As a technical activity, the construction of Jinan iron gate needs attention in many places. Here are some problems that should be paid attention to in the construction and acceptance of iron gate:

一、普通材質及工藝：

1、 Common material and process:

1、采用材料：采用非標Q-220B級鋼。

1. Materials used: non-standard q-220b steel.

2、電焊工藝：采用手工電焊技術。

2. Electric welding process: manual electric welding technology is adopted.

3、細節處理：冷鍍鋅或不鍍鋅。 油漆：均采用天津、無錫等地區生產的燈塔等油漆。

3. Details: cold galvanized or non galvanized. Paint: lighthouses and other paints produced in Tianjin, Wuxi and other areas are adopted.

二、高檔材質及工藝：

2、 High grade material and process:

1、制作鐵藝大門采用的材料：采用優質的國標Q-235A級鋼。

1. Materials used for making iron gate: high quality national standard q-235 class a steel.

2 、電焊工藝：采用二氧化碳氣體保護焊。(焊接點應均勻，氣密性能較強，牢固度為佳) 電焊條。

2. Electric welding process: carbon dioxide gas shielded welding is adopted. (the welding points shall be uniform, with strong air tightness and good firmness) electrode.

3、細節處理：室外均采用熱鍍鋅加工

3. Detail treatment: hot dip galvanizing is used outdoors
