As September arrives, primary and secondary schools both domestically and internationally are gradually reopening. According to a report by the British Broadcasting Corporation (BBC), the UK government has issued orders to close over 100 schools due to safety concerns related to the construction material used, known as Reinforced Autoclaved Aerated Concrete (RAAC), which poses a risk of sudden collapse. Faced with this challenge, Hunan Yaheng Tengfei, a manufacturer of prefabricated classrooms, has stepped forward to provide a viable solution for addressing the government's safety requirements, including the use of foldable container classrooms as the preferred choice.
