市场对铝艺大门的定义是，一个好的常州铝艺大门，必须要有好的气密，水密，隔音，隔热，抗风压，并在设计上，必须考虑以下几点：尽量减少型材截面大部分的型材批发商或者常州铝艺大门厂家都面临一个相同的问题，型材品种繁多，且容易积压，影响资金流动及管理的困难。比如，不隔热窗，在设计型材时，若考虑内开，外开，活动百叶的共用性，即可以减少型材截面的品种。

The system's definition of aluminium door is that a good aluminium door must have good air tightness, water tightness, sound insulation, heat insulation and wind pressure resistance. In design, the following points must be considered: to minimize the section of most of the profile wholesalers or Changzhou aluminium door manufacturers are facing the same problem, profile products. There are many kinds, and they are easy to backlog, which affects the flow of funds and the difficulty of management. For example, when designing profiles without thermal insulation windows, if we consider the commonality of inside, outside and movable shutters, we can reduce the variety of profiles section. 2)配件，角码，胶条的统一化。

2) Unification of accessories, corner codes and tapes.

3)工艺的统一，简单化一般的铝艺大门设计，主要考虑型材断面及五金的配合。很少考虑现场工人生产，制造的方便。如果工人的生产效率愈高，品质的合格率愈高，相对的生产成本就愈低。

3) Unification of technology, simplification of general aluminum door design, mainly considering the profile section and hardware coordination. Few consideration is given to the convenience of on-site production and manufacture. If the productivity of workers is higher, the qualified rate of quality is higher, and the relative production cost is lower.

4)完善的接点，迎合不同的开启方式建筑设计师在设计工程时，经常为了建筑物优美的造型效果，会有不同的铝艺大门需求。因此，为了配合工程，良好的系统只要做少部分修改，即可满足需要，不须另起炉灶。对于门与窗，推拉窗(门)与平开窗(门)的接点，亦要有良好设计，不致产生好几根铝型材连在一起，影响视觉美观。同时，并能满足不同的开启需求，如外开，内开，内开内导，外翻，内翻，推拉等功能。

4) Perfect joints cater to different opening modes when architects design projects, often for the beautiful shape effect of buildings, there will be different requirements for aluminium art doors. Therefore, in order to cooperate with the project, a good system can meet the needs with only a few modifications, without having to start a new stove. For doors and windows, the connection between sliding windows (doors) and flat windows (doors) should also be well designed so as not to produce several aluminium profiles connected together, affecting the visual beauty. At the same time, it can meet different opening needs, such as opening outside, opening inside, opening inside, turning out, turning in, pushing and pulling, etc.

5)良好的整体公差配合，完善的生产工艺 窗结构是由铝型材，玻璃，隔热条，胶条，五金件及加工工艺配合完成，如果没有良好的公差配合，很难生产合格的铝艺大门，因此系统公司在这方面就起到主导的作用。试想我们开的汽车，各个零部件若没有好的公差配合，其结果将会如何欧洲对于铝艺大门的制造销售，均要求必须通过常州铝艺大门实验室的检测(如德国的ROSEHEIM )，检测的标准也有明确规定(详看CENTC33)。为了通过检测，良好的公差配合，持续且完善的制作工艺是必须的，例如为了"水密"及防止室内外温差造成“结露”，“排水孔”及“通风孔”的设计就至关重要。

5) Good overall tolerance coordination, perfect production process window structure is completed by aluminum profiles, glass, insulating strips, rubber strips, hardware and processing technology. Without good tolerance coordination, it is difficult to produce qualified aluminium door. Therefore, the system company plays a leading role in this regard. Imagine our car, if there is no good tolerance for all parts, how will the result be for the manufacture and sale of aluminium door in Europe? It is required to pass the test of Changzhou aluminium door laboratory (such as ROSEHEIM in Germany), and the test standard is also clearly stipulated (see CENTC33 for details). In order to pass the test, good tolerance coordination, continuous and perfect production process is necessary, such as in order to "water tightness" and prevent indoor and outdoor temperature difference caused by "condensation", "drainage hole" and "ventilation hole" design is essential.

6)对材料的要求：

6) Requirements for materials:

A、五金件：由于铝材与铁材五金存在电位差的关系，易造成铝材腐蚀，因此冷(热)轧铁五金件不宜采用。一般使用的材料，在符合强度的前提下，以不锈钢，铝合金，锌合金及工程塑料为主。

Hardware: Because of the potential difference between aluminium and iron, it is easy to cause corrosion of aluminium, so cold (hot) rolled iron hardware should not be used. Generally used materials are stainless steel, aluminium alloy, zinc alloy and engineering plastics on the premise of conforming to strength.

B、胶条：以三元乙丙(EPDM)为主，寒冷地区需要采用硅橡胶。欧洲汽车，均采用EPDM为胶条，对于住家铝艺大门的要求，当然也用此材料。

B. Adhesive tape: EPDM is the main type. Silicone rubber is needed in cold areas. European automobiles, all use EPDM as adhesive tape, for home aluminum door requirements, of course, also use this material.

C、隔热条：以尼龙66加25%的玻纤为主。目前尚无其他材料取代，若以PVC代替尼龙66，造成的后果，在实验室均有报告。

C. Insulation strip: nylon 66 plus 25% glass fiber. At present, no other material has been replaced. If nylon 66 is replaced by PVC, the consequences are reported in the laboratory.
