Belgium Formwork
A structure designed to last
The project involved the design, manufacturing and delivery of a complete metal structure for an industrial production unit in Lyon, France. The project required a rigorous technical approach, with special attention to operational loads and the seismic requirements of the area.
SCARSMETAL managed the entire process — from technical study and structural sizing to workshop manufacturing and shipping. The structure includes a main hall, secondary structures, metal roofing and access mezzanines.
The delivery deadline of 14 weeks, considered challenging for the scale of the project, was strictly met thanks to industrial organization and quality control implemented at each production stage.
All elements were manufactured according to EN 1090-2 standard, with complete raw material traceability and a technical dossier delivered with the project.
Technical challenges overcome
Each project brings specific constraints. These were the main challenges of this work.
28-meter spans
The main hall required roof trusses with 28m clear spans, optimized to minimize weight while maintaining the structural stiffness required by Eurocode 3.
Seismic zone Z3
The site location requires Z3 seismic compliance. The structure was designed with specific bracing and energy dissipating connections.
14-week deadline
The client's production startup was conditional on the deadline. We organized production in parallel by zones to ensure strict compliance.
20t crane load
The main hall integrates a 20-ton overhead crane. Brackets and rails were dimensioned with ±1mm tolerances over 80 linear meters.
C4 corrosion protection
Aggressive industrial environment required hot-dip galvanizing + duplex paint system, with 25-year protection guarantee according to EN ISO 12944.
Workshop pre-assembly
The 3 halls were pre-assembled in the workshop for complete geometric validation before shipping, eliminating the risk of on-site errors 1200km from the factory.
Detailed specifications
The execution process
From the first technical meeting to final delivery on site.
Technical Study & Design
Analysis of plans, load assessment and definition of the structural solution. Technical validation with the client and issuance of initial execution plans.
3D Modeling & Drawings
Complete modeling in specialized software. Production of detailed manufacturing drawings with dimensions, part lists and welding schematics.
Workshop Manufacturing
Laser cutting, bending, welding and progressive assembly. Dimensional control at each stage. Application of corrosion protection under controlled conditions.
Pre-assembly & QC Control
Dry assembly of the 3 halls in workshop. Complete geometric control. Quality dossier with certificates, welding reports and dimensional control.
Treatment & Painting
Hot-dip galvanizing and duplex painting according to C4 specification. Curing in controlled chamber. 100% visual inspection and film thickness control.
Shipping & Delivery
Optimized loading on special trucks. Coordinated delivery with client's assembly team. Delivery of complete technical dossier.
