What must we know when installing roller shutter doors? Jinan roller shutter door is mainly composed of shutter, guide rail and transmission device. Jinan roller shutter door does not occupy the indoor and outdoor area when it is opened, and it is suitable for tall openings that are not frequently opened. The width of the roller shutter door should adapt to the rigidity of the shutter, and its processing, manufacturing and installation requirements are also high.
There are mainly two types of curtain boards, namely, leaf board and empty format, in which the leaf board is used more frequently. The sheet curtain is rolled from galvanized steel sheet or aluminum alloy sheet. The sheets are connected by rivets.

When it is opened, the leaf plate rises along the guide rails on both sides of the door opening and is rolled on the drum.
The transmission device of the rolling shutter door is installed on the upper part of the door opening, which is divided into four types: movable, chain, rocker and electric. The driving device of the manual Jinan roller shutter door includes a drum, a bracket, a spring bearing, etc.
It uses spring bearings to balance the deadweight of the door leaf, so the door should not be too large. Both ends of the bottom stiffening plate are inserted with pins into the side guide rail to fix the door.
The chain type Jinan roller shutter door is driven by a chain and several gears with different diameters to reduce the opening and closing weight.
Rocker type roller shutter is used to change the transmission direction with rocker and umbrella gear. It is convenient to open and close. It is often used to open and close the empty type roller shutter, which is more economical than electric type roller shutter.
The motor of the electric roller shutter door is mostly installed on the upper part, exposed or set in the wall, and the reducer can be separated from the motor or designed as an integral part.
