Mangaris Gold

Mangaris® Gold Decking

Mangaris® Gold is produced from a genuine Gold Balau species which is hard, clear grade, tight and interlocked grain wood with consistent color. The texture is deep Gold with minor amount of fine brown ribbon stripes.

  • Keep your MANGARIS® boards clean, dry and out of direct sunlight before installation and
  • Allow the material to acclimate and stabilize to the local climate (4-7 days) prior to installation.
  • More time required to acclimate in hot/dry climates. (7 – 14 days)
  • To Avoid Metallic Particle Corrosion Contamination, Do Not Cut Metal anywhere near the deck
    boards during and after installation.
Board Size Load (On Center Spacing)
40 psf 60 psf 100 psf Recommend
1×4, 1×6 32″ 28″ 24″ 16″
5/4×6 42″ 38″ 32″ 24″

Note: Please make sure you are following local building codes regulation.

  • Allow adequate ventilation for proper air flow to reduce cupping potential. (See diagram)
  • Minimum recommended ground clearance:
    a. 5/4×6 and 1×6 Regular Boards are 24” or 18” with vapor barrier and a slope drainage
    system to avoid standing water.
    b. 1×4 and 5/4×4 Regular Boards are 18” or 12” with vapor barrier and a slope drainage
    system to avoid standing water
  • Reduce moisture “wicking”. Seal all fresh cuts with Anchor Seal (liquid paraffin wax) available
    from Lumber Dealer.
  • We recommend finishing MANGARIS® with deep penetrating oil based and have ultraviolet
    inhibitors, on all four sides.
  • A Periodic cleaning and a light coat of finish will be required in order to maintain the original
    color of your deck or allow weathering to a silver-grey look. Consult your dealer regarding a
    finish product prior to re finishing your deck.
  • MANGARIS® deck boards are kiln dried. Unlike air dried boards, shrinkage is very limited;
    however, excessive moisture may cause the boards to expand slightly.
  • Recommended spacing is 1/4” for 6” (5 ½” Net) deck boards and 3/16” for 4” (3 ½” net)
    boards. Also allow 1/4” from any structures including foundations or rail post.
  • Pre-drill Pilot holes ¾” from edges and ends and countersink for all screws using a minimum
    #10 high-quality Stainless-Steel screw. Coated deck screws may be used but could cause
    staining. Minimum screw penetration into joist of 1 ½”.
  • The most effective method to install your deck is Face Screw. We don’t recommend using any
    hidden clip fasteners or system.
  • When installing MANGARIS® hardwood decking, as with many other wood products, we
    recommend the use of a protective respiratory mask, gloves and eye protection. Wood dust
    may cause irritation and allergic effect. If you should have safety concern; please ask your
    local department of building and safety prior to starting your project

Gold Balau




West Malaysia, Borneo, Indonesia and Philipines.

General Description

A hard, heavy, and very dense heartwood with interlocking grains. Moderately slight and even texture.
Color : Purple-Gold to dark Gold-brown
Weight : average 850 kg/m3 (53 lb/ft3)

Specific Gravity : .93.

Mechanical Properties 

  • Bending strength – High
  • Crushing strength – High
  • Resistance to shock loads – High
  • Stiffness – High
  • Steam bending classification – Moderate


The timber dries very slowly with considerable degrade in thicker sizes, but distortion is not serious. Checking and splitting may be severe and existing shakes are liable to extend. Boards should be partially air dried before kilning. Movement is medium in service.

Working Properties

The wood is moderately difficult to work with machines as the interlocking grain and toughness has a blunting effect on tools. Owing to the high density of the timber, the cutting angle should be reduced to 20 degrees when planning. It is unsuitable for nailing or screwing, gluing results are a variable and it is rarely necessary to stain the wood. It can be polished satisfactorily.

Durability : Very durable. Extremely resistant from insect attack, fungal attack, and preservation treatment.
