HIGH TEMPERATURE RESISTANT: The roller surfaces are resistant to high temperatures up to 260°C. Finely machined with a matte finish, wear-resistant, smooth, and resilient. Suitable for high-temperature welding of PVC waterproofing membranes and fabric sheets. BRASS WHEEL: Made of sturdy brass material, pressure-resistant and corrosion-resistant. Ideal for welding tarpaulins, advertising fabrics, PVC waterproofing rolls, and other thermoplastic coil materials. Used for flattening during geomembrane and tunnel waterproofing welding, as well as corner pressing to prevent seam cracking and edge warping. FLEXIBLE OPERATION: Combo seam rollers feature double bearings for stable performance without deflection, enabling smoother and more flexible operation. Helps improve welding speed and construction quality. Detachable design allows for easy replacement. HANDLE DESIGN: The handle is made of selected wood, durable and ergonomically designed for comfort and reduced wear. Provides a comfortable grip and enhances usability during construction tasks. WIDELY USED: Seam roller is primarily used for membrane and sheet welding, as well as inspecting waterproof layer weld seams for defects such as incomplete or leaking welds. Commonly used for PVC/TPO coil seams, EPDM bonding seams, and similar applications.
