<p>What is the difference between a <a href="https://www.chihardwares.com" rel="noopener noreferrer" target="_blank"><a href="https://www.chihardwares.com" target="_blank">garage door</a></a> and a garage rolling door? The editor will give you the following explanation: garage doors are generally called garage doors, and garage rolling doors are generally called rolling doors.</p><p>The motorized garage door is mainly composed of door panels, electric door motors, hardware accessories, and balance systems.</p><p>door panel features:</p><p>1. The surface of the fine-grained embossed door body presents irregular powder spraying texture, which has a strong embossing effect, which not only increases the strength, but is also beautiful.</p><p>2. High-strength double-sided high-quality dipped galvanized steel sheet is used, and long-life paint (pure polyester) is sprayed on both sides, which has strong corrosion resistance.</p><p>3. The outer end of the high-quality steel plate is wrapped so that the inner and outer sides are attached together, and the two walls are better sealed.</p><p>4. The sandwich layer is made of highly solid polyurethane foam, which can increase the effect of heat preservation and sound insulation.</p><p>5. The bottom of the door is equipped with a "U"-shaped sealing strip, which is more cold and windproof.</p><p>Motor characteristics:</p><p>1. Automatic delay lighting: When the garage door is opened or closed, the lighting will turn off automatically after 2.5-5 minutes.</p><p>2, maintenance-free DC motor, strong power, stable operation, lowest noise.</p><p><br></p><p>3. Toroidal transformer, energy saving rate 70%</p><p>4. Planetary gear switch, Hall element sensor, pulse.</p><p>5. Program control, convenient operation and complete functions.</p><p> Hardware Accessories:</p><p>1. The guide rail is made of 1.5mm Baosteel cold-rolled steel plate with silver plating on the surface.</p><p>2. The rollers are made of high-strength wear-resistant poly-formaldehyde POM engineering plastics with embedded ball bearings.</p><p>3. The door hinge is made of 1.5mm Baosteel cold-rolled steel plate with silver plating on the surface.</p><p>4. The steel wire reel is made of high-strength aluminum alloy.</p><p>Balance system:</p><p>(1) The balancer adopts torsion spring balance system.</p><p>(2) The balance system casing adopts galvanized steel pipe.</p><p>(3) 65 manganese is added to the torsion spring material of the garage door to increase the fatigue resistance and extend the service life by 2-3 times.</p><p>garage door features:</p><p>1. The appearance is beautiful and fashionable, the surface is painted, durable, resistant to sunlight, rain, corrosion and scratches.</p><p>2, a variety of installation methods are available, including exterior, interior, and middle installation; installation does not require high space and does not occupy the internal space of the garage door.</p><p>3. It can rebound and recover after a slight collision, and it can be replaced by a single chip if it is damaged.</p><p>4. Easy installation, fast construction speed and saving construction period.</p><p><br></p>
