No welding required (weld-free)! A bolt-joint operation platform designed to reduce labor hours.

We design and manufacture various types of frames tailored to our customers' requests, utilizing TEKLA STRUCTURES!

We would like to introduce our "bolt-joined operation platform" that can reduce both manufacturing and installation labor hours. In various plants and factory facilities, there are numerous floors and walkways installed for the purpose of operating, maintaining, inspecting, and monitoring equipment and tanks, both indoors and outdoors. These operation platforms are typically constructed using welding for assembly work, but this often involves the removal of welding thermal distortion and finishing work for painting, which contributes to high costs. Our company offers a "bolt-joined operation platform" that not only reduces welding labor hours but also contributes to a reduction in assembly labor hours at the installation site. By utilizing the general-purpose 3D software "TEKLA STRUCTURES," we conduct structural planning and verify equipment operability, and after confirming the strength of each component, we develop factory production drawings with the customer's approval if necessary. We also provide part processing drawings, product assembly drawings, installation drawings, 3D data, and various lists created from the 3D model. *For more details, please refer to the PDF materials or feel free to contact us.

basic information

【Features】 ■ By using 3D CAD compatible with BIM (Building Information Modeling) and avoiding welding, thermal distortion does not occur, enabling stable quality product supply. ■ By adopting bolts (torsion-type high-strength bolts) for all factory assembly parts, the manufacturing period is shortened, allowing for low-cost supply. ■ The installation labor for welding and protective work during welding, as well as the grinding range during finishing painting, is reduced. *For more details, please refer to the PDF materials or feel free to contact us.

We provide a comprehensive service from design work to product supply for various supports (platforms - operation platforms, walkways, stairs, handrails, ladders, etc.) and piping support devices (pipe supports) for plants and factory equipment. In the design phase, we conduct structural analysis and strength calculations, as well as planning design and detailed work utilizing 3D CAD (including the creation of installation drawings). Additionally, we offer integrated manufacturing from primary processing to assembly, welding, and painting, all linked with 3D CAD. Regarding piping support devices (pipe supports), we supply high-quality products that are mass-produced continuously using the streamlined production technology of our German partner, LISEGA, which boasts the world's top market share. We maintain a stock of standard products at our domestic factory in Japan, enabling us to respond quickly to short delivery times. 【Products Handled】 - Spring hangers and supports - Constant hangers and supports - Hydraulic snubbers (hydraulic dampers) - Rigid hangers - Pipe shoes and pipe saddles - Secondary steel materials for piping supports (beams and brackets) - Operation platforms (platforms), walkways, stairs, handrails, ladders - Piping racks - Viscoelastic dampers - Spring-type vibration isolation devices (spring devices) - Tuned mass dampers
