Steel has high strength and high modulus of elasticity. Compared to concrete and wood, the ratio of density to yield strength of steel structures is relatively low. Therefore, under the same stress conditions, steel structures have smaller cross-sections, lighter self weights, and are easy to transport and install. They are suitable for structures with larger spans, higher heights, and heavier loads.

The colored galvanized steel tiles laid on the roof are the most representative part of the building, both beautiful and durable. Under normal circumstances, the service life can exceed 30 years, and maintenance is free within 20 years.

At present, the instability incidents that have emerged in steel structures are all due to the designer's excessive experience, insufficient clarity on the stability function of the structure and components, and a lack of understanding of the concept of how to ensure structural stability, forming a strong link that should not be included in normal structural design.

If a steel structure canopy is used as an eaves canopy, it can not only serve as a place for shade and rain protection, but also as a larger area ..
