It features light weight, high strength, rich colors, convenient and fast construction, earthquake resistance, fire resistance, rain resistance, no exposed nails, long service life and maintenance-free.
Plate type characteristics
It adopts wavy arcs, with a smooth appearance, fully meeting the modern architectural creativity
The plate type is narrow, with a nail spacing of 315mm. It has high strength and excellent mechanical properties, and has a significant effect in resisting typhoons
It has an attractive appearance and the color can be freely chosen according to the designed image. The range of decorative effects is wide
The installation is quick and easy. Installed from bottom to top in sequence, it reasonably solves the problem of vertical lap leakage
It is used for on-site composite wall surfaces, effectively addressing drawbacks such as rainproofing and water overflow
The board surface installation adopts a hidden nailing method, presenting a simple and elegant appearance. Eliminate the rust source of exposed nail holes and extend the service life of the board
The raw material is 500mm in size, which is exactly two equal parts of a 1-meter-wide board, making rational use of the material
