In order to give full play to the advantages of plastic steel doors and windows, and extend the service life of plastic steel doors and windows, in the course of use, attention should also be paid to the maintenance and maintenance of plastic steel doors and windows:
1. The dust on the doors and windows should be cleaned regularly to keep the doors, windows, glass and hardware clean and bright.
2. If the door and window are contaminated with oil stains and other difficult to clean things, you can use Jieer Liang to scrub, and it is best not to use strong acid or strong alkali solution for cleaning, which will not only damage the surface finish of the profile, but also damage the surface of the hardware. The protective film and the oxide layer cause corrosion of the hardware, especially when some customers use the sulfuric acid to clean the wall surface, be careful not to let the doors and windows be infected.
3. The granules and other debris on the inside of the frame should be cleaned in time to prevent the drainage channel from being blocked and causing poor drainage and water leakage.
4. When opening the door and window, the intensity should be moderate, try to keep the speed even when opening and closing.
5. Try to avoid hitting the door or window with a hard object or scratching the surface of the profile.
6. When it is found that the door and window have inflexibility or other abnormal conditions during use, you should find the reason in time. If the customer can't eliminate the fault, you can contact the door and window manufacturer and supplier so that the fault can be eliminated in time.
Safety nets are protective nets installed under or on the side of high-altitude building construction equipment installation or technical performance to prevent accidents caused by falling people or objects. The safety net consists of a net body, side ropes, tethers and tendons. The mesh body is braided with net rope and has diamond or square mesh. Mesh size refers to the distance between two knots adjacent to the knit. The net ropes on the edges around the net body are called side ropes. The size of the safety net (nominal size) is determined by the size of the side rope; the rope that secures the safety net to the support is called a tether. In addition, any rope used to increase the strength of a safety net is collectively referred to as a tendon.

In addition, any rope used to increase the strength of a safety net is collectively referred to as a tendon. The safety net material requires small specific gravity, high strength, good abrasion resistance, large elongation and strong durability. In addition, it should have a certain weather resistance, and its strength does not decrease too much after being wet and wet. Safety nets use chemical fibers as the main material. All net ropes on the same safety net must use the same material, and the wet-dry strength ratio of all materials must not be less than 75%. Generally, synthetic chemical fibers such as vinylon and nylon are mostly used as net ropes. Polypropylene is forbidden due to its unstable performance. In addition, as long as it meets the requirements of relevant international regulations, cotton, linen, palm and other plant materials can also be used as raw materials. No matter what material is used, the weight of each safety flat net should generally not exceed 15kg, and it must be able to withstand 800N impact.
