Adjustable Steel Prop & Acro Jack (Direct China Manufacturer)

Welcome to a leading Steel Prop and Acro Jack manufacturer in China. Based in Tianjin—the heart of China’s steel industry—we specialize in the mass production of premium adjustable shoring props for global construction markets. Known regionally as Acro Jacks, shore posts, or scaffolding props, these robust load-bearing tools are essential for securing concrete formwork, temporary beams, and reshoring structures.

By sourcing directly from our factory, international contractors and scaffolding rental enterprises eliminate middleman margins while guaranteeing consistent product quality. Whether you require light-duty props for residential renovations or heavy-duty Acro Jacks for major infrastructure, our ISO-certified facility provides comprehensive OEM customization, utilizing high-grade Q235/Q345 steel and advanced anti-corrosion treatments (Galvanized, Powder Coated, or Painted).

Key Advantages

Direct Factory Cost Efficiency: Cut out trading company markups. Sourcing directly from our Tianjin factory ensures the most competitive wholesale pricing for your scaffolding and formwork procurement.
Strict Load-Bearing Quality Control: Our Acro Jacks undergo rigorous vertical load testing. The threaded sleeves are precision-lathed, and structural welds are flawlessly executed without air holes, ensuring zero buckling under intense concrete slab weights.
Massive Production Capacity: Equipped with automated cutting, welding, and coating lines, we maintain a vast monthly output. This guarantees stable, on-time deliveries for urgent, large-scale international engineering projects.
Comprehensive Customization (OEM): We understand that different markets have different regulations (e.g., BS4074 in the UK). We customize tube diameters, wall thicknesses, plate designs (U-head, flower, flat), and locking pins to perfectly match your local standards and branding colors.

Product Applications

Concrete Slab Shoring: Providing exact, adjustable vertical support under timber or steel beams during the pouring and curing of concrete slabs.
High-Rise Reshoring: Temporarily distributing structural loads in multi-story buildings during consecutive concrete pours.

Wall & Column Bracing: Utilized horizontally or diagonally (with specific attachments) to hold formwork securely in place.
Temporary Structural Support: Essential for structural alterations, building repairs, and trench strutting.

Packaging & Delivery

Optimized Container Loading: Steel props are extremely heavy. Our logistics experts skillfully bundle the Acro Jacks (typically 50 pcs/bundle) with steel strips and load them into 20ft containers, ensuring you hit the maximum payload without exceeding port weight restrictions.
Palletized for Easy Handling: To facilitate rapid unloading at your warehouse or job site, bundles can be securely mounted on wooden or steel pallets.
Strategic Factory Location: Located mere kilometers from Xingang Port (Tianjin), our supply chain is immune to severe inland transport delays, ensuring rapid vessel boarding and swift global transit.

Frequently Asked Questions (FAQ)

Q: What is the difference between a Steel Prop and an Acro Jack?
A: There is no functional difference. “Acro Jack” (or Acrow Prop) is simply the traditional term widely used in the UK, Australia, and European markets, while “Steel Prop” or “Shoring Prop” is more universally used. They both refer to the same adjustable vertical support equipment.

A: Yes. As a direct manufacturer, we frequently customize the tube diameters (e.g., 48mm inner / 60mm outer) and material thicknesses (up to 3.0mm+) to fully comply with BS4074 and other demanding regional load-bearing safety standards.

A: To provide the best direct-factory pricing, our standard MOQ is one full 20ft container (approximately 1,500 to 2,500 pieces, depending on the prop’s weight and length).

A: Absolutely. We offer professional powder coating and painting services. You can specify the exact RAL color code and even have your company logo stamped or stickered on the props.
