When talking about the fabrication of steel structures, it is common to confuse civil metalwork with high-complexity industrial metalwork. While the former deals with gates, handrails and simple residential structures, industrial metalwork requires a much higher level of precision, document control and mechanical engineering to withstand high dynamic loads.
The Importance of EN 1090 Certification in Metalworking
For a metalworking supplier to execute public works, bridges or large industrial buildings, they must be certified under the harmonized standard EN 1090-1. This CE marking ensures that materials have full traceability, welding is inspected by non-destructive testing (NDT), and the company follows strict execution procedures.
If your industrial project requires the fabrication of lifting gantry systems, suspended industrial platforms or large-span hangars, it is vital to ensure that the partner holds qualifications in the appropriate execution class (EXC2 or EXC3).
Quality Control and Certified Welding
Welding is the heart of any complex steel structure. In high-complexity metalwork, welders and welding operators must hold updated certifications (ISO 9606). Each welded joint follows a specific WPS (Welding Procedure Specification) plan supported by WPQR (Welding Procedure Qualification Record).
At Lopes & Caldas Engineering, we ensure that all these technical compliance requirements are strictly monitored by our quality department, minimizing any structural risk at the installation site.
Conclusion
Choosing the right manufacturer depends directly on the level of demand of your construction. For industrial applications where failure is not an option, certified metalwork is the only safe way. Count on Lopes & Caldas Engineering as a reliable strategic partner.
