When the steel grating is packaged and transported, try to prevent it from being hit, squeezed and impacted. The steel grating is a kind of steel product with a square grid in the middle, which is made of flat steel and cross-arranged at a certain interval and cross-bars. The steel grating is mainly used as a gutter cover. , Steel structure platform slabs, treads of steel ladders, etc. Crossbars generally use twisted square steel.
When welding the steel grating, the flat steel is straightened first and then the process welding is carried out. There are generally three packaging methods for steel grating in steel grating plants: strapping, generally suitable for relatively neat steel grating; screw rod fixing, using 4 screw rods to pass through the steel grating aperture, and locking with screws Guarantee method; pallet guarantee, generally for export packing. It is mainly determined according to the customer's situation. If there are not many goods, and there is no need to load and unload with a forklift, it is generally more convenient to load and unload in bulk. On the contrary, there are more goods, it is more convenient to use forklift to load and unload the general packing. In short, all for the convenience of the customer, the protection of the product during transportation shall prevail. If the flat steel shows an arc (explanation: an elegant line) bent (Bend) pattern, at the time of welding, the flat steel is not straightened, but such flat steel is placed directly Welding on the die looks straight on the surface. In fact, the steel grating already has relatively strong internal stress at this time.
In pickling and before, the steel grating was handled to remove internal stress. If the internal stress comes out, the appearance becomes a horizontal bow. This kind of situation arises without being valued. In modern industrial production, such problems usually do not arise.
