Gentek SteelTek Supreme Steel siding

Superior, Beauty, Durability and Protection

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.

SteelTek 12"BB

Impact Resistant

Constructed of roll-formed 29 gauge Galvalume AZ-50 steel for superior resistance to hail damage and denting

Smooth, Straight Wall Lines

Rigid steel panels deliver high dimensional stability and resist buckling and the wavy appearance that can result from expansion and contraction caused by extreme weather changes. The low thermal expansion of steel is less than 1/8" over a 12' panel for the anticipated temperature range.

Beautifully Uniform Finish

Tight joints keep overlaps neat and flat; rigid steel helps conceal imperfections in the exterior’s substructure.

Upscale Appearance

Deep 1/2" panel projection creates greater dimension and style with bold edges and dramatic shadow lines. The resilient finish resists dirt and dust buildup, staining and mildew.

Carefree Maintenance

No need for time-consuming painting or scraping. Just a simple rinse with a garden hose will remove most airborne dust and dirt to restore the like-new beauty.

Recyclable!

Steel siding is 100% recyclable, requires no additional painting or caulking and does not produce silica dust during installation.

Built Weather Tough

Steel siding also resists warping, chalking, fading and brittleness in cold weather; independently tested to withstand intense winds.

Simple to Install

Installs easily; unlike fiber cement, steel siding installation does not recommend a dust respirator or involve hazards from silica dust.

Class A Fire Rating

Unlike many other siding materials, steel is a non-combustible product, meeting even the most stringent building codes.

Insect Resistant

Resists damage from wood-eating insects, such as termites.

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

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.
