Design software for composite sheets

What are composite sheets?

Composite sheets are designed to function as part of a concrete mezzanine floor structure; they act as a casting mold and reinforcement, partially or completely replacing tensile reinforcement. Composite sheets are steel profile sheets that serve as a base for concrete casting and, together with the concrete, form a load-bearing composite structure. The sheet’s embossments ensure concrete adhesion. The best properties of steel and concrete are combined into a structure that is both strong and material-efficient.

Thanks to the composite structure, the mezzanine floor can be implemented more lightly than many traditional solutions while maintaining high load-bearing capacity and a long service life.

A fast and practical construction solution for mezzanine floors

Weckman composite sheets function as a mold during casting, significantly reducing the need for separate formwork structures. During concrete casting, the sheet forms a load-bearing base and structure to which the concrete adheres effectively.

Benefits on-site:

• fewer work stages
• faster installation
• shorter construction times
• more efficient use of site resources
• reduced consumption of rebar

When the mezzanine floor is quickly ready for use, other work stages can also proceed sooner.

Less formwork

A fast and practical construction solution for mezzanine floors

In traditional cast-in-place structures, a significant portion of working time is spent building, supporting, and dismantling molds.

With composite sheets:

• the amount of formwork is reduced
• site logistical needs are decreased
• fewer temporary structures are needed on-site

This is reflected in both the schedule and the total costs.

A cost-effective solution

Total construction costs are not made up of material prices alone.

Weckman composite sheets help you save on:

• working time
• installation costs
• formwork costs
• site overheads

With fewer work stages, construction progresses more predictably and efficiently.

Lightweight yet load-bearing structure

Composite sheets combine the benefits of lightweight steel and strong concrete.

As a result, composite sheets achieve:

• excellent load-bearing capacity
• efficient spans
• structural reliability
• a material-efficient mezzanine floor solution

Lightweight composite sheets also facilitate transport and installation on-site.

A safer construction site

Once installed, the composite sheet quickly forms a continuous working platform. This simplifies site arrangements and supports safe working during construction.

A well-designed composite sheet structure can reduce the temporary structures and extra work stages needed on-site.

Where are composite sheets used?

Weckman composite sheets are suitable for a wide range of buildings and mezzanine floor structures in both new builds and renovation projects.

• commercial and retail buildings
• industrial buildings
• logistics centers
• parking facilities
• public buildings
• residential buildings
• office buildings

The solution is particularly suited to projects where construction speed, cost-effectiveness, and structural performance are key objectives.
