Railway Protection Fencing - High-Speed Railway Protection Railings - Manufacturer of Railway Closed Protection Fencing, Main Components of Railway Protection Fencing & High-Speed Railway Protection Railings:

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

Piling

The columns are made of precast C30 reinforced concrete with a cross-sectional size of 120mm x 120mm and a height of 2.5m. Four 12mm diameter round holes are pre-drilled when precasting. The columns are installed by securing the side connection plates with bolts.

Metal Mesh Sheets

Metal mesh panels are constructed with Q235 rectangular tube frames, dimensions of 30mm x 50mm, and tube thickness of 2.0mm; the internal wire mesh is made of HPB300 φ4.0mm cold drawn high tensile steel wire, with specifications of 75mm x 150mm.

Connector plate and bolt:

Column connecting plates and mesh connecting plates are made of 90° bent Q235 steel plates with a thickness of 4.0mm, 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 coating of 270g/m2.

Connector plate precision requirements: Length tolerance ≤ 1.0mm, width tolerance ≤ 0.5mm, thickness tolerance ≤ 0.5mm, hole position deviation ≤ 1.0mm.

Railway Protection Fence - High-Speed Rail Protection Barrier - Anti-corrosion Treatment for Railway Enclosure Fence

Metal mesh panels for grating doors should be galvanized as a whole and then undergo hot-dip galvanizing (or spraying) treatment. The galvanizing amount is 270g/m2, the immersion coating thickness is 0.8mm to 1.2mm, and the color is chosen as black green. The coating should be even, with consistent color, smooth surface, free of drips, lumps, powder bubbles, and iron leakage defects.

Fence Gate:

Gates are set up according to the needs of equipment inspection and maintenance work for engineering and electrical services.

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

Connective Accessories:

All bolts feature anti-theft design, consisting of screw shaft, nut, and anti-theft washer. Installation and removal require special tools. Select anti-theft bolts of different sizes 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 nut loosening.
