Adjustable Steel Prop vs Shoring Prop: Key Differences | TSX Groupe
TSX Groupe manufactures both adjustable steel props and shoring props for formwork support and temporary works. In many projects the two terms describe the same product family, but “shoring” also covers a wider range of temporary support systems. This guide explains the differences between them, their typical applications, and how to choose the right solution for your project.
What Is an Adjustable Steel Prop?
An adjustable steel prop is a two-piece telescopic column made of an inner and an outer steel tube with a pinned adjustment mechanism. It supports formwork, slabs, beams and walls during concrete pouring and curing, and can be extended or shortened quickly on site. Our standard range covers working heights from 1.6 m to 6.0 m, with 48 mm inner and 60 mm outer tubes in Q235 or Q355 steel. See our steel prop manufacturer & supplier page for full specifications and surface treatment options.
What Is a Shoring Prop?
“Shoring” is the general term for temporary support structures that hold a building or other structure in place until it becomes self-supporting. A shoring prop is the vertical load-bearing column used inside such a system, often combined with timber or steel walers, fork heads, base plates and bracing. In many markets the term “shoring prop” is used interchangeably with “adjustable steel prop” or “acrow prop”. However, heavy-duty shoring can also mean engineered frame systems such as ringlock or cuplock shoring towers, which are used for very heavy or tall loads.
Adjustable Steel Prop vs Shoring System at a Glance
| Aspect | Adjustable Steel Prop | Shoring System / Shoring Frame |
|---|---|---|
| Structure | Two telescopic tubes with pin adjustment | Engineered frames (e.g. ringlock, cuplock) assembled into towers |
| Typical load range | Light to medium vertical loads | Heavy vertical loads, large spans, tall heights |
| Typical applications | Slab, beam, wall and column formwork support | Transfer floors, deep basements, bridge decks, heavy slab soffits |
| Setup speed | Very fast, one person can adjust height | Requires assembly of multiple frames and bracing |
| Flexibility | Highly flexible for irregular layouts | Systematic grid, best for repeated large areas |
| Cost | Low unit cost, economical for small areas | Higher investment, economical for large repetitive areas |
Note that a shoring prop used as a single column performs the same function as an adjustable steel prop; the comparison above focuses on shoring frames and systems, which are the heavy-duty alternative.
How to Choose: Steel Prop or Shoring System?
- Slab and beam formwork on normal floors: adjustable steel props are usually the most economical and fastest option.
- Heavy or tall loads (transfer floors, deep basements): consider engineered shoring frames or ask our engineers to check the loading.
- Large repetitive areas: shoring systems combined with flying forms can reduce labour cost per square metre.
- Renovation and localised support: steel props with base plates and fork heads are simple to position in tight spaces.

Steel Prop vs Shoring FAQ
Is a shoring prop the same as an adjustable steel prop?
In most cases yes: both refer to a single telescopic steel column used for temporary vertical support. “Shoring” additionally covers engineered frame systems used for heavier loads.
Can steel props be used for heavy shoring?
Steel props are designed for light to medium loads. For heavy loads, tall heights or large spans, engineered shoring frames, or a combination of props with walers and bracing, is normally required. Contact our engineers with your load data for a recommendation.
What is the load capacity of an adjustable steel prop?
Load capacity depends on extended height, tube thickness and material grade. Provide your working height and required load, and our engineers will specify the correct prop size and thickness for your project.
When should I use frame shoring instead of steel props?
Use frame shoring for very heavy loads, high floor-to-floor heights, or large repetitive areas where the investment pays back through reuse. For ordinary slab and beam formwork support, adjustable steel props are usually more economical.
