Galvanized and Plastic-sprayed Combined Bridge Guardrail Physical Factory, Impact Resistance, Longbang Traffic Facilities
Galvanized and Plastic-sprayed Combined Bridge Guardrail Physical Factory, Impact Resistance, Longbang Traffic Facilities. The garden landscape guardrail is a dry-stacked rubble low wall with a height of 40 - 60 cm, with local river pebbles of different sizes arranged in a staggered way. The gaps are filled with gravel or planted with moss, and the top is covered with a 30 - cm - wide anti - corrosion wooden board to form a seat, which is eco - friendly and low - cost. The barrier - free bridge guardrail needs to meet the special needs of wheelchair users. The handrail height is set in two layers: the upper layer is 85 cm for adults, and the lower layer is 65 cm for children and wheelchair users to grasp. The end of the handrail is bent downwards by 15 cm to prevent sleeves from getting caught, and the surface is wrapped with a non - slip sleeve with a friction coefficient ≥ 0.6. The height of the kick - board at the bottom of the guardrail is not less than 10 cm to prevent the front wheels of the wheelchair from getting stuck in the gap. At the start and end of the ramp, the guardrail extends 30 cm as a tactile paving for the blind, with strip - shaped raised tactile signs on the surface. These detailed designs reflect the concept of universal design, allowing everyone to equally enjoy the convenience of bridge passage.
Galvanized and Plastic-sprayed Combined Bridge Guardrail Physical Factory, Impact Resistance, Longbang Traffic Facilities. The net height of the pedestrian overpass guardrail is not less than 1.3 meters, and the spacing between vertical bars is less than 11 cm to prevent children from getting through. The stainless - steel composite pipe is mirror - polished, and the handrail has an arc - shaped cross - section with a width of 5 - 7 cm. Double handrails are set on the uphill and downhill sections, and the embedded LED light strip at the bottom has an illuminance of 30 lux without glare. The guardrail of the landscape arch bridge is often designed in an arc shape that echoes the lines of the arch ring. The forged iron guardrail forms decorative patterns such as vines and waves through manual bending, combining classical charm with modern craftsmanship. The structural stress of this type of guardrail needs to specially consider the influence of horizontal thrust on the arch springing. Therefore, a reinforced column is set every 6 meters, and its cross - sectional size is 50% larger than that of ordinary columns. The surface treatment adopts hot - dip galvanizing and electrostatic spraying processes. The primer is zinc - rich paint, and the topcoat is acrylic polyurethane. The color can be customized to bronze, antique bronze or white according to the theme of the bridge. At the top of the arch, the height of the guardrail is appropriately reduced to 1.2 meters to ensure the viewing field, but the safety against falling is compensated by increasing the density of the railings to 10 per meter.

The floating steel anti - collision box of the river anti - ship - collision guardrail is 3×1.5×1 meters and filled with closed - cell foam, with a steel plate thickness of 6 mm. The red - and - white warning paint is connected to the river - bottom anchor through a chain, and the deformation of the box absorbs energy to protect the pier. The urban landscape river guardrail often adopts a combination of granite and cast iron. The base is sesame - gray granite, and the columns and beams are cast - iron parts. The size of the granite base is 60×40×20 cm, with a chiseled surface for anti - slip, and each piece weighs about 130 kg. The cast - iron column is lined with steel bars to enhance its bending resistance, and the surface is hot - dip galvanized and then electrostatically sprayed with black matte paint. The beam adopts an arc design to coordinate with the curved trend of the river. At the hydrophilic platform, the guardrail is locally lowered to 1 meter and a bench is set for citizens to rest and watch the water. This type of guardrail is relatively expensive (about 3000 yuan per meter), but it has excellent durability and aesthetics and is commonly found in key waterfront landscape belts.
