Supreme Steel Siding

SteelTek Siding
Pounding rain, severe wind, freezing cold and blistering heat are no match for the commanding strength of steel.  Each pretreated galvanized steel panel is virtually “weather-sealed” with a resilient Kynar PVDF finish, ensuring long-lasting beauty and protection.

Impact Resistant: Constructed of roll-formed 29 gauge Galvalume AZ-50 steel for maximum resistance to hail damage and denting.

Straight Wall Lines: The low thermal expansion is less than 1/8″ over a 12′ panel for high dimensional stability.

Upscale Appearance: Deep 1/2″ panel projection creates greater dimension and style.  The PVDF coating system resists dirt buildup, staining and mildew.

Class A Fire Rating: Unlike many other siding materials, SteelTek Supreme steel siding is a non-combustible product, meeting even the most stringent building codes.

Built Weather-Tough: Unlike wood, compressed particleboard or fiber cement, SteelTek Supreme won’t absorb moisture.  Steel siding also resists warping, chalking, fading and brittleness and is independently tested to withstand hurricane-force winds exceeding 160 mph.

Environmentally Friendly: SteelTek Supreme steel siding is 100% recyclable; no painting, caulking or issues with silica dust.

Insect Resistant:  Resists damage from wood-eating insects.

Simple to Install: Installs easily; unlike fiber cement, SteelTek Supreme steel siding does not involve hazards from silica dust.
