Humboldt Sawmill redwood decking is one of nature’s finest and strongest building materials with shear strength up to five times greater than plastic and composite decking. All this strength and durability comes packaged in a lightweight wood that’s easy to work with, which helps lower overall construction costs. No other decking material mimics the natural beauty, durability, strength, and warmth found in real redwood deck boards and accessories.
On top of these benefits, Humboldt Sawmill redwood decking is beautiful. It’s rich, warm color and grain pattern look great even with age. Redwood decking also features Class B flame spread and is approved for use in California’s Wildland Urban Interface (WUI) fire hazard severity zones without restriction.

For those concerned about the environment or those with a preference for all-natural materials, Humboldt Sawmill redwood is the obvious choice. Manufactured from Forest Stewardship Council (FSC C013133) certified, 100% natural materials, Humboldt Sawmill redwood decking is a renewable resource that is non-toxic and safe for children and pets.

Humboldt Sawmill Redwood Class A Exterior Decking Products
In order to offer our customers a Class A flame-spread rated product, Humboldt Sawmill works with Chemco, Inc. of Ferndale, Washington to pressure treat Superior Common decking with Thermex-FR®, an exterior fire retardant. The result is Humboldt Sawmill Redwood Class A Exterior Decking Products. The product is covered by a Limited Lifetime Warranty. In addition to decking, accessory items such as joists, railings, and other specialty items are available. A product brochure may be downloaded as well.
Class A flame-spread rating means this product can be used under even the most stringent Wildland-Urban Interface (WUI) building codes throughout the country, including the International Code Council® International Wildland-Urban Interface Code (IWUIC). The IWUIC code requires decks to be constructed of approved fire retardant treated wood specified for exterior use. Under such guidelines, only a Class A flame-spread rated exterior wood product would qualify for usage.
