Design of bridges and artificial structures
UKRSTEELSPECIALCONSTRUCTION has its own structure and complexity. Motorway, railway and foot bridges as well as overpasses
Bridge design is one of the most complex tasks due to the uniqueness of each structure. The whole set of works on design is performed by the experienced experts employing innovative software based on Bocad, StruCAD, Tekla, AutoCAD etc
Design group independently develops all the sections of documentation including estimate documentation and structure calculation in the modern calculation systems. Such approach ensures the quality and timeliness of work performance.
Generation of metal structure drawings and detail metal structure drawings
UKRSTEELSPECIALCONSTRUCTION design group performs design works on all types of metal structures including as follows:
Generation of metal structure drawings and detail metal structure drawings
Adaption of metal structure drawings and detail metal structure drawings generated by overseas companies
Field and engineering supervision as well as in-service control
Provisional calculation of metal specific consumption
Preparation of Technical Assignment for design
Generation of metal structure drawings according to foreign regulations (Eurocode etc.)
The main potential of our company is people. Our experts have a huge experience in manufacturing metal structures of all types and complexity manufactured for the various industrial sectors as follows:
Metal structures for equipment
Building and construction frameworks
Production-line items and many other products
Our experts have higher qualification and all required licenses.
UKRSTEELSPECIALCONSTRUCTION manufacturing facilities are equipped with all kinds of the equipment for manufacturing metal structures of all types. We use all types and grades of rolled steel products and steel sections including pipes having different diameters. The company experts are capable performing all types of welding including full penetration welding of steel having thickness up to 300 mm. We produce custom-designed pipes. The area of our manufacturing facilities (shops) exceeds 120,000 sq. m. These facilities are equipped with shop cranes having lifting capacity up to 200 tones. We perform a fit-up assembly of the components having length up to 140 m inside the shops. If the length of the components is up to 240 m, a fit-up assembly is performed on special sites outside the shops.
Main production stages are as follows
Straightening of sheets is performed on flat-rolled product pre-straightening rolls manufactured by Nichimen, Japan. Thickness of sheets is from 6 to 40 mm.
Cleaning and priming
Cleaning and priming of flat-rolled products and sections are performed on two shot-blasting machines manufactured by Fogel and Nichimen. After priming, each sheet is marked with cutting card number. The equipment capacity enables to perform cleaning and priming of approximately 17,300 sheets and 22,000 sections per year.
Cutting of sheet metal components having sheet thickness from 5mm to 24 mm and overall dimensions of 3.2х16m is performed under water using portal plasma cutting machines NUMORREX NXB-4500 and TELEREX TXB-10200. Web stiffener cutting is performed using oxygen cutting machine MESSER GRIESHEIM. Gas cutting machines TELEREX TXA-50 and TELEREX TXA-80 enable to cut sheets having thickness from 25mm to 150mm.
Bending of flat-rolled products and sections with the biggest sheet width of 16m and thickness of 55mm is performed using Nichimen rolls and applying a press hydraulic force of 350 t, 800 t and 1250 t.
Assembly and welding
Assembly and welding of metal structures are performed employing state-of-the-art equipment ESAB and Kemppi and using high quality welding materials. Automatic submerged arc welding and gas-shielded welding using two types of welding wires are performed by a tractor-type welding machine A2-Multitrac and A6- Mastertrac. Machine welding is performed by means of semi-automatic machines МЕК-20W.
Welding process has been certified by Germanischer Lloyd. The engineers and technical personnel working at the plant have been qualified as the international experts of welding engineering. Welding processes have been developed pursuant to the European and International Standards and Rules, and verified by the International Association of Classification Societies (LR, DNV and РМРС).
The equipment of the assembly and welding shop enables to produce box units with weight up to 200 tons using overhead cranes with lifting capacity from 5 to 125 tons. Enlargement of sections (if required) having weight of up to 1500 t and length up to 150 m is performed on near building ways site equipped with 2 overhead cranes having lifting capacity of 900 tons each. The sections and units are transported by transborder bridge Commetto having lifting capacity of 350 tons. The transborder bridge is equipped with on-board computers capable of determining the cargo gravity center in the automatic mode. The transportation can also be performed by two trailers Scheuerle having lifting capacity of 320 tons each (the transportation of units having weight up to 600 tons is possible in the dual mode).
Cleaning and painting
Cleaning and painting are performed in a spray paint booth of a tunnel type having the overall dimensions of 24 х 120 m. The booth is equipped with cleaning and painting devices made by KISS. According to the Swedish standards, abrasive cleaning is performed up to cleaning degree Sа 2.5. Painting of the finished metal structures is performed with subsequent applying of any industrial paint and anti-corrosion coating. Anti-corrosion protection of metal structures is secured by using the paintwork materials made by the leading European companies Hempel, Jotun, Sigma Coatings, and International Paint.
UKRSTEELSPECIALCONSTRUCTION pays a special attention to the quality of metal structures at all production stages.
The product quality is controlled by UKRSTEELSPECIALCONSTRUCTION experts with the involvement of the E.O. Paton Electric Welding Institute in Kyiv and Independent Bridge Inspection of Ukraine in strict adherence to the requirements of design and International Standards.
For controlling the quality, we also use the capabilities of our own laboratories where we carry out control of various types: steel spectral analysis as well as capillary, radiographic, ultrasound, magnetic, chemical and mechanical analysis, etc. Thus, we ensure the quality of the product produced.
On Customer’s request, we can inspect and study the existing metal structures as well as make calculation and analysis of metal structure wearing, and provide the findings.
High requirements, imposed by the market and customers, motivate carrying out a professional control over all production cycles, timings and phasing of the finished product delivery and installation works.
Project Management Department successfully copes with all tasks mentioned above.
