Comparison of Pull-out System and Screw System: Analyzing New Construction Advantages from Three Dimensions
In the wave of industrialized building upgrades, aluminum alloy formwork has become a core material for building construction. The technological competition between the two core systems of aluminum formwork-the tie-plate system and the traditional screw system-has long been a focus of industry attention. As a professional enterprise deeply rooted in the aluminum formwork field, we leverage our core technologies to dissect the absolute technological advantages of the tie-plate system from three core dimensions: construction quality, installation efficiency, and overall cost. We use data and processes to demonstrate the construction strength of the new generation of aluminum formwork systems!

I. Quality Upgrade: The Tie-plate System Solidifies the Bottom Line of Engineering Quality. Construction quality is the core foundation of a building. From process design to material selection, the tie-plate system is superior to the screw system in every aspect, avoiding common quality problems from the source!
01. Precise and Uniform Wall Thickness: The tie-plates are fixed-length high-strength manganese steel components, securely connected to the aluminum formwork edge ribs via pins and milled grooves. The length is fixed and without deviation, completely avoiding the uneven wall thickness problem caused by inconsistent nut tightening in the screw system. The vertical and horizontal accuracy of the wall surface is greatly improved, easily achieving the "50% vertical, 50% horizontal, 50% high" standard.

02. Self-Waterproofing with Zero Hidden Dangers: Using tie rods eliminates the need for drilling holes in the formwork panel. After demolding, only the protruding tie rod head needs to be broken (the break is concealed within the wall surface by 5mm), leaving no bolt holes on the exterior wall. This ensures the integrity of the concrete wall and eliminates seepage and cracking problems caused by improper sealing of bolt holes, completely saving you the trouble of later waterproofing repairs.

03. Superior Load-Bearing Capacity and Stable Construction: The tie rods are made of 50Mn high-strength manganese steel, and each batch undergoes rigorous tensile testing. A single rod can withstand a tensile force of over 28kN. Under the lateral pressure of 80kN/㎡ concrete, the stress is still far below the design value. The scientifically arranged denser bottom and sparser top layout effectively prevents formwork bulging and bursting, ensuring stable construction quality for both 3.0m standard floor height residential projects and 4.9m super-high floor height projects.

II. Efficiency Improvement – The Pull-in System Restructures Construction Rhythm: Construction efficiency determines project cycle time. The pull-in system, with its lightweight and modular design, significantly reduces labor intensity, accelerating the entire installation and dismantling process! 01 Lightweight Construction Reduces Burden by 60%: The pull-in system requires only two horizontal single-pipe square tubes for interior walls, with a single project's steel pipe weight being only about 5 tons. Compared to the bulky configuration of the screw system with four horizontal double-pipe back ribs and vertical back ribs, steel usage is reduced by 60%, making formwork handling, installation, and transfer easier, significantly improving labor efficiency. 02 Quick Installation and Dismantling with No Cumbersome Procedures: The pull-in system, paired with a dedicated square tube clamp, allows for easy clamping of the square tube with a hammer, eliminating the significant idle stroke required for nut tightening in the screw system. No need for subsequent verification of nut tightening, simplifying the installation process. Dismantling only requires removing the aluminum formwork, eliminating the cumbersome steps of screw dismantling, thus accelerating the overall construction pace. 03. Standardized Assembly and Strong Adaptability: The tie-plate system is highly compatible with the "Lego-like" assembly concept of aluminum formwork. The standardized process of milling groove positioning and pin connection eliminates the need for on-site secondary processing. It can be quickly adapted to both standard residential and high-rise commercial projects, significantly shortening the construction cycle.
III. Cost Optimization – The Tie-plate System Achieves Comprehensive Cost Reduction. Good technology should not only be high-quality and efficient but also create real value for the project. The tie-plate system achieves the optimal comprehensive cost solution in terms of material consumption, labor costs, and post-construction maintenance. Data speaks volumes!
01. Significantly Reduced Steel Consumption: Taking a 2000㎡ formwork area project as an example, the total weight of steel components in the tie-plate system is 35% lower than that of the screw system. The consumption of core components such as back ribs, screws, and round washers is significantly reduced, resulting in a substantial decrease in material procurement costs.
02. Lower Cost per Square Meter and Greater Convenience: The cost per square meter for the screw system due to screw hole sealing is far higher than that of the tie-plate system. The tie-plate system completely eliminates the labor costs of sealing wall holes, avoiding secondary repair costs due to substandard sealing.

03. Zero-Cost Operation and Maintenance Throughout the Entire Lifecycle: The tie-plate system eliminates the need for bolt holes, fundamentally preventing wall seepage, cracking, and other post-construction maintenance issues caused by holes. This saves on post-project delivery repair costs, ensures the collection of warranty deposits, and reduces maintenance hassles for homeowners, achieving cost reduction for both developers and homeowners. With the continuous iteration and development of the Tianqu aluminum formwork tie-plate system, it will gradually become the mainstream in the future. It is not simply a technological upgrade, but a new construction system adapted to the industrialization and green development of building industry, based on the characteristics of aluminum alloy formwork materials. Compared to the bolt system, the tie-plate system perfectly solves the common quality problems, efficiency bottlenecks, and cost pain points of traditional aluminum formwork construction, achieving the triple goals of better quality, higher efficiency, and lower cost. From its widespread application in various residential projects to its successful breakthroughs in complex scenarios such as high-rise buildings and basements, the technical strength of the tie-plate system has been fully validated by the market. As a veteran in the aluminum formwork industry, we always focus on technological innovation and are committed to creating highly adaptable and cost-effective aluminum formwork products with a pull-tab system, empowering construction projects and driving the industry towards a more efficient, greener, and higher-quality direction!
