In modern industrial buildings and infrastructure systems, steel columns can support loads of up to 10,000 tonnes, forming an essential part of the building's foundation. Using precision sheet processing technology, we forge cold rolled steel through a manufacturing trilogy that includes laser cutting, CNC forming and full penetration welding. This process turns Q355B steel into strategic structural elements that support industrial facilities, logistics centres, stadiums and power plants. These silent steel shafts protect the functional landmarks of human industrial civilisation with millimetre precision when wind turbine towers must withstand a 14-degree hurricane or automated warehouses must withstand three-dimensional loads of 12 tons per square metre.
To optimize the performance of structural steel columns, the quality of the steel must first be carefully controlled. Box columns, which are made of 100-mm-thick plates, are used for heavy-duty applications. They are laser cut, and their internal longitudinal deflectors are designed to prevent local deformation. This allows them to withstand loads of up to 8,000 kN or more. The arena's curved columns have a variable cross-section (wall thickness: 16–40 mm), and the double-curved arches meet the seismic requirements of EN 1993 using digital bending control (bending radius deviation: ≤1.5 mm/10 m). The columns of the offshore platform are laser-coated with a nickel 625-based alloy on a Q420 steel plate base and can withstand 30 mm of bending. This combination of materials and geometry enables a single production system to manufacture 1,200-mm-long columns for wind turbine towers, as well as decorative, lightweight steel columns for villas with a wall thickness of only 6 mm. This balance of rigidity and aesthetics is ideal for both applications.
The modern metal prop is the perfect combination of the virtual and the real：Machining codes are automatically generated based on the BIM model (e.g. hole coordinates for a group of bolts on the leg of the support), eliminating traditional placement errors. A 400A plasma cutter with extremely limited capacity cuts 80 mm-thick sheet metal, while a 120-tonne CNC bender creates complex reinforcements. A gantry welding centre performs continuous welding on an extra-long 25 m beam with constant parameters. The unique ultrasonic flaw detection system achieves a success rate of ≥99.7%.
Steel columns have played a key role in all of humanity's technological advances：An automatic loading column for a fixed warehouse has been topologically optimised to reduce steel consumption by 18%. A 50 m racking system has withstood a 200,000 AGV impact test. A hospital building uses composite columns with curvature-limiting supports, and their energy dissipation capability has been verified in a static test, ensuring the building's stability during an earthquake. The floating platform columns use non-explosive composite technology combining duplex S31803 stainless steel and carbon steel, maintaining structural integrity during a 100-year storm in the North Atlantic.
From building earthquake-resistant columns to support 100 tonnes of UPS equipment for a data centre to constructing a steel support system for a polar research station operating at -50°C, the modest steel column system defies gravity. Each weld is a faithful interpretation of structural logic and each column represents an ongoing quest for spatial order.
