'Stainless steel not made for construction'
Its high cost in construction projects, and intended functionality for sensitive areas, makes stainless steel an unsuitable building material, an expert told CWO
Project teams must refrain from using stainless steel as a construction product, an industry expert told ConstructionWeekOnline (CWO).
Dr Salem Faza, president of MMFX Steel DMCC, said the product is not intended for construction activities, adding that its high cost must also discourage its use as a building material.
"Stainless steel is not made for reinforcement and construction work, and instead meant to be used in highly sensitive areas, such as hospitals," Faza continued.
MMFX's portfolio includes notable projects in the UAE, the capital's Al Maryah Island, where its product was used for sea wall protection.
Faza told CWO that the firm's products were picked for Al Maryah Island since the project team required materials that would sustain contact with water and last longer than 75 years.
The company also provided its ChromX 9100 material as steel reinforcement for Jewel of the Creek’s 750m protection walls, replacing the Grade 316 stainless steel reinforcing originally specified for the structure.
The walls, designed at 460 mega pascal (MPa), are directly exposed to seawater and have been constructed to protect the internal basement walls of the project’s towers.
MMFX manufactures a corrosion-resistant product that has been produced by adding chromium to increase its intrinsic strength and adjust its micro-structure.
The company's products, Faza explained, also help reduce congestion on-site and increase the pace of construction.
Faza's insights will be published as part of a marine sector analysis in Construction Week #659 (10 June, 2017).
