1.支架的悬臂、吊架的吊铁采用角钢或槽钢制成；斜撑的材料为角钢；吊杆采用圆钢；扁铁用来制作抱箍。

The hanging iron of the cantilever and hanger of the 1. bracket is made of angle steel or channel steel; the inclined bracing material is angle steel; the hanger uses the round steel; the flat iron is used to make the hoop.

2.支、吊架在制作前，首先要对型钢进行矫正，矫正的方法分冷矫正和热矫正两种。小型钢材一般采用冷矫正。较大的型钢须加热到900℃左右后进行热矫正。矫正的顺序应该先矫正扭曲、后矫正弯曲。

2., before the production of the hangers, the first to correct the steel, the correction of the method of cold correction and heat correction two. Cold correction is generally used in small steel. The larger steel must be heated to about 900 degrees C for heat correction. The order of correction should be corrected first and later to correct the bending.

3.钢材切断和打孔，不应使用氧气－乙炔切割。抱箍的圆弧应与风管圆弧一致。支架的焊缝必须饱满。

3. cutting and drilling of steel should not be cut with oxygen acetylene. The circular arc of the hoop should be in accordance with the circular arc of the wind pipe. The welds of the support must be full.

4.吊杆圆钢应根据风管安装标高适当截取。套丝不宜过长，丝扣末端不应超出托盘最低点。

4. the round steel of the hanger shall be properly intercepted according to the height of the installation of the wind pipe. A wire should not be too long, should not exceed the lowest end thread tray.

5.风管支、吊架制作完毕后，应进行除锈，刷一遍防锈漆。

5. when the wind pipe and the hanger are finished, we should remove rust and brush the antirust paint.

6.用于不锈钢、铝板风管的支架，抱箍应按设计要求做好防绝缘处理，防止电化学腐蚀。

6. for the support of stainless steel and aluminum plate wind pipe, the hoop should do the insulation treatment according to the design requirements, and prevent the electrochemical corrosion.
