TOPEC Slab Formwork System for Concrete Construction

Panel Material & Weight

• Frame:
  Aluminium alloy (14cm height), powder-coated for corrosion resistance
• Panel:
  10mm plywood
• Weight:
  • 180×90cm = 22.2kg
  • 180×180cm = 47.1kg

Load Capacity & Applicable Slabs

• Maximum slab thickness:
  500mm (standard) / 750mm (60cm wide panel)
• Standard props:
  EUROPLUSnew (20kN / 30kN), compatible with GASS / old Hünnebeck props
• Allowable deflection:
  Complies with DIN 18202 standard

Efficiency & Applicable Height

Assembly & disassembly efficiency:
0.20–0.40 h/㎡ (labor)

Ground operation height:
≤ 3.5m (3 steps: hook → lift → support)

Applicable floor height:
≤ 5.8m (with TOPEC lifting frame)

System Composition (2 Core Components + Accessories)

Core Components

1. Panels

Aluminium frame with laminated film; large panels reduce joints and improve surface quality

2. Steel Props

EUROPLUSnew props with quick-drop mechanism for efficient support and stripping

Key Accessories

Drophead (optional):
Early stripping head allows panel removal when concrete reaches 50% strength, while props remain in place

Adjustable beams / corner fittings:
Adapt to column sides, wall corners, and irregular layouts

PROTECTO edge protection:
Integrated edge safety protection system

Application Scenarios

Residential & Commercial Buildings

• High-rise and multi-storey slab construction
• Suitable slab thickness: 100–500mm

Public Buildings

• Parking garages
• Factories
• Schools and teaching buildings
• Hospitals

Special Structures

• Drop floors
• Low-curvature inclined slabs
• Areas with dense column layouts

Combined Systems

• Works with TOPMAX table formwork for rapid infill construction

Core Advantages

Fast Installation

Large 1.8×1.8m panels allow two workers to assemble and dismantle the system in just three steps without aerial work platforms

Lightweight Design

Aluminium panels reduce weight significantly; 90cm-wide panels can be handled by a single worker

Flexible Adjustment

Adjustable panels (55–90cm) provide easy adaptation around columns and irregular areas

Cost Efficiency

Early stripping system (Drophead) shortens construction cycles by up to 40% and reduces material turnover costs

High-Quality Finish

Ensures smooth, even concrete surfaces, suitable for fair-faced concrete applications

Comparison with Traditional Formwork

Traditional Wooden / Steel Formwork

• Multiple components
• Heavy and labor-intensive
• Requires on-site cutting
• Lower efficiency: 0.8–1.2 h/㎡

Aluminium Slab Formwork (TOPEC System)

• Simplified system: panels + props only
• No on-site cutting required
• 2–3× higher efficiency
• Reusable for 20–30 cycles

FAQ

What is the maximum slab thickness supported?

The system supports up to 500mm slab thickness as standard and up to 750mm with 60cm wide panels.

Can one person handle the panels?

Yes, 90cm-wide aluminium panels are lightweight enough for single-person handling.

What is the advantage of the Drophead system?

It allows early stripping of panels while keeping props in place, reducing construction time and improving efficiency.

Is the system compatible with other props?

Yes, it is compatible with EUROPLUSnew, GASS, and old Hünnebeck props.

What types of projects is this system suitable for?

It is suitable for residential, commercial, public buildings, and complex slab structures.

How efficient is the system compared to traditional formwork?

It improves efficiency by 2–3 times and significantly reduces labor requirements.
