Wall formwork panel FF20

slabplywood

Overview
FF20 is a modular wall formwork system with a 25 cm element grid, designed for efficient planning, fast assembly and high-quality fair-faced concrete finishes.

Delivered to your site ready for use

• Supplied as pre‑assembled standard elements for immediate on-site use
• Combines timber‑beam formwork benefits with the precision of a framed, grid-based system to meet high concrete finish requirements
• Practical element grid allows easy adaptation to varying wall geometries
• Elements available for rent, economical for limited reuse
• Project-specific facing possible — compatible with a range of form-plys

Maximised utilisation of equipment

• 25 cm increment grid simplifies planning, cutting and logistics on site
• Only a few element widths reduce inventory and rental costs

Rapid forming

• Practical inter-element connections enable quick and secure vertical stacking
• Integral centring stacking flange facilitates safe and fast assembly
• FF20 formwork element connector provides crane‑safe, tight, non‑slip joins

Comprehensive workplace safety

• Safe vertical access with the Ladder system XS
• Perimeter workplace protection with Platform system Xsafe plus
• Accessories (panel struts, lifting/repositioning devices, etc.) support safe handling

System — The FF20 elements

• Coordinated panel formats for optimal material utilisation
• 25 cm grid with only four widths and three heights simplifies design and logistics
• Accessories can be fixed to transverse walings across the full element width without mandatory fixing points
• Standard facing: three‑ply sheets; custom facings possible

Height grid
Standard FF20 elements combine with stacking elements to achieve practical formwork heights up to 6.50 m. The 2.75 m elements are symmetrical and reversible for flexible use.

Utilisation — Vertical stacking / inter-element connections

• Fastening bolt FF20 with star grip nut centres and connects vertically stacked elements in a slippage‑free manner; turn‑lock eases nut tightening
• Formwork element connector FF20/50 Z clamps assembled elements tightly to create crane‑safe, non‑slip joins
• Pre‑assembled elements link in a 25 cm grid for optimum adaptation to the structure

Corners, pillars and horizontal use

• Right‑angled corners can be formed using modular elements, even with wall thicknesses up to 60 cm
• FF20 hinged corners provide solutions for acute and obtuse angles
• Suitable for wall pillars
• Can be dimensioned for horizontal use — pour slabs and walls in one operation in fair‑faced concrete quality
