A steel plate waterstop is a heavy-duty waterproofing component designed for permanent, high-integrity sealing in critical construction joints. Fabricated from high-tensile steel, it provides unmatched structural reinforcement while preventing water migration in concrete structures subjected to extreme loads, pressure, and environmental stress.
Key Features & Benefits
1. Unrivaled Strength & Durability
Material Options:
Stainless Steel (304/316L): Corrosion-resistant for marine/chemical environments
Carbon Steel (Q235B): Hot-dip galvanized for cost-effective protection
Weathering Steel (Corten): Self-protecting patina for outdoor applications
Load-Bearing Capacity: Withstands concrete hydrostatic pressure + structural shear forces
2. Precision Engineering
Laser-Cut Edges: For perfect joint alignment
Pre-Drilled Anchor Points: Enables secure rebar tie-off during installation
Custom Fabrication: Available in flat, T-shape, or L-shape profiles
3. Superior Watertight Performance
