Metal through the eras: A building material made to last

By Metal Central.

Get a glimpse at the history of metal building materials and how they have evolved into a sustainable solution for the modern age.

As metal roofing has continued to gain popularity in recent years, it's important to recognize the important role the material has played throughout history. Long before metal’s sustainability and aesthetic appeal of today, the material was used in rudimentary ways, refined over the ages to become the reliable resource of the 21st century. As industries and technologies evolve, one thing remains constant: the reliability and versatility of metal. It continues to be a top choice for construction projects, and for good reads. Metal Central shares a closer look at the historical significance and humble beginnings of this revolutionary building material.

Metals have historical roots

Lead and copper

These metals played significant roles in architecture for thousands of years. Lead, with its low melting point, was easily formed to create watertight roofs. Copper, too, was widely used, with examples like the copper roof shingles atop the Lovamahapaya Temple in Sri Lanka dating back to the 3rd century BCE. The Romans even covered the Pantheon with copper in 27 BCE!

Iron and terne

As iron smelting became widespread in the 19th century, iron sheets were coated with molten tin or zinc to prevent rust. Terne, an iron plate dipped in a lead-tin solder, gained popularity for roofs and weather-resistant farm items.

Corrugated Galvanized Iron (CGI)

In 1829, corrugated galvanized iron emerged as a favorite roofing material worldwide. Its strength and lightweight nature made it a game-changer.

Now let’s compare those ancient metals with today’s manufactured metal panels for roofing and siding from Central States. Oh, how far we’ve come!

Metal roofing today: sustainability and environmental consciousness

Recyclability

Metal roofing systems are made from a high percentage of recycled materials. At the end of their extended life cycle (which can be up to 60 years or more), metal panels can be 100% recycled. Unlike asphalt shingles, which end up in landfills, metal roofs rarely contribute to waste.

Weight and shipping efficiency

Metal panels weigh less than half of asphalt shingles, making them easy to transport and to carry up a roof. Their lower weight may allow the building structure to be lighter and use fewer materials. Additionally, metal panels can often be installed over existing roofs, reducing the need for removal and landfill disposal.

Longevity

Metal roofing lasts two to three times longer than traditional asphalt roofs. Its durability means fewer repair and replacement possibilities, reducing overall environmental impact.

Coating technology

Modern metal roof and siding panels incorporate advanced coating technology. Features like solar reflectance and heat emittance drive down energy use and allow buildings to work harmoniously with the environment.

Repurposing and reuse

Metal panels are long-lasting and can be repurposed or reused. Their versatility ensures that they don’t end up as waste but continue to serve a purpose.
