Guide for selection of sunshade accessories for lighting roofs

There are more and more glass daylighting roofs in modern buildings, and some shopping malls and hotels are all daylighting roofs, which are magnificent and high-grade! But the problem is that in summer, when the sun is shining directly, the temperature in the top area of the lighting is quite high, which makes it inconvenient to turn on the air conditioner. At this time, the lighting roof becomes a big brazier. Don't even want to get close. Therefore, it appears in the sunshade of the daylighting roof.

Many change gears are made of plastic or very small iron, both of which have short life and are easy to break and deform. Some wheels have bearings inside, which look very slippery, but they are not practical, because the bearings are too small, and the beads on the inner surface are easy to wear and tear when heated for a long time, which eventually leads to immobility. The best is the change wheel based on the principle of automobile steel sleeve. Although there is no bearing sliding, it is not easy to cause problems and has a long service life.

Rope winder

There are two kinds of nylon materials and PVC plastic materials. Nylon is generally a solid material, which is a silk grain from a lathe. PVC is generally hollow and poured out of the mold. Nylon is stronger, more resistant to high temperature and less prone to aging.
