High-altitude Cleaning (High-altitude Operations, Curtain Wall Cleaning)

Business Scope:
1. Undertake the construction, installation, reinforcement, demolition, and heightening of various chimneys and water towers (brick, concrete, steel structures); concrete shell slipform reinforcement; tilt correction; replacement of inner linings; cleaning and dust removal; painting aviation warning color rings; replacement and reinforcement of exposed metal components such as ladders, platforms, protective nets, lightning rods, and anti-corrosion painting maintenance.

2. Cleaning, repair, anti-corrosion, waterproofing, and moisture-proof leak sealing for the internal and external walls of chimneys, cooling towers, water towers, urea granulation towers, and silos.

3. Surface treatment and specialized anti-corrosion for metal structures such as transmission towers, microwave towers, substation frameworks, bridges, various gantry cranes, steel beam roof trusses, gas tanks, (oil, acid, alkali, solvent) storage tanks, and chemical equipment.

4. Exterior wall cleaning, washing, repair, decoration, coating, and high-temperature resistant fireproof coating for high-rise buildings, skyscrapers, factories, and coal conveyor trestles.

5. Flooring Engineering
Undertake various terrazzo floors, epoxy, wear-resistant, hardened, dust-free, colored, anti-static, and metal (emery) cement-based wear-resistant floors; non-slip vibration-damping driveways and colored stamped concrete floors; repair, cleaning, and waxing maintenance for various industrial floors.

6. Underwater Salvage
Engage in the construction of river, sea, and port terminals; dry docks, shipways, ship lifts, navigation locks,航道疏浚, land reclamation, port area storage yards, embankment revetments, underwater rock blasting, and reef clearing projects; as well as corresponding silos, underwater foundations and bases, earthwork, navigation markers, trestles, coastal and offshore hydraulic engineering; installation of port loading and unloading equipment; installation of navigation structure equipment; underwater excavation; heavy lifting; inland river salvage and obstacle removal projects.

7. Desulfurization and Anti-corrosion
Coal used in thermal power plants contains sulfur, which produces SO2 during combustion, affecting the air environment after emission. Due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling SO2 emissions in thermal power plants. Therefore, FGD systems have become essential supporting projects in many power plants. Those previously built without such systems are now being retrofitted with FGD installations. Wet desulfurization anti-corrosion for the inner linings of chimneys, absorption towers, and flues in thermal power plants; anti-corrosion using acid-resistant borosilicate foam glass brick linings, vitrified ceramic tiles, glass flake anti-corrosion, spray polyurea, OM coatings, and acid-resistant mastics; repair of cracks and leaks in chimneys and flues.
