In view of the high-loss working conditions of trunk highways, Luyi optimizes the production process pertinently by thickening the base plate of guardrails to enhance bending resistance and impact resistance. Meanwhile, the company strictly controls the whole hot-dip galvanizing process to resist corrosion and wear caused by rain, dust and long-term vehicle impact, ensuring long-term road traffic safety.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img alt=\"\" decoding=\"async\" width=\"1000\" height=\"600\" src=\"http:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8.webp\" class=\"wp-image-5497\" srcset=\"https:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8.webp 1000w, https:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8-300x180.webp 300w, https:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8-768x461.webp 768w, https:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8-18x12.webp 18w, https:\/\/luyitraffic.com\/wp-content\/uploads\/2026\/07\/8-600x360.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">National and provincial highway renovation has always been Luyi\u2019s core advantageous business.
