The two exterior wall products of Jiamei HD and Jialai are generally fixed through penetration. Our company will provide professional matching blind rivets of the same color as the board, and other related accessories. When installing the board, first connect the keel to the main structure of the building through the adjustable support, and then use the rivet to penetrate the board on the supporting keel. The whole process is dry work, convenient and fast. The entire external wall system is safe and stable, durable, and has excellent wind resistance and earthquake resistance. Even in natural disasters such as typhoons and earthquakes, it is unlikely that the board will fall off or the external walls will collapse.
