【Product Overview】
The Adjustable Steel Prop (also known as telescopic steel post or acrow prop) is a critical vertical support element in concrete formwork systems. Designed with an inner and outer steel tube combined with a pin or threaded adjustment mechanism, it provides reliable load-bearing capacity for slab formwork, beam formwork, and temporary shoring applications in residential, commercial, and infrastructure projects.
Compared to fixed-length timber props, adjustable steel props offer greater flexibility, higher load capacity, and longer service life, making them the preferred choice for modern construction sites.
【Why Choose Adjustable Steel Prop?】
Height Adjustable (1.5m – 4.5m+ range)– Fits various floor-to-ceiling heights with simple pin or screw adjustment.
High Load Capacity (15–25 kN per prop)– Safely supports concrete slabs and beams during curing.
Durable Steel Construction (Q235/Q355)– Galvanized or painted finish prevents rust.
Easy & Fast Installation– No cutting or customizing required on-site.
Stackable for Storage– Saves warehouse and transport space.
Long Service Life– Reusable across hundreds of construction cycles.
【Key Applications – Real Estate & Construction】
Slab and beam formwork support
Temporary shoring for under-construction floors
Bridge and tunnel falsework
Foundation and retaining wall bracing
Scaffolding and event structure support
