MAIN TIMBER SPECIES

We use a wide range of timber species to meet any requirements in regard timber color, strength, durability and of course project budget.

All timber species are available from FSC-certified suppliers (excl. Merbau).

Timber	Type	Functional Uses	Notes
Merbau	Solid Timber	Visible Posts & Beams and Roof Structure, Flooring, Siding, Decking	FSC Certification is not available from any supplier.
Bangkirai	Solid Timber	VisiblePosts & Beams and Roof Structure, Flooring, Siding, Decking	Bangkirai has the same exceptional properties than Merbau, namely its natural durability in outdoor uses, without having the same weak points (tannins bleeding & unsustainable procurement).
Kempas	Solid Timber	Visible Posts & Beams and Roof Structure, Flooring, Siding, Decking	High Density Timber. Excellent alternative to Merbau & Bangkirai However, unlike these species, needs to be treated anti-termites (for outdoor uses).
Keruing	Solid Timber	Visible Posts & Beams and Roof Structure, Flooring, Siding, Decking	High Density Timber. Excellent alternative to Merbau & Bangkirai. However, unlike these species, needs to be treated anti-termites (for outdoor uses).
Pasang/ Tropical Oak	Solid Timber	Visible Posts & Beams and Roof Structure, Flooring, Siding, Decking	High Density Timber. Excellent alternative to Merbau & Bangkirai However, unlike these species, needs to be treated anti-termites (for outdoor uses). To be put forward in case architects & designers look for Brownish / Oak-like Timber.
Keranji	Solid Timber	Visible Posts & Beams and Roof Structure, Flooring, Siding, Decking	Not recommended for the Sapwood (White Keranji) is often mixed with Heartwood (Red Keranji)
Red Meranti Finger Jointed Lumber	Engineered Wood	Wall Framing, Rafters	Certified Tropical Wood. Quality alternative to Douglas Fir.
Sumatran Pinewood Finger Jointed Lumber	Engineered Wood	Wall Framing, Rafters	Low-cost alternative to Douglas Fir.
Laminated Veneer Board (LVL)	Engineered Wood	Wall Framing, Floor Joists & Base Not visible Roof Structure & Rafter	Low-cost alternative to Kerto. Inner Cross-ply (x2) allow structural uses.
WBP Exterior Plywood	Engineered Wood	Sheating, Ceiling	E0 Formaldehyde emission level. Alternative to CTBX.

TIMBER

When talking about timber and its characteristics, first its use should be specified. Timber for structural components must meet other requirements than for non-structural or parts which are later invisible.

Structural timber must posess the following specifications to be considered by us:

rich color, regular grain
high density and stability in service
natural resistance to termites
high fire-resistance
stronger than Teak

These preconditions are fully met by Merbau, a tropical hardwood.

The timber material is supplied in Grade A with a clean smooth grain, and no heartwood or sapwood. After planning, finely sanded S4S Components are protected with an Alkyd Resin Based Lasure. As with Merbau and other premium Indonesian species (i.e Bangkirai), we process only high quality materials sourced from renowned suppliers.

Bangkirai and Meranti are the two other hardwood species we use for non-structural timber. Their characteristics are similar to those of Merbau.

Other materials include: Plywood (panels), Pinewood (roof battens, decking strucutures) and hardware.

HIGH-PRECISION WOOD-WORKING

We operate as one of the few carpentry workshops all over South-East Asia fully equipped with MAFELL® Germany-Made portable tools.

We are planning to open a new computerized production unit equipped with Hundegger® Machines, a high-performance Automated Joinery Machine combining Industrial Productivity and High Precision.

STRUCTURAL ENGINEERING

We have builit many prefab buildings in cyclonic areas (Caribbean Islands, Hawaii, Tahiti, New Caledonia…) where construction requires wind resistance up to 300 kph.

The building system is specifically designed to meet the most demanding Building Code Standards. With several projects calling for large diameter post and beam structures, our factory's system specializes in precise engineering and custom designed metal hardware for.
