Plywood
Plywood is a composite wood panel made by layering thin sheets of wood veneer. These layers are glued together with each adjacent layer's wood grain rotated perpendicular to enhance strength and stability. Plywood is widely used in construction, furniture, and various other applications due to its versatility and structural integrity.
Synthetic resin adhesive is a versatile bonding agent commonly used in carpentry and woodworking. It is formulated with synthetic resins to provide strong and durable bonds between various materials, such as wood and laminates.
Plywood for general purpose is a versatile engineered wood product made by layering thin sheets of wood veneer. It exhibits strength and stability due to its cross-grain construction, making it suitable for various applications in construction, furniture, and DIY projects.
Marine plywood is a specialized type of plywood designed for high-moisture environments, such as boat construction and outdoor projects. It is made with waterproof adhesives and high-quality wood veneers, ensuring durability and resistance to rot, fungal decay, and delamination.
Veneered decorative plywood is crafted by overlaying a thin layer of aesthetically pleasing wood veneer onto a base of standard plywood.
lockboard is a type of engineered wood composed of a core made of wooden blocks or strips sandwiched between two layers of veneer. It is known for its strength, stability, and resistance to warping, making it a popular choice for furniture and interior applications.
Wooden flush door shutters with a solid core type refer to doors that have a solid and dense inner core, providing stability and durability. These doors typically consist of a solid wood or engineered wood core.
Plywood for concrete shuttering works is specifically designed for temporary formwork in construction. It offers a smooth surface, dimensional stability, and strength, providing an ideal mold for pouring concrete and ensuring a high-quality finish in the final construction.
