When building a photovoltaic sun room or photovoltaic roof, what kind of frame structure is more suitable?
Let's talk about this topic today.
I am building a photovoltaic roof behind me. The square tube used is actually called a galvanized square tube.
Why use this square tube?
1. Its biggest feature is high cost performance.
2. Its installation structure is convenient.
3. The overall frame has strong structural strength.
Some people will ask why not use aluminum alloy as the frame? It is not impossible. The biggest problem with the aluminum alloy frame is that the cost is relatively high, and the overall frame strength is not as high as that of the galvanized square tube. However, aluminum alloy also has its characteristics. It has many colors, good appearance, and is more beautiful to build. But although this galvanized square tube is cheap and highly structural, it is not good-looking.
Some people will ask if there is a way to be both cheap and good-looking? That is to color and repaint it after the installation is completed, spray it into the desired color, and match it with the original home decoration style. The overall effect looks like the frame built with aluminum alloy.
New energy vehicle safety components: structural parts are the key
With the booming new energy vehicle industry, safety issues have always been one of the most concerned focuses of consumers, manufacturers and regulators. Compared with traditional fuel vehicles, new energy vehicles have significant differences in power systems, energy management and intelligent control, and these differences have also posed new challenges to the safety performance of vehicles. Among the many safety components, structural parts are the key elements that support and protect vehicles, and their importance is self-evident. This article will explore in depth the key role of new energy vehicle structural parts in safety performance, and how to improve their overall safety through technological innovation and material upgrades.
