A roof is an investment with long-term potential and selecting the appropriate metal coil plays a critical role in its long-term performance. East Lake Metals is pleased to offer guidance to assist you in selecting a metal coil that best meets the specific requirements of your roofing project, helping you making informed decisions with regard to material, finish, and durability.

Selecting an Appropriate Metal Coil for Roofing Projects

    1. Material Matters. Your choice of metal coil can have a considerable effect on its overall performance. East Lake Metals offers several steel and aluminum options, so understanding their characteristics is critical to making the right choice for your project. 
      • Steel is widely acknowledged for its strength and durability, making it the go-to material in projects where robust structural support is key. Thanks to its resistance against impact and weathering, steel coils offer longevity and reliability – perfect for commercial and industrial roofing applications.
      • Aluminum is lightweight and corrosion-resistant – two qualities which make it an excellent choice for residential or commercial roofing projects in coastal regions where humidity and saltwater may be factors. The modern appearance of aluminum adds an aesthetic flair that complements roofing projects beautifully.
  • When durability meets coastal resilience, Armored Coast stands as the reliable solution for those seeking a roof that doesn’t just weather the storm but triumphs over it.  Armored Coast is crafted from steel coated with ZAM technology, a groundbreaking fusion of zinc, aluminum, and magnesium. Armored Coast offers a robust shield against corrosion, providing coastal property owners with peace of mind.
  1. Finish Options.  East Lake Metals offers both pre-painted and mill finishes for metal coils – each offering unique benefits and distinct advantages. 
    • Pre-Painted Coils.  With an assortment of colors and finishes to meet your aesthetic preferences, pre-painted coils offer many design opportunities. Their durable coating not only adds visual appeal but also acts as a protective shield against corrosion and UV radiation rays – making pre-painted coils an excellent option for projects where customization and aesthetics are top priority.
    • Mill Finish Coils.  Mill finish coils provide a natural appearance, making them ideal for projects requiring a rustic or industrial aesthetic. They’re also an economical solution that often fits better with projects focused on functionality rather than intricate design.

Considerations for Different Roof Projects

    1. Commercial Roofing.  Commercial roofing projects often demand the optimal combination of strength and durability coupled with an aesthetically pleasing finish. Steel coils, particularly pre-painted for added aesthetics, are recommended as suitable roofing options for commercial buildings.
    2. Residential Roofing. Metal roofing stands out from traditional tiles as an exceptional residential option.  Aluminum offers lightweight protection that’s also corrosion-resistant and coils with pre-painted finishes provide the ideal combination of functionality and visual appeal, while their lightweight nature enables easy installation. 
  • Industrial Roofing. Steel coils are an unmatched material choice for industrial roofing projects, offering unsurpassed structural integrity to withstand the harsh conditions found within industrial environments. Steel is also known for its incredible durability – requiring little maintenance even during heavy duty settings.

How to Select the Appropriate Metal Coil: A Step-by-Step Guide

Step 1: Assess Project Requirements. Consider environmental, structural, and aesthetic preferences before selecting materials.

Step 2: Consider Budget Constraints. While quality should always come first, budget constraints also must be considered carefully when making purchasing decisions. Mill finish coils may provide the ideal cost-cutting solution for projects with tight financial restraints.

Step 3: Choose Materials.  When choosing the best material for your project, consider your specific needs. If strength and durability are paramount, steel makes an excellent choice, particularly for industrial and commercial applications. On the other hand, choose aluminum for residential projects or coastal areas, where its lightweight nature and corrosion resistance offer a perfect blend of aesthetics and functionality.

Step 4: Decide on Finish Options.  For a polished and customized appearance, opt for pre-painted coils – their vast array of color choices and finishes easily harmonize with your architectural vision. Conversely, the use of mill finish coils imparts a natural, untreated aesthetic, offering a rustic or industrial charm that can complement a range of design styles.

Step 5: Consider Long-Term Maintenance Needs.  Consider the long-term maintenance needs of the material you choose, ensuring they align with your project’s sustainability goals and budget considerations. 

Step 6: Environmental Considerations.  Take into account the environment surrounding your site when choosing metal coil for your project.  In areas with coastal conditions or high humidity levels, corrosion resistance becomes particularly crucial.

How to choose the paint for aluminum coils? - Knowledge - Hanchen

The right coating is crucial to extend the service life of color-coated aluminum coils. Choosing the most suitable coating material requires comprehensive consideration of the application environment, design requirements, and other aspects. Here are some factors to consider when making your selection:

Application conditions: The first thing to consider is how the aluminum coils will be used and where they will be installed. Will they be used for outdoor or indoor applications? Will they be exposed to extreme weather conditions or chemicals? This information will help you choose a paint that can withstand the conditions in which it will be used.

Type of coating: There are various types of coatings available for aluminum coils, including polyester (PE), polyvinylidene fluoride (PVDF), and silicone-modified polyester (SMP). Each type has its own set of strengths and weaknesses. For instance, PVDF coatings are known for their exceptional durability, but they can be quite expensive. On the other hand, polyester coatings are more affordable, but are not as durable as PVDF coatings.

Color and gloss: Consider the color and gloss of the paint you want to use. Different coatings come in a variety of colors and gloss levels. If you're looking for a specific color, make sure that the paint you choose can be custom tinted to match.

Warranty: Look into the warranty offered by the paint manufacturer. A good warranty will ensure that the coating will last for a long time without chipping, fading, or deteriorating.
