping for Heavy Rail DIN 536 A120 Rail?

A: Absolutely. We specialize in the logistics of A120 heavy rails, ensuring they are packed to prevent corrosion and bending during sea freight.
