1. Product Overview
Our professional manhole steel formwork is specially designed for municipal sewer, rainwater drainage, and underground pipeline inspection well construction. Adopting high-strength carbon steel structure, it ensures precise forming, smooth concrete surface, no deformation during pouring, and effectively improves construction efficiency.
We support customized circular, square, rectangular and special-shaped inspection well molds, suitable for on-site cast-in-place and factory precast production, serving global road, municipal and infrastructure contractors.
2. Core Advantages
✅ High Precision & Stable Structure
Reinforced by thick back ribs, the mold does not expand or deform under concrete pressure, ensuring uniform well wall size and smooth finish.
✅ Multiple Shapes & Custom Sizes Available
Customizable diameter, height, and opening position for circular, square, rectangular, stepped and eccentric manholes to match different drainage standards.
✅ Long Service Life & High Reusability
Made of Q235 high-quality steel plate, reusable for more than 50 times, significantly reducing long-term project cost.
✅ Easy Assembly & Quick Demolding
Bolt-connected modular design, convenient for installation and disassembly on site, saving labor and construction time.
✅ Excellent Anti-Leakage Performance
Matched with professional locking system, tight splicing without slurry leakage, improving concrete compactness for underground infrastructure.
✅ Factory Direct OEM & ODM Supply
Accept custom thickness, surface treatment and design, support bulk order and on-time delivery for global projects.
