The Ultimate Guide to the Unique characteristics of teak wood Properties

This is a simple and easy guide. After reading, you will understand all about the properties of teak wood. 

Let’s take a closer look at what gives this wood its unrivaled performance.

The Distinct Physical Characteristics of Indonesian Teak

What sets teak furniture apart?


When it comes to identifying top-quality teak wood. Its physical traits are a dead giveaway of its superior properties.

Indonesian teak stands apart with unique characteristics. Evident in its appearance, hardness, density, and weight.

Appearance: A Warm, Luxurious Look

One of the most distinguishing features of Indonesian teak is its gorgeous warm brown color, ranging from golden honey to rich nutty hues. The wood’s straight, dense grain pattern has an inherent elegant look.

Compared to other wood species, teak’s fine texture results in a luxurious, naturally polished feel. Ideal for fine furniture-making.

Hardness: Among the Most Durable Woods

When referring to hardness ratings on the Janka scale. Genuine Indonesian teak ranks exceptionally high at 1070 lbf (4,760 N). This measurement indicates just how incredibly hard and durable teak’s dense hardwood is. Its hardness is closer to maple (1450 lbf) than the markedly softer oak (1360 lbf), exemplifying teak’s robust qualities.

High Density: That Delivers Strength

Indonesian teak’s density of around 670 kg/m³ once dried gives it substantial weight and solidity. This high density also contributes to the wood’s:

  • Exceptional dimensional stability to resist warping and shrinkage
  • Superior overall strength for structural integrity
  • Ability to endure significant wear and tear over time


The physical makeup and tight grains of Indonesian teak make it one of the most robust and hard-wearing furniture woods available. When properly treated, its density delivers longevity that lasts decades, if not centuries.

Ideal Working Properties for Furniture Makers

The Properties of Teak wood


Beyond its distinguished looks and solidity. Indonesian teak also possesses excellent working properties. That makes it a dream wood for furniture artisans and manufacturers like Zenddu. From solid workability to superb finishing traits, this wood excels.

Smooth Workability for Crafting and Carving

While teak is an incredibly hard and dense wood, it still maintains good workability for:

  • Sawing, cutting and turning with moderate blunting effects on tooling
  • Shaping, planing and carving with its generally straight grain pattern
  • Polishing and finishing to a beautifully smooth surface

These workability factors are why Indonesian teak has been so revered by skilled woodmakers. Its properties allow for intricate teak carvings and the shaping of complex designs.

Excellent Finishing Abilities

In addition to being easy to work on, genuine Indonesian teak also exhibits superior finishing properties:

Ability to take stains and polishes very well for rich coloring. Tight grain minimizes raised wood fibers when finished, and teak wood oil finishes nicely to enhance the warm patina.

So not only can teak be finely crafted into beautiful pieces, but it can achieve a luxurious, professional-grade finish seamlessly.

Dimensionally Stable and Consistent

Another ideal working trait is Indonesian teak’s high-dimensional stability. Once properly dried, teak has very low shrinkage and expansion rates compared to other woods. This stability allows teak furniture to:

  • Withstand humidity changes without warping
  • Maintain structural integrity over years of use
  • Provide consistent, reliable workability for manufacturing

Teak’s stability and workability make it a clear preference for Zenddu’s production of both indoor and outdoor furniture lined up precisely.

Teaks Growth and Size

Towering Presence: Teak trees are true giants. Reaching heights of up to 50m (150 feet) or even exceeding that mark in ideal conditions.

Moderate Growth Rate: Teak has a moderate growth rate. Ensuring the sustainability of forests for future generations. This responsible growth pattern contributes to the environmental friendliness of teak.

Unmatched Durability and Weather Resistance

Teak durability and weather resistance


One of the biggest reasons Indonesian teak is so highly prized is its incredible durability and ability to withstand outdoor conditions over the long term. This wood exhibits superior weathering abilities that make it an ideal choice for outdoor furniture and decorative pieces.

Built-In Resistance to Rot, Decay and Insects

Teak’s high natural durability comes from its unique properties:

  • Oily resins and extractives: Act as preservatives and repellents
  • High silica content: Makes teak less appealing to termites and pests
  • Dense structure: Tight grains prevent moisture penetration


Thanks to these natural qualities, Indonesian teak has an exceptional durability rating and is classified as a highly resistant wood.

So for any outdoor teak furniture or decorative pieces sourced from Zenddu, you can expect an incredibly long service life when properly cared for.

Our Indonesian teak has proven it can truly withstand the test of time outdoors.
