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、普通材质及工艺：

1、 Common material and process:

1、采用材料：采用非标Q-220B级钢。

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

2、电焊工艺：采用手工电焊技术。

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

3、细节处理：冷镀锌或不镀锌。 油漆：均采用天津、无锡等地区生产的灯塔等油漆。

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

二、高档材质及工艺：

2、 High grade material and process:

1、制作铁艺大门采用的材料：采用优质的国标Q-235A级钢。

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

2 、电焊工艺：采用二氧化碳气体保护焊。(焊接点应均匀，气密性能较强，牢固度为佳) 电焊条。

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、细节处理：室外均采用热镀锌加工

3. Detail treatment: hot dip galvanizing is used outdoors
