The metal curtain wall represents an innovative architectural curtain wall solution. Its remarkable fabrication capabilities, varied color options, and robust safety features allow it to accommodate designs of intricate shapes. It supports processing diverse curves and lines, offering architects considerable creative freedom. This flexibility has significantly contributed to its rapid advancement in the field.

Diverse Categories of Metal Curtain Walls

Metal curtain walls can be categorized based on panel materials. These include color-coated steel, aluminum veneer, aluminum composite, honeycomb aluminum, anodic aluminum, titanium zinc, stainless steel, copper, and titanium panels. In terms of surface finishes, they are classified into glossy, matte, shaped, and corrugated metal curtain walls.

Color-Coated Steel Panels

These panels are manufactured using a continuous process involving cold-rolled or galvanized strips. After surface preparation, they are coated with one or several layers of liquid coating, then baked and cooled. Their aesthetic appeal, vibrant colors, strength, corrosion resistance, and ease of processing make them popular.

Aluminum Veneer

High-strength aluminum alloy is used to create aluminum veneer curtain walls. Available in various thicknesses, they are either bent and stamped directly or riveted for corner formation. Their enhanced strength ensures rigidity, wind and seismic resistance. They are ideal for exterior and interior walls, façades, column decoration, and more.

Aluminum Composite Panels

These panels consist of two 0.5 mm aluminum sheets with a polyethylene or PVC foam core. They are coated with fluorocarbon resin for durability and polyester paint to prevent corrosion. They are widely used in wall exteriors, renovation projects, and signage.

Aluminum Composite Panels

Aluminum Honeycomb Panels

Inspired by aviation industry technology, these panels use a honeycomb sandwich structure. They are composed of high-strength aluminum and can reach large dimensions without reinforcements. They offer excellent flatness and can withstand high pressures.

Anodic Aluminum Plates

These are created through an electrolytic process that forms a thin alumina layer on the surface. This process enhances hardness, wear resistance, heat resistance, and corrosion resistance. They are suitable for wear-resistant parts and come in various colors.

Anodic Aluminum Plates

Titanium Zinc Plates

Made from high-purity zinc with small amounts of titanium and copper, these plates exhibit natural corrosion resistance and a long lifespan. They blend well with other materials and maintain their integrity in harsh environments.

Stainless Steel Plates

Stainless steel plates, utilized in the realm of metal curtain walls, are available in a variety of finishes including mirror, matte, and titanium gold. These plates are renowned for their exceptional durability and resistance to wear, making them a long-lasting choice for architectural applications.

However, the article points out a couple of practical considerations when using stainless steel plates in curtain wall construction. If the plates are too thin, there is a risk of bulging, whereas excessively thick plates can be prohibitively heavy and expensive. As a result of these factors, the use of stainless steel in curtain walls is somewhat limited, often being employed more for localized decorative enhancements rather than as the primary material for the entire curtain wall.

This selective use allows for the integration of the unique aesthetic and functional properties of stainless steel without incurring the downsides of using it extensively.

Copper

Copper’s corrosion resistance makes it ideal for external walls and roofing. It’s historically used in Europe for roofing on churches and other buildings, with many ancient copper domes still in use.

Titanium Plates

Titanium plates are lightweight and exhibit unique properties like high melting point, good toughness, and excellent corrosion resistance. They retain their appearance over time, unlike other metals.

Metal Curtain Walls: Benefits and Challenges

Advantages

Lightweight Nature:Metal’s light weight significantly reduces the load on building structures and foundations, making it an ideal choice for the exterior decoration of high-rise buildings.

Outstanding Properties:Metal plates boast exceptional features including fire resistance, thermal insulation, soundproofing, waterproofing, stain resistance, and anti-corrosion capabilities.

Ease of Construction:From processing and transporting to installing and cleaning, metal plates simplify all related construction tasks.

Versatile Processing and Safety:With superior processing capabilities, a variety of colors, and robust safety, metal plates easily conform to complex design requirements, including diverse curves and lines, thereby expanding the creative possibilities for architects and curtain wall designers.

Adaptable Design:Metal can be tailored to meet specific aesthetic, performance, and functional needs, allowing for a broad range of decorative effects in metal curtain walls.

Cost-Effectiveness:Metal curtain walls offer high value for performance, requiring minimal maintenance and having a prolonged lifespan.

Challenges

Structural Calculation:It’s crucial to scientifically calculate the deformation resistance of the curtain wall system. This includes considering the impacts of wind pressure, weight, seismic activity, and temperature changes on the system, and meticulously inspecting embedded parts, the connection system, keel system, panels, and fasteners to guarantee safety.

Floating Connection:The use of floating connections is important to ensure the curtain wall’s ability to recover post-deformation and maintain its integrity.

Fading Issues:There is a propensity for the metal to fade over time.

Complex Projects:Projects with unique shapes demand high precision in the manufacturing process and may lead to extended construction timelines.
