General home decoration projects are based on actual material prices and labor costs. The varieties and prices of decorative materials have changed rapidly, and budgets have been difficult to regulate by quotas.
The budget for decoration is a science. Households must master the scientific methods when reviewing the budget to avoid spending money.
Doing the right thing at the same price The occupants should be able to establish a reasonable investment in decoration costs in advance in light of their own economic conditions while considering the use of basic functions and the atmosphere of home furnishings.
The gross profit rate of general formal decoration companies accounts for 10% to 20% of the total project cost.
Some consumers cut the management fee of a company to 5% of the total construction cost. To maintain a reasonable profit, the decoration company will only “cut corners†on materials and labor costs, and the final victims will still be households.
Must be prepared to set aside one go before fitting enough time to design, materials, Inquiry and budget done, the more adequate preparation and decoration of speed may be faster.
Residents receive drawings and quotes and must read them carefully. It is important to note that all the renovation projects you requested have been provided. For example, did you miss the curtains and reported a missing door?
Unfortunately, there are many households. What concerns is only the last total price. But if this quotation does not include all the items you want, will it not exceed the budget in the end?
These missed projects will certainly be indispensable when they are on site. At that time, not only will they have to increase their expenditures, but they will also be “controlled by others.â€
The materials and workmanship clearly understand the drawings and quotations provided by the decoration company. They must be able to show the dimensions, practices, materials (including models, brands), and prices of the project. They cannot be described in general terms.
For example, consumers see such a price “Nippon Paint 30 yuan/square meter on the wall†is obviously not specific enough.
First of all, Nippon Paint is a lacquer brand with many products such as interior wall paint, exterior wall paint and wood lacquer. The inner wall paint is divided into several categories, each of which has many colors and prices vary widely.
Special circumstances Special budget In the wall decoration, a large area of ​​crack treatment will be charged separately.
In particular, paving gypsum board, usually plus 30 yuan per square meter or more, this fee is often not reflected in the budget, and to the site construction according to the actual situation was proposed separately.
Some families prefer to use different colors to create a certain pattern when paving tiles. The cost of this spell is usually presented at the time of settlement.
In the budget, the cost of renovating waterways and circuits is usually pre-paid at a fraction of the time, and when the project is completed, it will be settled according to the actual amount.
With regard to these special projects and budgets, tenants must have a bottom in their hearts and be able to touch the market.

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
