Sankeshu waterborne industrial coating helps Shanghai Lupu Bridge structural overhaul and re-coating project

In June 2003, Lupu Bridge, known as the "first arch in the world", was officially completed and opened to traffic, becoming the fifth bridge crossing the Huangpu River in Shanghai. Like a giant silver bow, it flew across the river from north to south. With its rainbow momentum, soft curves and exquisite construction, it has become another landmark building in Shanghai.

As the days went past, lupu bridge opened to traffic operation has been almost 20 years, all the year round light, wind, rain and the bridge itself expands and makes the Bridges are aging, defect, damage, etc., mainly for level soto breakage, PE tensile crack, most of the area of the pulverization level paint, severe corrosion minority area, There are numerous problems in the safety and structure maintenance, which affect the safety of bridge structure, and it is urgent to carry out structural maintenance.

Sankeshu Industrial Paint targeted analysis on various kinds of old paint film of bridge steel arch beam, according to the concrete corrosion environment of the bridge and the corrosion of the old coating, according to the principles of long-term protection, construction convenience, safety and environmental protection, determine the detailed maintenance plan, put forward the technical solutions of anti-corrosion supporting system. Coat with a decent water conservation system that is non-toxic, non-harmful, and environmentally friendly. With great weather resistance, high corrosion resistance, outstanding wear resistance, enhanced wind stability, safety and applicability, and outstanding color and gloss durability, it not only cracks but also maintains the look of the image.

The construction area of the project is more than 350,000 square meters, and it is scheduled to be completed by the Spring Festival of 2023. Interior structures are complex and confined spaces, poor ventilation conditions, narrow spaces, construction difficulties, high safety and environmental protection requirements, coating quality assurance life requirements of more than 15 years, three-tree industrial coatings to overcome various construction conditions, and coordinated project implementation for smooth and on-time implementation.

Bridges are the "gravitation factor" and the "fulcrum" of the urban economy. With the bridge, the urban layout is becoming more rational and the city's economy is advancing by leaps and bounds, which has considerably contributed to social development. Lupu Bridge is a symbol of Shanghai's individuality and charm. Sankishu Industrial Coatings has kept up with the national development strategy and served the country's development, striving to revitalize the city and its architecture with high-quality products and excellent services, helping the city's cultural heritage and innovation, and realizing a better life.
