From heavy composite decking sheets and thermal thermal-break flashings to walk-in cold storage envelopes, explore certified industrial building solutions manufactured to strict European technical specifications.
The construction sector across Flanders, Wallonia, and the Brussels-Capital Region is experiencing a transformative structural shift. Driven by rapid expansion across the logistics corridors linking the Port of Antwerp-Bruges to the Rhine-Ruhr industrial belt, developers and general contractors (hoofdaannemers) increasingly abandon conventional precast hollow-core concrete slabs in favor of lightweight composite metal decking sheets (staal-beton samengestelde vloeren).
Under Belgian national annexes to Eurocode 4 (NBN EN 1994-1-1), metal decking serves a dual structural function: acting initially as permanent formwork capable of supporting wet concrete, site workers, and equipment without intermediate propping, and subsequently functioning as tensile positive reinforcement once the concrete cures. This composite synergy slashes floor slab self-weight by up to 35%, decreases foundation loads in soft coastal polder soils, and accelerates multi-storey structural erection schedules by over 40%.
However, procuring metal decking in Belgium presents unique engineering complexities. Atmospheric corrosivity near coastal industrial zones (Zeebrugge, Ghent, Antwerp) demands stringent zinc alloy coatings (such as ZM310 or Z275 according to EN 10346), while the federal Belgian Fire Safety Norms (Koninklijk Besluit / Arrêté Royal) impose rigorous REI 60 to REI 120 integrity and insulation criteria without supplementary spray-applied fireproofing.
An objective comparative benchmark assessing manufacturing capacity, European certification standards (EN 1090-1 / EN 10346), roll-forming tolerances, and logistics agility into Belgian building sites.
Operating high-speed automated continuous roll-forming lines capable of over 10,000 m² daily, Emaar Industries delivers an agile, cost-engineered alternative for tier-1 Belgian contractors. Backed by full EN 1090-1 Execution Class EXC3 certifications, mill test certificates (EN 10204 3.1), and tailor-cut lengths up to 15 meters, Emaar eliminates jobsite scrap. Consolidated ocean freight directly into Antwerp or Zeebrugge paired with secondary cold-rolled C/Z purlins and thermal envelope panels gives procurement teams complete supply chain integrity.
The incumbent powerhouse within Belgium, ArcelorMittal produces domestic composite steel floor systems from plants in Geel and downstream facilities in Liège. Known for proprietary dovetail embossments providing high mechanical shear grip, their profiles integrate smoothly with Benor-certified ready-mix concrete networks across Flanders and Wallonia.
Tata Steel's SAB-profiel supplies a significant portion of northern Belgian distribution center roofs.

In-depth answers addressing structural calculations, anti-corrosion specifications, port logistics, and local building approvals.
Re-entrant profiles (e.g., 50mm depth) have a dove-tailed rib geometry providing exceptional mechanical keying and flat underside soffits with dovetail hanging channels, making them ideal for multi-storey residential and commercial office buildings. Trapezoidal profiles (60mm, 80mm, or deeper) provide higher section modulus and inertia, permitting significantly longer unpropped spans required in logistics distribution centers, data centers, and multi-storey industrial car parks.
Yes. Under the European CPR 305/2011, structural cold-formed steel decking sheets carrying harmonized EN 1090-1 CE marking and backed by a comprehensive Declaration of Performance (DoP) and 3.1 mill test certificates are legally equivalent and accepted by Belgian control bureaus (e.g., SECO, Vinçotte, BCCA). BENOR marks primarily govern domestic ready-mix concrete, whereas structural steel requires certified Factory Production Control to EN 1090 EXC2 or EXC3.
Projects within 20 km of the Belgian coastline or near heavy chemical refining clusters in the Port of Antwerp are classified under Corrosivity Category C4 or C5-M according to ISO 12944. For exposed roof decks, standard Z275 (275 g/m² zinc) is often upgraded to Zinc-Magnesium (ZM310) coatings or pre-painted with 50-micron polyurethanes (e.g., Granite HDX) to prevent early edge creep and red rust corrosion.
Yes. By engineering the slab according to NBN EN 1994-1-2 (structural fire design), fire ratings from REI 60 up to REI 120 can be achieved without spray-on intumescent materials. This is accomplished by calculating minimum slab depths (e.g., 120mm to 150mm) and placing single bar reinforcement inside the profile troughs to carry tension during fire exposure once the bottom steel sheet exceeds critical temperatures.
Through-deck stud welding utilizes drawn arc welding guns with ceramic ferrules, fusing 19mm diameter Nelson-type shear studs directly through the galvanized metal deck into the structural steel beam flanges below. This ensures composite beam action in accordance with NBN EN 1994-1-1. For decks with heavy galvanizing (>Z275), pre-punched holes or tailored weld settings are strictly verified during on-site bend-testing (15-degree bend tests).
Direct ocean freight transit to the Port of Antwerp or Zeebrugge generally ranges between 18 to 28 days depending on the dispatch port. Because our automated mills run continuous shifts producing 10,000 m² daily, production turnaround typically takes 7–10 days. Total delivery cycles from technical drawing approval to jobsite arrival in Flanders or Wallonia average 4 to 6 weeks, providing substantial cost savings on large logistics and commercial projects.
In Belgium, the TOTEM tool calculates the environmental impact of building elements. Metal decking scores exceptionally high due to the high scrap recovery rate of steel (over 95%), demountable construction capability, and significant reduction in concrete volume and aggregate consumption compared to solid in-situ slabs. Certified Environmental Product Declarations (EPDs) are provided for direct credit submission.
For 60mm trapezoidal deck in 1.00mm gauge with a 150mm total slab depth, unpropped spans up to 3.80m are achievable under single-span conditions, or up to 4.20m across continuous double-span layouts. For 80mm deep profiles in 1.20mm gauge with 180mm–200mm slabs, clear spans exceed 4.80m without temporary shoring, drastically freeing ground-floor workspace during construction.
