Primary framing

The primary framing includes transverse steel frames. The steel frames may have clear span dimensions (external dimension of the steel structure) from 8 to 60 m and heights from 3 to 12 m. The roof slope is between 6 % and 40 %. There are no limits on the total length of the building.  Centre distance from frame to frame may vary from 4 to 9 m. Construction of buildings with bigger clear span – up to 100 m - is also possible without the supportofintermediate columns and with up to 20 m height.  

Annexes, canopies, terraces, roof extensions (eaves), parapets and other architectural and functional additions can be added to the main building.

The elements of the main frames - rafters and columns - are formed by ready hot-rolled profiles or welded H shapes. Depending on the design and technological requirements the implementation by trusses is also possible. Frame joints and all other erection joints are fixed by bolts.

Roof Systems

TRS Roof System

TRS Roof System

                                                                                     This roof system consists of steel "sandwich" panels, which combine many technical and economical advantages in the construction of thermal and weathertighness coatings. They are easy to install and offer excellent insulation.

Consists of:

  • Two galvanized steel panel, custom colour
  • Filling - polyurethane or mineral wool with different thickness

Advantages:

  • Additional sealing and life time extension is provided due to a butyl strip used in all parts with panel-to-panel contact
  • With special care to parts where a thermal bridge is possible to appear by usage of  additional sealing insulation against condensation on the inner surfaces
  • The system has a wide variety of equipment completions - gutters, drain-pipes, ridge and cornice elements
  • There is a large range of accessories, fully compatible with the profile, ensuring optimum weathertightness and pleasing aesthetics – translucent panels, skylights, smoke vents, roofjacks, etc.

PR Roof System

PR Roof System

Suitable for all buildings types, it provides good thermal insulation and excellent weathertightness. The erection is relatively slow but is economical, practical and functional.

Consists of:

  • Profiled galvanized steel panel, custom colour
  • Mineral wool with different thickness
  • Vapour barrier
  • Isoblock – insulating strips that minimize thermal bridges  

Advantages:

  • Provides excellent thermal insulation, cheaper than the "sandwich" panels
  • Additional sealing and life time extension is provided due to a butyl strip used in all parts with panel-to-panel contact
  • It has good fire safety features
  • Prevents from condensation on the inner surface unlike the “naked” steel panel
  • The system has a wide variety of equipment completions - gutters, drain-pipes, ridge and cornice elements

There is a large range of accessories, fully compatible with the profile, ensuring optimum weathertightness and pleasing aesthetics – translucent panels, skylights, smoke vents, roofjacks, etc.

LMR600 Roof System

LMR600 Roof System

Consists of:

  • Panels with 600 mm width and 50 mm height of the corrugation
  • Mineral wool with different thickness
  • Vapour barrier
  • Isoblock  – insulating strips that minimize thermal bridges  

Advantages:

  • Clip-system allowing free expansion and contraction of the roof lathing, which prevents from the occurrence of tension in the roof construction
  • Durable, completely weathertight
  • Pinned at 3600  with double-bending seam using a special sewing machine
  • The panels are connected to the secondary structure with a special clip
  • Once "sewn" the entire roof becomes a monolithic metal membrane
  • Less thermal bridges thanks to the clip-system
  • No drilling of the panel and use of additional supports

LTH Roof System

LTH Roof System

This system is performed by high profiled LT steel panels mounted directly on the primary frame. It saves the usage of purlins. Tensions in the roof are absorbed by horizontal pipes mounted in the lower flank of the rafter. There are no restrictions in the insulation thickness.

Consists of:

  • Weathertightness with reinforced TPO or PVC membrane
  • Mineral wool with 150 kg/m3 bulk density and varying thickness
  • High-profiled galvanized LT steel panel

Advantages:

  • Allows small roof slopes
  • Suitable for buildings with parapet  
  • Simple and quick installation
  • The system has a wide range of equipment completions - gutters, drain-pipes, ridge and cornice elements
  • Easy integration of all kinds of accessories - translucent panels, skylights, smoke vents, roofjacks, etc.

Wall systems

WCL Wall System

WCL Wall System

The system consists of steel "sandwich" panels with a variety of colours and profiles of the internal and external steel panel. Polyurethane and mineral wool filling is used, depending on the aesthetic, thermal and fire safety requirements for each site. Usually comes with invisible bolts, which provides excellent joint sealing and extended life time of the panel. They are easily installed and are aesthetical solution.

Consists of:

  • Two galvanized steel panels, custom colour
  • Filling - polyurethane or mineral wool with different thickness

Advantages:

  • Additional joint sealing and life time extension is provided due to reinforced aluminum foil strips. This protects from moisture coming from vapour in the polyurethane foam. Spongy rubber sealing creates a better air seal
  • With special care to parts, where a thermal bridge is possible to appear, by usage of  additional sealing insulation against condensation on the inner surfaces

The system comes with a wide variety of equipment completions – corners and building plinth profiles, forming of doors and windows with cornices

РА Wall System

РА Wall System

Suitable for all buildings types, it provides good thermal insulation and weathertightness. The erection is relatively slow but is economical, practical and functional.

  • Provides excellent thermal insulation, cheaper than the "sandwich" panels
  • It has good fire safety features
  • Prevents from condensation on the inner surface unlike the “naked” steel panel
  • The system has a wide variety of equipment completions - gutters, drain-pipes, ridge and cornice elements - corners and building plinth profiles, forming of doors and windows with cornices
  • Allows combinations with all modern construction materials
