Galvanized Greenhouse Frame Structure is a complete agricultural framework designed to provide stable support for greenhouse coverings, crops, and farming equipment. Built with corrosion-resistant galvanized steel components, it delivers reliable structural strength, weather resistance, and long-term performance for modern agricultural facilities.

Galvanized Greenhouse Steel Pipe is a durable structural material designed for modern agricultural greenhouse construction. Made from high-quality carbon steel with hot dip galvanizing protection, it offers reliable strength, weather resistance, and long service life for vegetable greenhouses, flower cultivation facilities, nurseries, and agricultural structures.

Hot Dip Galvanized Oval Steel Pipe is a durable welded steel tube featuring an oval cross-section and corrosion-resistant zinc coating. Manufactured from carbon steel with precision forming and hot dip galvanizing technology, it provides strong structural performance, lightweight construction, and an attractive appearance for agricultural, architectural, furniture, and industrial applications.

ZHONGTIAN Small Diameter Hot Dip Galvanized Oval Steel Pipe is a lightweight and corrosion-resistant steel tube designed for compact structures, outdoor applications, and decorative projects. Manufactured through cold forming, welding, and hot dip galvanizing processes, it offers excellent durability, stable performance, and flexible customization options for various industries.

ZHONGTIAN Large Diameter Black Rectangular and Square Steel Tube is a heavy-duty hollow steel profile, typically defined as a large-section tube with a side length ≥ 100mm. It is manufactured using Q235B or Q355B carbon steel through high-frequency welding, submerged arc welding, or seamless forming processes. The product boasts core advantages such as large cross-section, high load-bearing capacity, and excellent bending and deformation resistance. The surface is a natural black oxide scale, without galvanizing or painting, providing a cost-effective structural support solution for heavy steel structures, industrial buildings, and large-scale infrastructure.

ZHONGTIAN Thin Wall Black Rectangular and Square Steel Tube is a lightweight hollow profile made from carbon steel strip through high-frequency welding. The surface has a natural black oxide scale, without galvanizing or coating treatment, making it a cost-effective solution for light-load structures. The material is typically Q235B, which is lightweight, easy to cut, easy to weld, easy to bend, and convenient for secondary processing. It is widely used in light-duty frames and decorative structures where load-bearing requirements are not high.
