• Proven performance under extreme conditions

Durability

Very resistant to decay, insects and fungal attack, even in tropical environments.

Resistant to abrasion, wear and dents. Naturally fire resistant.

Ease Of Maintenance

Easy to maintain! Accepts standard penetrating oil finishes to maintain that rich dark “Mahogany look” or leave unsealed to weather silver gray patina.

6. KEMPAS.

 

Kempas Origin: Kempas originates from Malaysia and Indonesia.

Common Name(s): Kempas

Botanical Name: Koompassia malaccensis

Woodworking Qualities: Hard deposits within Kempas can provide for problems during woodworking or sawing. Pre-boring is highly recommended to set nails or screws, but once the nails are in, this wood holds them well. Gluing is also a viable option, as adhesive substance works well. Sanding is usually not a problem, although some filling can be required when polishing.

Janka Rating: Kempas Janka rating is 1710, relatively high compared to many other woods.

Species Characteristics: Kempas has a reputation of being acidic, which can cause damage to metals when wet. Drying is not particularly hard unless the wood itself has abnormalities. In addition, Kempas is resistant to decay.

Appearance: Kempas’ grain features an interlocked pattern that can sometimes vary to spirals. Sapwood is white to a pale yellow and heartwood is orange-red to red-brown.

Color Change: Kempas’ color change compared to other flooring is relatively minor, showing only a slight change from an already red or pink-toned brown to darker red brown.

Uses: Railroad ties, furniture, veneer, and cabinetry are all uses for Kempas in addition to hardwood flooring.

7. KERUING (Dipterocarpus)

Keruing is an imported hardwood

Location

Keruing or apitong (Dipterocarpus) is widely scattered throughout the Indo-Malaysian region. Most of the more than 70 species in this genus are marketed under the name keruing. Other important species are marketed as apitong in the Philippine Islands and yang in Thailand.

Characteristics

  

The heartwood varies from light to dark red-brown or brown to dark brown, sometimes with a purple tint; the heartwood is usually well defined from the gray or buff-colored sapwood. Similar to kapur (Dryobalanops), the texture of keruing is moderately coarse and the grain is straight or shallowly interlocked. The wood is strong, hard, and heavy (density of air-dried wood is 720 to 800 kg/m3 (45 to 50 lb/ft3)); this wood is characterized by the presence of resin ducts, which occur singly or in short arcs as seen on endgrain surfaces. This resinous condition and the presence of silica can present troublesome problems. Sapwood and heartwood are moderately resistant to preservative treatments. However, the wood should be treated with preservatives when it is used in contact with the ground. Durability varies with species, but the wood is generally classified as moderately durable. Keruing generally takes to sawing and machining, particularly when green, but saws and cutters dull easily as a result of high silica content in the wood. Resin adheres to machinery and tools and may be troublesome. Also, resin may cause gluing and finishing difficulties.

Primary Uses

Keruing is used for general construction work, framework for boats, flooring, pallets, chemical processing equipment, veneer and plywood, railroad crossties (if treated), truck floors, and boardwalks.

9. MERANTI  ( Shorea spp ).

Family – Dipterocarpaceae

Meranti is a common name applied commercially to four groups of species from the genus Shorea, grown most commonly in Malaysia, Indonesia, and the Philippines. There are thousands of common names for various species from the genus Shorea. The four groups are “light red”, “dark red”, “yellow”, and “white”. I will put in more information at some point.

listed as “bakau” meranti, whatever that is.           dark red

 
light red                           Medium Red Meranti

 
“light white”/orange    yellow Meranti

In the Philippines, as well as elsewhere in their range, Shorea trees might be called red or white lauan, tangile, almon, as well as the descriptive “dark-red meranti” or “light-red meranti.” But it is meranti (Shorea spp.) that makes up the greatest proportion of timber that’s sold as Philippine mahogany. (Note: In botanical science, the letters spp. after the genus name means that several species in that genus share similar appearance and characteristics, e.g. Shorea spp.) Meranti traditionally grows in well-drained soils at low altitudes. In ideal conditions, a meranti tree can reach a 200′ height and a trunk diameter of 6′. A lumberman’s dream, it will also be branch free for 90′. The bases of some trees feature the vanelike supports called buttresses. Light-red and dark-red meranti produce medium-to-coarse textured wood that ranges in color from pale pink to brown and reddish-brown. The grain may be slightly interlocked. At about 36 pounds per cubic foot air-dry, meranti is heavier than Honduras mahogany. However, it is not nearly as hard nor as strong, and lacks the durability and stability of a true mahogany. And you may find brittleness in some boards.

Other Names : Red Meranti, Seraya merah, Shorea acuminata / leprosula / parvifolia / macoptera / ovalis / dasyphylla / lepidota / palembanica / teysmanniana / platycarpa / albida / quadrinervis / leptoclados / smithiana.

Characteristics : Red Meranti ( Seraya ) has a light coloured sapwood and red-brown to dark red heartwood. The texture is rather course but even, the grain interlocked and wavy. Red meranti weighs an average of 550 Kg / m3 when dried,

Working Qualities : The wood of the various species work well and in general are capable of a good smooth finish. Meranti can be glued, nailed and screwed satisfactorily, and can be stained and polished well after suitable filling.Uses : All the merantis are suited to joinery and general construction, and also for furniture.

10. RADIATA PINE.

Radiata Pine is a versatile timber; it is widely used for the full range of structural and decorative applications including framing, lining, glue laminated beams, veneer and plywood. When appropriately treated, it can be used for many exposed structural and non-structural applications.

The timber is low in density and fairly soft, often with very wide annual growth rings. The heartwood is light brown to yellow; the sapwood white to pale yellow, but often indistinct. The grain is usually straight, but knots are common.

Radiata Pine is very easy to work with standard tools, although its knotty character and resin canals can cause premature blunting of cutters. Its open grain structure readily accepts preservative treatment, which can provide protection to hazard level 6 (the highest level).

Radiata Pine is a plantation softwood timber grown widely throughout Australia. In Tasmania the first commercial Radiata Pine plantations were established in the 1930s. Since then the Tasmanian Radiata Pine estate has expanded to more than 55,000ha, largely concentrated in the north-east of the State. The tree has also been widely planted in windbreaks and as stock shelter, particularly on slopes of otherwise poor productivity.

Radiata Pine plays a significant role in meeting the ever-increasing demand for sawn timber. As a well-managed plantation tree, it can provide a renewable resource providing dependable supply for generations to come.
