CPV Code 4545 – Metal Construction
What does CPV code 4545 cover?
CPV code 4545 (Metal construction) covers a broad spectrum of structural and architectural metalwork in steel, aluminium and stainless steel. This includes steel structures (steel frame buildings, hall frames, roof structures, composite construction), railings and balustrades (staircase, balcony and bridge railings), steel doors and gates (fire doors, smoke doors, industrial doors, roller shutters), canopies and metal staircase and walkway structures.
Metal construction combines structural design, workshop fabrication and on-site assembly. Modern metal construction firms work with 3D CAD/CAM systems and CNC machining centres.
Who uses this CPV code?
Metal construction works are found in virtually every building project: building construction (steel structures for roof frames, stairwells, composite floors), infrastructure (steel bridges, pedestrian bridges, railings), schools (railings, canopies, bicycle shelters), sports and event halls (steel hall construction, grandstand structures) and industrial buildings (steel halls, walkways, platforms).
Bidders include metal construction companies, steel fabricators, locksmiths and specialised stainless steel processors, ranging from local workshops to large-scale steel construction firms with in-house design departments and EN 1090 certified workshops.
How does Patterno help?
Patterno HIT filters metal construction tenders by service type and region. The AI distinguishes between steel structures, locksmith works, fire doors and facade substructures, ensuring each company receives only matching tenders.
Patterno BID supports calculation of metal construction specifications — steel weights, surface treatment, assembly and ancillary services — enabling fast and precise bid preparation.
Standards and certification
EN 1090 has significantly tightened requirements for metal construction firms. Companies must establish factory production control certified by a notified body. The execution class (EXC1 to EXC4) determines the scope of quality assurance. Many public tenders require at least EXC2 or EXC3.
