Why choose our aluminum stub pins?

1. High-quality aluminum alloy material for superior performance

Made of 6061/6063 aerospace-grade aluminum alloy, it is more than 40% lighter than traditional steel pins, significantly reducing the workload for construction workers and improving formwork assembly efficiency. It also boasts excellent corrosion resistance and oxidation resistance, preventing rust in humid construction environments or during long-term storage. The service life can reach over 500 cycles, far exceeding the 200-300 cycles of ordinary steel pins, greatly reducing consumable replacement costs.

2. Precision Machining Process, Accurate Positioning + Secure Connection

Utilizing renowned CNC lathes for integrated processing, dimensional tolerances are controlled within ±0.02mm. The pins perfectly fit the pinholes in the aluminum formwork, resulting in a gap of ≤0.3mm after assembly. This effectively prevents concrete leakage and formwork deformation during concrete pouring, ensuring a smooth and even surface for the concrete components and reducing the need for subsequent repairs. The pin surface is treated with anodizing/sandblasting, enhancing surface hardness and wear resistance, ensuring smooth insertion and removal, and providing strong stability for repeated use.

3. Convenient and efficient installation significantly improves construction progress.

Thanks to the optimized structural design, no specialized or complex tools are required; construction workers can complete the plug-in installation manually. Each pin can be installed in just 3-5 seconds, representing an efficiency improvement of over 60% compared to traditional pins. When used with dedicated locking plates, it provides strong locking force and can withstand concrete lateral pressure of ≥8kN, ensuring the stability and safety of the formwork system during construction, effectively shortening the construction period and facilitating early project completion.

4. Strong Versatility + Customizable, Adapting to Diverse Needs

Standardized production eliminates the need for additional modifications to template hole sizes, reducing procurement and adaptation costs. It also supports customization of pin products with different diameters, lengths, and surface treatments based on customer aluminum formwork specifications and construction site requirements, meeting the personalized fastening needs of special projects.

5. Environmentally friendly and cost-effective, aligning with engineering trends

Aluminum alloy material is 100% recyclable, with high recycling value, making it more in line with the concept of green building construction compared to traditional steel pins. With long-term reuse, the cost of pins per square meter is reduced by 30%-50%, and combined with the savings in labor and transportation costs due to its lightweight nature, the overall economic benefits are significant.
