As a new building material, color steel sandwich panel can be widely used in the construction of various industries in a short time, especially in the field of purification engineering, which is mainly due to its unique characteristics. It not only has
excellent fire insulation effect, but also is more convenient for construction and installation, saving construction time and cost.
With the development of color steel plate, it can be divided into manual plate and machine-made plate according to the different production process. The machine-made board is directly processed and compounded by the sandwich panel production equipment.
Although the production is fast and convenient, the machine-made board is not as good as the manual board in terms of strength, flatness and beauty due to the direct composite of the machine through the machine, and there is no steel belt inside and no
keel at the edge wrapping position.
In contrast, manual board production requires manual addition of sandwich materials and glue, which is formed by manual folding, with built-in steel strip and external keel, which makes the manual board superior
to the machine-made board in strength and appearance. Due to the complex production process, manual operation is required, which greatly increases the labor cost and makes the price of manual board higher than that of machine-made board.
of construction, the specification of the manual board is determined according to the engineering requirements of the demander. Before production, the number and size of the hand-made board have been matched well. During the installation, it only needs
to be assembled and installed according to the requirements. Since the manual board has been matched before the construction, the project cost can be greatly reduced. However, it is worth noting that before production, the manual board must be accurately
matched. If the calculation is wrong, it will be more troublesome, because the manual board can not be cut, unless it is the corner position.
Although the strength and flatness of the machine-made board are not as good as that of the hand-made board,
when the quantity and specification of the machine-made board are not as accurate as that of the manual board, because it is directly compounded by the machine, there is no steel belt inside and no keel on the outside, so it can be cut arbitrarily when
installing, but this undoubtedly causes waste of various materials in the engineering construction.
