The following is our company’s basic introduction to purchasing telescopic doors, please refer to it.
Door row spacing
Facing today's increasingly competitive telescopic door market, some manufacturers have enlarged the door row spacing of telescopic doors in order to reduce product costs, which seriously exceeds industry standards.
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 the door rows. The basic feature of the telescopic door is telescopic operation, that is, the distance between the door rows can be large. But if it is small, the distance will be increased, and the cost will naturally be reduced.
Revealing the secret
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 , is calculated to need to be made across the main frame< br/> For telescopic doors with a spacing of 0.0, it only needs to be made across the main frame.
When produced across the main frame according to the spacing, rows can be made
When produced across the main frame according to the spacing, only rows can be made
Machine head bottom plate
The telescopic door is driven by the machine head To drive the telescopic operation of the entire door body, 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.
The cement floor has weight but no strength, the thin iron plate has strength but no weight, and the extra-thick cast iron floor has 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
br/>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. It even fell apart, so manufacturers who valued product quality changed it to a double-sliding structure. Although it increased some costs, it effectively solved this defect.
Double sliding structure, the product is 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 inclined rods run through the main straight The more the number of poles, the better the integrity and linearity (it can also be judged by the number of squares formed by the diagonal poles between the main straight poles in each span. The one with more squares is better)
After pulling apart, the diagonal The size of the upper and lower gaps on the rod
During the expansion process of the telescopic door, the inclined rod will gradually tilt. After it is fully pulled into place, there will be gaps above and below the inclined rod. The larger the upper gap, the easier it is to jump, and the larger the lower gap. The easier it is for small animals to pass through, so in order to save materials, some manufacturers increase the upper and lower neutrals by themselves, losing 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, and will not fade.
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 we identify them, we can look at the For the retractable door project installed by the company before, is the brightness of the material still there?
