Ipe Decking

World-renowned quality. The only thing they don’t gamble on in Atlantic City is the wood they use to rebuild the Boardwalk. When engineers had the chance to pick any hardwood in the world for the Atlantic City Boardwalk, they chose Iron Woods® Ipe Decking. Since 1971, Iron Woods® has supplied virtually every deck board used in the reconstruction of the world’s most famous boardwalk. More recently, Iron Woods® brand Ipe was used in the post-Hurricane Sandy reconstruction up and down the east coast of the United States. So why has original Iron Woods® brand Ipe been considered the best of the best in decking products for both commercial and residential deck construction for over 40 years?

Unrivaled strength. Unparalleled beauty. Iron Woods® Ipe Decking can be left to weather naturally to an attractive silver grey and requires only the occasional cleaning. Alternatively, one can choose to maintain the wood’s natural rich brown color by cleaning and refinishing as required; not unlike polishing your favorite piece of furniture. Unlike composite decking, Iron Woods® Ipe Decking can always be restored to its original appearance because the wood’s natural beauty runs through and through.

#1 rated by the world’s leading consumer magazine. Iron Woods® Ipe Decking stands up to the elements year-round – from the heat and humidity of Central Florida to the four seasons of the Mid-Atlantic and Northeast, complete with Atlantic Ocean spray, brutal winters and hot summers. No matter where you live, no matter what the application, Iron Woods® Ipe Decking is the trusted choice of professionals and the right choice for your home or business. Whether it’s 5 miles of boardwalk on Long Island or 1,000 square feet in your back yard, there is no job too big or too small for Iron Woods® Ipe Decking.

The difference is in the grade.

Ipe, like any other species of wood, is produced to different gradeband quality standards. In the absence of official grading rules for hardwood decking, Iron Woods® set its own standards over 50 years ago. Consumers, Architects and Building professionals recognize the Iron Woods Premium Select Architectural Grade as the benchmark for quality and consistency.

Iron Woods® Ipe Residential Deck Installation & Maintenance


Iron Woods® Ipe decking is supplied as partially dried or kiln dried lumber. Store the wood out of direct sunlight and allow the wood to acclimate and stabilize to the installation area’s humidity before installing. Some air-dried boards may show marks from sticker or breather strips. Generally these marks and water marks blend in when the sealer is applied. If still visible, they will dissipate during the next year as the deck fades. We recommend carbide-tipped saw blades and high-quality drills for smooth cuts.


These spans are designed for Ipe to allow for minimal deflection of the deck surface. For maximum spans and engineering data, you can contact us.



Load Size
Board Size 40psf 60psf 100psf
1×4, 1×6 32″ 28″ 24″
5/4×4, 5/4×6 42″ 38″ 32″
2×4, 2×6, 2×8 62″ 56″ 48″

Allow a 1/8″ gap between deck boards for drainage and airflow. End-to-end butt joints are installed without a gap. Decking may shrink approximately 1/16″ on 4″ wide and 1/8″ on 6″ wide decking. In hot or dry areas you may experience additional shrinkage. End-to-end butt joints should be installed without a gap.

Adequate ventilation of the deck is essential for long-term stability and to minimize cupping. Proper air ventilation allows air to flow in from outside the deck area, under the joists and up through the gaps between the deck boards.

For screws, we recommend the high-quality, stainless steel “self-drilling” type. Though coated screws may also be used, using lower quality fasteners can cause black staining. To install Iron Woods® Ipe, you must pre-drill a pilot hole and countersink to avoid splitting, even when using self-drilling screws, and then fasten with high quality stainless steel trim head screws, which are available at Iron Woods® dealers.

Be sure to seal all ends immediately after cutting with Anchorseal clear wax end sealer (available from your Iron Woods® dealer) in order to reduce end checking. To maintain a rich walnut color, use a transparent penetrating oil-based sealer with UV inhibitors in a trans-oxide pigmented “tone” and reapply annually or as needed. If you prefer a silvery-gray appearance, use a clear oil-based sealer for the first coat and then simply let the wood weather to its natural gray color. If you want to return silver-gray wood to the original color, use a “wood brightener.” Careful power washing and/or sanding can help to remove the grayed wood.
