New Applications for Preservative Treated Wood

In the past the treating industry looked only to the railroad and utilities for its markets, but today a new market for pressure-treated wood is opening up on the farm. The trend toward fewer, larger farm units has stimulated interest in economical, labor-saving construction. Pole frame structures, using pressure treated poles set at 12, 14, or 16-foot intervals, with horizontal members bolted or nailed on, are extremely rigid, very flexible in use, and simple to erect and maintain. With or without floors, these buildings are excellent for housing and feeding cattle, fairground pavillions, storage of farm machinery, etc. Horizontal silos, cattle feeders, and hay storage, can also be constructed with treated lumber. Fence posts, vineyard posts, and highway guard and guide rail posts can be fabricated from treated wood. Pressure treated pilings are gaining wider acceptance in marine applications. Composite deck bridges, used in wharves, combines pressure creosoted timber and concrete to form an economical and durable structure. The concrete is practically welded to the timber by a series of grooves, up-lift spikes, steel shear developers, and reinforcing steel. The treated timber is used under tension in the under part of the structure, while the concrete is under compression and forms the floor. Railway car decking, roller coasters, and board walks provide other markets. Creosoted wood blocks make the finest available factory flooring; it withstands impact and is easier on the workmen, while it outwears other materials. The demand for treated wood products is steadily increasing.
