When restoring the cultural relic bridge guardrails, we follow the principle of "restoring to the original state". The corroded cast - iron parts are remolded, and the casting composition is consistent with the original. The surface is treated to look old. For the missing decorative parts, after 3D scanning, wax molds are carved by CNC and then precision - cast. Dovetail tenons and copper rivets are used for connection, and the surface is coated with microcrystalline wax for protection. The landscape guardrails around sports stadiums need to have anti - climbing functions. A spear - tip design is adopted for the top, with a spike height of 15 cm and a spacing of 10 cm. The height of the guardrail is 2.5 meters. The columns are made of square steel tubes with a size of 80×80 mm, a wall thickness of 3 mm, and a spacing of 3 meters. The mesh is made of diamond - shaped wire mesh with an aperture of 50×50 mm and a wire diameter of 4 mm. After hot - dip galvanizing on the surface, dark green paint is sprayed to blend in with the surrounding greenery. An electric sliding door is installed at the entrance and exit, which can be accessed by card swiping or face recognition. This kind of guardrail combines safety and aesthetics and effectively prevents illegal intrusion.

The primary function of river channel guardrails is to prevent people from falling into the water while meeting the requirements of flood discharge. The net height on the riverside should not be less than 1.2 meters, and the distance from the bottom to the ground should not exceed 15 cm. The spacing between the vertical bars is 11 cm, and the spacing between the horizontal bars is 20 cm. When the flow velocity exceeds 2 m/s, the foundation should be deepened to 1 meter below the riverbed. The river channel guardrails beside the ancient city wall ruins need to be coordinated with the style of the city wall. Terra - cotta railings in the color of city bricks are used, and the surface is treated to look old to imitate the texture of the ancient city wall. The terra - cotta railings are fired at a temperature of 1200 °C, with a compressive strength of 50 MPa and a water absorption rate of ≤8%. The shape of the railings imitates the stone railings of the Ming Dynasty. The balustrade panels are carved with scroll grass patterns, and the capitals of the balusters are in the shape of lotus seats. During installation, the traditional mortise - and - tenon structure is adopted, and tung oil mortar is used for caulking. The foundation of the guardrail is hidden underground to avoid damaging the ruins. Each terra - cotta railing has an antique mark, integrating seamlessly with the ancient city wall.
The landscape overpass guardrails with optional materials are of guaranteed quality. We are the source factory, offering both protection and aesthetics. Longbang Traffic Facilities. The child - friendly guardrails have a double - layer protection design, with a main guardrail of 1.1 meters and a secondary guardrail of 0.6 meters added on the inner side. The steel pipes are covered with colored plastics. The spacing between the vertical bars of the main guardrail is 9 cm, and that of the secondary guardrail is 6 cm. A soft rubber skirting board is installed at the bottom to prevent collisions. The Japanese dry - landscape guardrails are in the form of bamboo fences. Well - selected Japanese timber bamboo over three - year - old, with a diameter of 3 - 5 cm, is smoked to prevent insects and then woven. The height of the bamboo fence is 1 meter, and the diamond - shaped weaving method is adopted, with a spacing of 2 cm between the bamboo strips. The columns are made of Chinese fir logs, which are peeled and then coated with tung oil for anti - corrosion. A pebble apron with a width of 30 cm is built at the bottom of the bamboo fence to prevent mud from splashing. This kind of guardrail is simple and natural, contrasting interestingly with the gravel and rocks in the dry - landscape, creating a Zen - like space. However, the lifespan of bamboo is relatively short, and it needs to be replaced about once every 5 years.
