Hong Kong uses over 5 million bamboo poles each year as scaffolding materials, primarily for building maintenance, renovation, and new projects. Each bamboo pole is about 6-7 meters long and has a diameter of 40-75mm (bamboo or moso bamboo), with an age of 3-5 years, and can be reused 2-3 times after being air-dried. These bamboos are mainly imported from Zhaoqing in Guangdong, Guangxi, and Vietnam, accounting for 70-75% of all building auxiliary materials in Hong Kong. Industry associations estimate this translates to an annual consumption of about 30,000-40,000 tons of bamboo (considering the reuse rate), with a total value of about 100-200 million Hong Kong dollars. Starting in 2025, the Hong Kong government will mandate that 50% of public works use steel frames, with an expected total transformation cost of about 1-2 billion Hong Kong dollars over five years. The total number of scaffolding workers in Hong Kong is about 5,000-6,000, with around 3,000-4,000 specializing in bamboo scaffolding (the majority being workers over 50 years old, passed down through generations), which may lead to transformation or unemployment for related manual workers in the future. In March 2024, as the real estate industry in mainland China continues to decline, the total production capacity of cuplock scaffolding manufacturing enterprises is about 17.5 million tons, with an actual output of only 4.7 million tons, resulting in a utilization rate of only 27%, indicating a significant oversupply issue. By 2025, the production capacity is expected to shrink slightly to below 10 million tons (due to the shutdown of small and medium-sized enterprises), but it will still far exceed demand.
