High durability handrail "PT type"

Excellent corrosion resistance, durability, and scratch resistance! Environmentally friendly steel pipes that achieve long service life even in harsh conditions!

Chubu Nippon Highway Engineering Nagoya Co., Ltd. (Engineering Nagoya)'s "PT type" is a handrail with a structure that possesses excellent corrosion resistance and durability, achieving a long lifespan even in harsh environments such as audit paths within tunnels. Compared to conventional hot-dip galvanized steel pipes (our products), it exhibits exceptional resistance to red rust. Additionally, from the perspective of "achieving high corrosion resistance with a small amount of coating" and "ensuring a long lifespan," it can be considered an environmentally friendly, chrome-free, resource-saving type of steel pipe. 【Features】 ■ Achieves long lifespan even in harsh environments ■ Excellent corrosion resistance, durability, and scratch resistance ■ High corrosion resistance with a small amount of coating ■ Environmentally friendly, chrome-free, resource-saving type of steel pipe *For more details, please refer to the PDF document or feel free to contact us.

basic information

[Investigation Results of Red Rust Formation] [Salt Spray Test (JIS Z 2371) Corrosion Resistance Test Results] (Foundation) Japan Weathering Test Center ■ The weld bead cut surface of ZAM steel pipes has undergone a special thermal spraying treatment, ensuring high corrosion resistance is maintained throughout the entire steel pipe. ■ The bead area on the inner surface of ZAM steel pipes is also protected from corrosion due to the sacrificial corrosion effect and a dense zinc-based protective film containing Al and Mg. *For more details, please refer to the PDF document or feel free to contact us.*
