| Featuring leak-proof assembly and outstanding reusability, this composite mould accelerates construction progress and improves concrete surface finish for residential, bridge and factory projects. | |||||||||
Steel-wood composite formwork represents a new generation of modular construction materials. Its main frames are integrally processed from Q235 cold-rolled steel or hot-dip galvanized steel, embedded with thickened phenolic waterproof multi-layer hardwood panels.
Combining the core strengths of two traditional formwork types, the steel frame provides sufficient rigidity and outstanding extrusion resistance & durability, while the lightweight wooden panels allow free on-site cutting, sanding and deliver superior concrete finishing effects. Panels interlock tightly to eliminate mortar seepage during pouring, with easy and labor-saving assembly & disassembly.
Applicable to all cast-in-place concrete construction scenarios including high-rise residential buildings, commercial office towers, municipal bridges, underground utility tunnels and industrial plants, it simultaneously achieves three core construction goals: quality improvement, schedule acceleration and material cost reduction, emerging as the mainstream upgraded formwork material for modern construction sites.
Steel-Wood Composite Structure, Flawless Casting Finish
Thickened steel outer frames with built-in stiffeners deliver strong overall load-bearing and lateral pressure resistance. During concrete pouring, they effectively resist expansion and deformation to eliminate form bulging, expansion and slurry leakage. Walls, beams and columns feature neat corners and qualified flat panels, drastically cutting labor costs for later sanding and repairing.
Long Reusable Lifespan to Reduce Project Material Expenses
The wear-resistant, washable panel surface and drop & impact-resistant steel frames deliver an overall service life 3–5 times longer than ordinary wooden formwork. For long-term large-scale civil construction projects, it reduces frequent procurement of new formwork and lowers total project material expenditure.
Lightweight Design to Fully Improve Team Construction Efficiency
Over 40% lighter than all-steel formwork, it allows single workers to complete transportation, assembly, on-site drilling and cutting. Low operation thresholds for form erection and stripping shorten construction cycles of single buildings and save massive man-hours.
All-Weather Weather-Resistant Material for Open-Air Harsh Construction Sites
Panels adopt high-temperature phenolic waterproof pressing technology, resisting rot, peeling and layered cracking even under long-term open-air storage or damp underground construction. Construction stability remains unaffected by rainy and snowy weather.
Fair-Faced Finish Eliminates Secondary Plastering Procedures
Polished, dense panel surfaces deliver uniform and sleek base surfaces after concrete stripping, directly meeting fair-faced wall standards without extra mortar leveling, saving both plastering material and labor costs.
Modular Universal Panels with Customization for Special Shapes
Modular standardized design compatible with most mainstream building support and reinforcement systems on the market. Factories can produce customized arc-shaped, special-shaped and cylindrical formwork to fit irregular beams, columns, foundations and culverts.
