Bufftech Fence

types of PVC fencing is becoming more developed. They have developed in the early 1990s for simple jobs and complex slats locking systems with tongue and groove panels "privacy" and a variety of molded ferrules and caps.

Major new design closure Tech in January 2000 show in Tampa, Florida, is a panel 1.5 x 13.4 in. Privacy tongue-in-groove with eight ribs domestic support, which said outdoor Profile Advantage is the largest fence on the market.

Cap layers are blooming with new colors during the last six months. Considering that the fences were usually either white, beige or gray Kroy recently added khaki, navy blue, forest green, maroon, and "TimberLast woodgrain (made by the interweaving of black ink in a tan or monolayer Profile of gray). Bufftech introduced a marbled effect woodgrain two years ago.

Most processors are closing profiles evaluation of foam as a means to increase production and possibly other attributes such as acoustic gain. The foam is used in PVC building profiles, but they tend to be the light of special items, not those free-standing, because the foam reduces impact resistance of PVC, but it increases the rigidity.

Reedy International Corp., Keyport, New Jersey recently introduced chemicals Safoam RIC-FP blowing agent for PVC. It is said to have the smallest particle size on the market-cons 7 microns to 35 microns previous products. Reedy sources note that the foaming rate increases by 10-20% due to CO2 in the blowing agent in the extruder acts as a lubricant or processing aid.

The next wave of developments is likely to include closure of wood composites. Wood-filled PVC and polyolefin rails, with or without layers of the CAP is already in use, but they are heavier and more expensive than conventional PVC fencing. Cap layers give a look painted, but composites can also be embossed or finished to look like natural wood grain.

Add flour, wood is a natural progression for the current makers PVC fencing, because of the greater heat resistance of wood composites. "Hypothetically a composite of wood must do better in warmer climates," says Al England, vice president of Strandex Corp., Madison, Wis., patented technology allows the profile of wood composite which is now widely used for bridges and rails.

Meanwhile, makers of wood-composite "plastic lumber" for other applications are being developed at the close of the market which include as temporary fence, wire mesh, fence manufacturers, steel fence post, fence, portable fence etc. One is Comptrusion Corp. in Toronto, a manufacturer of three years of decking timber filled PVC railings and window profiles. Vp Says Jim Pratt, "Our initial market analysis was that this would be a stretch for composites to compete with fences pressure treated wood. But we can not compete with plain PVC. I am pleased that the growth curve of PVC fencing is going off the charts, because it prevented people compare the cost of fencing plastic alternative to wood. "Comptrusion plans to increase production next year in Canada and the U.S." We will go after the market close when we get a handle on the volume for tracks and bridges, probably next year, "Pratt said . 'We will study the performance of fences such popular audio guide that the first, which is something of PVC alone can not do. "

Trex Co., Winchester, Va., which makes non-structural wood-plastic apron and strips of scrap wood fibers and reclaimed grocery bags and PE stretch film, is also the production of fence slats. "Fencing is an application more and more for us and a great use of nonstructural components such as vertical poles and slats," says sales and marketing manager Andy Ferrari.

Louisiana Pacific Corp. in Portland, Oregon, established its first factory-deck composite ABT Co. in Selma, Ala., last month. "The next logical extension was the fencing," said product development.
