| Steel Frame Wood Formwork adopts robust cold-rolled steel frames matched with waterproof multilayer plywood, merging high structural stability and flexible cutting performance for cast-in-place concrete construction. | |||||||||
Steel-frame wood formwork is a modular steel-wood composite formwork system tailored for modern concrete construction. Its integral frames are precision fabricated from high-strength cold-rolled steel and galvanized steel, while the panel surfaces are laminated with multi-layer waterproof hardwood plywood.
This product integrates the core merits of two conventional formwork types: the steel frame delivers exceptional rigidity, high load-bearing capacity and anti-deformation performance, whereas the wooden panel retains light weight, easy on-site processing and superior concrete finishing texture.
Boasting high splicing precision, tight sealing and outstanding wear resistance for repeated use, its simple assembly and disassembly procedures fully resolve two long-standing industry pain points: pure wooden formwork’s tendency to deform and short service life, and all-steel formwork’s excessive dead weight and inconvenient cutting. Widely applicable to cast-in-place concrete projects including building construction, municipal bridges, underground utility tunnels, factory infrastructure and water conservancy renovation, it is a new preferred construction material for construction sites to boost quality, accelerate progress and cut material & labor costs.
High Rigidity & Anti-Deformation, Zero Defects After Pouring
Constructed with thickened integrally stamped steel borders, the system features robust structural rigidity and stable load-bearing performance. It effectively resists lateral pressure during high-pressure concrete pouring, eliminating common construction defects such as formwork expansion, bulging, mortar leakage and slurry seepage. Walls and columns achieve high compliance rates of flatness and verticality, drastically reducing labor and material expenses for subsequent sanding, repairing and leveling.
Wear-Resistant & Reusable with Outstanding Comprehensive Cost Performance
Breaking the limitation of single or limited reuse cycles of traditional wooden formwork, the steel frame resists impact, abrasion and extrusion, suffering minimal damage during on-site transportation, stacking and pouring. It enables far more turnover cycles than ordinary wooden formwork. For long-term large-scale construction projects, it significantly cuts frequent formwork procurement frequency, lowers total project material investment and delivers a short payback period.
Waterproof & Anti-Corrosion, Adaptable to Harsh Site Conditions
The panels are hot-pressed waterproof plywood bonded with phenolic resin, offering excellent moisture-proof, anti-corrosion and anti-cracking properties. It withstands open-air storage, rainy humid weather and damp underground construction environments, resisting peeling, debonding, rotting and deformation for long-term service. Its superior weatherability suits all-year outdoor and underground construction scenarios.
Lightweight Construction to Greatly Shorten Construction Schedules
Its scientifically calibrated dead weight enables manual handling without heavy lifting equipment. Workers can easily transport and rapidly assemble panels, which support arbitrary on-site cutting, drilling and resizing. Panels interlock tightly with precise alignment, simplifying form erection and stripping processes with high construction fault tolerance. It substantially improves team work efficiency and shortens the overall project timeline.
Fair-Faced Concrete Finish, Eliminating Secondary Plastering
Panels undergo precise smoothing treatment with dense, smooth surfaces free of pits and bumps. After concrete pouring and stripping, the uniform and sleek surface directly meets fair-faced concrete standards, removing the need for secondary plastering and leveling. It streamlines construction procedures, saves mortar and labor costs, and elevates the overall aesthetic quality of projects.
Wide Compatibility & Support for Customization
A complete range of standard sizes ensures universal compatibility with all mainstream building support systems on the market. Custom non-standard and special-shaped panels are also available to flexibly accommodate diverse construction scenarios, including shear walls, load-bearing columns, beam-slab structures, equipment foundation piers, municipal culverts and irregular underground utility tunnels. It delivers maximum universality and adaptability.
•Standard Sizes: Mainstream universal sizes such as 1220×2440mm and 1000×2000mm; custom non-standard and special-shaped dimensions available per construction drawings
• Frame Material: Premium cold-rolled steel plate / hot-dip galvanized steel frame, integrally stamped for rust resistance, impact resistance and structural stability
• Panel Material: Multi-layer waterproof hardwood plywood, high-pressure bonded with phenolic waterproof adhesive for stable waterproof & moisture-proof performance
• Craft Structure: Integrally stamped structure with thickened reinforced borders; panel corners are strengthened against cracking and collision for enhanced structural strength
• Applicable Scenarios: Shear walls, building columns, beam-slab floors, equipment foundations, municipal culverts, underground utility tunnels, cast-in-place water conservancy structures, etc.
Widely adopted in all cast-in-place concrete construction projects including residential communities, high-end office buildings, industrial plants, underground civil air defense garages, municipal bridges, urban pipeline renovation, medium & small water conservancy projects, urban village renewal, and cast-in-place auxiliary structures for prefabricated buildings. It fits civil, industrial and municipal engineering works universally.
