In the development of industrial storage systems, aluminium and steel composite shelving is redefining space efficiency through its innovative use of materials. By combining the exceptional strength of cold-rolled steel (with a tensile strength of Q355B ≥ 490 MPa) with the lightweight properties of aerospace-grade aluminium, we have created a high-performance shelving system that can support 3,000 kg yet weighs 40% less. This technology for combining different materials is setting new standards for storage solutions in challenging environments such as cold chain logistics, automotive production lines and data centres, from smart warehouse shelving to bacteria-resistant instrument cabinets in medical cleanrooms.

The most significant advancement in aluminium-steel composite panels is the physical connection of the materials. A 3.0 mm thick cold-rolled steel column and an 8 mm thick aluminium rod are joined at an atomic level using magnetic pulse torsion technology, achieving a shear strength of 220 MPa. For ultra-high frequency vibration scenarios, a 50 µm thick Al-Fe intermetallic composite transition layer is applied to the steel-aluminium interface using a laser, completely eliminating micro-cracks caused by differences in the thermal expansion coefficient. In the case of a food shelf, a nanorobot creates a mirror surface between the 316 stainless steel cladding and the 6063 aluminium structure that is free of microorganisms. In ultra-high-frequency vibration scenarios, a 50 µm thick intermetallic Al-Fe transition layer is laser-deposited on the steel-aluminium interface to remove microstructures caused by differences in thermal expansion coefficients. Thanks to this innovative interface, the composite platform absorbed more than 30% of the kinetic energy in an AGV crash test at a car factory, demonstrating the benefits of hybridisation in real applications, and remained structurally stable in a simulated level 8 earthquake.

To get the most out of an aluminum-steel composite hull, the physical world must be accurately represented through virtual simulation:

  • Intelligent topology optimization: The ANSYS parametric model automatically generates reinforcement designs based on the axial points of the material, increasing bending stiffness by 40% and reducing weight by 15%.

  • 12 kW filament cutting of steel sheets and waterjet spraying of aluminum profiles are performed on the same line, with a capacity of 80 tons of sheets per day.

  • Matrix for joining composite materials: 18 processes, such as friction welding, flux-cored drilling and structural joining, are integrated in one system.

  • Visualization of traceability: Each rack is equipped with a DNA material identifier that can be scanned to determine the Wechsler hardness of aluminum, the zinc layer thickness of steel, and CT micro-focus for composite joining.

Aluminium and steel composite structures have become the hidden engine of industrial modernisation:

  • It's smart storage: With steel and aluminium structures, weight can be reduced by 35%, energy consumption by 15% and speed by up to 5 m/s. Composite warehouse racking eliminates static electricity thanks to lamination with copper mesh.

  • Cleanliness: Stainless steel aluminium racks are electropolished and plasma sterilised in a cleanroom at ≤ 3520/m³ to meet GMP class A requirements.

  • Revolutionising the cold chain: Aluminium and composite steel cylinders with an impact resistance of over 85% at -40°C. The cylinder is filled with polyurethane foam to prevent thermal bridges.

  • New: Magnetic aluminium plates on a steel frame that allow you to change the layout of the display in seconds with a load of 500 kg.

Whether you need shuttle racks that can move 12 pallets per minute in an automated warehouse or instrument cabinets in a biological lab that are formaldehyde-, gas- and bacteria-resistant, aluminium and steel composite production systems push the boundaries of the laws of physics, where the strength of steel protects the lightness of aluminium and industrial rationality and material wisdom coexist at the molecular level. Symbiosis.
