Metro Build
1 / 5
Design standards compatibility: Design standards are not compatible with local specifications? Our advantage: team engineers and others are familiar with local specifications and design.
Installation Support: Worry about the lack of installation guidance? Our advantage: provide comprehensive installation drawings, etc.
Specifications: steel grade, design load, seismic grade, wind grade, fire rating requirements, etc.
Main Steel: Q355B / Q235B High Strength Structural Steel → Advantage: Ensure structural safety and stability in accordance with international standards.
Surface treatment: hot dip galvanizing / antirust paint (specify thickness and standard) → Advantage: excellent anti-corrosion properties and rust prevention, prolonging the service life of the building and reducing maintenance costs.
