Hot-Dip Galvanized Greenhouse Pipe

Tianjin Juming Steel Pipe Co., Ltd. supplies Hot-Dip Galvanized Greenhouse Pipe for agricultural structures requiring steel framing and corrosion protection. Available in Q195 and Q235B steel grades, the pipes combine a welded steel tube structure with a zinc coating to protect the underlying steel from environmental exposure.

Standard dimensions include outer diameters from 20 to 60 mm and wall thicknesses from 1.2 to 2.5 mm. The standard pipe length is 6 m, with 9 m and 12 m lengths available. These dimensions support the fabrication of greenhouse arches, columns, cross-members, and other structural components.

Custom cutting, punching, bending, and swaging services allow the pipe sections to be processed for different frame layouts. Material grade, diameter, wall thickness, and coating thickness are the main specifications for selecting greenhouse pipe for a particular structure.

01Product Specifications

02Hot-Dip Galvanizing Process

Hot-dip galvanizing applies a zinc coating to the steel surface by immersing the steel component in molten zinc. The process forms a metallurgical bond between the zinc coating and the steel substrate, providing a barrier against moisture and oxygen while allowing the zinc to offer sacrificial corrosion protection where the coating is locally damaged.

For greenhouse pipe, coating thickness is an important factor in assessing corrosion protection and expected service life. Tianjin Juming Steel Pipe Co., Ltd. specifies an average zinc coating thickness of at least 80 μm and a local minimum of 60 μm for the product described here.

Actual corrosion performance depends on coating uniformity, surface condition, humidity, fertilizer and pesticide exposure, coastal salt exposure, and maintenance conditions. The specified coating thickness provides a measurable procurement parameter for comparing products and quality documentation.
