Custom - made and processed thickened columns for national standard highway and bridge guardrails by Longbang Traffic Facilities. The interactive lighting guardrail has an LED pixel pitch of 10 cm and a single - particle brightness of 200 lumens. The sensor captures the position of pedestrians and the lights follow and flow. The response delay of the DMX512 protocol is less than 50 milliseconds, and it has extremely high ornamental value at night, becoming a highlight of night tours. The height and form of landscape guardrails in historical blocks need to be strictly controlled, generally not exceeding 0.8 meters, and cast - iron antique styles are adopted. The cast - iron parts are made by the lost - foam casting process, with fine patterns and an aged surface treatment to show the traces of time. The color of the guardrail is matte black, consistent with the color tone of the doors and windows of historical buildings. The column foundation is built with blue bricks, coordinated with the block paving. At the entrance of cultural relic protection units, the guardrails are set to be movable and can be temporarily removed during major events. This kind of guardrail is low - key and humble, not overshadowing the main scenery, and blends into the historical environment.
Custom - made and processed thickened columns for national standard highway and bridge guardrails by Longbang Traffic Facilities. The balcony guardrail is made of an aluminum - alloy frame with laminated tempered glass, with a wall thickness of 1.5 mm and a height of 1.1 meters. The glass has a thickness of 6 + 0.76+6 mm, which is safe for lamination. The column spacing is 1.2 meters, and the surface is powder - coated in white or grey, which is commonly used in modern homes. The campus landscape guardrail focuses on creating a cultural atmosphere. The balustrade is made of enamel steel plates, and school mottos, school emblems or famous quotes are baked on the surface. The enamel steel plate has a thickness of 2 mm, is resistant to acid - base corrosion, and has a service life of more than 30 years. The text is printed by the screen - printing process with a clarity of 300 DPI. The height of the guardrail is 1.1 meters, and the columns are H - shaped steel, with the surface painted in the school's theme color. In front of libraries and teaching buildings, the guardrail is partially raised to 1.5 meters to form a cultural wall for displaying students' art works. This kind of guardrail integrates safety education with cultural edification.

The lawn guardrail is made of white PVC material, 40 cm high, with two cross - beams and a vertical rod spacing of 10 cm. It is anti - ultraviolet, non - fading and maintenance - free. It can be installed by insertion without hardening the ground, and costs about 80 yuan per meter, widely used in villa gardens. The cultural relief bridge guardrail integrates regional cultural elements into the guardrail design and shows historical stories or folk customs through the relief process. The depth of the relief is 2 - 5 cm, pre - cast with GRC (Glass Fiber Reinforced Cement), and the flexural strength is not less than 12 MPa. The pattern design should avoid being too complex to affect the structural stress, and the relief area does not exceed 40% of the surface area of the guardrail. In historical and cultural cities, the reliefs on the guardrail often draw materials from local allusions, such as the dragon - pattern guardrail of the Zhaozhou Bridge and the stone - lion guardrail of the Lugou Bridge. There is a number on the back of each relief board, which is convenient for replacement and maintenance according to the drawing in the future.
