Precision Shoring & Micro-Height Adjustment

Malmo Steels manufactures a complete range of formwork props and screw jacks designed for temporary vertical support during concrete slab casting, beam staging, falsework and wall shutter bracing. Every prop features rolled high-tensile threads, welded footplates and captive G-pins for reliable on-site height setting.

Manufactured under strict ISO-grade quality controls, our props and base jacks are available in standard lengths from 2.0 m up to 4.5 m with custom lengths available on request.

Engineering Advantages

  • High Load Capacity — High yield prime ERW steel tubes with reinforced bases.
  • Self-Cleaning Threads — Continuous rolled thread resists concrete slurry adhesion.
  • Versatile Head Options — U-heads, slotted forkheads, flat base plates and swivel bases.
  • Anti-Corrosion Longevity — Hot-dip galvanizing, electro zinc plating or electrostatically painted.
