An advanced version of the GIR construction method that uses specially shaped forged rods! The rods themselves elongate to ensure high toughness.
We would like to introduce the "GTR (Glued in Toughness Rod) construction method." "Glued-in Rod connection (steel rod insertion adhesive connection)" is a method where a hole is drilled into wooden members, a steel rod is inserted, and resin adhesive is filled to bond the members together. This construction method is an advanced version of the GIR method, using specially shaped forged rods. The rods themselves extend to ensure high toughness. 【Advantages of GIR connection】 ■ High rigidity and high strength ■ No play ■ Connectors are not visible, providing excellent design aesthetics ■ Simple installation *For more details, please refer to the PDF document or feel free to contact us.
