When manufacturing sliding outdoor canopies, the critical bending moment formula for the overall stability of steel beams reveals that the factors affecting the canopy's critical bending moment include:

The smaller the lateral support length of the canopy beam or the distance between the lateral support points of the compressed flange, the better the overall stability and the higher the critical bending moment.

2. The larger the cross-sectional dimensions of the sliding canopy beam, including all inertial distances, the better the overall stability of the beam. This is particularly true as the width of the beam's compressed flange increases, which can significantly enhance the beam's overall stability.

3. The beam end support constrains the cross-section. If the support can provide rotational restraint on the cross-section axis, the overall stability of the beam can be significantly enhanced. If the bearing can provide rotational restraint on the X-axis, it can also increase the critical bending moment.

4. Load types on the sliding canopy girder. Assuming the ends of the girder are simply supported, the loads act at the shear center of the cross-section.

Firstly, from the perspective of data selection, there are many types of canopy data available, each with its unique characteristics. For instance, using tempered glass offers high light transmittance, allowing for better conditions beneath the canopy even with a pot in place. Additionally, if established through PC data, the entire canopy cover can possess excellent corrosion resistance, making it less susceptible to damage from acidic substances.

In selecting methods, it should also be stopped based on different needs. There are three options: one is cliff-like, with a smaller canopy usually. If there's a high demand for rain shelters, then it's time to opt for better-structured alternatives, such as using sheds with pillars, which offer enhanced support and can withstand stronger external forces while remaining intact.
