The hot-dip galvanized steel profile elements can be assembled into planar structural units through bolting. Such structures can include walls, roof structures, floor structures, and beams. The spatial assembly and bracing of these structural units form the building.

1. Wall Structure

The wall structure consists of horizontal guide rails with a C140 profile at the top and bottom, with vertical C140 profile wall frame columns placed approximately every 500~600 mm, which are connected to each other via rivets through their straps. A vertical wall frame column must be used under concentrated loads (e.g., roof support structure). In case of larger loads, the wall frame elements need to be doubled. The wall frame columns are supported against buckling in the plane of the beam and against torsional buckling by the Rigips Glasrock or OSB cladding screwed onto the outer and inner sides of the wall. That is, the Rigips Glasroc or OSB cladding must be attached to each wall frame element with self-drilling screws. After assembly and on-site erection, the wall panels must be secured to the existing base structure with mechanical dowels. The wall panels are connected to each other with self-drilling screws and additional connector plates. Between the vertical wall frame columns, K-bracing or diagonal bracing is created.

2. Beams

The bridging of openings in wall panels is always created with a built-in truss support in the panel, at the desired length and necessary height. The truss support consists of parallel lower and upper belts and intermediate truss rods, each element made of C140 profile. If the bridging beam is subjected to concentrated force, the connection point of the truss support must always fall on a network point (intersection of truss rod and belt rod).

3. Floor Structure

In the case of multi-storey buildings, there is the possibility of designing lightweight floor structures. The floor structure consists of truss supports arranged side by side. The truss supports are made up of parallel lower and upper belts and intermediate inclined truss rods, with each element made of C140 profile. The supports should be designed and arranged side by side depending on the span, structural height, and load. The static frame of the floor supports is fundamentally a two-support beam, but multisupport or cantilever structures can also be designed.

4. Roof Structure

The roof structure consists of truss supports arranged side by side. The lower and upper belts of the truss support, as well as its inclined truss rods, are also made of C140 section. The roof supports can be placed on top of lightweight framed walls, or on hotrolled steel structures, or other traditional vertical support structures. The static framework of the roof supports is fundamentally a two-supported beam, but multi-supported or cantilever structures can also be easily designed. The distance between the trusses should be determined based on the span, structural height, and load. A vertical truss element design should be applied at the support of the beam, depending on the magnitude of the force transfer, by doubling the truss element. Hipped roof structures can be designed, as well as the connection of different roof surfaces. When creating hipped surfaces, beams of varying heights should be placed next to each other. The interconnected trusses should be connected to each other using bent connection plates. The lower and upper belts of the trusses are supported perpendicularly by the disc-like Rigips Glasroc board cladding, meaning that the truss is laterally supported through its belts; however, the truss rods have no lateral support and must be sized for spatial twisting. The Rigips Glasroc board cladding must be attached to each truss.

5. Secondary Structures

Structural elements with a C140 profile can also be used as secondary load-bearing structures.

They can be used in a two-supported or multi-supported configuration for receiving roof cladding, fixed to existing structures as purlins.

Additionally, when used as a vertical structure, they can also serve as facade walls or internal partitions.
