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.

Ace wooden door 1, solid wood composite door
The door core of the solid wood composite door is mostly made of pine, fir or imported filling materials, and is covered with a density board and solid wood veneer, and is made by high-temperature hot pressing, and sealed with solid wood lines. General high-level solid wood composite door, its door core is mostly white pine, the surface is solid wood veneer. Due to the small density and light weight of the white pine, and the easier control of the moisture content, the weight of the finished door is lighter, and it is also less prone to deformation and cracking. Compared to the expensive solid wood doors, the price of solid wood composite doors is generally around 1,200-2,300 yuan. In addition, the decorative materials of modern wooden doors are more common with wood veneer and stickers, and some brands are plywood. Mupi Mumen are rich in natural texture, beautiful appearance and strong impact resistance, while the prices are relatively high; the wooden doors of stickers are also called “grain wood doorsâ€. Because of their low prices, they are more popular products. Their disadvantages are that they are easily damaged and they are afraid of water. ; Plywood to sum up the above advantages, and now relatively high cost, slightly economic strength can be considered, but the main drawback is that there is color, due to the previous election materials.
2, solid wood door (original wood door)
The solid wood door is made of natural wood taken from the forest and made of door cores. After being dried, it is processed scientifically by blanking, planing, slitting, drilling, and high-speed milling. Most solid wood doors are selected for valuable wood, such as cherry wood, walnut wood, teak wood, etc. The finished product door has the characteristics of no deformation, corrosion resistance, no cracks, and heat insulation. At the same time, solid wood doors have effectively played a role in sound insulation due to their good sound absorption.
The natural wood grain texture and color of the solid wood door is undoubtedly the best choice for the family who admire the style of return to nature. Solid wood doors have been a kind of warmth since ancient times, not only looks beautiful, beautifully carved, and diverse styles.
The price of solid wood doors also differs depending on the wood materials, textures, etc. The market price ranged from 1,500 yuan to 3,000 yuan, among which the high-grade solid wood was walnut, cherry, sabilly, rosewood, etc., while the finest teak door priced at 3000-4000 yuan. (For example, the relatively high-grade rosewood door is about 2,300 yuan; the medium-to-high-end wooden doors such as walnut, cherry, and sapphiri need 1900 yuan.) However, the process of solid wood doors in the dehydration process can not be done very well, and the relative moisture content is about 12%. After the doors are formed, they are easily deformed and cracked, and the use time is also shorter.
Purple wood door 3, molded wooden door
Molded wooden doors are favored by middle-income families because they are more affordable and safer than solid wood doors. The molded wood door is mechanically repressed by two high density fiber molded door skins with modeling and simulated wood grain. Since the door panel is hollow, the natural sound insulation effect is worse than that of a solid wood door, and it cannot be wet.
Molded wooden doors are veneered and brushed with "clear varnish" wood veneer board to maintain the decorative effect of natural wood texture. At the same time, it can also be used for panel mosaic, which is beautiful, lively and economical. Molded door also has the characteristics of moisture-proof, small expansion coefficient and anti-deformation. After a period of use, there will be no surface cracking and oxidative discoloration.
Compared to hand-made solid wood doors, molded doors use mechanized production, so their cost is also low. At present, most of the molded wooden doors on the market are at 380-500 yuan.
4, MDF molded door
The MDF is double-sided molded, the core of the door is hollow, the style is single, and the grade is low.
5, blockboard double bag door
Semi-manual semi-mechanized production, door core pine frame, fine wood door two bread, single style, flat door-based, low grade.
6, all solid wood door structure
Simple mechanical production, all solid wood, there are pine, Tishan wooden, beech, Ash and other materials, its structure is mainly linked to the door frame, inlaid door panel, in the market is a high-end products. Due to the reasons of all solid wood, there are fatal defects in the quality: the door body is easily deformed, the crucible joint cracks, and the door core board shrinks white.
