Enduring Beauty

For a virtually indestructible deck that will last a lifetime, RHINO DECK hardwood is a beautiful choice. With distinctive markings, a smooth, even texture, and warm highlights, it suggest the richness of teak - without the maintenance.

Five times harder than pine, cedar or redwood, RHINO DECK possesses natural, highly effective defenses against rotting, checking, cracking, splitting and decay. Uniquely durable, it resists the scarring and twisting that can happen to softer woods when exposed to the demands of everyday traffic and changing weather. In fact, this same hardwood species was the material of choice for the famous Atlantic City Boardwalk when it was rebuilt in 1981.

To add to its overall excellence, RHINO DECK is harvested using the most up-to-date, environmentally responsible sustained-yield forestry techniques.

Natural Durability

As mentioned, the species used for RHINO DECK is highly resistant to termites, decay, and mold. In fact, it earned the highest natural durability ranking (25 years plus) from the U.S. Agricultural Forest Products Research Lab, and is rated as fire-resistant as steel or concrete. With its natural oil resins, it’s impermeable to preservative solutions too – even when applied by pressure vacuum systems. If even pressure-treatment can’t make a dent on this wood, what else could?

Easy Maintenance

RHINO DECK should be equipped with a wood-stabilizing agent before it’s exposed to sunlight. Simply store any untreated pieces under a tarp, and apply the sunscreen during or after installation. We suggest using two coats of a high quality finish. For best results, reapply it annually, or as needed—and that’s all there is to it!

IPE Installation Instructions

Handling and Cutting
  Surfaced on 4 sides (S4S) and eased on 4 edges (E4E), RHINO DECK is ready for easy installation.
  Keep the product out of direct sunlight before installation and finishing.
  Ensure that there is proper ground-side ventilation before constructing your deck.
  Although RHINO DECK can be cut and machined with standard woodworking tools, for best results or large jobs, we recommend using a carbide-tipped blade.

Finishing and Maintenance
  Apply a high quality finish during installation, or immediately afterwards. We recommend Wolman Exotic Hardwood Treatment. If you plan to install your deck in stages, seal each section as you complete it.
  To maintain RHINO DECK’S natural beauty year after year, clean and reseal it annually.

  Stainless steel screws are recommended but not required. Screw length should be a minimum of 1 1/2” longer than thickness of the board.
  Pre-drill fastener pilot holes close to the actual screw diameter (decking board only).
  A minimum of 1/8” spacing required between decking boards.
  Decking boards should be attached with 2 screws at each joist (face screw only).

End Sealing
  After cross-cutting, the exposed ends should be sealed with a clear paraffin, wax-based end-sealant.

Janka side hardness is 3,060 lb.s for green material, and 3,680 lb.s for wood with 12% moisture content. The Forest Products Laboratory toughness average for green and dry material is 404”-lb.s (for a 5/8” specimen).

Dry and Shrinkage
This species is generally reported to air-dry rapidly, with only slight checking and warping. Some shrinkage may occur after installation.

Working Properties
The wood is moderately difficult to work (especially with hand tools), and will blunt cutting edges. It finishes smoothly except where grain is mixed.

The heartwood is very resistant against decay, fungi, and termites; it is not resistant to marine borers.

The wood is reported to be extremely resistant to preservation treatments.

This hardwood is used for railroad crossties, heavy construction, tool handles, industrial flooring, decorative veneers, and residential use.

About Rhino Deck IPE
(Tabebuia ssp)

click to enlarge

This species is distributed widely – from Colombia to Bolivia, across the Guianas, and throughout southeastern Brazil. Described as ecologically diverse (especially in the Brazilian Mata Atlantica), it tends to grow in more or less seasonal forests on the well-drained lateritic soils of the Amazons. However, it can also be found on rich or sandy soils, even into the cerrado in sub-Amazonian Brazil. As for elevation, in most cases the tree situates itself from near sea level up to 3940 ft. (1200 m).

Botanical Information

Other Common Names
Arnapa, IPE, Iron Wood, Pau Lope (Mexico), Cortez (Honduras, Nicaragua, Costa Rica), Guayacan (Panama), Guayacan Polvillo (Colombia).

The Tree
The tree can grow as tall as 140 to 150 ft., with a trunk diameter of 6 ft. Most frequently, it reaches 100 ft. in height, with a 2 to 3 ft. diameter.

The Wood
In general, the hardwood is olive-brown to blackish, often showing a lighter or darker striping. Frequently it’s covered with a yellow powder sharply defined from the whitish or yellowish sapwood. Its texture is fine to medium; its luster, low to medium; and its grain, straight to very irregular. The wood is rather oily looking, without any distinctive odor or taste.

Basic specific gravity (oven dry weight/green volume) 0.85 to 0.97; air-dry density 66 to 75 pcf.
