Frequently Asked Questions (FAQ)
-
Can this copper waterstop be used for curved joints with a small radius?
Yes, the 0.5mm annealed copper can be bent to a radius as small as 5mm without cracking, making it ideal for tight curves. -
What is the recommended method for joining two lengths of copper waterstop?
Overlap joint of at least 100mm and sealed with soldering or copper-specific adhesive. Alternatively, mechanical clamping can be used for temporary connections. -
Is the copper waterstop resistant to chemical attack in sewage or marine environments?
Copper has excellent corrosion resistance to most chemicals, chlorides, and sulfates. However, for highly acidic environments, we recommend consulting our technical team. -
Can the coil be cut to shorter lengths on site?
Absolutely. The coil can be cut with standard tin snips or shears. No special equipment is required. -
What is the shelf life of the product?
When stored in a dry, indoor environment, the copper waterstop can be kept indefinitely without degradation. Avoid prolonged exposure to moisture to prevent surface oxidation (patina). -
Do you offer custom sizes or perforations?
Yes, we can produce waterstops with different widths, thicknesses, and lengths. Perforations or embossed patterns for better concrete bonding are also available upon request. -
How does the 0.5mm thickness compare to standard 1.0mm or 1.2mm copper waterstops?
Our 0.5mm version is significantly lighter and more flexible, reducing installation labor and material cost. It still provides adequate strength for most joint sealing applications, though for very high hydrostatic pressure, thicker options may be preferred. -
What is the packaging for export?
Each coil is wrapped in protective plastic film, then packed in a woven bag or carton. For large orders, coils can be palletized and shrink-wrapped. Packaging can be customized.
