Pick a product, enter your dimensions within the range, the density and how many containers you need, and add it to your quote. We sell by full container only. Have your own wood? We kiln-dry, laminate or sand it.
Need a size outside these ranges? Message us on WhatsApp and we'll look into it.
Bring your wood and we return it dried, laminated or sanded to the size you need.
Artificial drying for 11 to 14 days under controlled high temperature: it eliminates insects, pests and fungi and leaves the wood at 8 – 12 % moisture.
Gluing and pressing boards into solid blocks, with the adhesive chosen for the end use.
Wide-belt sanding on both faces down to final thickness, with a uniform, ready-to-use surface.
Balsa ranges from 80 to 300 kg/m³ within the same tree. We weigh and grade every piece into four grades — lightweight, standard, heavy and extra heavy — so you receive exactly the density your project needs.
| Grade | Sheets | Balsa glued blocks | Sticks | What it is for |
|---|---|---|---|---|
| Lightweight | to be confirmed | 85 – 115 kg/m³5,3 – 7,2 lb/ft³ | 5 – 8 lb/ft³80 – 128 kg/m³ | The lightest. Where weight rules: model aircraft, free flight, scale models. |
| Standard | to be confirmed | 135 – 176 kg/m³8,4 – 11,0 lb/ft³ | 6 – 15 lb/ft³96 – 240 kg/m³ | General purpose. The most requested grade for hobby, distribution and crafts. |
| Heavy | to be confirmed | 200 – 242 kg/m³12,5 – 15,1 lb/ft³ | 10 – 18 lb/ft³160 – 288 kg/m³ | More strength and stiffness. Structural parts, fine carving, industry. |
| Extra heavy | to be confirmed | 240 – 288 kg/m³15,0 – 18,0 lb/ft³ | 14 – 20 lb/ft³224 – 320 kg/m³ | The densest and hardest. Maximum compression and impact resistance. |
ECUBALSHEET S.A.S. is born in Guayas, Ecuador, from the Sereni family, pioneers of the industry and present in the balsa market since 1975. Five decades producing, industrializing and exporting balsa to the whole world gave us the experience and the human capital that today we apply to what the sheet and stick market never had from the source: piece-by-piece density control and calibration with a wide-belt sander.
We sell directly from the factory and by full container to importers, distributors and the composites industry, with no intermediaries.
Ecuador Balsa Sheet is a supplier and exporter of balsa wood from Ecuador: balsa sheets, balsa sticks and balsa glued blocks, kiln-dried and graded by density, for composite cores (wind turbine blades, marine, automotive), model aircraft and scale models. Factory in Durán-Yaguachi, Guayas; FOB Guayaquil shipments by full container (FCL).
Balsa wood (Ochroma pyramidale) is a remarkable material with unique properties and characteristics. Its mechanical strength, elasticity, dimensional stability, fire resistance and sustainability make it highly sought after in various industries.
The balsa tree is one of the fastest-growing trees in the world: it can reach up to 30 metres in just six years. That rapid growth allows a sustainable and renewable production of this exceptional wood.
With a low weight and a density of 100 to 200 kg/m³, balsa enjoys an excellent reputation. Despite being lightweight, it is strong and flexible, making it an ideal thermal, acoustic and electrical insulator.
Every bundle ships with its measured density, within the grade you ordered: lightweight, standard, heavy or extra heavy.
Wood sanitised and dried to 8 – 12 % moisture: no insects, pests or fungi, and stable on arrival in dry or humid climates.
Order your sizes in inches or millimetres: we work with both and quote in the unit you use.
You buy from the producer, by full 20' or 40' container, FOB Guayaquil or CIF to your port.
We work with local growers of fast-growing balsa in Guayas and Los Ríos, selected for traceability and quality.
We select the green wood, sanitize it and dry it artificially for 11 to 14 days. Controlled exposure to high temperature eliminates insects, pests and fungi and leaves the wood at 8 – 12 % moisture.
The dry wood is cut on the multi-blade saw into boards slightly over the final thickness.
Wide-belt sander on both faces down to the exact thickness, with a uniform, ready-to-use surface.
Every sheet is weighed and graded by density. Anything outside the grade stays out of the bundle.
Shrink-wrapped bundles, export boxes or ISPM-15 fumigated pallets. Shipped from the port of Guayaquil.

The dry wood moves to the cutting section: thin-kerf multi-blade saw to get the most out of every board.
Boards are glued and pressed under controlled pressure into a solid block of the requested thickness and length.
Every block is weighed and graded by density. Anything outside the grade stays out of the bundle.

The dry wood is cut on the multi-blade saw to the requested thickness and width, from 1" to 4" per side.
Every stick is squared and cut to length, up to 48". Straight cut, no warping or knots.
