Road and bridge maintenance, railway culverts, high-speed railway tunnels, reinforcement of large-diameter steel corrugated plate culvert pipes, selection ofQ235 Q345  Q355Made of steel plate material, hot-dip galvanized for corrosion resistance, connected with flanges for higher load-bearing capacity and easier installation. It will be applied to underground storage tanks, windproof snow shelters, tunnel exhaust towers, etc. Our company's entire pipeline can be designed with short sections according to the specific length of the culvert, ensuring that the culvert length remains unchanged. The large-diameter steel corrugated culvert pipes produced by our company have passed throughCCPC、ISO9001Wait for product quality certification to ensure that any non-conforming products do not leave the factory and meet the requirementsJT/T791-2010National standard. Before leaving the factory, it undergoes galvanizing anti-corrosion treatment, and the theoretical anti-corrosion period can reach up to80Years or more. At the same time, our company can provide free drawing design and on-site investigation We also provide excellent installation team construction, technical guidance, backfilling guidance and other services.

Characteristics of galvanized corrugated steel pipe culvert:

1) Good strength The compressive strength is 1.5-3 times that of cement pipes More than 3-5 times the size of plastic pipes

2) Good flexibility Under a deformation of% 5, it still has a relatively high compressive strength of 16.8-41.76

3) Tube length Each tube has a length of 6-12 meters It can also be customized according to needs

4) The service life of 600 g/m2 galvanized threaded steel pipe is twice that of cement pipe Through corrosion testing conducted by the Metal Anti corrosion Control Engineering Technology Research Center, experiments were conducted in different soils and without sewage, and the service life reached over 50 years

5) Steel corrugated culvert pipes are lightweight The weight is 10% of that of cement pipes, and the comprehensive cost of transportation, construction, and installation is 30% cheaper than that of cement pipes

6) Good anti-corrosion sealing performance Effective measures to prevent secondary pollution of groundwater and environmental issues such as ground subsidence caused by drainage leakage
