Wooden barn-style stair construction【Alternative to log and simulated wood stairs】No piling required!
No need for pile driving work! By using high-durability materials and preventing soil runoff in the stepping area, it is possible to reduce cycle costs!
The "Wooden Storage-style Stair Construction" improves workability during installation compared to traditional log stair construction, achieving long-term durability. It reduces maintenance frequency and lowers lifecycle costs. Additionally, it excels over artificial wood in terms of aesthetics and wood utilization. By deeply impregnating wood with anti-decay agents, long-term durability has been achieved. The estimated lifespan based on decay test results is over 50 years. This is a frame-style stair construction assembled with horizontal and vertical materials in a lattice pattern, allowing the use of site-generated soil, stone, chips, etc., in the tread area. Since it is a frame construction method, piling is unnecessary. Because of the frame construction method, soil and gravel in the tread area do not wash away during rain. By adjusting the tread surface, it can accommodate various slopes. The riser can be raised by adding soil to heights of 160 to 210 mm, and the tread surface can be adjusted from 200 to 500 mm. 【Features】 ■ No piling work required like traditional log stair construction ■ Easy installation by simply placing pre-assembled products on site ■ Tread surface can be adjusted by sliding the upper frame ■ Can be adapted to the slope of the stairs ■ The frame construction method prevents runoff from the tread area *For more details, please refer to the PDF document or feel free to contact us.
