At Quanex Custom Components, sustainability drives every step of our hardwood processing. Through innovative technologies like finger joint wood production, we ensure that no piece of quality hardwood goes to waste, creating stronger, longer, and more cost-efficient components for our customers.
What is Finger Joint Wood?
Finger joint wood is made by joining shorter lengths of wood together using interlocking “fingers” and high-strength adhesives to create longer, stable boards. This process makes it possible to transform smaller, unused pieces of hardwood into strong, consistent materials suitable for a wide range of applications, like window and door jambs, trim mouldings, and custom millwork.
Because the finger joint process makes efficient use of residual wood, it’s one of the most sustainable and cost-effective ways to produce high-quality wood components.
Sustainability in Every Step
Quanex converts over 50 million board of hardwood lumber annually, with a commitment to using 100% of our hardwood residuals. Anything that doesn’t meet our high-quality standards, such as sawdust, knots, and short wood cuttings, is reused across our operations:
- Residuals fuel our kiln drying facilities, providing energy for moisture removal.
- Short cuttings are repurposed into finger joint wood boards.
- Remaining byproducts are sold locally for animal bedding, wood pellets, and erosion control.
By turning what would otherwise be waste into a valuable resource, we help you offer products that are both high-performing and environmentally responsible.
Benefits of Finger Joint Wood
Finger joing wood offers several advantages over solid hardwood:
- Cost Savings: Provides a lower-cost alternative without sacrificing strength or appearance.
- Sustainability: Maximizes the use of raw materials for minimal environmental waste.
- Durability: Engineered for stability and to reduce warping.
- Design Flexibility: Available in board lengths up to 24 feet for custom applications.
- Smooth Finish: Seamless appearance when painted, ideal for millwork and trim.
At Quanex, we combine innovation and craftsmanship to get the most out of every board. The finger joint process starts with shorter hardwood cuttings, which are carefully milled, joined with precise interlocking fingers, glued, and pressed together to form longer, continuous boards.
This process not only ensures structural integrity but also reduces overall waste, helping our customers deliver greener, cost-effective solutions with every project. See how we’re using innovation and efficiency to build stronger, more sustainable products.
