We purchased single slot stainless steel grooved tubes for our glass balustrade projects. WinscoMetal’s slotted pipes have precise groove dimensions, the surface finish is uniform, and all cuts are clean. 201 & 304 material quality is consistent. Our glass panels fit perfectly without extra adjustment. The team was responsive to custom shape requests. Reliable partner for our glass railing business.
