The waterstop steel plate, also fondly known as the steel plate waterstop strip, stands as a tried-and-true material for effective waterstop solutions. Allow us to present you with an in-depth overview of this essential waterproof steel plate:
1, Material Characteristics
Water stop steel plates are meticulously crafted from corrosion-resistant materials, often featuring galvanized or stainless steel. Some variants are derived from robust Q235 steel plates, renowned for their excellent rigidity and durability. These plates are ingeniously designed in versatile shapes such as V-shaped, U-shaped, or flat plate configurations to seamlessly adapt to diverse construction demands. The edges are expertly folded to enhance bonding strength with concrete, ensuring long-lasting performance.
2, Working Principle
At the core of its function, the waterproof steel plate is strategically installed at the juncture between new and old concrete (construction joint). As water attempts to infiltrate through this joint, the steel plate skillfully intervenes to sever the water's path. Even if water manages to breach the gap between the steel plate and concrete, the plate's generous width serves to elongate the infiltration journey, thereby ensuring a reliable waterproof effect.
3, Specification and Model
Waterproof steel plates are available in a wide range of specifications, such as 200mm * 2mm, 200mm * 3mm, and 300mm * 2mm, among others. For convenience, they are typically processed into lengths of 3m or 6m for effortless transportation, though customization is an option to suit specific needs. The thickness is generally recommended to be above 3mm, with the width tailored to meet design specifications.
4, Installation Location and Method
The installation of the waterproof steel plate takes place at the concrete joint, where it is either welded or overlapped to forge a continuous, impermeable barrier. During installation, it is crucial to ensure a seamless connection with the bottom plate reinforcement, supported by appropriate protective measures to secure an enduring installation.
