Product Description

Product Description

Ground Screw as an advanced foundation support solution, are widely used in numerous fields. With their unique spiral shape design, they can be quickly and effectively anchored into the ground, providing a stable foundation for various above-ground structures. There is no need for large-scale earth excavation and concrete pouring, which greatly improves construction efficiency and reduces the impact on the environment. They are favored foundation components in modern engineering construction.

Product Features:

1) Efficient and Convenient Installation Method
2) Excellent Load-bearing Capacity
3) Outstanding Adaptability
4) Adjustability and Flexibility
5) Environmental Protection and Reusability

Product Material:
 

1. Q235 Carbon Structural Steel: It has certain strength and toughness and relatively low cost. It is widely used in the production of screw piles for general construction and civil engineering projects. After hot-dip galvanizing treatment, its corrosion resistance is significantly improved, and it can effectively prevent rusting in ordinary environments and extend the service life of the piles.

2. Q345 Low-Alloy High-Strength Structural Steel: Compared with Q235 steel, Q345 steel has higher strength and better comprehensive mechanical properties. It is suitable for engineering projects with higher requirements for load-bearing capacity, such as industrial plants, large billboards, and wind turbine foundations. It can also be subjected to hot-dip galvanizing or other anti-corrosion treatments to enhance its corrosion resistance in harsh environments.

FAQ

Q1.What is the difference between galvanized aluminum magnesium steel and ordinary galvanized steel?
A:Aluminum magnesium coating significantly improves corrosion resistance, especially suitable for high salt spray and acid rain areas, with a lifespan extension of more than 50%.

Q2.Does the bracket require additional anti-corrosion treatment?
A:No need! The coating and passivation treatment have been completed before leaving the factory, and it can be used directly.

Q3.Can you provide a load-bearing calculation report?
A:We can provide third-party inspection reports along with the goods and support customized wind/snow load analysis for the project.

Q4. Do you accept sample orders?
A:Support! 3 sets minimum order, shipped within 7 days, sample fee can be deducted from bulk order.

Q5.Payment method and warranty period?
A:Accept TT/LC, with a 15 year warranty (free replacement for non-human damage).
