What is fplywood?
fPlywood, a wood structural panel, is sometimes called the original engineered wood product. [5] Plywood is manufactured from sheets of cross-laminated veneer and bonded under heat and pressure with durable, moisture-resistant adhesives. By alternating the grain direction of the veneers from layer to layer, or cross-orienting , panel strength and stiffness in both directions are maximized. Other structural wood panels include oriented strand board and structural composite panels. [6] Oriented strand board (OSB) is a wood structural panel manufactured from rectangular-shaped strands of wood that are oriented lengthwise and then arranged in layers, laid up into mats, and bonded together with moisture-resistant, heat-cured adhesives. The individual layers are cross-oriented to provide strength and stiffness to the panel. Produced in huge, continuous mats, OSB is a solid panel product of consistent quality with no laps, gaps or voids. [7] Glued laminated timber (glulam) is composed of several layers of dimensional timber glued together with moisture-resistant adhesives, creating a large, strong, structural member that can be used as vertical columns or horizontal beams, as well as curved, arched shapes. Glulam is the only engineered wood product that can be produced in curved shapes, offering extensive design flexibility. Laminated veneer lumber (LVL) is produced by bonding thin wood veneers together in a large billet. The grain of all veneers in the LVL billet is parallel to the long direction. The resulting product features enhanced mechanical properties and dimensional stability that offer a broader range in product width, depth and length than conventional lumber. LVL is a member of the structural composite lumber (SCL) family of engineered wood products that are commonly used in the same structural applications as conventional sawn lumber and timber, including rafters, headers, beams, joists, rim boards, studs and columns. [8] Cross-Laminated Timber (CLT) is a versatile multi-layered panel made of lumber. Each layer of boards is placed cross-wise to adjacent layers for increased rigidity and strength. CLT can be used for long spans and all assemblies, e.g. floors, walls or roofs. [9] Parallel strand lumber (PSL) consists of long veneer strands laid in parallel formation and bonded together with an adhesive to form the finished structural section. A strong, consistent material, it has a high load carrying ability and is resistant to seasoning stresses so it is well suited for use as beams and columns for post and beam construction, and for beams, headers, and lintels for light framing construction. [10] PSL is a member of the structural composite lumber (SCL) family of engineered wood products. [11] Laminated strand lumber (LSL) and oriented strand lumber (OSL) are manufactured from flaked wood strands that have a high length-to-thickness ratio. Combined with an adhesive, the strands are oriented and formed into a large mat or billet and pressed. LSL and OSL offer good fastener-holding strength and mechanical connector performance and are commonly used in a variety of applications, such as beams, headers, studs, rim boards, and millwork components. These products are members of the structural composite lumber (SCL) family of engineered wood products. [12].
What is wood used for?
Wood is a hard, fibrous tissue found in many plants. It has been used for centuries for both fuel and as a construction material for several types of living areas such as houses. Construction with wood is known as carpentry. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. In the strict sense wood is produced as secondary xylem in the stems of trees (and other woody plants). In a living tree it transfers water and nutrients to the leaves and other growing tissues, and has a support function, enabling woody plants to reach large sizes or to stand up for themselves. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

Overview
Petersianthus quadrialatus (also called toog and Philippine rosewood) is an emergent tropical rainforest tree species in the Lecythidaceae family. In the Visayas region called kapullan, in the Samar and Leyte areas - magtalisai. It is an indigenous tree species in the southeastern Philippines and one of the largest tree species in the Philippines islands.
Taxonomy
This species was firstly described as Terminalia quadrialata of the family Combretaceae in Merrill (1909:301), but was later renamed with a new genus for the family Lecythidaceae, i.e. Petersianthus by the original author.
Description
The leaves are simple, spirally arranged, obovate, 10–16 cm long and 5–8 cm wide. The base is acutely acuminate, long cuneate, apex rounded caudate. Glossy and dark green, the petioles are short with short soft hairs. Fruits are in capsule form in flat circular outline containing four large winged seeds.
Natural regeneration is very scarce. Seedlings can be found as far as 200 m from mother trees, es…
Distribution
Petersianthus quadrialatus endemic to the part of the southeastern Philippines - Mindanao, Leyte, Samar, Negros, Masbate and surrounding smaller islands.
Habitat
Petersianthus quadrialatus grows in an elevation that ranges from sea level up to about 400 meters. Tree is fairly common and grows scattered in primary and secondary tropical rainforest, near riverbanks or on hillside, in swampy and cool places. It thrives in an area where rainfall is evenly distributed throughout the year. It requires well-drained, clayish, sandy and loamy soils.
Uses
Leaves are medicinal especially in treating skin rashes. Seeds are edible and taste like groundnut.
