American standard H-shaped steel

When loading and unloading galvanized H-beams, if possible, we must strive to avoid direct contact with wire ropes, fasteners, etc. In addition, for shelves storing galvanized H-beams, it is also necessary to directly separate them from carbon steel components using wooden boards or rubber sheets, and then prepare a series of special tools such as hammers, wooden hammers, and copper hammers, as well as hot-rolled flat wire brushes.

In addition, when we use galvanized H-shaped steel, we should be careful not to directly hit its surface with a hammer, nor should we use square steel pipes to directly contact our carbon steel bracket. We need to place hot-rolled steel plates and plastic sheets between the bracket and our pipeline. In addition, we also need to place rubber sheets or other insulation materials. By doing so, we can prevent corrosion caused by carburization and potential difference in American standard H-shaped steel.

For galvanized H-shaped steel, sleeves also need to be installed when it passes through walls or floors For the gap between the sleeve and pipeline, it is also greater than 10 mm. If it is within its gap, an insulation layer needs to be added. For insulation, try not to contain iron filings, rust, and other items. For insulation, asbestos rope is usually used.

For galvanized H-shaped steel head pipes, they can be directly connected to prefabricated hot-rolled flat steel tees, such as steering pump pipes, and then glued with hot-rolled flat steel. Then, the branch pipes need to be directly connected to the holes on the head pipes, and in addition, a drill bit and its milling cutter need to be used for mechanical processing. If you want to use carbon arc gouging or plasma cutting, you also need to use a polishing machine for polishing
