Louvers are open classifications of aluminum alloy louvers because of their active branches of grid users. Window models are popular in the market nowadays. They are suitable for push-pull or even some open classifications. Curtain door refers to the closure device around the curtain door facing inward or opening the curtain door; electric curtain door refers to the curtain door along the vertical degree of the curtain door around the curtain door. Push-pull and level under equal conditions everyone has their own advantages in the choice of glass and accessories. The appearance, function, price of the lower door, endurance of hardship and other aspects of detailed and accurate discussion have their own characteristics.
First, function comparison
In the three functions (wind pressure resistance, water tightness, air tightness) of the curtain door, the curtain door is widely superior to the push-pull window. The wind pressure resistance of the curtain door depends on the resistance moment of the main stress bar of the curtain door. The larger the section, the greater the resistance moment, but it can not be proportional in good condition. Generally, the section of roll-curtain doors is small, but the main force poles are composed of composite frames or vertical materials. These main force poles will be strengthened in the planning process, so their wind pressure resistance function is better. The profile of push-pull window is generally large. It is said that its wind pressure resistance should satisfy better theory, but only a little deeper stress analysis is needed to understand that its main stress pole is often fan feed. The direction of wind load for the next elevator depends only on the degree of pulley. The reason is ambition of poor wind pressure resistance in general. The water tightness of the rolling shutter door depends on the sealing effect of the opening part. The rolling shutter door is usually sealed discontinuously by rubber strip, while the pushing window is sealed discontinuously by wool strip. The sealing effect of rubber strip is much better than that of wool strip. In terms of air tightness, the rolling shutter doors are mostly sealed by two-point lock or intermittence lock in the market, and the sealing effect is better. The sliding window generally adopts hook lock or fastening lock intermittent lock, its sealing effect will not rise straight. So rolling curtain doors are better than push-pull windows in three functions. This is only the reason why a large proportion of high-end residential buildings choose curtain doors.
2. Appearance comparison
The door push-pull window that appears in this book is the first building to match the overall style. Fire-proof rolling curtain door maintenance is more adjustable because of its frame. It can be the influence of any elevation, and in large landing windows, the door only occupies a small window. It is more suitable for building overall effect to seek high-grade buildings. Especially with the architect to seek a large framework, bright and transparent effect, smooth external harmonious construction. Push-and-pull windows are difficult to match the fixed glass of large grilles because they can only be pushed and pulled to a certain extent at the opening position. They are generally more suitable for open factory buildings or rural family buildings with clear arc lines.
3. Skills comparison
In processing and manufacturing, push-pull windows are generally simple in structure and have no special requirements for equipment, so they are convenient for small workshop or on-site processing and manufacturing; Jinan roll-curtain doors can become an excellent product because of the demand for better angle colliders because of the intermittent connection of aluminium alloy corner codes for window frames.
4. Ratio function
It is difficult to use in operation. Push-pull windows are popular with users because they are open actively and easy to operate. Relatively speaking, curtain doors are usually opened by hand because they are usually connected by hinges, and often not activated by windows.
In summary, the function of roll-curtain door is better than push-curtain door, but the application of push-curtain door in manufacturing and operation is better than roll-curtain door. Because of this, many doors are used in high-grade buildings such as commercial and residential buildings, office buildings, high-grade residential buildings, villas and so on, while window pushers are widely used in low-grade buildings such as industrial factories and villages.
