停车棚这东西，看着就是几根柱子加个顶，但做对了管十年，做错了年年修。同样是停车棚，膜结构的、钢结构的、铝合金的，防晒效果、抗风能力、使用寿命差出好几倍。选之前先把几个基本问题搞清楚。

The parking shed looks like just a few pillars and a roof, but if done correctly, it will be managed for ten years, and if done incorrectly, it will be repaired every year. The same parking shed, with membrane structure, steel structure, and aluminum alloy, has several times worse sun protection effect, wind resistance, and service life. Before making a choice, clarify a few basic questions.

先分清两类主流结构，适用场景完全不同。

First, distinguish between the two mainstream structures, which have completely different applicable scenarios.

膜结构停车棚是近年主流。核心是张拉膜材加钢结构骨架，膜材表面经过PVDF涂层处理，能反射大部分紫外线，棚下温度比普通彩钢瓦棚低好几度。膜材自重轻，对骨架的承重要求低，可以做很大的跨度，造型也灵活，弧形、波浪形大多能实现。缺点是膜材有使用寿命，一般10到15年需要更换，且膜面容易被尖锐物划伤。

Membrane structure parking shelters have become mainstream in recent years. The core is the combination of tensioned membrane material and steel structure skeleton. The surface of the membrane material is treated with PVDF coating, which can reflect most of the ultraviolet rays. The temperature under the shed is several degrees lower than that of ordinary color steel tile sheds. The membrane material has a light weight and low load-bearing requirements for the skeleton. It can achieve large spans and flexible shapes, including curved and wavy shapes. The disadvantage is that the membrane material has a service life, usually requiring replacement after 10 to 15 years, and the membrane surface is easily scratched by sharp objects.

钢结构停车棚配彩钢瓦或阳光板，造价低、施工快，但彩钢瓦隔热差，夏天棚下闷热；阳光板透光但老化快，几年后发黄变脆。钢结构本身的防腐处理是关键，热浸镀锌比普通刷漆耐候性强得多。

Steel structure parking sheds equipped with color steel tiles or sun panels have low cost and fast construction, but the insulation of color steel tiles is poor, making it hot and humid under the shed in summer; Sunlight boards are transparent but age quickly, turning yellow and brittle after a few years. The anti-corrosion treatment of the steel structure itself is crucial, and hot-dip galvanizing has much stronger weather resistance than ordinary painting.

抗风是停车棚的命门，青岛济南都得按这个标准来。

Wind resistance is the lifeline of parking shelters, and both Qingdao and Jinan must follow this standard.

停车棚属于半开放结构，风荷载是主要受力来源。正规设计要按当地基本风压取值，济南地区基本风压在0.45kN/m?左右，青岛沿海更高。抗风能力取决于三个因素：骨架的截面尺寸和壁厚、基础的形式和埋深、膜材或屋面板与骨架的连接方式。立柱基础用独立基础还是条形基础，埋深够不够，直接决定大风天棚子会不会被掀翻。选厂家时问清楚按什么风压标准设计、基础怎么做，比只看效果图实在。

The parking shed belongs to a semi open structure, and wind load is the main source of stress. A formal design should be based on the local basic wind pressure value. The basic wind pressure in Jinan area is 0.45kN/m? On the left and right, the coastal areas of Qingdao are higher. The wind resistance ability depends on three factors: the cross-sectional size and wall thickness of the skeleton, the form and burial depth of the foundation, and the connection method between the membrane material or roof panel and the skeleton. Whether to use an independent foundation or a strip foundation for the column foundation, and whether the burial depth is sufficient, directly determines whether the shed will be overturned in windy weather. When choosing a manufacturer, it is more practical to ask clearly what wind pressure standard to design according to and how to build the foundation, rather than just looking at the rendering.

膜材分等级，别只看颜色。

Film materials are graded, don't just look at color.

张拉膜材按涂层和基布分档，PVDF涂层是标配，抗紫外线和自洁性好；PTFE涂层性能更强但价格高出一截。膜材的克重、拉伸强度、防火等级都要看检测报告，B1级防火是底线。有些低价棚用的是劣质膜材，一两年就褪色、变脆、开裂，换膜的钱比当初省的多。

Stretch film materials are classified according to coating and base fabric, with PVDF coating as standard, which has good UV resistance and self-cleaning properties; PTFE coating has stronger performance but is priced higher. The weight, tensile strength, and fire rating of the film material all depend on the test report, with B1 fire rating being the bottom line. Some low-priced sheds use inferior film materials, which fade, become brittle, and crack within one or two years, saving more money on replacing the film than before.

选厂家，盯三条。

Choose a manufacturer and focus on three aspects.

一看有没有自有加工能力。膜结构停车棚的膜材裁剪、热合拼接需要专业设备，钢骨架的切割焊接也要工厂完成，纯倒手的中间商，尺寸错了返工都找不到人。二看有没有本地安装团队。停车棚是现场组装的活，基础浇筑、骨架吊装、膜材张拉，每一步都影响非常终效果，外地厂家发货外包安装，出了问题扯皮非常麻烦。三看案例和质保。做过小区、学校、医院停车棚的厂家，对使用场景和安全要求更熟悉；质保条款写清楚膜材和钢结构的保修年限，比口头承诺管用。

Check if you have your own processing capability. The cutting and heat sealing of the membrane material for the membrane structure parking shed require professional equipment, and the cutting and welding of the steel frame also need to be completed by the factory. The middleman is purely manual, and if the size is wrong, they cannot find anyone to rework. Check if there is a local installation team. The parking shed is an on-site assembly process, involving foundation pouring, skeleton lifting, and membrane material tensioning, each step affecting the final effect. Outsourcing installation from outside the factory can be the most troublesome when problems arise. Three perspectives on case studies and quality assurance. Having worked as a manufacturer of parking sheds in residential areas, schools, and hospitals, I am more familiar with the usage scenarios and safety requirements; The warranty terms clearly state the warranty period for membrane materials and steel structures, which is more effective than verbal promises.

停车棚不是买回来一装了事的东西。结构选对场景、抗风算准标准、膜材认准等级、厂家找靠谱的——这四条守住了，车子才真正被保护住，而不是年年修棚子。

A parking shed is not something that can be bought and installed. By selecting the right scene for the structure, wind resistance calculation standards, identifying the grade of the membrane material, and finding reliable manufacturers - these four principles are upheld, and the car is truly protected, rather than being repaired every year.
