As a natural material, natural stone application is very atmospheric at home, especially for larger rooms, but natural stone flooring has many defects, especially its safety and environmental protection are not very good, so no It is recommended to use a family with elderly and children at home. Moreover, there is a big problem with the overall paving of natural stone, that is, the weight, the natural stone is relatively heavy, will increase the load of the floor, so it is best to refer to the architectural drawings when using. 1. Paving natural stone first requires the ground to be level and the base layer to be clean. Therefore, it is necessary to level the unevenness. The base layer of the paving should not have mortar, especially white ash mortar and oil stains, and wet the ground with water before paving. 2. When paving on the ground, be sure to place the standard block. The standard block should be placed at the intersection of the crosshairs and paved diagonally. 3, paving stone and paving tiles have many similar places, such as water soaking, but the requirements of paving stone more, in addition to the general operation in the paving operation, but also each line in turn, and need The water soaked in the stone is dry and wiped on the back before it can be laid. Moreover, the maintenance of the later stage is also very important. The stone floor must be sprinkled for maintenance after 24 hours of installation, and the sawdust should be covered after the paving. 4, decoration matters needing attention Stone has a certain degree of radiation, so pay attention to ventilation after paving, and it is best not to stay within 1 month after paving. Stones must be soaked in water and dry, so as not to affect the coagulation and hardening of the stone, resulting in problems such as empty drums and shelling. After the paving is completed, the stone should not be used within 2~3 days.

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.
