Galvanized Circular Tube Lattice Column: Superior Strength and Durability for Your Projects
Shenyang Zhongda Steel Structure Engineering Co., Ltd. is a leading manufacturer and supplier of Galvanized Circular Tube Lattice Columns. Our advanced manufacturing capabilities, rigorous quality control, and innovative design solutions set us apart in the industry. Zhongda's products offer unparalleled strength, corrosion resistance, and versatility for your telecommunication, power transmission, and infrastructure projects.
Product Description
Our products are engineered to meet the highest industry standards, providing exceptional structural integrity and longevity. These columns are fabricated using premium-grade ASTM A500 seamless steel pipes with diameters ranging from 114mm to 508mm and wall thicknesses of 5-30mm. The lattice structure incorporates round steel or steel pipe bracing, optimizing strength-to-weight ratio and wind load resistance. Our columns undergo a hot-dip galvanization process, ensuring superior corrosion protection even in harsh environments. This makes them ideal for coastal areas, chemical plants, and other challenging locations. With a compressive strength of ≥345MPa, these columns are built to withstand extreme conditions and provide long-lasting performance.
