We have been developing our unique steel structure, the LLENTAB system, since 1972.
LLENTAB delivers buildings of different sizes, structures, roof slopes, insulation, cladding, fire resistance and colour combinations. The permanent search for first-rate technical solutions and development of production facilities makes us one of the leading designers and producers of steel buildings in Europe. Profiles produced on high-tech lines enable us to deliver steel structures of buildings with unlimited sizes and spans of up to 100 m. Galvanised cold-bent profiles guarantee long-lasting quality and low steel consumption. Assembly with bolts permits the fast erection of structures and long-lasting protection against steel corrosion. All our profiles have holes pre-punched during the production process. This, along with the labelling of each profile, ensures correct assembly. LLENTAB uses profiles with thicknesses from 1.5 up to 7 mm. High-strength steel is used for all profiles up to a thickness of 7 mm. Our profiles are produced from hot-dip galvanised steel delivered to us in coils. For thinner profiles (up to 2 mm), a Z275 layer is used, while for the rest Z450 is standard. Profiles are roll-formed or bent into a variety of sizes and the shapes are Z (mainly for purlins and wall racks), C (for trusses, pillars and frame elements) and Ω (for the top and bottom flanges of the frame).

Pillars
LLENTAB pillars are made from C profiles, starting with two connected C profiles up to truss pillars for very high buildings and halls with crane runways. Standard pillar types:
2xC pillars
- 2xC170: thickness 3/4/5/6 mm
- 2xC250: thickness 3/4/5/6 mm
- 2xC300: thickness 5/6 mm
- 2xC360: thickness 4/5/6 mm
- 2xC380: thickness 6 mm
QUADRO (4xC) pillars
- 4xC360: thickness 4/5/6 mm
Truss pillars (2 pairs of 2xC pillars at a distance of 500~1200 mm)
- 4xC170: thickness 3/4/5/6 mm
- 4xC250: thickness 3/4/5/6 mm
- Can be a combination of 170 mm and 250 mm profiles

Roof frame
The flexibility of the LLENTAB system creates the possibility of delivering different roof slopes according to customer needs. LLENTAB steel buildings can be designed with an insulated or uninsulated roof, with a pitched roof or mono-pitch roof (single slope) and with a roof slope of 1°, 2°, 3°, 4°, 6°, 7°, 11°, 14°, 17° or 21°. LLENTAB delivers several types of flat membrane roofs, panel roofs and ‘plate-wool-plate’ roofs with high insulation values and exceptional water and corrosion resistance.
Walls
Gable walls may be load-bearing or overhanging. Customise your building by choosing between uninsulated or insulated walls. Choose the appearance of your panels, which can be mounted vertically or horizontally.
