Product Introduction 

• Purpose: The Base Jack is used for leveling and load-bearing at the bottom of the scaffolding; the U-Head Jack is installed on the top of the vertical pole to support beams/formwork. Both are key components for height fine-tuning.
• Type: Solid/Hollow, adapted to different load and installation scenarios.
• Surface Treatment: Galvanized (commonly used)/Black coating, corrosion-resistant and suitable for humid construction site environments.
• Core Components: Threaded rod, cast nut, base (for Base Jack)/U-shaped bracket (for U-Head Jack), with stable thread engagement and smooth adjustment.
• Packaging: Pallet packaging suitable for sea freight; customized packaging solutions are supported.

Yupinjia Formwork Support Struts — Customized Solutions for Full-Scenario Construction Needs

As a professional formwork support manufacturer in China, Yupinjia specializes in providing high-adaptability and high-bearing-capacity formwork support strut series products. We offer comprehensive customization services covering various construction scenarios, meeting diverse project requirements through premium craftsmanship and abundant product options.

Core Customization Services

We support precise customization based on actual construction needs, with flexible adjustments for height adjustment range, inner/outer tube dimensions, and upper/lower plate sizes and shapes. Whether for conventional beam-slab support or special-shaped component shoring, our products achieve accurate adaptation while ensuring easy installation and structural stability.

Load-Bearing Capacity Graded Selection

Divided into three series (Light-duty, Medium-duty, Heavy-duty) based on load requirements, tailored to different working conditions:

• Light-duty: Suitable for low-load, small-span scenarios such as floor slabs and small secondary beams; featuring flexible turnover and high cost-effectiveness.
• Medium-duty: Meets general load requirements for conventional beam-slabs and ordinary frame structures; the preferred choice for civil construction projects.
• Heavy-duty: Specifically designed for high-load scenarios including transfer floors, long-span beams, and thick slabs; offering strong bearing capacity and sufficient safety margin, to be used with special construction plans.

Multiple Surface Treatment Processes

Three anti-corrosion surface treatment options are available, adapting to different environmental conditions and effectively resisting rust, corrosion, weathering, and daily wear:

• Spray Coating: Economical and practical, suitable for dry construction sites and short-term turnover projects.
• Galvanizing: Standard anti-corrosion configuration, suitable for humid or open-air construction scenarios with high turnover times.
• Hot-Dip Galvanizing: High-efficiency anti-corrosion process with excellent weather resistance; ideal for coastal high-humidity environments, harsh conditions, or long-term reuse needs, ensuring longer service life.

Full-Series Product Matrix

• Steel Formwork Supports with Upper & Lower Base Plates: Stable load-bearing, suitable for large-area uniform shoring at the bottom of slabs.
• Fork-Head/U-Head Formwork Support Struts: Precisely support wooden beams and section steel, widely used for beam bottom and primary/secondary keel support.
• Push-Pull Formwork Supports: Efficient adjustment, fast erection and dismantling, improving construction efficiency.
• Adjustable Steel Supports: Flexible height fine-tuning function, easily adapting to uneven ground and elevation differences.
• Cup-Sleeved Support Struts: Accurate positioning, effectively reducing construction deviation; suitable for key node shoring.
• Groove Support Struts: Specifically designed for special-section components, meeting the support needs of irregular structures.
