פשוט עיצוב זכוכית צעד ספירלת מדרגות מודרני מקורה עץ לדרוך סליל מדרגות

This project is dedicated to designing customized staircase products for townhouses. Indoors, we have opted for stringer staircases with tiled tread surfaces, placing stringent demands on both the staircase's structural design and error control. Outdoors, spiral staircases are installed, featuring a premium and elegant look achieved through black spray-painted surface treatment.
