It has a beautiful natural honey golden hue, but more importantly it is famous for being highly resistant to rot, pests (bugs, termites and worms), and fungi in both land and marine environments. Teak is the premier choice for any requirement in the marine industry, from decks and interior work, to docks. Teak is naturally water-resistant and physically very strong and durable. It is not prone to significant expansion or contraction with humidity changes. The oils in teak are what make it weather-resistant and it requires basically no care when left outside. Its high silica content gives it non-skid properties as well as durability. This makes teak a great choice in damp environments, or in areas where slipping could be very dangerous. Application: Ship and boatbuilding, veneer, furniture, exterior construction, carving, turnings, and other small wood objects. Below are the popular sizes we are offering: Teak Round Logs Teak round logs are a premium choice for those in the market for lumber and timber products. The round logs are the result of a peeling process that removes the bark and exposes the wood's natural grain. Teak Square Logs Teak square logs are created through a process that involves cutting the round logs into square pieces, exposing the natural grain of the wood. This process results in a beautiful and smooth surface that is ready for further processing. Teak Cut to Size Timber Teak Cut to size timber has been precisely cut to the desired dimensions and specifications of a customer. The benefit of cut to size timber is that it eliminates the need for the customer to do any additional cutting or shaping, saving time and effort. Origin: Burma, Ecuador, India, Panama, Costa Rica, Nigeria, Ghana, Brazil, etc. Item Specification Tree Size: 100-130 ft (30-40 m) tall, 3-5 ft (1-1.5 m) trunk diameter Average Dried Weight: 40.9 lbs/ft3 (655 kg/m3) Specific Gravity (Basic, 12% MC): 0.55, 0.66 Janka Hardness: 1,070 lbf (4,740 N) Modulus of Rupture: 14,080 lbf/in2 (97.1 MPa) Elastic Modulus: 1,781,000 lbf/in2 (12.28 GPa) Crushing Strength: 7,940 lbf/in2 (54.8 MPa) Shrinkage: Radial: 2.6%, Tangential: 5.3%, Volumetric: 7.2%, T/R Ratio: 2

Raw cashew is organic and naturally obtained from the tropical evergreen tree that produces the cashew nut and cashew apple. It is a widely consumed snack. About to 90% of the Raw Cashew nut is produced in Africa, some of the top cashew-producing countries are Cote dâ??Ivoire, Nigeria, Ghana, Tanzania, Benin, Guinea-Bissau, Burkina Faso, Senegal, Togo, Mali. Our network allows us to procure Raw Cashews directly from the source in Nigeria and Ghana. Our team of experts frequently visits the farmers and cooperatives, providing the right guidance and training so that they get a higher value for their harvest. When procuring RCN we ascertain the quality of the crop based on its quality measures such as its Kernel Out-Turn Ratio (KOR), Moisture content, and Nut Count. A high KOR fetches higher value, whereas a lower nut count means the crop has bigger nuts which attract a better price. We provide our customers with RCN from some West African countries like Nigeria, Ghana and Tanzania as per their required specifications.
