1. Corrosion resistance: the stainless steel ceiling is made of stainless steel, which has good corrosion resistance and will not rust even if it is exposed to harsh environment for a long time. However, tin covers are susceptible to oxidation and corrosion. Rusting will not only affect the appearance, but also affect the stability and safety of the structure.
2. Wind pressure resistance: Compared with iron awnings, stainless steel awnings are more firm and stable, can withstand greater wind pressure, and are not easy to be blown down or damaged by the wind. However, the iron canopy can only bear small wind pressure, and the wind is too strong to cause safety problems such as collapse.
3. Rainwater drainage: The design of stainless steel canopy is more reasonable, which can conveniently collect and adjust the flow direction of rainwater without causing water accumulation and dripping. However, the design of iron canopy is often simple, which is prone to poor drainage, leading to problems such as water accumulation and backward flow, which affects the use and safety.
To sum up, stainless steel awning is safer than iron awning because of its material advantages and structural advantages. Although the price of stainless steel canopy is relatively high, its safety, durability and aesthetics are more prominent, and it is more suitable for long-term use as a building appearance protection device.
