Since opening its doors in 2009, Brooklyn-based MetalMania Sheet Metal Works has built custom metalwork for architectural, commercial, and residential spaces. Its projects are made in-house by skilled fabricators, including a lead metalworker with more than 30 years in the trade and earlier experience reconstructing casinos in Macau, China. The shop is known for turning detailed designs into precise pieces, from curved stainless-steel handrails to blackened-steel staircases.
