Supporting components for formwork and reinforcement

Sacrificial components are used when preparing formwork and during reinforcement work. This group includes spacers, supports and protective caps used to maintain the required distance between reinforcing bars and the concrete surface. Depending on the type of project, models are selected according to the required height and intended application. These accessories help maintain the correct position of reinforcement meshes and supports during concreting.
The range also includes products designed to protect exposed rebar ends and support safe organisation on the construction site. Safety caps and reinforcement spacers are used on projects where both safety requirements and correct positioning of structural components must be maintained. Plastic solutions are used in both smaller projects and larger reinforced concrete structures.

Sacrificial formwork for concrete works

Sacrificial formwork is used when constructing concrete elements that remain permanently embedded in the structure after installation work is completed. This solution makes it easier to create stable forms and reduces the time required to dismantle individual parts of the system. Sacrificial formwork is used, among other applications, for foundations, columns and slabs where specific technical requirements must be maintained.

The range also includes slab spacer bars and triangular chamfer strips used for forming edges and preparing construction joints. These elements help maintain the correct line of concreting and support the durability of the finished structure. Their use allows the surface to be prepared more precisely for subsequent stages of work.

Accessories for stable installation

Accessories used during concreting support the correct installation of reinforcement and positioning of formwork. The range includes plugs, tie rods and nuts used to secure service openings and maintain the required spacing between structural elements. The formwork manufacturer offers solutions suited to various systems used on construction sites.

The quality of materials used in the production of plastic components is also important. Properly selected accessories make installation work easier and support the long-term durability of the structure. Thanks to the use of universal solutions, they can be applied across a wide range of construction projects.
