What Is a Hexagonal Briquette?
A hexagonal briquette is a charcoal briquette shaped with six flat sides, often featuring a cylindrical hole in the center. This design is produced through an extrusion process and is widely used in barbecue, industrial heating, and culinary grilling applications due to its long burn time, high structural integrity, and efficient airflow.
Hexagonal briquettes are favored in many international markets for their performance consistency and stackable shape, making them ideal for both retail and commercial use.
How Hexagonal Briquettes Are Made
Raw Material Selection
Typically made from high-quality charcoal powder, such as coconut shell charcoal or hardwood charcoal, chosen for its high fixed carbon and low ash content.
Binder Mixing
Natural binders like tapioca starch are added to bind the charcoal particles, forming a durable, moldable mixture.
Extrusion Shaping
The charcoal mixture is extruded through a hexagonal-shaped die. Many products include a center hole to enhance oxygen flow and combustion efficiency.
Cutting and Drying
The extruded briquettes are cut to standard lengths (often 10 to 30 cm), then dried to reduce moisture content and solidify the structure.

Key Features of Hexagonal Briquettes
Consistent Shape and Size
Their uniform geometry allows for efficient packing, easy handling, and a professional appearance in both retail and foodservice contexts.
Center Hole for Airflow
The internal cavity increases air circulation, resulting in more efficient combustion and a stable heat output.
High Density and Compression Strength
Designed to resist breakage during shipping and use, even under high heat.
Long and Steady Burn
Ideal for extended cooking sessions or industrial applications that require consistent, sustained heat.
Common Applications of Hexagonal Briquettes
Barbecue and Grilling
Especially popular in Southeast Asia, the Middle East, and East Asia for both home and commercial grilling due to their long burn and minimal smoke.
Restaurant and Catering Use
Used in professional kitchens and open-flame cooking setups where stable, high heat is needed over several hours.
Industrial Heating
Employed in kilns or boilers as an alternative to traditional coal or firewood, particularly in small-scale industries seeking cleaner combustion.
Advantages of the Hexagonal Shape
Improved Combustion
The flat sides and hollow center allow more oxygen to reach the burning surface, resulting in better fuel efficiency.
Stackability and Packaging Efficiency
Hexagonal briquettes stack well in cartons and on pallets, reducing space requirements and improving logistics.
Reduced Ash and Smoke
When made from clean feedstock like coconut shell charcoal, hexagonal briquettes produce very low emissions, making them ideal for indoor or semi-enclosed cooking environments.

Did You Know?
A well-made hexagonal coconut shell briquette can burn for up to 3 hours in a controlled grill environment—making it a top choice for Korean BBQ, yakitori, and satay restaurants where consistent, high heat is essential.
