Threaded adjustable steel prop is a common telescopic temporary shoring equipment for construction. Made of Q235B/Q345B steel with painted or galvanized surface. It adopts Acme thread for precise height adjustment, featuring strong load-bearing capacity, stable structure and easy operation. Widely used for concrete formwork support, beam and slab shoring, building renovation and temporary structural support projects.
Threaded adjustable steel prop, also known as acrow prop or telescopic steel support, is a classic and essential temporary shoring component in modern construction industry. It is mainly composed of outer tube, inner tube, threaded nut, safety pin, top plate and base plate. The unique Acme threaded structure enables stepless and precise height adjustment, which can perfectly adapt to different floor heights and construction requirements on site. Compared with traditional wooden supports, this steel prop has higher bearing capacity, better structural stability and longer service life, and it can be reused for hundreds of cycles, greatly cutting comprehensive construction costs.
Our threaded adjustable steel props are mainly manufactured from high-quality Q235B carbon steel, and Q345B high-strength steel is optional for heavy-load working conditions. The outer and inner tubes are made of seamless or high-frequency welded steel pipes with uniform wall thickness and excellent compression resistance. All welding positions between tubes and end plates are fully welded with smooth weld seams, no cracks or deformation. The standard tube outer diameters include 48mm, 56mm and 60mm, with wall thickness ranging from 1.6mm to 3.5mm to meet light-duty, medium-duty and heavy-duty load demands. The top and base plates adopt square or round steel plates with sufficient thickness, expanding the contact area to prevent sliding and sinking on construction ground.
For surface treatment, we provide multiple options including anti-rust painting, pre-galvanizing and hot-dip galvanizing. Painted finish is cost-effective for short-term projects, while galvanized treatment delivers outstanding anti-rust and anti-corrosion performance, suitable for long-term repeated use and humid outdoor environments. The threaded part is processed with fine machining, ensuring flexible rotation, smooth adjustment and good wear resistance after long-time use. Equipped with safety pin design, it can lock the inner tube firmly to avoid accidental retraction and enhance overall safety during construction.
The adjustable height range covers 1.6m to 6.0m, covering most indoor and outdoor construction scenarios. All products are strictly tested for load-bearing, compression resistance and mechanical performance, complying with EN 1065 and relevant domestic and international construction safety standards. This product is widely applied in concrete formwork support for floor slabs, beams and columns, temporary support during building renovation and demolition, tunnel and bridge formwork shoring, as well as various temporary load-bearing structures.
With simple structure, easy assembly and disassembly, our steel props save labor and improve working efficiency. All products adopt standard export packaging, bundled with steel straps for safe transportation over long distances. Reliable quality, reasonable price and complete specifications make our threaded adjustable steel props favored by construction contractors, formwork companies and scaffolding rental enterprises worldwide.
