1. The first step is to survey the site works or ask the contractor to send construction drawings. However, it is better to make a field trip, so as to understand the environment on the spot and check whether the loading and unloading roads are good.

2. Step 2: After surveying the environment, measure the cable size and buy angle iron to make angle iron bracket.

3. Finally, after the welding of angle steel bracket is completed, it can be laid on site, and the height of 10 cm can be raised with bricks and then fixed with cement slurry.

To sum up, it is necessary to prepare corresponding materials and tools, parts of the angle iron frame, box ruler, marking needle, angle grinder and carbon dioxide gas shielded welding machine for making the angle iron frame. After doing this, check whether the surrounding environment is safe and operate in a safe environment. Think about the size of the angle iron frame you made, and then simply draw a sketch and cut it according to the size. Pay attention to wearing corresponding protective equipment to prevent yourself from being hurt during operation.

After the parts of angle steel frame are cut, it is necessary to check whether there are defects and dimensional deviation, so as to make reasonable changes in time. Before 1 to 3mm, the deviation is allowed, and then the comparison process is carried out, and firm fixation is carried out to check whether the length, width and height are consistent and whether the angles are consistent. After everything is checked, fix it with pliers and prepare to enter the welding procedure. Open the carbon dioxide gas shielded welding machine, adjust it according to the thickness of the triangle iron, and then prepare to start welding the angle iron frame.
