Adjustable Steel Support

Adjustable Steel Support, a versatile vertical load-bearing component in construction, enables telescopic height adjustment (typically 1.5m-4.5m) to fit diverse project needs. It’s widely used for formwork support, scaffold reinforcement, and structural bracing, ensuring stable vertical load transfer during concrete pouring or equipment installation.

Structurally, it has a two-section telescopic design: an outer thick-walled steel tube (Q235/Q355, Φ60-Φ89mm) as the main load carrier, and an inner tube (Φ48-Φ76mm) with a top plate (100×100mm, ≥6mm thick) for bearing loads. A locking mechanism (spring pin/bolt) fixes the adjusted height; heavy-duty models add a locknut for safety. A base plate (≥150mm, ≥5mm thick) prevents ground sinking.

Classified by load: Standard (≤20kN), medium-duty (20-35kN), heavy-duty (≥35kN). By height: Short (1.5-2.5m), medium (2.5-3.5m), long (3.5-4.5m).

Key applications include formwork support for beams/slabs, temporary bracing for prefabricated components, and scaffold reinforcement.

Safety rules: Match load requirements; secure the lock after adjustment; install on solid ground with pads; avoid eccentric loads; inspect for cracks/bends before use—discard damaged units.
