Large Panel Formwork: The Complete Guide to Price, Specs Seamless Concrete Construction
Large Panel Formwork is one of the most advanced concrete formwork systems for the seamless casting of walls, columns, and slabs in large-scale construction projects. With its large, integrated steel panels, this wall formwork system lets you pour an entire wall in a single stage, dramatically increasing construction speed, concrete surface quality, and overall project economy. With over two decades of experience, Alborz Ghaleb manufactures and supplies large panel formwork with technical consultation, weight calculation, and up-to-date pricing.
What is Large Panel Formwork?
Definition of Large Panel Formwork
Large panel formwork is an advanced metal or composite-based formwork system designed for the seamless concrete casting of walls, columns, and occasionally slabs in large-scale construction projects. Its large, integrated panels enable rapid construction by allowing entire walls or significant structural sections to be cast in a single pour, unlike traditional modular formwork that requires piecewise assembly. The system offers high flexibility, enabling pre-designed openings for doors, windows, and utilities, making it ideal for diverse architectural plans. For an economical alternative, see our modular concrete formwork page.
History and Evolution
Originating in Europe for mass housing projects, large panel formwork has evolved to meet the demands of faster, more cost-effective construction. In recent decades, its adoption in Iran has surged, driven by companies like Alborz Ghaleb, which provide high-quality solutions tailored to modern construction needs.
Why Large Panel Formwork is the Heart of Modern Construction
Large panel formwork is a game-changer in the construction industry, delivering seamless structures, faster project timelines, and reduced costs. From high-rise buildings to bridges and dams, this system empowers engineers and contractors to achieve superior quality and durability.
Choosing the right formwork can make the difference between project success and failure. With over 20 years of expertise, Alborz Ghaleb offers cutting-edge formwork solutions. This comprehensive guide explores everything about large panel formwork — its definition, types, benefits, drawbacks, costs, and selection tips. For more on concrete formwork, click here.
Advantages and Disadvantages of Large Panel Formwork
Advantages
- High construction speed: Large panels reduce assembly and dismantling time — ideal for time-sensitive projects.
- Superior concrete finish: Produces smooth, uniform surfaces, often eliminating the need for plastering.
- Cost savings: Reduced labor and material costs thanks to faster execution and minimal finishing.
- Earthquake & fire resistance: Seamless structures offer enhanced resistance to lateral forces.
- Design flexibility: Pre-designed openings for doors, windows, and utilities.
- Durability: Metal panels are reusable across multiple projects with proper maintenance.
Disadvantages
- High initial cost: Quality metal panels and accessories raise upfront cost vs. traditional modular systems.
- Specialized labor: Requires trained workers and equipment like cranes for installation.
- Limited for small projects: Less cost-effective for small or highly complex designs.

Components of a Large Panel Formwork System
- Main panels: Large steel panels (usually 3–5 mm plate) forming the main surface; typically 1.5–7.5 tons.
- Brackets: Connect panels and bear concrete pressure.
- Chutes: Tubes that direct concrete into the formwork.
- Tie rods: Connect opposite panels and prevent the forms from opening during the pour.
- Plumbing jacks (prop jacks): Adjust verticality and ensure a level structure.
- Adjusting screws: Secure connections and create system integrity.
- Modular scaffolding tubes: Move and install panels on upper floors.
- Accessories: Clamps and pins to boost rigidity.
- Lifting hooks: Easy panel handling by crane.
Production & Execution: From Design to Pouring
1) Design
Design is done with software such as AutoCAD and Tekla, accounting for concrete pressure and structural dimensions.
2) Production
Steel forms are produced with CO2 welding, while polymer forms are made by plastic injection.
3) Installation
Installation uses cranes and modular scaffolding.
4) Pouring & stripping
After pouring (C30 or C40), forms are stripped after 7–14 days and prepared for reuse.
Step-by-step on-site execution
- Design & planning: Define opening locations and select panels by project size and weight.
- Site preparation: Prepare the foundation, level the surface, and install plumbing jacks.
- Form installation: Move panels with a crane; connect with brackets and tie rods.
- Pouring: Direct concrete through chutes and use a vibrator for proper compaction.
- Stripping: After initial set (24–48 h), strip carefully and move to the next floor.
- Quality control: Check wall alignment and surface quality; fix any defects.
Applications of Large Panel Formwork
- Residential projects: Towers and mass-housing complexes, especially in large cities.
- Commercial projects: Malls, hotels, and office buildings.
- Industrial infrastructure: Dams, bridges, and facilities needing seamless casting.
- Airports & metro stations: Large structures requiring high strength.
How Large Panel Formwork Saves Money
