Rail fence is an important transport infrastructure, safety and practicality in the more stringent requirements. Structure: The column is divided into galvanized steel, peach-type column, as well as C-shaped steel columns and other dovetail, mesh steel screen is divided into packets, PVC plastic coated welded wire mesh, chain link fence and metal mesh and perforated metal mesh. Its general structure of columns and frame connected by a connecting piece can also be directly connected with the post card with mesh, bolted and riveted connections, the angle can be adjusted. Select high-quality low-carbon steel wire, welding from; grid structure concise, easy to transport, install undulating terrain without restrictions, especially for the mountain, slope, bending zone highly adaptive. Uses: mainly used for protection with highways, railways, bridges on both sides; security airports, ports and terminals; municipal building in the park, lawn, zoo, pool lake, roads, and residential segregation and protection. Features: 1. Column using pieces of concrete pouring, construction cost is low. 2. High strength, good overall stability. 3. Color plastic layer has a good anti-corrosion and decorative effect. The overall net enclosures beautiful harmony. 5. Closed railway, highway guardrail, zone enclosures, field fence. 6. corrosion, aging, sunscreen and other characteristics.
