As part of general contracting for the construction of halls, we carry out prefabrication of steel structures in the production line. We also produce plate girders to order. It is a process of producing steel structural elements that are used to construct buildings designed based on a steel frame.
Solid structural profiles supplied by steel mills and metal mills, such as angles, T-sections, C-sections, and sheets, are not sufficient to construct building frame columns, girders or spans. For many decades, the so-called plate girders.
In the production process of these elements, the harmonized standard EN 1090-1:2009+A1:2011 applies
Product description:
The production of plate girders is based on wear optimization in the design process
steel, and also in terms of cross-sectional dimensions, but also the step distribution of these
cross-sections along the length of the beam and the type of material
Types of plate girders produced:
- plate girders for connection with a reinforced concrete slab;
- plate girders drilled in the web (openwork);
- plate girders with variable cross-section height;
- crane girders.
Example of design characteristics:
Span range:
From 3 m to 18 m. It is possible to introduce an additional screw connection (contact
assembly), to avoid oversized transport.
Dimensional tolerances according to: EN 1090-2 annex D2,
Steel grade: S235JR; S235J0; S235J2; S375JR; S275J0; S275J2; S355JR; S355J0; S355J2, acc
10025-2 or to be agreed
Anti-corrosion protection: painted according to EN ISO 12944 or hot-dip galvanizing
Fire protection: up to class R120
Technical execution conditions:
can be made with a cutting accuracy of up to 0.5 mm;
firing any shape, minimizing the cutting width to 2 mm and
possibility of using long sections of sheets, even over 6 meters long, at the stage
firing, which allows cutting more complex or smaller patterns
elements on one sheet of metal, without the need to weld them from several elements
cut from different sheets;
precise cutting to the required length and angle using a specialized saw –
the edges of the cut elements are immediately properly and precisely processed (without deviation from
plane of the elements, without unevenness and burrs that are dangerous for installers) i
do not require additional grinding service;
Testing the quality of welds and welded joints using professional and precise equipment
for MT and UT tests;
Guaranteed high quality thanks to the ability to fully supervise the entire process of sandblasting and painting elements thanks to our own shot blasting chamber and paint shop.
Execution: Execution in accordance with the documentation and EN 1090-2:2018, execution class EXC3.
Plate girders, i.e. a series of interconnected sheets of metal sheets, which in steel structures successfully replace solid elements such as T-beams and I-beams. They have been used for a very long time, initially as a replacement for solid structural elements to obtain the required strength, as trusses, girders or entire spans. The use of steel hall structures to produce elements for bridge construction significantly expands the range of applications by increasing the number of possible elements such a structure can consist of. For a long time, plate girders have been used in the construction of bridges and spans supporting roofs, terraces or platforms.
Elements for the construction of girders and spans, welded or riveted from sheet metal (plasma cut by burning)
Plate girders are necessary for the construction of durable load-bearing elements.
Used in span structures supporting roofs of industrial halls, in railways to maintain power traction structures, in power poles, in so-called bridges. plate girders, in utility structures, e.g. overhead cranes, in the shipbuilding industry.
Manufactured from steel sheets of various thickness and strength.
There is no better way to effectively strengthen a structure than to use plate girders. Especially when it comes to large and unusual cross-sections of load-bearing profiles, made of plate girders cannot be replaced by welded ones made of solid profiles (they are cheaper and lighter than the mentioned ready-made profiles). From a design and application point of view, the resulting elements have much greater strength while reducing weight.
