SteelTek Supreme
Steel Siding

Product Features

Two of the world’s best performing materials come together in SteelTek Supreme steel siding. This heavy-duty Galvalume® AZ-50 steel with Kynar® PVDF coating technology delivers on every promise for enduring beauty, impressive strength, uniform quality and a markedly refined appearance for your home.

Powerful Galvalume AZ-50 Steel At the core of SteelTek Supreme’s impressive performance is Galvalume AZ-50 steel. Galvalume features a specially formulated 55% aluminum-zinc alloy coating that protects the steel from the elements and provides superior corrosion resistance compared to conventional galvanized steel.

High Performance Yield Strength

Yield strength is the amount of stress a material can withstand and is measured in thousands of pounds of force per square inch (KSI). SteelTek Supreme’s yield strength has been tested and proven to perform with impressive results.

•  Yield Strength is the force (tension, compression or shearing) that is applied to a material and results in some type of material deformity; the material does not fail and it may return to its normal shape when the force is removed. SteelTek Supreme YS is 35,000 pounds per square inch.

Superior, Beauty, Durability and Protection

Resilient Kynar PVDF Coating System

The power of Kynar PVDF stands clear in its superior resistance to the challenges of nature and time. Protecting and preserving the steel core, the resilient fluoropolymer resin provides a luxurious, low-gloss color that resists scratches, fading, chalking, pitting, chipping and more. SteelTek Supreme’s proprietary coating is also specially formulated for enhanced texture.

•  Highly durable and weatherable
• Fluorinated polymer pigments keep colors true and help prevent fading
• Beautiful, strong, low-gloss finish with superior scratch resistance
• High-performance coating protects panels from staining and helps prevent dirt and other airborne pollutants from adhering to the siding
• Resists mildew and fungus growth – Kynar does not have UV-sensitive organic material needed for mildew growth

For Your Careful Consideration

When selecting the best exterior cladding for your home, it’s important to understand the facts. Fiber cement often gains attention for its appearance of freshly painted wood, but when you compare it side by side with steel siding, you’ll see why SteelTek Supreme is an excellent choice.

The Dangers of Silica Dust

Silica-based fiber cement contains respirable crystalline silica, which is considered by NIOSH (National Institute for Occupational Safety and Health) to be a cause of cancer from some occupational sources. Breathing excessive amounts of respirable silica dust can cause a disabling and potentially fatal lung disease, such as silicosis.² During installation, a dust-collection system attached to a mechanical saw or high-speed cutting tool is recommended, or wear a NIOSH-approved dust mask or respirator. Recommended cleanup includes a vacuum and filter appropriate for capturing respirable silica dust or wet cleanup method to further prevent exposure. Do not dry sweep.

Did You Know?

• SteelTek Supreme’s Kynar PVDF coating system has a performance additive that results in improved scuff resistance over polyvinyl chloride (PVC) finishes.
• Steel siding can now be cut with an approved saw blade, making installation faster and easier.
• Because steel siding is “hung,” it floats better on the exterior for a smoother appearance; fiber cement installs tightly to the exterior wall and thus can show unevenness or imperfections in the substructure.

Better Products for a Better Future

You may not realize it, but building green begins long before the materials are ready for installation on your home. It begins with a strong commitment to “source reduction” by the manufacturer. This means that all aspects of production are designed to help reduce the volume and environmental impact of waste, while also ensuring thoughtful material use to create products with a longer service life. At Gentek, we strongly encourage best practices for environmental stewardship and proudly offer a wide variety of recyclable steel, aluminum and
vinyl products.

Built to shield your home from even the most punishing weather, Gentek steel siding also promotes energy conservation by creating a tight building envelope for more efficient heating and cooling performance year-round.³ In terms of strength and stability, steel offers many advantages for residential home building – and has long been North America’s most recycled material!⁴ The uncompromising endurance of this heavy-gauge siding promises exceptional beauty and lasting protection for your home.

A Lifetime of Protection

SteelTek Supreme steel siding is backed by a lifetime limited, non-prorated, transferable warranty with 50 year hail and 35 year chalk and color change protection.
