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

　　1）以型鋼為材，斷面有 幾種，外表光潔，性韌易彎不易攀折，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）以鐵藝為材，可做各種花型，長處是不易銹蝕又價不高，欠缺是性脆又光溜度不夠。訂貨要注意所含成分不一樣。

　　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）熟鐵、鑄鋁材料。質優而價高，部分花飾中或室內運用

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

　　4）各種金屬網材，如鍍鋅、鍍塑鉛絲網、鋁板網、不銹鋼網等。如今往往把幾種材料接合起來，取其長而補其短。水泥往往用作墻柱、勒腳墻。取型鋼為透空局部框架，用鐵藝為花飾構件。鐵藝護欄部分、微小處用熟鐵、鑄鋁。

　　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.

　　鐵藝護欄是長型建構物。長度方向要按要求設置伸縮縫，按然而和門位安置柱位，調試因地面標高變動的立面；橫向則關及圍墻的強度，影響用料的體積。利用磚、水泥圍墻的更簡單的面凹凸、鐵藝護欄構件的前后交叉位置，實際等級高的于加大圍墻橫向斷面的尺寸，可免得去墻柱，使圍墻更天然通透。

　　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.

　　隨著社會形態的進步提高，百姓事物文化水準增長，園林鐵藝護欄變成城市新亮點。

　　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.
