Adjustable steel props, also referred to as telescopic props, are a versatile type of support used in various construction applications such as formwork, shoring, and falsework 1. They are made up of an outer steel tube that is threaded and an inner steel tube that slides into the outer tube, allowing for height adjustment by rotating the outer tube 1. These props are easy to store and transport, making them suitable for fast-paced construction projects.
Steel props can be categorized based on their carrying capacity into lightweight, middle duty acrow prop, light-duty acrow formwork prop, and heavy-duty acrow prop 2. The surface treatment of steel props can vary, including spray-painted, galvanized, and hot-dip galvanized, which helps prevent rusting, corrosion, and general wear 2. The height of adjustable steel props can be adjusted telescopically to achieve the required height, and they typically consist of a top plate, bottom plate, inner tube, outer tube, sleeve, nut, and pin, allowing for easy adjustment and reuse
Adjustable steel prop is frequently used in formwork and construction to support the floors, ceilings, bridges and beams. With its high load-bearing capacity, it is popular on temporary supports during building repair or alteration work. The advantages are easy to use and time-effective to install, also lower cost. In construction, steel props is used as vertical support in scaffolding as below situation, such as: removing walls, making holes, temporary support for ceiling, beams and so on.
