Excerpt from Select Structural Material, Its Characteristics and Uses: Manufactured From Genuine Long Leaf Pine (Pinus Palustris)
It is a natural law, correspondent to the coniferous woods, that the strength varies with the specific dry weight and density.
It is the quality of great density and specific dry weight that makes the longleaf species the strongest of the structural woods. This is supplemented by a straight grain and a comparative freedom from serious defects. This species is also distinguished by a large resin content and small percentage of sap wood. It is these qualities that make it the most durable of woods when exposed to the elements or to conditions of high constant temperature and relatively high humidity.* Longleaf pine (pinus palustris) is eminently qualified for use in bridges and trestles where great strength and durability are essential. Timbers for such structures must show a large percentage of heartwood and the other properties required by the Standard Specifications for Southern Yellow Pine Bridge and Trestle Timbers adopted by the American Railway Engineering Association. It is also adapted for use in factories and warehouses where great strength is required and in textile mills where durability and resistance to dry rot are the essential factors. It is the strongest because it is the most dense and the most durable because the most resinous.

Paperback. Condition: New. Print on Demand. This book extols the virtues of longleaf pine as a construction material. The author, a veritable expert in forestry, contends that longleaf pine is nature's strongest structural wood, endowed with an incredible density and resin content that enhances its durability, even in harsh outdoor conditions. The book further asserts that longleaf pine is superior to other softwoods, including shortleaf pine and loblolly, due to its exceptional strength-to-weight ratio and resistance to rot and pests. With a special emphasis on its structural applications, the author delves into the history and uses of longleaf pine in bridges, trestles, factories, and warehouses, arguing that it has been the preferred choice for centuries due to its unmatched strength and resilience. This meticulously researched and comprehensive book is an invaluable resource for architects, engineers, builders, and anyone seeking a thorough understanding of the remarkable properties and applications of longleaf pine, making it an essential addition to any library on construction materials.
