The greenhouse is constructed using hot-dip galvanized frames, which ensures its strength continues to increase over time. Consequently, there are specific requirements for its anti-corrosion process during assembly to enhance the protective strength level.

Another consideration for the breeding shed is the issue of insulation. Generally, the roof of large buildings is a surface with significant heat loss, and during summer, it also contributes to the increase of indoor temperature. Therefore, insulation for the roof is necessary.

The foam produced by polyurethane spraying is independently sealed, offering relatively good insulation properties. Due to the independent pores of the foam, it also has a certain vapor barrier effect.

Polyurethane's application in animal sheds effectively addresses both vapor barriers and insulation, reducing the corrosion caused by steam from the breeding wastewater on the roof, significantly extending the service life of steel structures. Due to its excellent insulation properties, it ensures that the sheds remain warm in winter and cool in summer, demonstrating remarkable energy-saving and emission-reduction effects.
