We would like to introduce the "special canvas" such as seismic isolation canvas handled by Nissho Co., Ltd. Our company does not design "seismic isolation canvas." Production is carried out based on the drawings created after the design. If design is necessary, it will be done through a sales representative. The "canvas with right-angle flanges" can be produced in round-to-round, square-to-round, square-to-square, as well as in various shapes for the top and bottom. For "bellows and other special canvases," we first request the drawings to provide a quotation. At that time, we will discuss the details. *For more information, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Non-uniform Diameter Flange Joint." This product is available in "Round-Round," "Square-Round," and "Square" types. For more details, please contact us. All products are made to order and can be manufactured to your desired size. 【Round-Round and Square-Round Types】 ■ About Sewing Processing - For Round-Round (non-uniform diameter) and Square-Round canvas, the upper and lower flanges are sewn onto the main body. Therefore, if there are concerns about moisture penetration from inside to outside, a sealing treatment after sewing is necessary. * We can also accommodate specifications without flanges. ■ About Welder Processing - For welder processing, to maintain strength, the flanges and the main body are connected by sewing, and the sewing area is treated with a welder on top. * No sewing is performed on the Endless part (joint) of the main body. * For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Uniform Shape Expansion Joint" that we manufacture. The products are available in "round" and "square" shapes. The material and manufacturing method of the canvas used may vary depending on the application, so please feel free to consult us. All products are made to order, and we will confirm whether we can accommodate your desired size. 【Round Type】 ■ Round Expansion Joint - Sewing (Machine Processing) Production Range - Single can be produced from 50φ and double from 70φ. ■ Round Expansion Joint - Welder (Pressure Welding Processing) Production Range - Single can be produced from 50φ and double from 70φ. * There are restrictions on the length of L dimensions, so please inquire separately. * The above dimensions can be produced regardless of the presence of reinforcement lines. * For more details, please refer to the PDF document or feel free to contact us.
