Advancements in the Manufacture of Architectural Metal Sheets
Modern Architecture Embraces Sustainable Metals for Durable and Aesthetic Construction
Contemporary architectural metals such as copper, zinc, stainless steel, and aluminum are playing a significant role in modern building projects, offering a unique blend of durability, sustainability, aesthetic flexibility, and climate resilience.
These metals are widely used in metal cladding, providing both protection and distinctive facades that improve insulation, water resistance, and long-lasting performance. The ability to customize these metals with different textures, patterns, and finishes allows for creative architectural expression without compromising structural integrity.
Copper, zinc, and their alloys (like brass and bronze) are particularly favored due to their excellent resistance to weathering and corrosion. Aluminum and stainless steel are prominent in structural and facade elements due to their high strength-to-weight ratios and adaptability. Aluminum sheet metal is especially favored in roofing, walls, supports, and duct fabrication for HVAC systems, given its excellent performance under different environmental conditions and thermal properties, which also improve energy efficiency.
As we move towards 2025, the focus is on using innovative alloys and coatings that enhance corrosion resistance, insulation, and thermal responsiveness, further improving metal's suitability for net-zero energy buildings and climate-resilient construction.
Heather & Little, a specialist in custom architectural sheet metal fabrication, is at the forefront of this trend. Their craftsmen have an understanding of metal properties, fabrication techniques, and traditional metalworking methods. They employ modern technology, such as laser cutting, robotic welding, CNC machining, and 3D modeling and BIM for accurate design and visualization, as tools to complement their skills, not replace them.
In historical restoration or replication, traditional methods and historical tools are used, and technology is employed only where it helps achieve a higher quality or more accurate outcome. This approach ensures that the integrity of historical buildings is preserved while still benefiting from the advantages of modern materials and techniques.
Metal surfaces require minimal maintenance, reducing costs, and metal roofs and cladding can help regulate temperature, offering energy efficiency. Metal flashing is used to prevent water infiltration, adding to the overall durability of the building.
Heather & Little also explores additive manufacturing and considers advanced materials and IoT for process optimization. They adopt sustainable practices, such as recycling, using energy-efficient equipment, and sourcing metals responsibly.
In summary, the contemporary architectural use of copper, zinc, stainless steel, and aluminum centers on combining aesthetic versatility, environmental sustainability, durability, and climate adaptation, making them essential materials in future-forward construction and design.
