How to install vertical pole billboards

According to the location of the attachment, cut the material and weld it. Generally, use 2.5×2.5 angle iron and weld the triangle bracket. The light box is placed horizontally, usually 20 centimeters away from the wall. Its arm length remains unchanged, and the height of the arm bracket is half of the arm length, and the diagonal braces account for 1/3 of them. If the large light box of 1.8×1.2 meters is 20 centimeters away from the wall in terms of arm length, weld two hard angle irons on it. Secure the rear side of the large light box to pre vent it from swinging. The height should account for at least 2/3 of the height of the light box.

If the light box is erected, if it is 1.3×60×20, the height of the column can be increased by no less than 2/3 of the light box. To erect a light box, 1.8×1.2×20, it must be welded into a semi-frame light frame. The top and bottom are firmly fixed. There is also a small light box, which is smaller than 1.20×0.60×0.2 and is directly connected to the aluminum gusset plate with aluminum strips. To install the angle iron frame, drill four holes with a diameter of 10 on the bracket, and then place the bracket at the location to be installed. Determine the location of the hole and drill a hole with a diameter of 8 with an impact drill. Install the expansion screw and secure it firmly, then align the bracket with the eyelet, install the nut, tighten it, and finally use large wood screws to secure the light box securely. Check again to see if it's tight. The overall appearance of the light box production depends not only on the squareness, skewness and corner joints? The greater quality standard lies in the skewness and arrangement of the fonts. Before pasting the words, be sure to check it several times. If there are people nearby, ask others to check it several times too. Is there any error?
