High Temperature Resistance: The pressure wheel surface is made of high temperature resistant silicone material, capable of withstanding temperatures up to 260°C. It features a matte frosted finish, offering wear resistance, smooth operation, and enhanced resilience. Suitable for high temperature welding of PVC waterproofing membranes and tarpaulin materials. With Test Probe: The seam roller includes a built-in probe to effectively inspect welding joints on TPO membranes, allowing thorough checking of all seams to detect missed or incomplete welds and ensure consistent weld quality. Convenient Operation: Designed with a single wheel and dual bearing system, the seam roller operates smoothly without deviation, enhancing flexibility and preventing jamming during use. This design improves welding efficiency and construction quality. High-speed steel bearings provide added stability, and the sturdy, detachable structure allows for easy replacement and maintenance. Handle Design: Features a handle crafted from premium wood, designed for durability and ergonomic comfort. The wear-resistant handle offers a secure, comfortable grip that fits naturally in the hand. Wide Application: Ideal for welding and inspecting membrane and sheet materials, including checking for incomplete or missed welds in waterproofing layers. Compatible with PVC, TPO, EPDM, and other common membrane materials.
