Metal Building Materials 101: Understanding the Basics

Welcome to Custom Curb, Inc.’s guide to metal building materials. Whether you’re new to the world of construction or just curious about metal buildings, this post will introduce you to the key terms and concepts you need to know.

1. Types of Metal Used in Buildings

  • Steel: This metal is most commonly used metal in building construction, known for its strength, durability, and versatility. It’s often used in structural frames, roofing, and wall cladding.
  • Aluminum: Lightweight yet strong, aluminum is used for roofing, flashing, and sometimes in structural applications. Its resistance to corrosion makes it ideal for harsh weather conditions.
  • Copper: Although more expensive, cooper is prized for its longevity and distinctive appearance. It’s primarily used for decorative elements and roofing.

2. Metal Building Components

  • Structural Framework: The skeleton of a metal building, usually made of steel, provides the primary support structure.
  • Roofing and Wall Panels: These elements are the visible exteriors of metal buildings. They can be made from various metals, depending on the required aesthetic and functionality.
  • Roof Walks: These designated walkways are often made of metal or other durable materials, installed on rooftops to provide safe, stable paths for maintenance or inspection purposes.
  • Skylights: These windows are installed in the roofs of buildings to allow natural light to enter, enhancing interior illumination and potentially improving energy efficiency.
  • Insulation: Vital for energy efficiency, insulation in metal buildings is typically made from fiberglass, foam, or reflective materials.
  • Fasteners and Connectors: These pieces include bolts, screws, and rivets, crucial for assembling and securing different parts of the building.
  • Wall Louvers: These features are used in buildings to facilitate air flow while protecting the interior from external elements like rain and debris.


3. Metal Coatings and Finishes

  • Galvanization: A process where steel is coated with a layer of zinc to prevent rust.
  • Powder Coating: A type of coating applied as a free-flowing, dry powder, often used for a more durable and high-quality finish.
  • Anodizing: Used mainly for aluminum, this electrochemical process increases corrosion resistance and can add color.

4. Advantages of Metal Buildings

  • Durability: Metal buildings are resistant to many environmental factors like wind, fire, and pests.
  • Sustainability: Many metals are recyclable, making metal buildings a more eco-friendly option.
  • Cost-Effectiveness: Over time, metal buildings can be more cost-effective due to their low maintenance and longevity.

5. Common Uses of Metal Buildings

  • Industrial and Commercial: Warehouses, factories, and retail stores.
  • Residential: Steel framing for houses, garages, and storage sheds.
  • Agricultural: Barns and storage facilities for equipment and livestock.
