When transporting the PC board, be careful not to scratch the ground or damage the edges. Use scissors or drilling tools to cut to the required size, then peel off the protective film of about 50mm along each side and install it, and then tear off the rest until the installation is completed. It should also be noted that all open edges should be sealed with appropriate film to prevent water, dust or other impurities from intruding

The minimum bending radius of the hollow plate is 175 times its thickness, and it can only be cold-formed, not hot-formed

The minimum bending radius of a solid plate is 150 times its thickness. The thickness of less than 6mm can be cold-formed and hot-formed, and the thickness of more than 8mm requires hot bending.

The PC board should be installed in the direction of the frame to make the water drop down. The top edge of the board should be sealed with anti-seepage and dust-proof aluminum foil. The bottom of the board is covered with a special perforated aluminum foil with a bottom to allow the condensed water to flow away

It is necessary to reserve space for the thermal expansion of the PC board, and reserve about 3m m for every 1000m m long board, and ensure sufficient groove depth. The hole diameter should be greater than 1.5 times the screw diameter

The sealing system is divided into dry system (using EPD M or other compatible adhesive strips) and wet system (using approved neutral silicone sealant). PVC materials cannot be used for sealing.
