Metal Exterior Wall Panel

 

Metal exterior wall panel can play a very good decorative role on the exterior walls of buildings, but during use, there will also be problems with the panels falling off, which will affect the overall aesthetics of the building, and there are also safety issues, so what is the reason? What about the plate coming off?

1. No anchor bolts are used. The bulk density of the metal thermal insulation decorative board exceeds 50Kg, and anchors must be installed during the system installation process, and the anchors must be installed immediately after the board is pasted when the board exceeds a certain thickness, so as to ensure the middle and late bonding strength between the board and the adhesive mortar.
2. Use inferior interface agent. Phenolic is an acidic material, so be careful when using it, because of the problem of cohesive force and free acid residue, the wall of bare phenolic board must use a neutral, waterproof special interface agent to increase the cohesive force and prevent acid and alkali reaction. However, in practice, many engineering companies use inferior interface agents, causing the board to fall off.
3. Checking the remaining mortar on the peeling wall, it can be inferred that there is also a problem with the adhesive force of the mortar. The remaining mortar on the peeled off metal insulation and decorative board indicates that some of the fractured layer is on the mortar.
4. Temperature changes, temperature changes in different seasons and day and night, make the facing bricks affected by the temperature stress in the three-dimensional direction, and the facing layers will generate local stress concentrated on the vertical and horizontal walls or the junction of the roof and the wall. The middle part of the wall, or the local extrusion of adjacent bricks, will cause the bricks to fall off.
In order to effectively reduce or avoid the problem of falling off of metal carved panels, during construction, first of all, ensure that the construction wall meets the construction requirements, and secondly, strictly follow the construction steps.

 

 

 

1. Wide range of applications, old building renovation, indoor and outdoor decoration, all kinds of new buildings, can be used as wall panels, ceiling panels, decorative panels. 

2. Very light weight, easy handling and transportation, quick installation. 

3. Environmental protection and energy saving, the product has no pollution and can be recycled and reused. 

4. High hardness, good impact resistance and strong wind pressure resistance;

5. Fire retardant, non-toxic gas;

6. The double-layer curtain wall of the heat channel with metal carved decorative panels has a breathing ventilation structure and no additional structure is required.

 

 

 

 

 

 

 

Q：How long it lasts outside without bleaching？

A：The outer metal layer can not rust for 45 years, and the paint color can not fade for 15 years.

 

 

Q：Will water seep in rainy days?

A：The excellent self-structure and the compact concave-convex plug-in and buckle-groove installation method between the plates avoids the structural damage caused by the cycle of rain, snow, freezing, thawing, dry and wet, and eliminates the worry of water seepage on the wall after installation. , effectively avoid the phenomenon of mold on the indoor wall.

 

Q：Is the metal exterior wall panel sound insulation effect?

A：The core material in the middle is a thermal insulation and sound insulation layer composed of high-density polyurethane foam, and its interior is an independent closed cell structure, which has a good sound insulation effect.
