Handan Railway Cement Track Protection Fence Price - High-Speed Rail Concrete E-Type Cable Channel Manufacturer

Railway Protection Fence - High-Speed Railway Protection Barrier - Manufacturer of Railway Enclosure Fencing, Main Components of Railway Protection Fence and High-Speed Railway Protection Barrier:

Reinforced Concrete Pillar Metal Mesh Fencing consists of reinforced concrete pillars, metal mesh panels, and connecting parts, with a protective height of 1.8 meters.

Piling:

Poles are prefabricated from C30 reinforced concrete, with a cross-sectional size of 120mm x 120mm and a height of 2.5 meters. Four ø12mm round holes are pre-drilled during the prefabrication process, which are secured during installation by bolts to the connecting plates on both sides.

Metal Mesh Sheets

Metal mesh panels are constructed with Q235 rectangular tubes, with a size of 30mm x 50mm and a wall thickness of 2.0mm; the internal wires are made of HPB300 Φ4.0mm high tensile cold drawn steel wire, with a size of 75mm x 150mm.

Connector plate and bolt:

Pole connecting plates and mesh connecting plates are made of 90° bent Q235 steel plate, 4.0mm thick, available in two types, A and B, depending on the application location. Both the connecting plates and bolts are made of Q235 steel and are galvanized, with a galvanized amount of 270g/m².

Precision requirements for the connector plate: Length tolerance ≤ 1.0mm, width tolerance ≤ 0.5mm, thickness tolerance ≤ 0.5mm, hole position deviation ≤ 1.0mm.

Railway Protection Fence - High-Speed Railway Protection Barrier - Corrosion Treatment for Railway Enclosure Protection Fence

Metal mesh panels and grille doors should be galvanized and then undergo hot-dip galvanizing (or spray painting) treatment after forming. The galvanizing amount should be 270g/m², with the immersion coating thickness ranging from 0.8mm to 1.2mm. The color should be selected as black green. The coating should be even, uniform in color, smooth on the surface, free of drips, lumps, powder bubbles, and iron leakage defects.

Gates:

Gates are set up according to the needs of equipment inspection and maintenance work for civil engineering, electrical engineering, and other operations.

The reinforced concrete column metal mesh security fence can be available in either a single-door or double-door design. The single-door width is 1.5m, while the double-door width is 3m. The mesh design is consistent with the security fence, and it is connected to the columns via pins and pin sleeves.

Connective Components:

All bolts feature anti-theft design, composed of the screw, nut, and anti-theft washer. Installation and removal require special tools. Different anti-theft bolts with varying sizes are selected from the set according to the thickness of the connection points. After the nut is tightened and secured, the bolt head is spot-welded on-site to prevent the nut from loosening.
