>Beijing installation electric telescopic door
manufacturers produce windproof telescopic doors, rail and trackless telescopic doors with gun tip telescopic doors, stainless steel telescopic doors, etc. We provide you with all-day telescopic door maintenance services and sales of telescopic door motors and telescopic door controllers. Telescopic door remote control. Please refer to the following for our company’s basic introduction to purchasing telescopic doors.
Door row spacing
In the face of today's increasingly fierce competition in the telescopic door market, some manufacturers have extended the door row spacing of telescopic doors to significantly exceed industry standards in order to reduce product costs.
Generally, the price of telescopic doors is calculated based on linear meters. Therefore, most users only pay attention to the total length of the telescopic door and ignore the distance between door rows. The basic feature of telescopic doors is telescopic operation, that is, the distance between door rows can be large or small. The big cost will naturally be reduced.
Revealing
The cost difference between the door row spacing and the cost
Taking the telescopic door (excluding the driving part) as an example
The telescopic door with a spacing of />Telescopic doors with a spacing of 0.05 Å only need to be made across the main frame.
Rows can be made by the specified spacing across the main frame
Rows can only be made by the specified spacing across the main frame
Machine head bottom plate
The telescopic door is driven by the driving part of the machine head The entire door body telescopically operates, so the weight and strength of the machine head bottom plate are particularly important. Currently, there are three types of bottom plates on the market: cement bottom plate, thin iron plate and cast iron bottom plate.
Cement base plates have weight but no strength. Thin iron plates have strength but no weight. Extra-thick cast iron base plates have both weight and strength.
Shuangxing uses ultra-thick cast iron to make the base plate of the machine head. For longer telescopic doors, the counterweight will be increased proportionally to make the telescopic door run more smoothly.
Sliding structure
The sliding of telescopic doors with long inclined rods is divided into single sliding and double sliding
There is a fixed point and a sliding point between the single sliding inclined rod and the main straight rod
/> There is a fixed point and two sliding points between the double sliding inclined rod and the main straight rod
Early telescopic doors were all single sliding structures. After long-term operation, most telescopic doors became loose or even fell apart. Therefore, manufacturers that attach great importance to product quality have changed it to a double-sliding structure. Although it increases some costs, it effectively solves this defect.
Double sliding structure products are more stable
Grid structure of inclined rods
The inclined rod structure of the telescopic door determines the integrity and linearity of the telescopic door. The number of inclined rods running through the main straight rods The more integrity and linearity, the better (you can also judge the number of squares formed by the diagonal bars between the main straight bars in each span to judge the number of squares)
The size of the upper and lower gaps on the diagonal bars after opening< br/> During the expansion process of the telescopic door, the diagonal bar will gradually tilt. When all is pulled into place, gaps will appear above and below the diagonal bar. The larger the gap above, the easier it is to jump over. The larger the gap below, the easier it will be for small animals to pass through. In order to save materials, some manufacturers will The upper and lower neutrals increase by themselves and lose part of the function of the gate.
Electrophoresis material
The surface of most aluminum profiles of telescopic doors is treated by electrophoresis and oxidation. After electrophoresis treatment, the surface of the material can be guaranteed to be smooth and bright for a long time without fading.
There are some processes on the market that can achieve smooth and bright effects in a short period of time, but these processing methods gradually lose their original effects over time. When identifying, we can look at the telescopic lenses previously installed by the company. Whether the brightness of the door engineering material remains.
Be sincere and sincere. Sincerity establishes a bridge of communication with customers and true love is the prerequisite for providing good anti-theft door installation and maintenance services. Sincerity can make customers rest assured of us. Contact Han Zhenlong phone number
