Advantages

1. Strong Customization Capability – Exactly as Your Drawing
We have extensive experience producing a wide range of Base Jack types, including solid, hollow, and swivel base jacks. Based on customer drawings, we can achieve nearly 100% visual and structural consistency, earning consistent high praise from buyers worldwide.

2. Flexible Surface Treatment Options
Choose from painted, electro-galvanized, hot-dipped galvanized, or black finish. No welding required if you prefer – we can produce screw and nut components separately to suit your assembly needs.

3. Application-Based Division – Upper Jack & Base Jack
Our screw jacks are clearly categorized by usage:

U-head jack (upper jack) for top-side support

Base Jack for bottom adjustment and load distribution
This ensures the right product for the right position in any scaffolding system.

4. Material-Based Types for Different Load & Cost Needs

Hollow screw jack – made from steel pipe, lighter weight, cost-effective

Solid screw jack – made from round steel bar, higher strength and durability

5. Mobility Option – Screw Jack with Caster Wheel
Designed for movable or mobile scaffolding systems.

Hot-dipped galvanized finish for corrosion resistance

Installed at the base to enable easy movement during construction

Ideal for projects requiring frequent repositioning

6. Common Screw Jack – Enhances Structural Stability
Used in engineering construction as fixed supports, significantly improving the overall stability and safety of the entire scaffolding system.

FAQS

Q 1：What is the difference between Base Jack and U-head jack?
A:Base Jack is installed at the bottom of scaffolding legs for leveling and load distribution, while U-head jack (also called upper jack) is used on top to support beams or formwork. Both are essential screw jack types.

Q 2：What types of Base Jack can you manufacture?
A:We produce various Base Jack types including solid base jack (made from round steel bar), hollow base jack (made from steel pipe), swivel base jack, and base jack with caster wheels for mobile scaffolding. Custom designs based on drawings are also available.

Q 3：What surface treatments are available for screw jacks?
A:Surface treatment options include painted, electro-galvanized, hot-dipped galvanized (HDG), or black finish. For base jacks with caster wheels, HDG is commonly used for better durability and corrosion resistance.

Q 4：Can you produce screw jacks without welding?
A:Yes. We can manufacture the screw part and nut part separately according to your requirements. Even if you do not need welding assembly, we can still provide un-welded screw jack components.

Q 5：What is the purpose of screw jack with caster wheel?
A:The screw jack with caster wheel is typically hot-dipped galvanized and used in mobile scaffolding systems. It allows easy movement of scaffolds on construction sites while still providing height adjustment and stability. Common screw jacks (without wheels) are used for fixed engineering scaffolding to enhance overall system stability.
