Architectural Metal Gratings & Ornamental Steel

Distinctive Design and Structural Integrity

The clean, elegant patterns of Emmegi’s electrowelded steel gratings provide a signature aesthetic for contemporary architectural design. Highly versatile and adaptable, these products inspire architects to push the boundaries of vision and imagination.

Emmegi gratings can be precision-cut along straight, diagonal, or circular lines and framed with structural steel bars, transforming them into solid, high-performance panels for modern buildings.

Production range and applications

Emmegi manufactures a diverse selection of steel grating patterns engineered specifically for architectural and industrial applications, including:

Fencing and perimeter security
Parapets, Balustrades and Balconies
Crowd-control barriers
Exterior wall-cladding and facades
Brise-soleil and sunshades
Mechanical plant housing and screen walls
Parking structure facades and security screens
Ventilation grilles and decorative enclosures

Versatile Grating Panels & Customisation

Raw grating mats are produced by Emmegi in lengths up to 6,100 mm (approx. 20 ft), 2 meter wide (nearly 7 feet) They are available in:

Mill finish (raw self-color) for secondary fabrication and custom finishing.
Cut-to-size, framed, finished panels, delivered ready for immediate installation.

To ensure optimal installation and structural longevity, please follow these fabrication guidelines:

Cutting: Gratings with flat bars up to 3 mm thick can be easily cut using standard hand tools. We recommend tack-welding a flat bar onto the mat in 2 to 3 superficial points to serve as a cutting guide (these welds should be minimal for easy removal post-cutting). Heavier gratings require plasma cutting or appropriate mechanical machinery.
Framing: Use a flat bar of equal or greater thickness to the bearing bar for the perimeter frame. Weld the frame bar to every connection point on at least one side of the panel. Heavy-duty welds should be applied at all four corners to maximize structural rigidity. For circular frames, a 3 mm flat bar is recommended.

Welding Best Practices: To prevent warping or bowing, weld the frames while the panel rests flat on a sturdy workbench rather than on isolated stands.
Anchoring: Framing bars can be bent and drilled/punched at both ends to create secure anchoring points. Ensure anchor holes have a diameter 2 to 4 mm larger than the fastening bolt. If the supporting structure features a slotted hole, the panel should feature a round hole, and vice versa.
