Speaking of flat steel gates , I believe that most people are not very clear about its use. In fact, it is still widely used in the industrial field. Is it good or bad? Next we will take a look at the relevant content of the flat steel gate . How about flat steel gate The plane gate is mainly composed of three parts: the door leaf, the embedded member and the opening and closing device. The main body of the door leaf is generally composed of a panel, a main beam, an edge beam (pillar) and a secondary beam with a panel lattice structure. The design water pressure is transmitted to the door groove embedded part through the plate girder support, and the sub-segment gate leaf is generally connected at the side column. The lifting lugs of the plane gate are generally arranged on the top cross beam at the upper end of the main structure of the gate door leaf, and can be directly welded and fixed on the roof beam or separately manufactured according to the size and form of the structure, and then welded at the site. Flat steel gate type 1, according to the overall arrangement is divided into modular (door slot, door leaf and operating equipment as a whole) and decentralized (by the door leaf, door slot and hoist, the door leaf can be proposed when the door slot operation). 2, according to the gate door leaf assembly form is divided into the overall door leaf type and sub-section composition door leaf type. 3, according to the support of the gate leaf is divided into sliding support and rolling support. 4, according to the position of the gate leaf water stop is divided into upstream stop and downstream stop water type. 5, according to the movement of the gate leaf leaves are divided into vertical, horizontal, horizontal and floating box type, in addition, there are other classification methods (see the gate). Flat steel gate use The gate of the plane gate makes a linear motion in the gate slot to close or open the water channel. It is easy to manufacture and process, safe and reliable in operation, and convenient to maintain. It is widely used as a working gate, accident gate and maintenance on various hydraulic structures. Gates. Because the plane gate is heavy, the required door opening force is also large, and the hydraulic conditions of the gate slot are poor. Therefore, the use range of the gate as a working gate in a high-flow rate water channel is limited. With regard to the flat steel gates , I will introduce them to you. I hope to help you, and I would like to look forward to seeing more information on this site. Steel radiator steel rails outdoor steel staircase decoration purposes
Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.
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.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.
