01/ 06
Materials sourced from quarries worldwide, fabricated in Dallas, and installed by Sigma field crews across both states.
From slab selection in the quarry to the final polish on site, one team carries the material through drafting, fabrication, and field installation. That is how suites at national stadiums, terminal floors, and opera house staircases stay flawless under millions of footsteps.
