Why Hong Kong uses bamboo scaffolding, and meet the spider-men who climb it: a visual explainer – South China Morning Post

Hong Kong is one of the last places in the world where bamboo is still widely used for scaffolding in construction. It’s flexible, strong and cheaper than steel and aluminium — metal alternatives that are now more commonly used in mainland China and elsewhere in Asia. In Hong Kong, skilled armies of scaffolders can erect enough bamboo to engulf a building in a day — even hours — using techniques that are thousands of years old, and have been passed down through generations.
