In the construction of cast-in-place concrete structures such as high-rise residential buildings, public buildings, and underground projects, interior wall formwork, as a core tooling system determining the flatness, verticality, and surface appearance of the walls, directly impacts construction speed, labor costs, and the final building quality. High-strength alloy steel interior wall formwork—made from high-quality low-alloy high-strength steel through precision cold bending, welding, and surface treatment—is gradually replacing traditional wooden formwork, bamboo plywood, and ordinary steel formwork, becoming a key support in green building and industrialized construction systems due to its excellent structural rigidity, reusability, dimensional stability, and safety reliability.
The core advantages of high-strength alloy steel interior wall formwork are primarily reflected in its superior mechanical properties and durability. Utilizing alloy structural steel with a yield strength ≥355MPa (such as Q355B or higher grade), the panel thickness is typically 2.5–4.0mm. Combined with reinforcing ribs and frames, it forms an integrated load-bearing system with high bending stiffness and minimal deformation under concrete lateral pressure. This ensures that the flatness deviation of the wall after completion is ≤2mm/2m, and the verticality error is controlled within ±3mm, significantly reducing the need for subsequent plastering and leveling. The surface is treated with hot-dip galvanizing or electrophoretic coating, providing a corrosion resistance lifespan of over 500 cycles, maintaining structural integrity even in damp basements or coastal high-salt-fog environments.
Standardized and modular design significantly improves construction efficiency. The formwork system uses uniform modules (such as 300×1500mm, 600×2400mm, etc.), allowing for rapid assembly via U-shaped clips, hook bolts, or specialized connectors, eliminating the need for on-site cutting or complex supports. Standard components are available for irregularly shaped parts such as corners, openings, and variable cross-sections, achieving efficient "building block" assembly. The entire system can work in conjunction with early stripping systems, climbing scaffolds, or aluminum formwork, shortening the standard floor construction cycle to 4-5 days per floor and reducing labor input by more than 30%. It is particularly suitable for large-scale standardized projects such as affordable housing, schools, and hospitals.
Safety and environmental advantages are equally prominent. While the alloy steel formwork is heavier than aluminum formwork, it is significantly lighter than traditional combined steel formwork, keeping the weight of a single piece within a reasonable handling range. The absence of wood eliminates fire hazards; the smooth and dense surface achieves a fair-faced concrete finish after demolding, saving approximately 15-20mm of mortar plaster, reducing building load and carbon emissions. Waste formwork is 100% recyclable, meeting national green construction evaluation standards.
Excellent economic efficiency throughout its entire life cycle. Although the initial investment is higher than wooden formwork, its 500-800 reuse cycles reduce the cost per use to only 1/3-1/2 of that of wooden formwork; maintenance-free operation, low loss, and low repair rate further reduce management costs. Combined with BIM-based detailed design, precise pre-assembly and zero-waste material handling can be achieved, improving resource utilization efficiency. Ultimately, the value of high-strength alloy steel interior wall formwork lies not only in "supporting concrete," but also in its industrial-grade precision and repeatable reliability, driving the transformation of construction from "extensive manual labor" to "refined assembly." When a wall meets delivery standards in a single pour, and when construction dust and waste are significantly reduced, this formwork system is silently reshaping the construction logic. In today's construction industry, moving towards high quality, low carbon emissions, and intelligent systems, high-performance alloy steel interior wall formwork, with its steel body, continues to solidify the quality foundation of modern architecture.
