FAQ
Q1: What’s the difference between ramming pile and concrete foundation?
Ramming piles are driven directly into the ground for fast, low-cost installation, while concrete foundations use precast blocks for better stability on complex terrain. Foundation comparison guide, See detailed blog
Q2: How long does Zn-Al-Mg steel last?
The coating offers long-lasting protection, especially in corrosive environments. See detailed blog
Q3: Can this system be used on sloped or uneven land?
Yes. The height-adjustable structure allows flexible adaptation to terrain.
