Countermeasures: Longer than him
"Sun Tzu's Art of War" remarks: Knowing yourself and knowing each other is a good battle. Knowing what "deceased" the decoration company usually makes, it is possible to formulate countermeasures accordingly.
1, carefully check the budget book and drawings. See if the materials indicated on the drawings are the same as those in the budget book, and if the quantities are the same, see if everything you have to do is listed on the budget statement, whether there is a report of a door or missing the kitchen and water proofing and bedroom. In the case of baseboards and other phenomena, these projects must be done during construction. If they are missed, some procedures and expenses will be added later;
2. It is required to specify the materials and brands in the remarks column. For example, "Nippon Paint 45 yuan / square meter wall", it is easy to have disputes, because "Nippon" is just a paint brand, it has many series of products, the price of each paint are different;
3. If it is considered that the decoration company has fraud, and the amount of engineering calculations and decoration costs are in error, the decoration company may be required to re-quote, or directly to the relevant government departments to apply for a fair calculation and measurement;
4, please check master.
Master the basic principles of the budget
â— When you are basically determined to choose your target, talk to the other party about the price and strive for the maximum discount. However, the bargaining price should be based on the various aspects of the fitting-out project price obtained in the previous consultation stage, and it can be done in a definite manner, leaving the other party with a certain margin of profit, so as not to ultimately affect the construction quality.
â— Put money on the edge, determine which areas are brighter and need to spend more money, which areas can be discarded or weakened. Most materials and practices are cheap and simple, and the few finishing touches use high-priced items, so it looks like there will be a higher style. For example, the confidentiality and good abrasion resistance of the tile are higher, the wall surface can be relatively low, and the latex paint only needs to be purchased, such as the confidentiality of the tile, and the abrasion resistance is higher. The wall can be relatively Lower, latex paint only need to buy ordinary brands of more famous brands on the line.
â— During the construction process, the design of the home is well known, and the items are not arbitrarily modified and added. If changes are required, they should be adjusted according to actual conditions.

Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
