Mahogany
Mahogany is an extremely dense lumber. It's interlocking grain prevents separation between annual growth rings, making it one of the most stable woods available.
It comes in clear grade only, no knots or sapwood. Colors range from a light tan to a deep auburn brown. Mahogany does not contain tannins, the wood will not stain when it comes into contact metal.
Performance Characteristics
Hardwoods like Mahogany naturally resist wear, rot and splintering. A very durable product for exterior use.
Lumber Grades
Boards are straight with virtually little or no knots or blemishes. Some boards may show signs of old insect boreholes approximately 1/8-inch or less in diameter or streaks of lighter colored wood grain.
Installation
Woods such as Mahogany should be drilled prior to nailing or screwing. The wood is so hard that without first drilling the wood, nails or screws will have a hard time penetrating it. You also risk the possibility of splitting the wood. Using screws rather than nails will alleviate problems such as nail heads popping up above the boards and prevent boards from loosening up over time.
Kiln dried Mahogany does not shrink but can swell slightly. Space 5/4x6 boards a full 1/4 inch apart. In wet climates, add 1/16 inch to your spacing.
Maintenance
Very little maintenance is required and a clear finish can be applied to preserve the natural color. If left unsealed, the wood will weather to a silver patina.
Safety Concerns
Relatively few safety concerns. When working with Mahogany or any other materials, use protective clothing, dust mask and eye protection. Wash clothes separately to avoid contact with other clothing.
Summary
Mahogany lumber is as hard as teak. It has the least amount of knots out of most other species of deck woods.
