- Bolted and welded connections on site
- Alignment, plumbing and bolt torque verification
- Crane coordination and heavy lift planning
- Method statements, lift plans and safety documentation

Where we work and how we stay compliant
Steel erection crews across Europe — compliant from day one
Metal KLS has delivered projects in nine European countries — Belgium, Denmark, France, Germany, Hungary, Luxembourg, the Netherlands, Romania and Sweden — and is set up to mobilise immediately into twelve. With lead time for registration, we can work anywhere in the EEA.
Posting a workforce across borders is where most subcontract arrangements come unstuck, so we complete registration, documentation and site access before the crew travels.
- Denmark — RUT registration completed before mobilisation
- Sweden — ID06 cards issued and personnel ledger maintained
- Germany — SOKA-BAU registration and minimum wage compliance
- Belgium — Limosa declaration and Check In At Work site registration
- Netherlands — WagwEU notification and A1 certificates for every worker
- All countries — A1 social security certificates, EN ISO 9606-1 welder qualifications and VCA/SCC safety certification
You receive the complete compliance pack before the first crew arrives on site. No chasing paperwork mid-programme, no access refusals at the gate.
How we work
From first enquiry to handover — a straightforward process with no surprises.
Enquiry & Assessment
Send us drawings, tonnage and programme dates. We assess scope, crew size and lift requirements, usually within two working days.
Quote & Planning
A transparent quote setting out crew composition, rates and expected duration. Priced hourly, per tonne or per project — your choice. No hidden costs.
Mobilization
Crews mobilise in 10 business days with PPE, tools and certifications in place. That is our standard lead time — it covers crew allocation, travel, accommodation and country registration.
Execution & Handover
On-site erection with daily progress reporting to your site manager. Clean handover with as-built documentation on completion.
Steel erection team composition
Crews are built around your project — from a two-man team supporting your own erectors to a full self-managing gang of 40.
Steel Erectors
Experienced erectors and steel fitters skilled in bolted assembly. Work-at-height certified, trained in safe rigging and slinger/signaller duties.
Working Foremen
Senior erectors with 5+ years on site. They run the daily work, manage quality checks and liaise directly with your site team in English.
Site Welders
Welders qualified to EN ISO 9606-1 for on-site welded connections. MMA, MIG, MAG and TIG, all positions.
Site Managers / Supervisors
Qualified construction engineers who oversee erection accuracy, handle RFIs and hold the line on design compliance.

Steel erection — common questions
How quickly can you mobilise a steel erection crew?
Ten business days from signed order. That is our standard lead time and covers crew allocation, travel, accommodation and country registration — we don’t promise faster, because doing it properly takes that long.
Do you work as a subcontractor to main contractors?
Yes — most of our work is subcontract erection for main contractors, steel fabricators and specialist installers. We work to your method statements, your programme and your site rules.
Which countries do you operate in?
We have delivered projects in nine: Belgium, Denmark, France, Germany, Hungary, Luxembourg, the Netherlands, Romania and Sweden. We can mobilise immediately into twelve, and anywhere in the EEA with lead time for registration. We handle posting compliance in each — RUT in Denmark, SOKA-BAU in Germany, Limosa in Belgium, ID06 in Sweden.
Do you supply the steel as well as erect it?
Usually not — most of our work is erection only, with the steel supplied by you or your fabricator. We can quote supply and erection as a package on request, but our core service is the crews, supervision and equipment to erect steel that already exists.
What certifications do your crews hold?
VCA/SCC safety certification for all site personnel, EN ISO 9606-1 qualifications for welders, and work-at-height and rigging certification for erectors. The company holds EN 1090, ISO 9001 and ISO 14001. Full documentation is provided before mobilisation.
How is steel erection priced?
Three ways: hourly rates per operative from €39, a rate per tonne erected, or a fixed price for the full package. Which works best depends on how well-defined the scope is at tender stage.
What size projects do you take on?
From two-man crews supporting an existing team through to self-managing gangs of forty on multi-phase programmes. Our largest continuous deployments have run from a few months up to multiple years on data centre and bridge projects.
