How to Read European Material Specs Like a Pro

Working with European materials can open up an entire world of design possibilities — but for many builders and architects, the technical documents that accompany those products can feel like a foreign language.

Metric dimensions, unfamiliar standards, and nuanced finish descriptions can make it difficult to compare or specify products accurately.

At Gabriel Immo Supply, we help bridge that gap. Here’s a simple guide to understanding European specification sheets — so you can read them confidently and make informed choices on every project.

1️⃣ Know the Measurement Conversions

Most European spec sheets use the metric system, which can cause confusion if you’re accustomed to inches and feet.

Quick reference:

You’ll typically see thicknesses in millimeters (e.g., “20mm slab”) and tile sizes in centimeters (e.g., “60x120cm,” which equals roughly 24x48 inches).

Pro Tip: When in doubt, visualize 30cm as roughly 1 foot — it’s an easy way to estimate during early design stages.

2️⃣ Understand the Standards and Classifications

European materials often reference technical standards that differ from U.S. codes but are just as rigorous — sometimes even more so.

Common European standards include:

• EN 14411 — Ceramic tile classification (similar to ASTM C373 in the U.S.)

• EN 14617 — Agglomerated stone performance standards.

• EN 12440 — Natural stone denomination and quarry origin.

• CE Marking — Indicates compliance with European health, safety, and environmental requirements.

If you see “EN” followed by a number, that’s a European Norm — essentially the EU’s version of an ASTM or ANSI test.

Pro Tip: Look for CE markings and EN certifications as indicators of quality and traceability.

3️⃣ Decoding Finish Terms

Finishes can be another point of confusion. European suppliers use descriptive terminology that may differ from U.S. counterparts.

Common finish translations:

Understanding these terms helps ensure you specify exactly what your client expects — and avoid surprises on delivery.

4️⃣ Recognize the Tolerance Language

European specs often indicate allowable tolerances — small variations in dimension or thickness that are part of manufacturing norms.

Example:

“Dimensional tolerance: ±0.5mm”

This means each piece may vary slightly within that range, a standard well within acceptable limits for professional installation. European factories are known for extremely tight tolerances, which is why large-format tiles and slabs from Italy or Spain align so precisely.

5️⃣ Watch for Absorption, Slip, and Strength Ratings

When comparing materials, performance ratings are key.
These indicate how the product will behave under real-world conditions.

Look for metrics such as:

• Water Absorption (%): Lower is better — porcelain is often ≤0.5%.

• Slip Resistance (R Rating): R9–R13 scale for flooring grip (R9 = smooth interior, R13 = textured exterior).

• Flexural Strength (N/mm²): Indicates resistance to breaking under pressure — higher is stronger.

Understanding these numbers helps ensure the right material is placed in the right environment (e.g., R11+ for pool decks, R9 for interiors).

6️⃣ Let GIS Be Your Translator

Even seasoned builders can miss nuances in European documentation.
That’s why Gabriel Immo Supply reviews every spec before procurement — verifying accuracy, finish, and application to ensure your materials perform as intended.

We provide:

• Translated spec summaries for clarity

• Recommendations for U.S. code compatibility

• Guidance on installation requirements and maintenance best practices

Our goal is to make working with European materials as seamless as working with a local distributor — without compromising on quality or design integrity.

Build Confidence in Every Specification

Understanding specs isn’t just about details — it’s about control.
When you know how to read European documentation, you gain confidence, efficiency, and creative freedom.

At Gabriel Immo Supply, we bridge the gap between European precision and American practicality — so your next project runs smoother from start to finish.
