Ensuring Years of Beauty with the Finest Materials

Alpha offers various types of metals, each offering distinct characteristics in terms of appearance, durability, and corrosion resistance. The choice of metal depends on the specific requirements of the project, living near the beach in San Diego for example, the salt water in the air affects the metal in and around your home. Our professionals can help you find the perfect metal to compliment your homes curb appeal and keep it protected.

Coated Metals

The practice of coating metal with zinc for siding and roofing originated in the early 19th century with the invention of galvanization. Over time, advancements in galvanization technology have led to improvements in coating quality, application methods, and environmental sustainability. With the incorporation of a Kynar coating, an additional layer of protection is imparted to the material, enhancing its resilience against environmental elements while concurrently reflecting solar radiation.

Galvalume® / zincalume®

A revolutionary metallic-coated steel, providing unparalleled durability and corrosion resistance with its optimized 55% AluminumZinc coating. This coating ensures a service life of up to 60 years in exterior applications, four times longer than standard galvanization.

Upon being cut, the zinc/aluminum alloy coating of ZINCALUME® steel effectively seals the bare steel at the cut edge. This process furnishes galvanic protection to cut or scratched areas of exposed bare steel.

Aluminum, Bonderized & Coated Steel

These metals are widely favored substrates for roofing and wall cladding due to their exceptional economic viability. Aluminum, prized for its lightweight nature and ease of handling, presents a practical choice. Meanwhile, bonderized steel, also referred to as paint grip steel, undergoes a meticulous phosphate bath process to ensure optimal adhesion of coatings. Alpha Metal Systems provides these metals in a variety of gauges and coatings to cater to diverse project requirements.

Weathering Metals

Materials that improve in appearance as it weathers due to oxidation are often called weathering metals. Exposure to air and moisture creates a protective patina, showcasing a range of colors like green and blue, enhancing the metal’s aesthetic appeal. While certain specialized materials may have environmental limitations, be assured that our seasoned professionals will work with you to find the optimal aesthetic and metal for your project.

COPPER

The premier choice for marine corrosion resistance in metal roofing, prized for its unparalleled durability and longevity. Copper’s timeless beauty and exceptional durability make it an ideal option for any project, ensuring enduring quality for generations. Evidence of copper’s longevity is widespread across Coronado Island, showcasing roofs and gutters that maintain pristine condition even after centuries of service. Additionally, copper’s natural patina process, transitioning from dark brown to distinguished green, serves as a protective layer, enhancing both its aesthetic and value over time.

Zincalume plus™

A clear odorless resin coating is applied in-line to Zincalume® steel, this resin coating provides a beautiful finish while also meeting the handling and safety needs of roll-formers, service centers and installers.

Over 12-18 months, the surface finish darkens as the resin coating weathers away, preserving durability without powdering, peeling, or cracking. This change solely affects the visual aspect, with no compromise to protective properties, weathering like nonresin-coated Zincalume®.

RUSTeel plus™

An ideal design option for that classic, historic, weathered look. It quickly and naturally forms a layer of rust or patina when exposed to various atmospheric and weather conditions. The attractive aged appearance of Rusteel Plus™ often blends delightfully with the surrounding natural environment. Its appearance develops and changes with time.

Rusteel Plus™ (A606-4) is best suited for dryer, less humid environments and is not recommended for marine environments.

Premium Finish

Premium finishes are one of a kind in the coating process has a color range. Color can vary from batch-to-batch and have directional variations. Due to color ranges, color matching of this product is not available.

Vintage®

An innovative coating process over a G-90 metallic-coated steel surface. The process creates shade variations from light to dark, the lighter shade exhibiting a grey tone while the darker shade exhibits a bronze or brown tone. The dynamic, pre-aged appearance makes this a beautiful and durable product choice that is also graffiti resistant.

This versatile finish is widely favored for standing seam profiles, flat concealed fastener wall panels, or when combined with wood and stone elements.
