Characteristic
1. Premium high-strength steel is used as the raw material for Acrow props, which gives our products a strong load-bearing capacity than other goods.
2. Accuracy without burrs is provided by automated precision drilling and cutting (with ±1mm tolerance).
3. To guarantee product quality, load testing and quality inspection is on all acrow props before loading.
4. Processing by high precise rolling threading and high-strength welding under standard.
5. Rusting prevention with hot-dip galvanized surface or electro-galvanizing , which achieve longer service life.
Application
Whether you are a building materials distributor or a construction contractor, we provide customized solutions tailored to your project requirements. This includes, but is not limited to, a wide range of specifications and dimensions, along with engineering support and installation services.
Concrete Pouring and Formwork Support
When pouring fresh concrete for slabs, roofs, or floors, acrow props are used to support formwork structures until the concrete achieves sufficient strength. This prevents structural sagging, deformation, or cracking, ensuring construction quality and structural stability.
House Renovation and Structural Alterations
When demolishing walls, creating door/window openings, or modifying load-bearing structures. Steel acrow props can be installed to share loads and maintain the stability of load-bearing walls and ceilings.
Installation of Load-Bearing Beams and Lintels
During the installation of beams, lintels, or joists, acrow props provide temporary support. They effectively bridge structural gaps, preventing displacement or collapse to ensure construction safety.
Demolition and Renovation Projects
In building demolition or large-scale renovation projects, when portions of the structure must remain intact. Acrow props help stabilize the remaining structure, reducing construction risks and preventing accidental collapse.
Wall Reinforcement
During construction or renovation, steel acrow props provide temporary reinforcement for walls or localized structures, enhancing construction safety.
Scaffolding and Auxiliary Construction Systems
Mini acrow props serve as components within scaffolding systems, supporting work platforms or auxiliary structures to increase construction flexibility.

FAQ
Q: How do you adjust the height of a steel prop?
A: Two-stage adjustment:
Coarse adjustment: Pull inner tube to approximate height, align pin holes, insert prop pin
Fine adjustment: Rotate threaded collar/nut for precise leveling (±50mm typically)
Time-saving tip: Our forged steel adjusting ring nuts with optimized thread pitch allow quick release and adjustment.
Q: Can one person erect steel props?
A: Yes, one person can handle steel props due to their lightweight design (10–30kg per prop). However:
Heavy-duty props (Size 3–4) may require two people for safety
High installations should follow OSHA/EN safety protocols
Always use proper lifting techniques
Q: What base and head options are available?
A: Base plates:
Standard square base: 120×120×4mm (most common)
Flower/shaped base: Better grip on uneven surfaces
Adjustable base jack: For fine leveling on slopes
Top plates:
Flat plate: 120×120×4mm for beams
U-head: 4"/6"/8" width for timber beams
Adjustable U-head: Tilts to accommodate angled beams
Fork head: For multiple beam support
Q: How do I ensure stability on uneven ground?
A: Best practices:
Use mud sills (50×250mm timber planks) under base plates
Base jacks for slopes up to certain gradients
Outriggers or tripod supports for very uneven terrain
Never use props on frozen, soft, or unstable ground without proper foundation
