Я думаю, что в переводе их можно разделить на prefabricated или просто standard и custom-designed/project-specific scaffolding (или disposable, как здесь предложили). 

Вот, что пишут о первом: A range of documentation may be required depending on the scaffolding and scaffold. For example, prefabricated scaffolding requires plant design registration. The construction of a scaffold where a person can fall more than two metres will generally require a Safe Work Method Statement (SWMS) for construction work (https://www.safeworkaustralia.gov.au/system/files/documents/1703/scaffolds-scaffolding-work-general-guide.pdf). 

В одном из документов встретилась такая формулировка: The purpose of scaffolding construction is to provide a platform for workers and materials so that work can be carried out. Various types of scaffolding are available. These are Trestle scaffolding, Tube and clamp scaffolding, steel scaffolding, licensed scaffolding, suspended scaffolding; cantilever scaffolding, wooden and bamboo scaffolding, etc. Возможно, licensed как раз указывает на соответствии стандартам или типовым инструкциям на изготовление такого рода конструкций. Встречаются эти licensed леса не так часто, но вот еще одно подтверждение того, что это не ошибка (официальный сайт г. Вестминстер): take action to prevent protesters and other members of the public getting access to neighbouring buildings by climbing on licensed scaffolding (https://www.westminster.gov.uk/building-site-security-best-practice) . И еще одно:  Any significant alterations to a licensed scaffolding or structure that will affect the highway shall cause the licence to be withdrawn unless the highway authority first agrees such alterations (https://www.southampton.gov.uk/images/crane-licence-conditions_tcm63-377587.pdf).
