National standard viaduct guardrail manufacturer directly supplies customized Longbang traffic facilities for roads
National standard viaduct guardrail manufacturer directly supplies customized Longbang traffic facilities for roads. The roof garden guardrail is an aluminum alloy light guardrail weighing 8 kg/m, with a profile wall thickness of 2 mm and fluorocarbon spraying. Fixed with chemical anchors without damaging the waterproof layer, the bottom windbreak net has a pore size of 5 mm to prevent objects from falling, which is suitable for roof greening. The garden landscape guardrail pursues harmonious coexistence with the natural environment and often adopts the form of a dry-stacked low wall of rough stones, with a height of 40 - 60 cm, having the functions of defining space and providing seating. The rough stones are selected from local river pebbles or mountain boulders, with a proper mix of sizes and a scattered arrangement. The gaps are filled with gravel or planted with drought-tolerant plants such as moss and sedum. An anti-corrosion wooden board with a width of 30 cm is laid on the top of the wall to form a natural seat. This kind of guardrail is low in cost, eco-friendly, and in line with the artistic conception of the landscape garden, and is widely used in parks and green spaces.

The size is 2×3 m, and it is fixed with 316L stainless steel claw parts with a tensile strength of 520 MPa, and the visible light transmittance is over 91%. The landscape guardrail around the sports stadium needs to have anti-climbing function, and adopts a spear-tip design at the top, with a spike height of 15 cm and a spacing of 10 cm. The height of the guardrail is 2.5 m, the columns are made of square steel tubes of 80×80 mm with a wall thickness of 3 mm and a spacing of 3 m. The mesh is made of diamond wire mesh with a pore size of 50×50 mm and a wire diameter of 4 mm. The surface is hot-dip galvanized and then sprayed with dark green paint to blend in with the surrounding greenery.

The wetland park guardrail imitates wood grain with an aluminum alloy, and the wood grain realism is 95%. The column spacing is 2 m and there are three layers of crossbeams. The screw piles are screwed into the soil for 1.2 m without excavation, and a transparent acrylic baffle is added on the top of the bird habitat area to prevent disturbance. The urban landscape river guardrail often adopts the combination form of granite and cast iron. The base is made of sesame gray granite, and the columns and crossbeams are cast iron parts. The size of the granite base is 60×40×20 cm, and the surface is axed for anti-slip, with each piece weighing about 130 kg. The cast iron columns are lined with steel bars to enhance the bending resistance, and the surface is hot-dip galvanized and then electrostatically sprayed with black matte paint. The crossbeams adopt an arc design to coordinate with the curved trend of the river. At the hydrophilic platform, the guardrail is locally lowered to 1 m and a bench is set up for citizens to rest and watch the water. This kind of guardrail is relatively high in cost (about 3000 yuan per meter), but has excellent durability and beauty, and is commonly seen in key waterfront landscape belts.
