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.

Factory Ability

FAQ

 

Q: How do I choose the right prop size for my project?

A: Selection depends on:
Height requirement: Choose size with closed height < your clearance, extended height > your need
Load calculation: Total load (concrete + formwork + workers) ÷ number of props = load per prop
Safety factor: Apply 1.5–2.0 safety factor to working load limits
Foundation condition: Ensure base plates suit ground conditions
Example: For a 3.0m ceiling with 5 ton load using 4 props → 1.25 ton/prop → Select Size 2 (39.5 kN capacity at 1.9m)

Q: Why does load capacity decrease with height extension?

A: This is due to slenderness ratio (length vs. cross-section):
Longer props act more like slender columns
Increased risk of buckling under compression
Euler's buckling formula governs this relationship

Q: What surface treatment options do you offer?

A: Multiple finishes for different environments:
