Reusable Steel Formwork - Long-Term Cost Optimization Solution for High-Frequency Turnover Scenarios

Reusable Steel Formwork with "ultimate reusability" as the core R&D concept, its core advantages focus on "300+ cycles of ultra-long service life, 0.2 CNY/㎡ cost per use, and 90% residual value rate", specially designed for formwork leasing companies and large-scale infrastructure projects.

1.1 Military-Grade Material, Service Life Exceeding Industry Limits

Made of 2.5-3mm thick Q355 low-alloy high-strength steel (yield strength ≥345MPa), through "600℃ high-temperature aging treatment + low-temperature tempering" process, the steel fatigue life is increased by 50%, which can withstand 300 assembly-disassembly impacts without plastic deformation. Equipped with "double angle steel keel + full welding reinforcement" structure, the lateral pressure resistance reaches 90kN/㎡, and there is no mold expansion risk when pouring high-grade concrete. The surface adopts "hot-dip galvanizing (zinc layer ≥80μm) + epoxy zinc-rich primer + topcoat" triple anti-corrosion, passing 720-hour salt spray test without rust, and maintaining 85% of original performance after 3 years of outdoor storage, far exceeding the industry standard of 200 reuses.

1.2 Total Life-Cycle Cost Optimization, Cost per Use as Low as 0.2 CNY/㎡

Calculated by "300 reuses + 90% residual value rate": Taking the standard model purchase price of 180 CNY/㎡ as an example, cost per use = (180 CNY - 180 CNY × 90%) ÷ 300 cycles = 0.06 CNY/㎡. Adding maintenance cost (0.14 CNY/㎡), the total cost is only 0.2 CNY/㎡, 75% lower than ordinary steel formwork (0.8 CNY/㎡) and 93% lower than wooden formwork (3 CNY/㎡). Equipped with "wear warning mark", the panel automatically changes color when the thickness is worn to 2mm, reminding maintenance to avoid premature scrapping and extend asset life.

1.3 Adapted to Leasing Scenarios, Maintenance Cost Reduced by 60%

Adopting "standardized panel + universal connector" design, 9 standard sizes (300×600mm-3000×1600mm) can be used across projects, reducing idle inventory. The panel edge is treated with "rounded chamfer + wear-resistant coating", no collision damage during assembly-disassembly. Maintenance only requires "water gun cleaning + local paint touch-up", with a single person maintaining 500㎡ per day, saving 60% maintenance man-hours compared to ordinary steel formwork. Supporting "refurbishment and recycling", after 300 uses, it can restore performance through "edge cutting + re-galvanizing", with a residual value rate of 90%, significantly improving the asset preservation of leasing companies.

3.1 Life Core: Fatigue Resistance Structure

The keel adopts "∠63×63×5mm equal-angle steel + diagonal brace" combination to reduce stress concentration, reducing steel fatigue damage rate by 40%; the connection between panel and keel adopts "full welding + spot welding reinforcement", with weld shear strength of 15kN, avoiding weld falling off after 300 assembly-disassembly cycles.

3.2 Cost Core: Residual Value Optimization Design

The panel reserves "20mm refurbishment allowance" and can continue to be used after edge cutting when worn; the connector is made of 304 stainless steel, no rust after 300 uses, and can be 100% recycled and reused, further improving asset residual value.

3.3 Maintenance Core: Easy Maintenance Details

The panel surface is sprayed with "self-cleaning coating", making concrete residues easy to clean without strong acid and alkali treatment; the corner is equipped with "replaceable wear-resistant block", only need to replace accessories after wear, no need to scrap the entire panel, reducing maintenance cost by 50%.

4.1 Quick Assembly Steps

 Select corresponding panels according to component size, splice horizontally via buckles;

 Install longitudinal keels and diagonal braces for reinforcement, fix with special connectors at corners;

 Check joint gap (≤0.5mm), paste sealing strips to prevent grout leakage;

 Demould 24 hours after pouring, and quickly disassemble by tapping the buckles.

4.2 Service Life Extension Tips

 Clean residual concrete with high-pressure water gun immediately after demoulding, store after drying;

 Repair rust paint in time when coating damage is found to avoid rust spread;

 Place 15cm above the ground during long-term storage, cover with waterproof cloth to prevent moisture.
