Klauer Manufacturing Company, a provider of steel building products, announces that its steel siding has achieved a Class A fire rating certification following testing in accordance with ASTM E84-25 standards.
Steel siding has long been recognized as one of the most fire-resistant exterior cladding options available and has historically met fire code requirements in many residential and commercial applications. As wildfire concerns continue to grow and jurisdictions adopt more stringent resiliency standards — including portions of the Colorado Wildfire Resiliency Code taking effect June 1 — verified Class A rated materials are becoming increasingly important for builders, contractors, architects, and homeowners in fire-prone regions.
Klauer’s Class A rated steel siding provides a durable, low-maintenance exterior solution designed to support projects where enhanced fire performance and code compliance are priorities. Tested under ASTM E84-25 standards, the siding demonstrates minimal flame spread and smoke development characteristics associated with high-performing building materials.
In addition to fire resistance, Klauer steel siding offers long-term performance benefits including weather durability, low maintenance, and lasting curb appeal, making it a versatile solution for residential and light commercial exterior applications.
