II. Material Selection & Procurement – Strict Selection of High-Quality Materials, Full-Process Controllability
Guarantee quality from the source to create highly durable steel structure products.
Scientific Material Selection: Recommend high-quality steel such as Q235B and Q355B, or special materials like weather-resistant and fire-resistant steel according to structural requirements, and provide material certificates.
Supply Chain Guarantee: Establish strategic cooperation with well-known domestic and foreign steel mills, reduce costs through centralized procurement, and ensure on-time material delivery with zero inventory backlog.
Strict Quality Inspection: Conduct multi-dimensional testing (including strength, composition, and anti-corrosion performance) before materials enter the production line to prevent substandard materials from flowing into the production process.
