The geometry demands precision at every stage: the center column, the rise and rotation of each tread, the connection points, the railing that follows the curve. At BAMPRO, spiral staircases are fabricated entirely in our Durham shop by metalworkers who have been doing this for over 30 years.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEach spiral is built to the specific dimensions of your space — diameter, rise height, tread count, and handedness. Tread materials can be specified in steel, wood, or a combination of both. Finish options include raw steel, powder coat, and custom patina depending on the application and design intent.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSuited for:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eResidential interiors — primary and secondary stair applications, loft access, rooftop connections\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCommercial and hospitality projects where a focal point staircase is part of the design brief\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRenovation and infill projects with constrained footprints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSpiral staircases are a collaborative build.
