The "R-T Method" is a stainless steel waterproofing technique that was introduced from the Swedish company Rostfri a-Tak in 1980 and has since evolved uniquely in our company. Today, while maintaining its reliable water tightness, it has been adopted in many representative buildings in our country as an element that composes aesthetically rich roofs. By continuously welding sheets of stainless steel, which have excellent weather resistance, through seam welding, we can ensure reliable water tightness. If long-term weather resistance is required, the option of using titanium sheets is also available. 【Features】 ■ Complete water tightness through welding ■ Long-term maintenance-free ■ Achieves aesthetically rich roofs ■ Constrained method (our unique method) ■ Energy-saving through external insulation construction, etc. ■ Compatible with wooden substrates ■ Installation of solar panels and rooftop greening is possible with dedicated fittings *For more details, please download the PDF or feel free to contact us.

• Special Construction Method

"High Tuff EG" is a comprehensive system that includes total design from the base deck plate, insulation board, High Tuff EG sheet, to accessories (High Tuff Metal), all constructed by our qualified professionals with responsibility. The High Tuff EG sheet uses a waterproof sheet made of ethylene propylene rubber as the main material, laminated with a strong polyester mesh, excelling in "weather resistance, impact resistance, and wind pressure resistance," while also considering the global environment. Additionally, by employing a mechanical fastening method that secures the sheet and insulation board with dedicated fasteners, and a hot air fusion method that integrates the overlapping parts of the sheet with hot air, we have eliminated issues such as bubbling and peeling of the waterproof sheet, which are drawbacks of conventional roofing waterproofing methods.
