POSCO Vietnam is taking the lead in eco-friendly low-carbon management with INNOVILT products, the eco-friendly steel products for construction. POSCO Vietnam donated the PosMAC Barrier, an INNOVILT certified product, to the local government of Pumi on 21 July and installed at a tree in Vietnam Veterans Memorial Park. PosMAC Barrier is a roadside tree guard made of PosMAC, highly corrosion-resistant steel, that continuously supplies air and moisture to the soil and prevents plant roots from uplifting which can destroy sidewalk blocks. In other words, it stores rainwater and retains moisture in the soil to help the roots grow well.
The average annual precipitation in Vietnam is 1500~2000mm, which is higher than the average annual precipitation of 1200mm in Korea last year, but there are distinct dry and rainy seasons. In the rainy season, 80-90% of the annual precipitation is concentrated, but in the dry season, it is too dry that the ground is even cracked. Also, due to the high temperature, there is inevitably less moisture in the soil and plants. In particular, the soil organic matter is rapidly decomposed in the center of the city due to high temperature so the organic matter in the soil is far insufficient.
In Vietnam, due to the poor soil, the growth condition of trees is not good. Also, the destruction of urban infrastructure can be seen everywhere due to severe root uplift. PosMAC Barrier was an essential product for roadside trees in Vietnam as it can store rainwater as a water supply block to keep the soil moist and help the roots grow well. In addition, it was the most suitable product for the current situation as it provides an optimal growth environment for roadside trees and prevents urban heat island.
The upper body of the product exposed to the outside is PosMAC, high-strength, high-corrosion-resistant steel of POSCO and covered in detail about the water tank for collecting rainwater, the EPP filter that guards off foreign body, and the pipe that supplies stored water to the soil and the roots.
Phú M? Tân Thành Bà R?a Vung Tàu based POSCO Vietnam is is a Cold Rolling Mill Complex with pickling, cold-rolling, electrolytic cleaning and annealing plants to produce 1.2 million tonnes CR per year, 700,000 tonnes CRCA & 500,000 tonnes CRFH.
