Thicknesses ranging from 0.3mm to 3.0mm of 'steel cookies' are currently enjoying their moment in the spotlight. Home appliance giants are rolling them into refrigerator exteriors, new energy vehicle manufacturers are pressing them into battery trays, and even smart lockers are using SPCD cold-rolled steel sheets for their designs. A workshop technician joked: 'Today's steel is like Gen Z, needing a smooth surface and high aesthetics while also being able to withstand pressure, tension, and fatigue, living a more intense life than us blue-collar workers.'"
"Different from the aloof stainless steel siblings, cold-rolled carbon steel rolls take an 'economic and practical' route. Members of the low-carbon steel family, such as Q195 and Q235, come with inherent accessibility, transforming into 'Transformers' in the construction industry and 'Sakura' in hardware stores. A dealer revealed: 'Recently, cold-rolled sheets made of 08Al material have been particularly popular, supposedly preparing for the smart home appliance battle during 618.'"
Steel mill technicians have developed a new rolling lubrication system, calling it a 'SPA for steel.' In the workshop, the acid washing line hums 'The Steel Tide March,' the annealing furnace dances a waltz, and even quality inspectors joke about 'three-no' standards: no pitting, no scratches, and no social anxiety. A 90s engineer stated: 'We are developing customizable patterned cold-rolled sheets; in the future, your anti-theft door might come in leopard print or Morandi color schemes.'
According to insiders, cold-rolled
Carbon Steel Coils under the JIS G3141 standard have evolved into 'hexagon warriors': meeting the stringent demands of structural steel in construction while also fulfilling the meticulous standards of precision instruments. However, a seasoned workshop master warned: 'You'll regret not ordering enough steel when you need it; I suggest all project managers place orders early since our steel production speed can't keep up with ChatGPT's coding speed.'
