Circular Column Formwork SK 100 is designed for constructing columns with a circular cross-section.
For the creation of curved or oval-shaped columns, the SK 100 system can be combined with Varimax and Ringform circular formwork.
The system consists of semi-circular formwork panels with standard diameters ranging from 30 cm to 130 cm in 10 cm increments.
The semi-circular elements are connected using built-in connectors — no additional fastening components are required.
Panels are available in three standard heights: 50 cm, 100 cm, and 200 cm, which can be stacked vertically to achieve any desired column height.
High-strength formwork
Permissible pressure of freshly poured concrete:
-
Up to D = 600 mm — 150 kN/m²
-
Up to D = 800 mm — 100 kN/m²
-
Up to D = 1300 mm — 80 kN/m²
Ease of use and planning
-
Only three standard panel heights and eleven standard diameters (in 10 cm increments) make planning and assembly simple;
-
Custom diameters up to 200 cm available upon client request;
-
All connectors are integrated, and accessories easily fit into grooves and tighten quickly, ensuring efficient construction and maximum performance.
Cost efficiency
-
Fast concreting process;
-
Preassembled blocks minimize crane use;
-
When using only two semi-circular sections per column, assembly and stripping times are optimized;
-
High reusability reduces long-term costs;
-
Quick cleaning lowers maintenance expenses;
-
Powder-coated steel construction extends the system’s service life;
-
High-quality concrete surface minimizes finishing work requirements.
Safety in use
Concreting brackets, push-pull props, and other accessories ensure the safety and ease of operation of the system.
