What is Hardwood Timber?
Hardwood timber refers to wood sourced from slow-growing tropical or deciduous trees, typically with higher density, strength and natural durability compared to softwood. In Singapore, the term most commonly refers to tropical hardwoods from the Southeast Asian region — species such as Balau, Chengal, Kapur and Keruing — which are widely used in heavy-duty structural and outdoor applications.. In Singapore, tropical hardwood is commonly supplied as sawn timber — cut from the log into rectangular cross-sections ready for use in construction, marine and fabrication projects. Unlike softwood, tropical hardwood does not rely solely on chemical treatment for durability. Species like Chengal and Balau are naturally resistant to moisture, decay and insect attack, making them suitable for outdoor and marine environments even in Singapore's humid tropical climate.

Hardwood Decking Wood, Roof Timber & Sawn Wood Species
We supply a comprehensive range of tropical hardwood timber products tailored to rigorous structural parameters:
Balau Wood / Balau Timber
Balau timber is an ultra-dense hardwood specified extensively for heavy-duty structural engineering and marine construction. Featuring high bending and crushing strength, balau wood is ideal for heavy structural frameworks, boat building, and high-traffic decking wood installations.
Density: 800–1,100 kg/m³ (air dry)
Durability Class: Class 1–2 (naturally durable)
Properties: Hard, very heavy and dense. High bending and crushing strength. Interlocked grain can blunt cutting tools. Naturally durable; typically treated with CCA or preservative for outdoor use.
Applications: Premium structural timber beam & decking wood supply
Chengal Wood / Chengal Timber
Chengal wood is widely recognized as the most durable tropical hardwood timber available in the Singapore construction market. Classified under Durability Class 1, Chengal timber possesses exceptional natural resistance to moisture, insect attack, and fungal decay. It is the premier choice for long-service-life outdoor applications, heavy structural frameworks, bridges, walkways, and marine environments.
Density: 770–1,050 kg/m³ (air dry)
Durability Class: Class 1 (highest natural durability)
Properties: Very durable and long-lasting. High natural resistance to moisture, decay, fungi and insects. Strong and dimensionally stable. Resinous — requires care in finishing and gluing.
Applications: Outdoor decking and walkways, bridges and heavy structures, marine environments, jetties and pontoons
Kapur Wood / Kapur Timber
Kapur timber is a versatile and cost-effective tropical hardwood used extensively in Singapore for general construction and interior applications. Kapur wood offers a good balance of strength and workability, making it popular for formwork and structural framing where Chengal or Balau would be over-specified.
Density: 640–800 kg/m³ (air dry)
Durability Class: Class 2–3
Properties: Moderately strong and durable. Relatively easy to machine, plane and work with. Good nailing and screwing properties. Cost-effective for non-exposed applications.
Applications: General construction framing, formwork and shuttering, interior structures and joinery, mouldings and panelling
Keuring Wood / Keuring Timber
Keruing timber is a practical, cost-effective hardwood widely used in Singapore for construction, formwork and industrial applications. Keruing wood is particularly common in temporary structures, formwork and plywood core production. Preservative-treated Keruing is used for poles and piles.
Density: 720–900 kg/m³ (air dry)
Durability Class: Class 3–4 (chemical treatment recommended for outdoor use)
Properties: Moderately heavy and strong. Good structural performance for the cost. Resinous — variable gluing and finishing. Requires preservative treatment for outdoor or ground-contact use.
Applications: Formwork and temporary structures, plywood and panel production, internal framing and floors, preservative-treated poles and piles

Frequently Asked Questions (FAQ)
Q: What is hardwood timber used for in Singapore?
A: Hardwood timber is used for structural construction, outdoor decking, flooring, marine and waterfront structures, bridges, formwork and heavy-duty industrial frameworks. Species like Balau timber and Chengal timber are especially popular for outdoor and marine applications due to their high natural durability.
Q: What is the difference between Balau timber and Chengal timber?
A: Both are premium tropical hardwoods, but Chengal wood (Durability Class 1) is the most durable hardwood available in Singapore and is naturally resistant to decay and moisture even without treatment. Balau wood (Durability Class 1–2) is also very durable and is widely used for structural work and decking, typically with CCA or preservative treatment for outdoor applications. Chengal wood commands a higher price; Balau wood is the more widely available and cost-effective alternative.
Q: What sizes of hardwood timber do you supply?
A: We supply standard and custom dimensions. Common cross-sections range from 25×25mm to 200×200mm, with lengths from 1m to 6m. Our in-house cutting facility allows us to produce timber in specific dimensions for your project.
Q: What is sawn timber and where can I buy sawn timber in Singapore?
A: Sawn timber refers to timber that has been cut from logs into rectangular cross-sections at a sawmill, producing dimensional lumber ready for construction, structural and outdoor applications. In Singapore, Plony Industries supplies hardwood sawn timber in standard and custom sizes with planing and chemical treatment available on request.
Q: Which hardwood is best for outdoor decking in Singapore?
A: Chengal wood and Balau wood are the most commonly recommended species for outdoor decking wood in Singapore's humid tropical climate. Chengal timber is naturally resistant to moisture and decay (Durability Class 1) and can be used without treatment for outdoor applications. Balau timber is also highly durable and widely used for decking, typically with preservative treatment.
Q: How long does hardwood timber last outdoors in Singapore?
A: Lifespan depends on species and treatment. Untreated Chengal wood can last 15–25 years or more in outdoor conditions. Treated Balau wood typically lasts 10–20 years in exposed environments. Kapur wood and Keruing wood are better suited to covered or interior use unless chemically treated. Regular maintenance (cleaning and recoating) extends service life.
Q: Do you provide chemical treatment for hardwood timber?
A: Yes. Plony Industries is an authorised LONZA service provider for chemical pressure treatment. Timber is impregnated with preservative under vacuum and high pressure at our own facility. We also supply and apply SOLIGNUM brush-on preservative. Treatment is available for general preservation, fire retardancy and enhanced outdoor durability.
Q: Where can I buy heavy duty structural timber beams or roof timber in Singapore?
A: Plony Industries supplies custom-cut timber beam units, load-bearing rafters, and structural roof timber directly to commercial infrastructure sites island-wide. We ensure all items meet required engineering benchmarks for heavy duty structural timber.
Q: Is hardwood timber suitable for BCA-compliant or HDB structures?
A: Tropical hardwood is widely used in Singapore construction. If your project mandates a bca compliant structural timber grade or specific HDB framework compliance, contact our technical team. We will recommend the correct density, structural dimensions, and pressure treatment profiles to pass strict compliance criteria.
