Work at height

Aerial Work (Aerial Work Company, Aerial Work Construction)

Business Scope:
I. 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, reinforcement, and anti-corrosion painting of exposed metal components such as ladders, platforms, protective nets, and lightning rods.

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

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

IV. Cleaning, repair, decoration, coating, and high-temperature-resistant fireproof coating for the exterior walls of high-rise buildings, mansions, factories, and coal conveyor trestles.

V. 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-free driveways and colored stamped concrete floors; repair, cleaning, and waxing maintenance for various industrial floors.

VI. Underwater Salvage
Engage in the construction of river, sea, and port terminals; dry docks, shipways, ship locks, navigation lift systems, channel dredging, land reclamation, port storage yards, embankment revetments, underwater rock blasting, and reef clearance projects; as well as corresponding silos, underwater foundations, earthwork, navigation markers, trestles, coastal and offshore hydraulic engineering; installation of port handling equipment, navigation structure equipment, underwater excavation, heavy lifting, and inland river salvage and obstacle clearance.

VII. Desulfurization and Anti-Corrosion
Coal used in thermal power plants contains sulfur, which produces sulfur dioxide (SO₂) during combustion, severely impacting the atmospheric environment after emission. Due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling SO₂ emissions in power plants. Therefore, FGD systems have become essential ancillary projects in many power plants, including retrofitting older plants that initially lacked them. Wet desulfurization anti-corrosion for the inner linings of chimneys, absorption towers, and flue gas ducts in thermal power plants; anti-corrosion using acid-resistant borosilicate foam glass bricks, vitrified ceramic tiles, glass flake coatings, spray polyurea, OM coatings, and acid-resistant mortars; repair of cracks and leaks in chimneys and flue gas ducts.
