What is EN 1090?

The EN 1090 standards are European rules for making and putting together steel and aluminum structures. They are backed by the Construction Products Regulation (CPR). These rules apply to any structural part made and produced to meet the BS EN 1991 series of standards (Eurocode 3 and 9) for steel and aluminum in buildings².

Understanding the EN 1090 Standards

Since July 2014, structural steelwork and aluminum have been under the CPR. This means that aluminum or structural steel CE marking is needed to show they meet EN 1090-1 – the European standard for structural metalwork³. The EN 1090 standards give a detailed guide for making fabrication of structural steel and aluminum. They make sure these materials are safe and work well. By following these standards, makers can make sure their products are good enough for the construction world.

The EN 1090 standards talk about welding, keeping track of materials, testing, and quality control. People making and selling these products must follow these rules to show they’re okay and get the needed papers to sell in Europe. Knowing and following the EN 1090 standards is key for keeping structural steel and aluminum safe and strong.

EN 1090 Uncovered: The Secrets to Structural Steel Requirements

Manufacturers and suppliers of steel and aluminum must follow the EN 1090 standard to get certified and CE mark their products³. They need a strong Factory Production Control (FPC) system. This system checks if steel and aluminum meet the needed standards and rules³. It includes steps, checks, tests, and reviews, and uses these results to manage materials in the design³.

Steel is key in building, making things, and building infrastructure because it’s strong and can last a long time⁴. Weather can make steel rust, especially when it’s exposed to air and moisture⁴. To fight this, people use zinc coating or paint to protect the steel⁴.

BS EN 1090-2 sets the rules for steelwork in building designs that follow Eurocodes⁵. Early Contractor Involvement (ECI) means main and steelwork contractors work together from the start⁵. Things like where the site is, getting to it, what equipment is available, and how it’s done in stages can affect building⁵.

Getting the surface ready right is key to keeping steel from rusting, especially if it’s rough⁴. EN 1090 and EN-ISO 12944 Part 2 say steel sections need a smooth edge before painting to stop rust⁴. A bigger surface for paint and coatings means less chance of peeling and rust⁴.

BS EN 1090-2 is the go-to standard for steelwork in Eurocodes⁵. CDM Regulations stress finding and fixing hazards early to lower risks⁵. Buying steel plates and sections directly from mills saves money⁵.

“Not protecting steel properly can cause paint to flake off and rust, especially at sharp edges.”⁴

Bevelling, or making edges smooth and rounded, is crucial to stop rust and make steel last longer⁴. Machines like the PROMOTECH BM-7, BM-18, and BM-18A make edges smooth to protect against rust⁴. Special beveling machines help keep steel safe from corrosion and make it last longer⁴.

When ordering materials, you need to know about bolt sizes, shear stud sizes, and how things fit together⁵. M24 preloaded bolts are best because they’re easy to use and get⁵. For bridges, 19 mm studs are the top choice for shear connectors⁵. Steelworkers must figure out how much a structure will change over time based on different factors⁵.

Factory Production Control (FPC): The Key to Compliance
