Steel hollow sections for every kind of project

A truss in a logistics hall, the frame of a special-purpose machine, the arch of a footbridge, the boom of an agricultural implement: the same rectangular section can end up in all of them, and every one of them asks something different of it. Static or dynamic loading, welded or galvanised, exposed or hidden, ordered by the tonne or cut to the millimetre.

That is why we start from the project rather than from the stock list. What does the component have to carry, what will it be welded to, what happens to its surface afterwards, and when does it have to be on site.

How we support your project

The same three questions come up in every enquiry. What changes from one project type to the next is the answer.

Selecting the section

Hot-finished or cold-formed, which grade, which dimension. The load case decides, and we work through it with you before the order is placed.

Steel Trading products

Processing before delivery

3D tube laser cutting, cuts to length, mitre cuts, bending and blasting. Material can arrive ready to assemble instead of ready to prepare.

Getting it to site

A broad stock range, access to special products and a connected logistics network across our markets keep delivery times short and predictable.

Machine Construction

Machine frames, bases and gantries are welded assemblies that have to stay dimensionally true through milling, drilling and welding, then hold their geometry under loads that change direction thousands of times a day. Batch sizes are small, repeat orders are common, and tolerances are tight.

What matters here

  • Hot-finished sections for constantly alternating loads
  • Low residual stress, so machining does not distort the part
  • Laser cut positioning and assembly aids for repeatable frames
  • Lifting, handling and construction equipment with the same requirement profile
  • Ordering from 3D data in STEP, IGES, IFC, DWG or DXF

Plant & Steel Construction

Columns, trusses, frames and roof structures in hall construction, supporting frames, platforms and walkways in plant projects: this is where cold-formed hollow sections are used most. Flat faces and narrow visible widths make the node connections manageable, and because a structure repeats the same detail many times over, cutting accuracy turns into a cost factor rather than a detail.

WHAT MATTERS HERE

  • Cold-formed sections to EN 10219 for columns, trusses and frames
  • Node geometry that can be welded without rework on site
  • Platforms, walkways and access structures in plant projects
  • Cutting lists, fixed lengths and mitre cuts prepared in advance
  • Deliveries phased to the erection or assembly programme

bridge_construction

Bridge Construction

Bridges carry loads that never stop changing, in weather that never stops working on the structure. That combination puts the emphasis on material behaviour rather than on dimension alone, and it usually brings curved members into the design.

WHAT MATTERS HERE

  • Hot-finished sections to EN 10210 where dynamic loading is expected
  • Uniform grain structure across the full cross section for demanding welds
  • Bent and rolled members for arches, ramps and railings
  • Higher strength grades such as S355NH, S420NH and S460NH
  • Grades and dimensions agreed with the design team at an early stage

vehicle_construction

Vehicle Construction

Chassis frames, superstructures and trailer components are built in series, which means every length has to behave like the one before it. Weight and strength pull in opposite directions, and the welded frame has to absorb impact without losing its geometry.

WHAT MATTERS HERE

  • Hot-finished sections for dynamically loaded frames
  • Consistent properties from delivery to delivery in series production
  • Ductility and energy absorption under impact loading
  • Laser cut contours and openings ready for assembly
  • Fixed length cuts that avoid costly offcuts in the workshop

Elevators & Cable Ways

Cable car supports and elevator structures work under alternating loads, in exposed locations, often at altitude and at low temperatures. Installation windows are short, access is difficult, and the structure has to remain inspectable for decades.

WHAT MATTERS HERE

  • Hot-finished sections for continuously alternating loading
  • Material behaviour at low temperatures in exposed locations
  • Weldability and suitability for hot dip galvanising
  • Long members processed in one piece, up to 14 m on the tube laser
  • Delivery planning for sites with restricted access

Agriculture Machine

Agriculture Engineering

Implements, trailers and booms are loaded in shocks rather than in steady cycles, then left standing in mud, moisture and fertiliser. Repairs happen in the field with a welding set, so the material has to forgive as much as it carries.

WHAT MATTERS HERE

  • Shock and dynamic loading in everyday operation
  • Welded joints that can be repaired outside the workshop
  • Sections sized for weight critical implements and booms
  • Repeatable cutting for series production
  • Standard grades held in stock for short lead times

Ship Building

Structures on and around the water live with salt, humidity and permanent movement. Weld quality and corrosion protection decide how long a component lasts, and material requirements are usually defined project by project rather than by a catalogue.

WHAT MATTERS HERE

  • Corrosion loading from salt water and constant humidity
  • Weld quality in permanently loaded structures
  • Grades and any required certification clarified project by project
  • Blasting as preparation for protective coating systems
  • Large dimensions and long lengths from one supplier

Metal Construction

Where the structure stays in view, the section is part of the architecture. Substructures for glass facades and glass roofs, staircases, balustrades, canopies and gates are judged on sightlines as much as on load capacity, and elliptical or semi-oval sections open up shapes that round tubes cannot.

WHAT MATTERS HERE

  • Elliptical, oval and semi-oval sections for exposed structures
  • Narrow visible widths and clean welded junctions
  • Substructures for glass facades and glass roofing
  • Bent members for staircases, balustrades and curved frames
  • Interfaces with the aluminium and steel systems on the architectural side

Hot-finished or cold-formed

Most enquiries come down to this one decision, and it is rarely a question of price. Both types are held in stock, and the load case usually points clearly to one of them.

Hot-finished to EN 10210

Formed at normalising temperature, which gives a uniform grain structure and hardness across the whole cross section. Small corner radii mean a larger cross sectional area, higher section properties and a higher buckling curve.

Cold-formed to EN 10219

The usual choice in structural steelwork, metal fabrication and plant engineering. Straight faces, narrow visible widths and sound node connections make structures quick to fabricate and efficient in use of space.

Welding and galvanising

Hot-finished sections have no hardening in the corner regions, a common cause of cracking, so they can be welded and hot dip galvanised without special precautions. Their low residual stress also keeps parts stable during machining.

Grades and dimensions

S235JRH, S275J2H, S355J2H, S355NH, S420NH and S460NH, plus stainless steel and special grades on request. Square sections from 15 x 15 mm, rectangular sections from 15 x 10 mm upwards.

Who We Work With

Two groups shape every delivery: the mills that roll the material, and the workshops that turn it into a structure.

Steel producers

The European mills behind our range. Long term supply relationships give us access to the grades, dimensions and special products our markets ask for, and a direct route back to the works when a project needs something outside the standard programme.

Processing before it reaches you

Every step we take before delivery is one your workshop does not have to repeat. Fewer operations, better weld preparation and no offcuts left over from cutting in house.

  • 3D tube laser cutting of hollow, open and oval sections
  • Fixed length cuts, single and double mitre cuts
  • Cold and hot bending, rolling and press bending through our bending partners
  • Sandblasting to remove rust, scale, soiling or old coatings
