Project overview

Goldbelt Tower II is a prominent commercial high-rise project in Luxembourg. With a height of 115 meters, 29 floors, and around 50,000 m² of office space, the building required an exterior material that could support a modern architectural image while meeting the durability expectations of a large commercial tower.

For this project, LXCC supplied G654 dark grey granite facade slabs for the building exterior. The material was used as part of the facade / curtain wall stone cladding system, giving the tower a refined dark grey appearance and long-term performance for an exposed urban environment.

Why G654 granite was selected for the facade

G654 granite is a well-known dark grey Chinese granite with a fine, uniform texture. It is also commonly known in the stone market as Padang Dark granite or Sesame Black granite. Because of its stable color, dense structure, and good wear resistance, G654 is widely used for exterior walls, facade panels, paving, steps, commercial projects, and public architectural stonework.

For Goldbelt Tower II, the dark grey tone of G654 granite works well with the building’s modern high-rise design. The stone gives the facade a calm and solid visual language, while its compact granite structure helps the exterior surface resist weather exposure, daily wear, and long-term outdoor use.

Custom G654 facade slab production

Facade stone projects require more than attractive material. Each slab must be produced with stable dimensions, controlled thickness, clean edges, and consistent surface finishing. For a high-rise facade, these details affect not only the final appearance but also the efficiency of installation.

Lexiang Stone processed the G654 granite into facade slabs according to project requirements. The production work included material selection, slab cutting, surface finishing, thickness checking, edge finishing, and preparation for export packing.

The project display images show the G654 slabs during production and inspection, including large-format panels, finished edges, thickness checking, and polished dark grey surfaces. These details help show the production control behind the final architectural effect.

Dark grey granite for modern commercial architecture

G654 granite is especially suitable for commercial buildings that need a clean, modern, and professional facade. Compared with lighter stones, dark grey granite creates a stronger architectural outline and pairs well with glass, metal, aluminum panels, and curtain wall systems.

For Goldbelt Tower II, the G654 stone facade contributes to a high-end corporate appearance while keeping the building visually stable and elegant. The material is practical for large-scale projects because it offers a good balance of color consistency, durability, availability, and cost control.
