一、明确需求与条件​

1、 Clarify requirements and conditions

用途和频率：家用选常规门；存放贵重物品或当工作室，要选防盗性强的。使用频繁就挑耐用的，减少维修。​

Usage and frequency: Conventional doors for household use; When storing valuable items or working as a studio, choose one with strong anti-theft capabilities. Choose durable ones for frequent use to reduce maintenance. ​

测量尺寸：量好门洞宽、高和车库深度，空间小选侧滑式或折叠式；空间足可选上翻式。留意周边有无障碍物。​

Measurement size: Measure the width, height, and garage depth of the door opening. If the space is small, choose a sliding or folding type; The space is spacious and can be flipped up. Pay attention to any obstacles around. ​

风格与环境：门的样式要和建筑风格搭。常遇恶劣天气，选抗风、密封性好的；临街注意隔音。​

Style and environment: The style of the door should match the architectural style. When encountering severe weather, choose one with good wind resistance and sealing performance; Pay attention to sound insulation when facing the street. ​

二、了解常见类型​

2、 Understand common types

上翻式：分手动和电动。手动适合低频使用；电动方便省力，家用居多。材质有彩钢板（便宜防锈）、铝合金（美观耐腐蚀但贵） 。​

Flip up: manual and electric. Manual is suitable for low-frequency use; Electric is convenient and labor-saving, mostly for household use. The materials include color steel plate (cheap rust proof) and aluminum alloy (beautiful and corrosion-resistant but expensive). ​

卷帘式：金属帘片，防盗、抗冲击强，占地小，适合窄小空间。开启快，但噪音大，可选静音款。​

Rolling shutter type: Metal curtain sheet, anti-theft, strong impact resistance, small footprint, suitable for narrow spaces. Quick to turn on, but loud noise, optional silent version. ​

侧滑式：横向滑动，不占垂直空间，适合上方空间不足的车库。结构简单，但开关慢，需两侧预留空间，材质有钢材和铝合金。​

Side sliding: It slides horizontally and does not occupy vertical space, suitable for garages with insufficient space above. The structure is simple, but the switch is slow and requires reserved space on both sides. The materials include steel and aluminum alloy. ​

折叠式：像手风琴折叠，适合不规则或狭小空间。铝合金坚固，塑料便宜但不耐用，密封性较弱。​

Folding: Similar to accordion folding, suitable for irregular or narrow spaces. Aluminum alloy is sturdy, plastic is cheap but not durable, and the sealing is weak. ​

三、关注材质与性能​

3、 Pay attention to materials and performance

材质​

Material

金属：钢材强度高、防盗好，但易生锈，要做防锈处理；铝合金轻、不生锈、美观，但强度低，选时注意厚度。​

Metal: Steel has high strength and good anti-theft properties, but it is prone to rusting and requires rust prevention treatment; Aluminum alloy is lightweight, rust resistant, and aesthetically pleasing, but has low strength. When selecting, pay attention to thickness. ​

复合材料：如聚氨酯夹心板，保温、隔热、隔音好，表面防锈，适合对环境要求高的车库。​

Composite materials: such as polyurethane sandwich panels, with good insulation, heat insulation, and sound insulation, rust prevention on the surface, suitable for garages with high environmental requirements. ​

性能​

Performance

：要有遇阻反弹功能，防夹人、撞车，选带锁具防护、加强边框的提升防盗性。​

Safety: It should have a rebound function when encountering obstacles, prevent people from getting caught or colliding, choose to have lock protection, and enhance the anti-theft performance by strengthening the border. ​

密封：密封条完整有弹性，门与框缝隙小，防灰尘、雨水。​

Sealing: The sealing strip is intact and elastic, with small gaps between the door and frame, and is resistant to dust and rain. ​

耐用：选大，关注弹簧、电机、轨道等关键部件质量。​

Durable: Choose a major brand and pay attention to the quality of key components such as springs, motors, and tracks. ​

四、选择开启方式与功能​

4、 Select the activation method and function

开启方式：手动便宜但费力，适合低频使用；电动便捷，可遥控，是主流选择，注意电机功率和遥控器信号。​

Opening method: Manual is cheap but laborious, suitable for low-frequency use; Electric is convenient and can be remotely controlled, which is the mainstream choice. Pay attention to the motor power and remote control signal. ​

附加功能：智能感应自动开关；远程监控可手机查看、控制；照明方便进出。按需选择，会增加成本。

Additional features: intelligent sensing automatic switch; Remote monitoring can be viewed and controlled on mobile phones; Lighting facilitates entry and exit. On demand selection will increase costs.
