Vertical Grain Fir for Gates

Strength and Durability

• Vertical grain fir resists warping, cupping and checking better than flat-grain wood. According to the Softwood Export Council, softwoods are lighter and more flexible than hardwoods, yet their long, tightly-packed fiber gives softwoods, especially Douglas fir, a high strength-to-weight ratio. Lumber made from Douglas fir is strong enough for roof trusses and durable enough for decks, fences and gates. Vertical grain fir resists weather damage and lasts longer than flat-grain lumber, and can be used in hurricane- and earthquake-prone areas. The boards used to make a vertical grain fir gate hold shape longer, requiring fewer repairs and other maintenance over the years, while the vertical grain adds beauty to the project.

Ease of Use

• The vertical grain fir's tight grain can make it difficult to cut. That same feature allows the wood to hold fasteners, such as nails and screws, better than flat-grain woods. This means that gates made with vertical grain fir will hold their latches, fasteners and hinges more firmly. This is a benefit for a gate that will be used regularly, since the gate will resist wobbling and screws that loosen inside the wood.

Finishing

• Although clear vertical fir, which generally has few to no knots, is more attractive, it is also expensive. Clear wood takes paint and stain smoothly. Lower grades of vertical fir has more knots, but if the gate is to have a rustic look, the knots provide interest and texture. Lower grades of vertical fir accept paint and stain well and the tight grain enhances the bond between the wood and the finish.

Cost and Availability

• Because of the way it is produced, vertical grain wood costs more than flat-grain wood. Douglas firs grow in the northwest, and importing the wood to distant states may add to the cost. The wood's ease of maintenance, durability and resistance to weather damage means the gate will last longer, and this alone may be enough for the homeowner to justify the initial higher cost.
