What factors should be considered in the design of garden iron fence

　　1）以型钢为材，断面有 几种，外表光洁，性韧易弯不易攀折，欠缺是每2-3年要油漆一次。

　　1) With section steel as material, there are several kinds of cross-section, smooth appearance, tough and easy to bend, not easy to climb. The lack is to paint once every 2-3 years.

　　2）以铁艺为材，可做各种花型，长处是不易锈蚀又价不高，欠缺是性脆又光溜度不够。订货要注意所含成分不一样。

　　2) With iron art as material, it can be used for various flower patterns. Its advantages are that it is not easy to rust and its price is not high, and the lack is that it is brittle and not smooth enough. We should pay attention to the different ingredients in the order.

　　3）熟铁、铸铝材料。质优而价高，部分花饰中或室内运用

　　3) Wrought iron and cast aluminum materials. High quality and high price, part of the flower decoration or indoor use
                                                   

　　4）各种金属网材，如镀锌、镀塑铅丝网、铝板网、不锈钢网等。如今往往把几种材料接合起来，取其长而补其短。水泥往往用作墙柱、勒脚墙。取型钢为透空局部框架，用铁艺为花饰构件。铁艺护栏部分、微小处用熟铁、铸铝。

　　4) All kinds of metal mesh materials, such as galvanized, plastic plated wire mesh, aluminum mesh, stainless steel mesh, etc. Nowadays, several kinds of materials are often combined to make up for the short ones. Cement is often used as wall column and plinth wall. The section steel is taken as the open partial frame, and the iron art is used as the decorative component. Wrought iron and cast aluminum are used in iron guardrail.

　　铁艺护栏是长型建构物。长度方向要按要求设置伸缩缝，按然而和门位安置柱位，调试因地面标高变动的立面；横向则关及围墙的强度，影响用料的体积。利用砖、水泥围墙的更简单的面凹凸、铁艺护栏构件的前后交叉位置，实际等级高的于加大围墙横向断面的尺寸，可免得去墙柱，使围墙更天然通透。

　　Iron fence is a long structure. The expansion joint shall be set in the length direction according to the requirements, the column position shall be set according to the gate position, and the elevation due to the change of ground elevation shall be debugged; the strength of the enclosure wall shall be closed in the horizontal direction, and the volume of materials used shall be affected. By using the simple concave convex surface of brick and cement fence and the front and rear cross position of iron fence components, the actual high-grade one should increase the size of the transverse section of the fence, so as to avoid removing the wall column and make the wall more natural and transparent.

　　随着社会形态的进步提高，百姓事物文化水准增长，园林铁艺护栏变成城市新亮点。

　　With the improvement of social form and the increase of people's cultural level, garden iron fence has become a new highlight of the city.
