Discover our high-performance serrated paper pulp strips for precast beam construction – an eco-friendly, cost-effective upgrade to traditional sealing methods. Perfect for preventing mortar leakage and ensuring smooth demolding!

Why Choose Our Upgraded Serrated Paper Pulp Strips?

Traditional foam or rubber sealing strips often fail under high-pressure concrete pouring, leading to messy leaks, uneven edges, and costly rework. Our next-generation serrated paper pulp strips solve these problems with a unique "big-small tooth" design, offering superior sealing and durability for precast beam molds.

Key Benefits:

✔ Enhanced Sealing Performance – The interlocking serrated edges create a tighter seal against mold gaps, preventing mortar leakage.
✔ Eco-Friendly & Biodegradable – Made from high-strength paper pulp, reducing plastic waste compared to foam/rubber strips.
✔ Easy Demolding & Reusability – Unlike sticky tapes or rubber strips, our pulp strips release cleanly without residue.
✔ Cost-Effective – More affordable than rubber alternatives while lasting longer than foam.
✔ Customizable Sizes – Available in multiple widths (10mm–50mm) and thicknesses (5mm–20mm) to fit any mold.
