Product Introduction

arrow_bom

Structure Steel Tube Column is a flexible and adaptable furniture design that brings many practical advantages to home and office environments. The furniture column tubes produced by CBIES have high strength and smooth straightness, ensuring stable support for the table and chair structure and flexible size adjustment. Precision processing ensures that the steel tube is accurate in size and has a smooth surface without burrs, making it smooth to operate and ensuring that it will not deform after long-term use, providing users with a safe, reliable and comfortable use experience.
