  • fabrication workshop completing our capacity in terms of welding and assembling
  • mechanical workshops for special pieces machining
  • galvanization of structural steelwork

 

Sawing, Bending and Drilling

Sawing

Cold sawing by circular blade with a diameter up  to 1510 mm, adapted to the whole section range. Straight and bias cutting possible about both axis with  reduced tolerances concerning length and angle.

Bending

Bending belongs to the specialty of our workmanship.  Whether it's for architectural or mechanical reasons,  we are able to establish cambering according to circular,  parabolic or curves determined by points and along  both strong and weak axis.

Each workshop has its own hydraulic press with the  possibility to cover the whole section range. The bending  is done by cold forming, with a special attention to  the mechanical requirements of the steel material.

The hydraulic press are also used to perform double  straightening of the sections to ensure reduced tolerances  than the ones provided through the rolling process, in order  to meet stricter requirements for specific projects. We can bend all types of H sections with a maximum length of 40 m.

Drilling

Automatic and manual drilling robots for thickness  up to 140 mm and diameter up to 120 mm. Reduced tolerances concerning hole dimensions  and positioning.

 

Flame cutting

 

In our workshops we have various oxygen cutting  as well as plasma cutting facilities, used in function  of the type of required shapes and thickness.  Whereas oxygen cutting is used for thicknesses  between 8 and 140 mm, plasma cutting is used  between 5 and 25 mm.

Flame cutting robot

Our flame cutting robot (oxygen + acetylene) able to  operate around 6 axes, allows complex bevels for the  joining of the beams. It is also used to fabricate T sections (flame cut into two beams along its axis, in symmetrical  or asymmetrical shape) or to operate holes with large  diameters. The robot can accommodate beams with  a maximum length of 40 meters.

Oxygen & Plasma cutting table

Four heads cutting machine (2 for oxygen cutting, 2 for  plasma cutting) dedicated to perform cutting in the lying beams web. Typically used for castellated beams or other types of special web fabrication. It can accommodate  beams with a maximum length of 32 meters.

Milling

Our customer's are interested in operating heavy beams  milling at customized shapes

 

Welding

Automatic Welding

An automatic submerged arc welding machine is available with 2x1000A generators. The machine can perform welding with speeds up to 60 cm / min and a deposit rate up to 12 kg / hour. Automatic seam tracking allows the adaptation to any kind  of shapes. Weldable width is up to 2000 mm, the optimal horizontal run is up to 18000 mm, whereas extension may be  studied case by case. It is dedicated to the fabrication of Slim floor beams, box girders or cross columns.

Special pre-assembly

For specific projects, we can study the pre-assembling of fabricated structure inside the workshop. This pre-assembling  may be requested to verify the perfect match of the fabricated parts before the final assembly on the construction site.  We have experience in this kind of pre-assemblies for  bridges as well as for components of building structures.

 

Surface treatment

 

In order to protect the steel structures from aggressive  environmental conditions, we are able to offer corrosion  protection treatment of the steel surface.
The surface treatment processes play a very important  role in the appearance, function and life of the product.Surface preparation is the essential first stage treatment  of a steel substrate before the application of any coating,  and is widely accepted as being a key factor to achieve the  success of a corrosion protection system over the time.
Paint is the most commonly used material to protect steel. Paint systems for steel structures have developed over the years to comply with industrial environmental legislation  and in response to demands from bridge and building  owners for improved durability performance.

Beside corrosion protection, we can also offer the  application of fire protection coating according to  the latest technical standards.

 

We are specialized in the application of complete painting systems according to ISO EN 12944,  Acqpa certification, DB-TL, ZTV-Kor or eventually other specifications on request.

Bridge applications

Eurostructures Beam Finishing Centre has developed since its beginnings an outstanding expertise in the finishing of bridges girders. Structural shapes are a traditional competitive technology used since over a century in the railway infrastructure for small and medium span bridges.

The development of high strength steel has enhanced the competitiveness of steel-concrete composite decks also for road-bridges, which are nowadays a widespread technology all over the world. We are also involved in the realization of small footbridges as overpasses for roads or rail infrastructures.

Filler beam bridge decks

The filler beam bridge is a widespread technology, used in several countries (application: about 90% railway bridges,10% road bridges). It consists of a concrete slab with longitudinal reinforcement made of rolled beams, with usual spans between 10 and 25 m. The filler beam bridges are in competition with pre-stressed concrete bridges, but they offer many advantages against concrete solutions, as:

  • The simple method of construction, which opens the tender to a large number of companies.
  • The thickness of the deck is the most slender amongst all deck typologies. Generally HEA, HEB or HEM sections are used, which are commercial sections readily available.

 

Filler beam deck for A4 access in Esch-sur-Alzette, Luxembourg

The filler beams deck is composed of closely spaced longitudinal beams. Welding on the site construction is usually not needed; the corrosion protection isnot necessary except for the bottom flange. The bending is easy to be determined.

Typical cross section of a railway bridge

The finishing work capacities for filler beams include the bending along both the strong and weak axis, the drilling of the beam web to allow the transversal reinforcement to pass through, and the corrosion protection of bottom flanges.

In addition to this, the accessory parts (support plates, stabilizing devices, etc…) are delivered to complete the offer for the constructional steelwork.

Downstand double-T sections composite bridge decks

The composite bridge is a concrete slab based on steel structure where the girders may be realized out of rolled sections. In the Eurostructures Beam Finishing Centre, we perform the rolled sections finishing works for the bridge girder, with high performance and efficiency, providing the shortest delivery time.

This type of deck is mainly used for road bridges, in which the span length is between 15 and 45 m. It offers many advantages versus concrete solutions:

  • their supports are smaller, so less intrusive in the landscape
  • deck steelwork can be pull back or cut up into “easily”moved sections and its steel can be recycled
  • their deck slabs are not thick and therefore lightweight

Choisy bridge, Villeneuve-Saint-Georges, France

Depending on the span bridge width ratio, twin girder or multi-girder decks may be chosen. To ensure structures stability, we may provide associated elements such as cross beams or bracing for the construction in the final phase.

WD7 and WD8 viaducts, Gdansk, Poland

Those elements need accurate work to be assembled together, and this may under given circumstances require a pre-assembling study before erection.

Shear studs connectors are used to connect the steel structure to the concrete slab. They are welded in the workshop to the main girders.

Half-through bridge decks

Overpass on A3 in Bettembourg, Luxembourg

Half-through decks are composed by two lateral main girders, with closely spaced cross girders connecting the lower chords. Cross beams are supporting the deck, which may be used for railway, roadway or footpath. Typically the concrete deck is designed to work compositely with the steelwork. For footbridges the deck can be with precast concrete plates or with wooden boards fixed on the steel structure.

Half-through bridge deck in Guenange, France

Eurostructures Beam Finishing Centre offers the fabrication of main girders as well as of cross girders out of rolled sections.

Main and cross girders assembling are done on the construction site by an external contractor.

In case of major bridges (e.g. span >25m), side main girders are done out of plated girders. In this case, Eurostructures delivers cross beams to a major steel contractor, offering cambering, painting and head preparation with delivery to the construction site.

Precobeam girder bridge decks

Precobeam – Prefabricated Composite Beam - is an innovative concept developed in various research projects over the past decade, entering now in the European construction practice.

Overpass on ÖBB line, Kratzerau, Austria (©: SSF Ingenieure)

A high-strength rolled H sections is cut into two T-sections. The T-sections are used as external reinforcement in prefabricated concrete girders. The cutting is performed in a special engineered way to ensure the steel concrete connection thanks to its special shape.

Precobeam is a technical innovation for short-span bridges making steel-reinforced concrete a very economical solution.

Prestressed steel girder bridge decks

The principle of this technology is the following:

  • fabricate an H rolled sections with a special curvature shape
  • prestress the steel girder by mechanical bending
  • encase the steel girder in a concrete prefabricated flange or slab
  • release the prestressing reinforced steel girder, which acts compositely with the reinforce concrete and put it under compression
  • associate the elements together to realize the whole piece through whole deck concreting

For special project requirements, prestressed steel girder bridges turn out to be the best adapted solution. We are able to offer fabricated steel girders and technical advices.

ACB® Cellular Beams

The use of cellular beams allows new forms of architectural expression. Structures are lightened and spans increased, pulling spaces together. This flexibility goes together with the functionality of allowing technical installations (pipes and ducts) to pass through the openings. The lightweight appearance of cellular beams, combined with their high strength, never ceases to inspire architects to new structural shapes.

Finishing

  • oxygen or plasma flame cutting of the shape
  • cambering of the cellular beams
  • assembling and welding
  • welding of shear studs connectors for composite constructions
  • openings filling to allow assembly joints
  • surface treatment – corrosion and / or fire protection

Angelina™ beams

Angelina™ beam is the realization of an architectural dream: A castellated beam with smooth and elegant shape of web openings which can be tailored-made.

The sinusoidal shape of the opening optimizes furthermore the load bearing resistance of the beams in respect to the Vierendeel effect, and allows fabrication cost reduction.

Finishing

  • flame cutting of the shape by oxygen or plasma
  • cambering of the Angelina™ beams
  • assembling and welding
  • welding of shear studs connectors for composite constructions
  • filling of the openings to allow assembly joints

Slim Floor beams

Developed by ArcelorMittal group, the composite“Slim Floor” concept is a fast, innovative and economical solution which combines concrete or composite slabs with built-in steel beams.

     

The design ingenuity lies in a special kind of girder whose lower flange is wider than the upper flange. This arrangement allows fitting the floor slabs directly onto the lower beam flange plate so that the two elements support cove area of flooring material.

Finishing

  • cambering of the beams
  • drilling of the web of the beams fitted to allow passage of reinforcement bars
  • assembling and welding of lower plate
  • if required, welding of stud shear connectors

Chamfering and heavy beam preparation

High-strength steel is the material of choice for tall buildings all around the world. Heavy H-rolled sections are mainly used for the columns bearing gravity loads, as well as for the outrigger systems for the wind and earthquake loads.The use of high-strength steel allows structural frames optimization and consequently cost reduction.

   

In combination with our heavy Jumbo profiles, we offer some finishing possibilities for the heavy elements in order to optimize the cooperation with the steel contractor.

Heavy beams are often straightened up after rolling to achieve stricter tolerances. We are equipped with oxygen-cutting and milling machines able to work on the whole thickness range. Furthermore, we can also offer heavy columns assembling in cross-shape or with cover plates to increase the load bearing capacity.

 

Finishing

  • beam double straightening to minimal tolerances
  • cut-to exact length
  • drilling and hole preparation in any thickness range
  • oxycutting of the weld preparation
  • beam end preparation for special connection details (e.g. outrigger truss systems)
  • assembling in form of cross or cover plate sections

Trusses

 

Truss structure for the runway crane in Belval still mill, Luxembourg

A truss is an assembly of steel members that are connected at their ends. Trusses are used since the beginning of the steel construction until our days for buildings, bridges and special structures. The principle of trusses consists of external forces acting on the nodes and resulting in forces on the tensile or compressive members.

Finishing

  • flame cutting of the structural shape by oxygen or plasma
  • drilling in the web / flanges of the beams to prepare for bolted connections
  • alternatively, beam end preparation
  • welding of gusset plates to ensure the connection of the truss members
  • eventually pre-assembly in workshop to verify the geometric consistency of the elements
  • surface treatment

Industrial halls & runway beams

Single storey buildings are often steel framed structures with metallic cladding. Large open spaces can be created, easy to maintain and flexible for future adaptation. The important load bearing capacity is an asset for installing powerful cranes for heavy pieces handling inside the hall.

    

Runway beams for industrial craneways

The use of hot rolled sections as runway beams is well established in the construction practice. With time, fatigue loads on runway beams are due to craneways running on them, increasing pressure on tiny welded parts. Rolled sections offer the possibility to avoid some of the critical details, enhancing the fatigue resistance of the structure.

Over the last years, Eurostructures Beam Finishing Centre made relevant projects with special developed sections such as HD sections with welded plates in form or double T hot-rolled sections with a hut in form of a U shape. In both cases the design choice is linked with the avoidance of having sensible fatigue details below the craneways rail, as well as ensuring relevant weak axis inertia of the upper flange.

 

Finishing

  • full fabrication of columns, roof girders and corner frames
  • Angelina™ and ACB® which are an economic option for large spans
  • surface treatment – corrosion and / or fire protection

Composite structures for car parks

In the construction of multi-storey car parks, economical and optimisation approaches prevail.

 

Odyseum circe car park in Montpellier, France

 Géric car park in Thionville, France

Steel construction makes it possible to:

  • reduce construction cost
  • optimize car park occupation
  • improve return on investment by gaining floor area

The design of the façade is used by the architect to make the building fit perfectly in the urban landscape. The use of oblique strips, inclined panels, glazed or perforated units etc. help to break the simplicity of prefabricated buildings.

Finishing

  • cutting to exact length
  • cambering along strong axis
  • drilling on the web and flanges of beams to ensure connections
  • assembling and welding of connections plates
  • welding of shear studs connectors
  • Angelina™ and ACB® are an interesting alternative to full web beams
  • corrosion protection, often realized by hot-dip galvanizing

Foundation applications

 

In the frame of geotechnical structures, we are mainly active for the finishing of H-sections for three different applications:

H-pile structures

The steel sections are driven directly into the soil. The pile head is prepared to ensure a better driveability and penetration capacity.The loads are transmitted from the steel sections directly to the soil.

Encased profile composite piles

A steel section is handled in a pre-excavated hole, which is afterwards filled with reinforced concrete. Such composite pile sections allows for very high load-bearing capacity. The loads applied on the head of the steel column are transmitted to the reinforced concrete which is in direct contact with the soil.

Soldier pile / Berliner retaining wall

Consisting of wooden or concrete shield elements lying on vertical H-profiles vibro-driven in the soil, the load is transferred by the steel section directly into the soil.

Finishing

  • cut-to exact length and splice preparation
  • drillings and eventual shear stud application
  • assembling of beams into couples in the case of heavy king piles
  • pile end preparation for improving driveability / penetration / load-bearing capacity
