STEP 1: Prepare Actions Turn on the air conditioner for 15 minutes before cleaning the air conditioner so that the air conditioner starts to cool, and at the same time, condensate water is generated in the air conditioner evaporator. After closing the air conditioner, cut off the power to ensure safety. Preparation items: commonly used rags at home, special cleaning agents for air conditioners, soft brushes with soft texture. Ready? Go! 
STEP 2: Cleaning the Air Conditioning Enclosure First, open the air-conditioning cover and gently wipe the exposed enclosure with a wet cloth. Care should be taken in the details and connections to prevent the remnants of dust on dead ends. Note that the left and right sides of the air conditioner and the top position can not be ignored, and there is no need to wipe or press the panel very hard, and it is easy to damage the surface of the shell. Air outlet outlet guide page is also a place that needs to be cleaned. During long-term use, it is easy to accumulate dust on the surface due to the air outlet. If the panel is particularly dirty, it can be wiped gently with a soft cloth moistened with warm water or a mild detergent, and then wiped dry with a soft dry cloth.
STEP 3: Cleaning the Air Conditioning Filter After opening the case, you will see that there are two plastic boxes inside and one on the left and right. This box is to filter air-conditioned air, the most hidden parts of the dirt. Depending on the model, air-conditioning filters are also different. It should be noted that not all filters can be cleaned with clean water, and some need only to remove dust, while others need to be replaced within a certain period of time. If it is determined that it can be cleaned, remove the filter according to the instructions and clean it with tap water. If the filter dust is too much, you can use water to rinse or soft brush to clean the neutral detergent. However, when cleaning, the water temperature should not exceed 50°C. It is better not to use washing powder, detergent, gasoline, banana water, etc. Filter dust network deformation.
STEP 4: Some users of cleaning air conditioner evaporators reflect that the filter is cleaned regularly every month, and the dead angle will be wiped clean. Why is the airway still uncomfortable? In fact, behind the filter, there is an evaporator. This place is easily overlooked by many users. When the air-conditioning is running, the evaporator will produce condensate, so this part is in a state of moisture for a long time, it is easy to adhere to dust, and it is more likely to cause bacteria to multiply. If the dust on the evaporator fins is heavy, it can be removed with a soft brush first. The air-conditioning cleaner is sprayed on the surface of the aluminum heat-transfer sheet and the coils on the evaporator fins, and is generally sold in home appliance stores or supermarkets to ensure that the clean foam completely covers the surface of the evaporator. After about 15 minutes, the air-conditioning cleaner will completely infiltrate the reaction, fully destroy the stubborn dirt on the fins of the air conditioner evaporator, and then wipe it off with a soft cloth.
STEP 5: Close the filter and replace it with the cover of the air conditioner. Then plug in the power supply, turn on the air conditioner, turn the air volume and cooling capacity to the maximum, and keep the air conditioner on for about 20 minutes, so that the dust on the evaporator can be removed and the sewage can be discharged from the drain pipe. The air conditioner is best cleaned 2 to 3 times a year. Normally, the air conditioner is cleaned once before it is turned on, and the air conditioner is cleaned once during the middle period of the boot. When the air conditioner is turned off, it is cleaned once. This is reasonable. Don't be lazy! air conditioning
The steel grating be welded to products . Normally, hot galvanizing will be carried out after end welding process. The range PH6 to PH12.5, a stable protective film will be formed on the zinc surface, the hot dipped galvanized steel grating has good anti-corrosive property. Of course, the steel grating also have other surface treatment, for example painted and powder coated .
Steel grating can be cutting to different kinds of shape as per your special needs.
Steel grating including flat grating, 'I' shape grating, serrated grating.
In generally , the steel grating be used as stair tread, platform, fence, trench cover, ceiling, etc.
The advantage of steel grating :
firm welding
smooth surface
high strength
