Polyurethane Wall Panels Exterior

The top layer of polyurethane wall panels exterior is a galvanized color steel coil. The surface of the galvanized color steel coil sprayed with polyester paint is not only sprayed with various colors, but also some color steel coils are sprayed with various patterns on the surface, such as imitation marble, imitation log and decorative painting. These color steel coils will enter another equipment-metal embossing machine before entering the metal cold roll forming machine for plug joint forming. The metal embossing machine is composed of upper and lower rollers. The surface of each patterned roller will be metal-processed and carved into various patterns according to the requirements. When the color steel plate enters the embossing machine, the surface will be rolled onto the embossed roller. Various embossed patterns or textures.

Polyurethane wall panels exterior

Polyurethane wall panels exterior is a new type of wall environmental protection material developed in recent years. In fact, wall panel exterior are a kind of polyurethane color steel sandwich panels. Like the common polyurethane color steel sandwich panel structure, the exterior wall is also a hamburger or sandwich structure, but its main components and functions are different. Ordinary polyurethane color steel sandwich panels are divided into upper, middle and lower layers, in which the upper and lower layers are ordinary color steel, and the middle core layer is polyurethane foam, whose main function is fire prevention and heat preservation. The metal carving panel mainly has three layers: the upper, middle and lower layers: the raw material of the top layer is polyester paint or fluorocarbon paint color steel galvanized sheet, the raw material of the middle layer is rigid polyurethane foam, and the bottom layer is waterproof aluminum foil paper. In addition to fire protection and heat preservation, it also plays the role of wall decoration.

What are the advantages of wall panel exterior ?

1 Green and durable:

Metal faced sandwich panels has stable chemical and physical structure, will not decompose mildew, no radiation, no pollution, green environmental protection. The plate can also be flexibly disassembled and reused for installation in other buildings. The remaining leftover materials from the construction can also be recycled and reused, which greatly reduces the construction waste during the construction process. It is a high-quality, high-performance environmental protection product. The external wall insulation and decoration integrated board is easy to clean, durable and has a long service life

2 Durable and long service life：
High weather-resistant polyester paint is used to coat the alloy steel plate on the base layer by baking paint process, and the surface layer forms a dense quaternary crystal layer, which can effectively avoid cracking and falling off of ordinary coatings. The board has strong self-cleaning property, ensuring a beautiful appearance at all times, and it will not fade after 10-15 years of outdoor use; the base steel plate is made of aluminum-zinc alloy steel plate, which has strong corrosion resistance and a service life of more than 45 years.

Installation method

Preparation stage: Tools: expansion screw (for concrete and cement brick wall), dovetail nail (for steel structure construction), pistol drill, air nail gun (not necessary), marking pen, tape measure, rubber hammer, cutting machine, etc.

Installation of fitting base: before installing the plate, install the plate fitting base, mainly including the starting part, closing part, edge wrapping, middle seam, internal and external corners, etc.

Installation of plates: after the fitting base is installed, install the first plate horizontally from top to bottom and fix it on the wall with expansion screws or dovetail nails (it is recommended to fix a nail every 60 cm), then insert the female mouth of the second plate downward with the male mouth of the first plate, while tapping the interface of the two plates with a rubber hammer to ensure that the joint of the two plates is tight enough, and then fix the second plate on the wall with expansion screws or dovetail nails, The other plates are then installed in the same way. It should be noted that when the wall size is not consistent with the plate size, the installation should be continued after measuring and cutting.

Install fitting cover plate: after all plates are installed, press the fitting cover plate on the base with force. If it is a fitting of the same material, it shall be fixed on the wall with screws, and then sealed with waterproof glass adhesive.

Remove the protective film: remove the protective film after the plate is installed.
