Definition of Lauan Plywood
To answer the question, “What is lauan plywood?” it’s important to break it down. Lauan plywood is made from the wood of trees that belong to the Shorea genus, which are primarily found in tropical regions of Southeast Asia, including the Philippines, Indonesia, and Malaysia. The trees from this genus are generally classified as hardwoods, and the plywood produced from their wood is typically light to medium reddish-brown in color with a smooth texture and fine grain.
The plywood itself is constructed by bonding thin layers, or veneers, of lauan wood together with adhesives. These layers are laid out in a cross-grain manner, meaning each layer’s grain is oriented perpendicular to the layer beneath it. This arrangement helps to increase the strength and stability of the plywood, reducing the risk of warping or splitting over time.
In addition to its structural benefits, lauan plywood also offers a relatively affordable alternative to other higher-end plywood types like mahogany, while still providing an attractive and durable finish. It’s versatile and often chosen for both its practical and aesthetic qualities.

Today, the production of lauan plywood is a global industry, with strict regulations in place to ensure the wood is sourced sustainably.
Production Process of Lauan Plywood
Raw Material Selection
So, what does lauan plywood refer to in terms of raw materials? The process of making lauan plywood begins with the careful selection of trees. Manufacturers look for mature Shorea trees that are free from defects, such as knots or splits. The quality of the raw material is key to producing high-quality plywood. The trees must be strong and stable, with a smooth grain that will allow them to be sliced into thin, uniform veneers.
Sustainability has become a growing concern in recent years, and many manufacturers now prioritize sourcing lauan timber from responsibly managed forests. The Forest Stewardship Council (FSC) certification, for example, ensures that the wood is harvested in a way that minimizes environmental impact and supports long-term forest health.
Lamination and Veneer Process
The process of turning lauan wood into plywood begins by slicing the logs into thin veneers, which are typically between 1 and 3 millimeters thick. These veneers are then layered on top of one another in a crisscross pattern, with each layer’s grain running perpendicular to the one beneath it. This cross-grain layering helps improve the plywood’s strength and stability.
Once the layers are aligned, they are glued together using a strong adhesive that bonds the wood fibers. Heat and pressure are often applied during this step to ensure the layers bond firmly and that the plywood has a uniform thickness throughout. This process ensures that the plywood will have good structural integrity and durability for a variety of applications.
Manufacturing Methods
Lauan plywood is manufactured using advanced machinery that helps ensure precision in every stage of production. The logs are first debarked, and then they are sliced into veneers using rotary or slicer methods, depending on the desired texture of the plywood. After the veneers are cut, they are sorted based on quality, with the best-quality sheets reserved for higher-grade plywood.
Adhesives are applied to the veneers, which are then stacked and pressed under heat to bond the layers. Depending on the manufacturer, some mills may use a hot press, which allows the glue to set quickly and ensures a strong bond. Some manufacturers also use cold presses or even vacuum presses to achieve a more uniform bond.
Quality Control
Quality control is a critical aspect of the production of lauan plywood. Each sheet of plywood must meet strict standards to ensure its durability and performance. The plywood is tested for various properties, including its resistance to moisture, flexibility, and overall strength. Any defects, such as warping or air bubbles between the layers, are identified and corrected before the plywood is shipped.
The final product is often subjected to visual inspection as well, checking for consistency in appearance and texture. Lauan plywood manufacturers take pride in ensuring that their product meets or exceeds industry standards, particularly in regard to aesthetics and functionality.
