Petrochemical and Nuclear Power Sectors Drive Demand for High-Specification Steel Grating and Manhole Covers
The global petrochemical and nuclear power industries remain among the largest consumers of industrial steel grating and specialized manhole covers. As refinery expansion projects accelerate across Asia and the Middle East, and as nuclear power construction resumes in several countries, procurement of high-specification structural steel products has intensified.
Petrochemical Sector Requirements
Large-scale refinery and petrochemical complex projects — such as those underway in Saudi Arabia, Oman, Malaysia, and Indonesia — require steel grating for elevated platforms, pipe racks, access walkways, and trench covers across hundreds of thousands of square meters of facility footprint. Key specification requirements typically include:
- Load ratings of 5.0 kN/m² UDL and above for main process platforms
- Hot-dip galvanized carbon steel or stainless steel 316 for corrosive process areas
- Compliance with project-specific specifications referencing ASME, BS, or AS standards
- Full material traceability with mill test certificates (MTC)
- Detailed fabrication drawings reviewed and approved by the EPC contractor
Nuclear Power Plant Applications
Nuclear power plants impose the most stringent material and quality requirements of any industrial sector. Steel grating used in nuclear facilities must meet nuclear QA program (NQA-1 or equivalent) requirements, with full documentation chains from raw material sourcing through fabrication, inspection, and delivery. Manhole covers for nuclear plant utility networks must meet specific load and seismic resistance criteria.
Chinese manufacturers with established track records at domestic nuclear facilities — including Tianwan, Haiyang, and Shidaowan — are increasingly competitive in international nuclear project tenders due to demonstrated quality systems and project execution capability.
Daxing has supplied steel grating and manhole covers to major petrochemical projects including ExxonMobil Huizhou, Shell Huizhou, Zhenhai Refinery, and nuclear projects including Tianwan and Haiyang Power Plants. Contact us at ytdaxing@sina.com for project inquiries.
