What is Great Wall Metal Siding?
Great Wall Metal Siding is a decorative and functional cladding solution characterized by evenly spaced grooves or ribs across the IND panel surface. Inspired by historical stone masonry and the rhythmic lines of the Great Wall, this profile adds depth, shadow effects, and a sense of structure to building façades.
It is available in a wide range of surface finishes—from warm wood grains to industrial metallic colors—allowing architects to integrate it into diverse architectural styles. Panels can be installed horizontally for a streamlined look, or vertically to emphasize height.
The fluted geometry also enhances surface rigidity, making the panel resistant to dents, bending, and other physical damage.
Material Composition and Technical Specifications
The outstanding performance of great wall panel comes from its carefully engineered multi-layer composition:
| Layer | Description |
|---|---|
| Surface Layer | High-strength alu-zinc pre-painted steel sheet, 0.21–0.32 mm thick. |
| Insulation Core | Polyurethane (PU) or Polyisocyanurate (PIR) foam, providing excellent thermal and sound insulation. |
| Back Layer | Aluminum foil or coated paper backing for moisture resistance. |
| Panel Width | Commonly 383 mm, customizable to project requirements. |
| Panel Thickness | 15–25 mm, with insulation thickness |
| Flute Depth | 5 mm depending on design. |
| Surface Finishes | Wood grain, stone texture, matte, metallic, or custom colors. |
| Installation | Hidden fastener interlocking system. |
Manufacturing Process
The production of metal great wall panel involves several precision steps:
- Metal Coil Preparation – High-quality steel coils are uncoiled and cleaned to remove any contaminants.
- Roll Forming – The sheet passes through roller stations that shape the distinctive fluted profile.
- Surface Coating – Protective and decorative coatings are applied for UV resistance and long-term color retention.
- Insulation Injection – PU or PIR foam is injected under high pressure to ensure consistent density.
- Cutting and Quality Inspection – Panels are cut to length, checked for dimension accuracy, and inspected for defects.
- Packaging – Panels are safely packed to prevent damage during transportation.
Design Advantages & Benefits
Distinctive Aesthetics – The fluted pattern produces dynamic light and shadow effects that change with the sun’s position.
Versatility – Can function as fluted wall board, acoustic wall panel, or great wall panel for both exterior and interior applications.
Customizable Styles – Available in a variety of textures, patterns, and colors to suit different design themes.
Structural Strength – Fluted geometry improves rigidity and impact resistance.
Hidden Fixing System – Concealed fasteners create a clean, seamless appearance.
Applications
Great Wall Metal Siding is suitable for a variety of projects:
- Commercial – Shopping centers, office buildings, exhibition halls.
- Residential – Villas, apartment blocks, and townhouses.
- Public Infrastructure – Schools, hospitals, transport hubs, and government buildings.
- Renovations – Upgrade outdated façades without heavy construction.
- Interior Design – Hotel lobbies, reception areas, and feature walls.
Installation Guide
The hidden fastener system allows for fast and secure installation:
- Substrate Preparation – Ensure the wall surface is flat and stable.
- Framework Installation – Fix steel or aluminum battens as the mounting structure.
- First Panel Placement – Secure the concealed side of the panel to the batten.
- Interlock Panels – Snap subsequent panels into place, ensuring alignment.
- Final Trims – Use corner and edge trims for a neat finish and weather protection.
Maintenance and Longevity
Great Wall Metal Siding requires minimal upkeep. Routine cleaning with water and mild detergent is sufficient. Unlike traditional siding, it does not require repainting, and the anti-corrosion coating ensures a service life of 20–30 years, depending on environmental conditions.
As sustainable construction gains importance, great wall metal siding aligns perfectly with eco-friendly goals. The insulated core lowers building energy consumption, while the steel components are fully recyclable. Its lightweight nature reduces transportation energy costs, making it both an environmentally and economically responsible choice.
Whether referred to as great wall panel, fluted wall panel, or great wall metal siding, this innovative cladding offers a winning combination of style, durability, and performance. It delivers thermal insulation, acoustic control, weather resistance, and aesthetic appeal in a single product.
For architects and builders looking to create modern, energy-efficient, and visually striking buildings, Great Wall Metal Siding stands out as a versatile, high-value solution ready to meet the needs of contemporary construction.
Specifications of Decorative PU Wall Sandwich Panels
Decorative PU wall sandwich panels represent a revolutionary approach to modern construction, combining aesthetics with practicality. These panels boast a range of specifications that make them an attractive choice for a variety of applications:
1. Core Material: At the heart of decorative PU wall sandwich panels lies a core material made of polyurethane foam. This material is prized for its exceptional thermal insulation properties, helping to maintain comfortable indoor temperatures while reducing energy consumption. Additionally, polyurethane foam provides sound insulation, minimizing noise transmission and creating quieter indoor environments.
2. Exterior Finish: The exterior surface of decorative metal siding panels is adorned with a variety of finishes, ranging from sleek metallic coatings to textured patterns and vibrant colors. This versatility allows architects and designers to achieve their desired aesthetic vision, whether it be modern and minimalist or ornate and intricate.
3. Panel Dimensions: Decorative PU wall sandwich panels come in a range of dimensions to suit different project requirements. Standard panel widths are 383mm and 400mm, with lengths customizable to fit specific building dimensions. The thickness of the panels can vary as well, with options typically ranging from 10mm to 25mm, providing flexibility in insulation and structural performance.
4. Lightweight Construction: Despite their robust insulation properties, decorative PU wall sandwich panels are remarkably lightweight. This characteristic facilitates easy handling and installation, reducing labor costs and construction time. The lightweight nature of the panels also places less stress on building structures, making them suitable for both new construction and retrofit projects.
5. Fire Resistance and Durability: Decorative PU wall sandwich panels are engineered to meet stringent fire safety standards, ensuring the protection of occupants and assets. Additionally, these panels are highly durable, capable of withstanding environmental factors such as moisture, UV exposure, and temperature fluctuations. This durability contributes to the longevity of buildings and reduces maintenance requirements over time.
In summary, decorative PU wall sandwich panels offer a combination of thermal insulation, aesthetic appeal, ease of installation, and durability, making them a versatile choice for a wide range of construction projects across residential, commercial, and industrial sectors.
