Hebi Railway Cement Protective Fence Manufacturer - Welcome to Enquire - Price for High-Speed Rail Concrete E-Type Cable Channel
Railway Protection Fencing - High-Speed Rail Protection Barrier - Manufacturer of Railway Enclosure Fencing, Main Components of Railway Protection Fencing and High-Speed Rail Protection Barrier:
Reinforced Concrete Pillar Metal Mesh Fence, consisting of reinforced concrete pillars, metal mesh panels, and connecting parts, with a protective height of 1.8 meters.
Piling:
Pillars are made of precast C30 reinforced concrete, with a cross-sectional size of 120mm x 120mm and a height of 2.5 meters. Four ø12mm circular holes are pre-drilled during the precasting, which are then secured to the side connection plates with bolts during installation.
Metal Mesh Sheets
Metal mesh sheets are made with Q235 rectangular tube frames, 30mm*50mm in size, and a tube thickness of 2.0mm; the internal wire mesh is made of HPB300 Φ4.0mm cold drawn steel wire, 75mm*150mm in specification.
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.
Precision requirements for the connecting plate: Length deviation ≤ 1.0mm, width deviation ≤ 0.5mm, thickness deviation ≤ 0.5mm, hole position deviation ≤ 1.0mm.
Railroad Protective Fence - High-Speed Rail Protection Barrier - Corrosion Treatment for Railway Enclosure Fencing
Metal mesh sheets for fencing gates should be fully galvanized after forming and then undergo hot-dip galvanizing (or spray painting) treatment. The galvanizing amount should be 270g/m², with the thickness of the plastic coating ranging from 0.8mm to 1.2mm. The color should be selected as dark green. The coating should be even, with consistent color, smooth surface, and free from defects such as drips, lumps, powdery bubbles, and exposed iron.
Fence Gate:
Gates are set according to the needs of work and electrical equipment inspection and maintenance operations.
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 columns via pins and pin sleeves.
Connective Components:
All bolts are designed with anti-theft features, consisting of a screw shaft, nut, and anti-theft washer. Installation and removal require special tools. Select anti-theft bolts of different sizes from the catalog based on the thickness of the connection points. After the nut is tightened and secured, the bolt head is fixed in place using a welding machine on-site to prevent the nut from loosening.
