Achieving quality stabilization in PC construction! Unified management made possible by a manufacturer of anchor bolts.

Our "Reinforced Column Base Frame for PC Construction Method" is a frame developed by mobilizing the know-how accumulated over many years in anchor set construction to ensure the accuracy of the main reinforcing bars for PC construction, which has been a source of concern until now. It eliminates the hassle of adjusting the main reinforcing bars after concrete placement and significantly reduces the stress during the installation of PC columns. 【Features】 ■ Stabilization of quality in PC construction ■ Unified management possible because we are an anchor bolt manufacturer ■ Consistent support from design to construction *For more details, please refer to the PDF document or feel free to contact us.
